Certain Significant Risks and Uncertainties
We operate in a dynamic industry and, accordingly, can be affected by a variety of factors, which are uncertain and difficult to predict. For example, we believe that potential changes in any of the following areas may have a significant impact on us in terms of our future financial position, results of operations or cash flows: the health and stability of the economy and United States residential real estate industry, including changes in inflationary conditions, interest rates, housing availability and affordability, labor shortages and supply chain issues; our ability to navigate industry changes, including as a result of past, pending or future lawsuits, settlements or government investigations; uncertainties related to policy changes, enforcement priorities, or government shutdowns at the federal and state levels; our ability to manage advertising, product inventory and pricing, and to maintain relationships with our real estate partners; our ability to comply with current and future rules and requirements promulgated by NAR, MLSs, or other real estate industry groups or governing bodies, and to maintain or establish relationships with listing and data providers; changes to our rights to use or timely access listing data, or to the quality or quantity of such listing data; our investment of resources to pursue strategies and develop new products and services that may not prove effective or that are not attractive for customers and real estate partners or that do not allow us to compete successfully; our ability to operate and grow the mortgage operations of Zillow Home Loans, our affiliate lender, including the
ability to obtain or maintain sufficient financing and resell originated mortgages on the secondary market; the duration and impact of natural disasters, climate change, geopolitical events, and other catastrophic events (including public health crises) on our ability to operate, demand for our products or services, or general economic conditions; outcomes of legal proceedings and government investigations; our ability to attract, engage, and retain a highly skilled workforce; protection of Zillow Group’s information and systems against security breaches or disruptions in operations; reliance on third-party services to support critical functions of our business; protection of our brand and intellectual property; and changes in laws or government regulation affecting our business, among other things.

Summary of Significant Accounting Policies Summary of Significant Accounting Policies
Basis of Presentation
The accompanying consolidated financial statements include Zillow Group, Inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These consolidated financial statements have been prepared in conformity with GAAP.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. On an ongoing basis, we evaluate our estimates, including those related to the accounting for certain revenue offerings, amortization period and recoverability of contract cost assets, website and software development costs, recoverability of long-lived assets and intangible assets, share-based compensation, income taxes, business combinations, including the initial and subsequent fair value measurements of assets (primarily intangible assets), liabilities and contingent consideration, and the recoverability of goodwill, among others. To the extent there are material differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected. The health of the housing market and the broader economy may result in additional uncertainty with respect to estimates, judgments and assumptions, which may materially impact the estimates previously listed, among others.
Concentrations of Credit Risk
Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents, investments, accounts receivable and mortgage loans held for sale. We place cash and cash equivalents and investments with major financial institutions, which management assesses to be of high credit quality, to limit the exposure of our investments to credit risk.
Credit risk with respect to accounts receivable is dispersed due to the large number of customers. There were no customers that comprised 10% or more of our total accounts receivable as of December 31, 2025 or 2024. Further, our credit risk on accounts receivable is mitigated by the relatively short payment terms that we offer. Collateral is not required for accounts receivable. We maintain an allowance for doubtful accounts such that receivables are stated at net realizable value.
Similarly, our credit risk on mortgage loans held for sale is dispersed due to a large number of customers and is mitigated by the fact that we typically sell mortgages on the secondary market within a relatively short period of time after the loan is originated.
Cash and Cash Equivalents
Cash includes demand deposits with banks or financial institutions. Cash equivalents include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Our cash equivalents represent investments with original maturities of three months or less. We regularly maintain cash in excess of federally insured limits at financial institutions.
Short-term Investments
Our investments consist of fixed income securities, which include U.S. government treasury securities, investment grade corporate securities, U.S. government agency securities, and commercial paper. The investments are available to support current operations and are classified as short-term investments measured at fair value. Our investment policy only allows for purchases of investment-grade securities and provides guidelines on concentrations to ensure minimum risk of loss. We evaluate whether unrealized losses on available-for-sale debt securities are the result of credit worthiness of the securities held
or other non-credit related factors. If an unrealized loss is the result of credit quality factors, we recognize an allowance reflective of our current estimate of credit losses expected to be incurred over the life of the financial instrument on a specific identification basis upon initial recognition and at each reporting period. If a reduction in value is a result of other factors, we continue to classify the losses in comprehensive loss unless either we intend to sell the security or it is more likely than not we will be required to sell the security. We did not identify any unrealized loss positions in our available-for-sale securities that were the result of credit losses as of December 31, 2025 or 2024. Additionally, we have the ability to hold our investments to maturity and more likely than not will not be required to sell the securities before a recovery of the amortized cost basis has occurred.
Restricted Cash
Restricted cash primarily consists of amounts used to fund customer home purchases in our mortgage origination operations.
Mortgage Loans Held for Sale
Mortgage loans held for sale include residential mortgages originated for sale in the secondary market in connection with our mortgage origination operations. We have elected the fair value option for all mortgage loans held for sale as election of this option allows for a better offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without having to apply complex hedge accounting provisions. Mortgage loans held for sale are initially recorded at fair value based on either sale commitments or current market quotes and are adjusted for subsequent changes in fair value until the loans are sold. Net origination costs and fees associated with mortgage loans are recognized as incurred. We sell substantially all of the mortgages we originate and the related servicing rights to third-party purchasers. Interest income is earned from the date a mortgage loan is originated until the loan is sold and is classified within other income, net in the consolidated statements of operations.
Generally, mortgage loans originated are sold within a short period of time in the secondary mortgage market on a servicing released, nonrecourse basis, which limits exposure to nonperformance by loan buyer counterparties. However, we remain liable for certain limited representations and warranties related to loan sales, such as non-compliance with defined loan origination or documentation standards, including misstatement in the loan documents, early payoff or default on early payments. Mortgage investors could seek to have us buy back loans or compensate them for losses incurred on mortgages we have sold based on claims that we breached our limited representations and warranties. We record a reserve for probable losses in connection with the sale of mortgage loans within accrued expenses and other current liabilities in the consolidated balance sheet.
Loan Commitments and Related Derivatives
We are party to IRLCs, which are extended to borrowers who have applied for loan funding and meet defined credit and underwriting criteria in connection with our mortgage origination operations. IRLCs are accounted for as derivative instruments recorded at fair value with gains and losses recognized in revenue in the consolidated statements of operations. We manage our interest rate risk related to IRLCs and mortgage loans held for sale through the use of derivative instruments, generally forward contracts on MBSs, which are commitments to either purchase or sell a financial instrument at a future date for a specified price, and mandatory loan commitments, which are an obligation by an investor to buy loans at a specified price within a specified time period. We do not enter into or hold derivatives for trading or speculative purposes, and our derivatives are not designated as hedging instruments. Changes in the fair value of our derivative financial instruments are recognized in revenue in our consolidated statements of operations, and the fair values are reflected in other current assets or other current liabilities, as applicable. Refer to Note 3 to our consolidated financial statements for additional information regarding IRLCs and related derivatives.
There are no material credit-risk-related contingent features within our derivative agreements, and counterparty risk is considered minimal. Gains and losses on IRLCs are substantially offset by corresponding gains or losses on forward contracts on MBSs and mandatory loan commitments. We are generally not exposed to variability in cash flows of derivative instruments for more than approximately 90 days.
Contract Balances
Accounts receivable represent our unconditional right to consideration. Accounts receivable are generally due within 30 days and are recorded net of the allowance for doubtful accounts. The allowance for doubtful accounts represents our estimate of expected credit losses over the contractual life of the accounts receivable. To evaluate the adequacy of our allowance for doubtful accounts each reporting period, we analyze the accounts receivable balances with similar risk characteristics on a
collective basis, considering factors such as the aging of receivable balances, payment terms, historical loss experience, current information and future expectations. Changes to the allowance for doubtful accounts are adjusted through credit loss expense, which is included in general and administrative expenses in the consolidated statements of operations.
Contract assets represent our right to consideration in exchange for goods and services that we have transferred to the customer when that right is conditional on something other than the passage of time. Contract assets are primarily related to our Zillow Preferred (formerly “Flex”), Pay-Per-Lease and StreetEasy Experts offerings, whereby we estimate variable consideration based on the expected number of real estate transactions to be closed for Zillow Preferred and StreetEasy Experts, and qualified leases to be secured for Pay-Per-Lease. We recognize revenue when we satisfy our performance obligations under the corresponding contracts. The current portion of contract assets are recorded within prepaid expenses and other current assets and the long-term portion of contract assets are recorded within other assets in our consolidated balance sheets.
Contract liabilities consist of deferred revenue, which relates to payments received in advance of performance under a revenue contract. Deferred revenue is primarily related to prepaid advertising fees received or billed in advance of satisfying our performance obligations and prepaid but unrecognized subscription revenue. Deferred revenue is recognized when or as we satisfy our obligations under contracts with customers.
Contract Cost Assets
We capitalize certain incremental costs of obtaining contracts with customers which we expect to recover. These costs relate to commissions paid to sales personnel, primarily for our Premier Agent and Rentals products. As a practical expedient, we recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that we otherwise would have recognized is one year or less. Capitalized commission costs are recorded as contract cost assets in our consolidated balance sheets. Contract cost assets are amortized to expense on a straight-line basis over a period that is consistent with the transfer to the customer of the products or services to which the asset relates, generally the estimated life of the customer relationship. Amortization expense related to contract cost assets is included in sales and marketing expenses in our consolidated statements of operations. In determining the estimated life of our customer relationships, we consider quantitative and qualitative data, including, but not limited to, historical customer data, recent changes or expected changes in product or service offerings and changes in how we monetize our products and services.
We monitor our contract cost assets for impairment and recognize an impairment loss in the consolidated statements of operations to the extent the carrying amount of the asset recognized exceeds the amount of consideration that we expect to receive in the future and that we have received but have not recognized in revenue less the costs that relate directly to providing those goods or services that have not yet been recognized as expenses. For the years ended December 31, 2025, 2024 and 2023, we did not record any material impairment losses to our contract cost assets.
Property and Equipment
Property and equipment is recorded at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. The useful lives are as follows:
 
Computer equipment  
3 years
Office equipment, furniture and fixtures  
5 to 7 years
Leasehold improvements  Shorter of expected useful life or lease term
Maintenance and repair costs are expensed as incurred. Major improvements, which extend the useful life of the related asset, are capitalized. Upon disposal of a fixed asset, we record a gain or loss based on the difference between the proceeds received and the net book value of the disposed asset. We remove fully depreciated property and equipment from the cost and accumulated depreciation amounts disclosed.
Website and Software Development Costs
Costs incurred in the preliminary stages of website and software development are expensed as incurred. Once an application has reached the development stage, internal and external costs, if direct and incremental and deemed by management to be significant, are capitalized in property and equipment and amortized on a straight-line basis over their estimated useful lives. Maintenance and enhancement costs, including those costs in the post-implementation stages, are typically expensed as incurred, unless such costs relate to substantial upgrades and enhancements to the website or software that result in added functionality, in which case the costs are capitalized and amortized on a straight-line basis over their estimated
useful lives. Amortization expense related to capitalized website and software development costs is included in cost of revenue in our consolidated statements of operations.
Capitalized development activities placed in service are amortized over the expected useful lives of those releases, currently estimated at three to five years. The estimated useful lives of website and software development activities are reviewed frequently and adjusted as appropriate to reflect upcoming development activities that may include significant upgrades and/or enhancements to the existing functionality. We remove fully amortized website and software development costs from the cost and accumulated amortization amounts disclosed.
Construction-in-progress primarily consists of website and software development costs that are capitalizable, but for which the associated applications have not been placed in service.
Leases
Our lease portfolio is primarily composed of operating leases for our office space. We determine whether a contract is or contains a lease at inception of the contract. Our operating leases are included in right of use assets and lease liabilities in our consolidated balance sheets. We do not have any material financing leases.
Right of use assets represent our right to use an underlying asset during the lease term and lease liabilities represent our obligation to make lease payments. Right of use assets and lease liabilities are recognized at the lease commencement date based on the present value of the total lease payments contracted but not yet paid, including lease incentives not yet received, with the right of use assets further adjusted for any prepaid or accrued lease payments, lease incentives received and/or initial direct costs incurred.
We have lease agreements that include both lease components (e.g., fixed rent) and non-lease components (e.g., common area maintenance). For such leases, we account for the lease and non-lease components as a single component. Certain lease arrangements also include variable payments for costs such as common-area maintenance, utilities, taxes or other operating costs, which are based on a percentage of actual expenses incurred or a fluctuating rate which is unknown at the inception of the contract. These variable lease payments are excluded from the measurement of the right of use assets and lease liabilities.
Our leases have remaining lease terms ranging from approximately four years to seven years, most of which include one or more options to extend the lease term. The renewal options can generally extend the lease term for up to an additional one to five years. When determining if a renewal option is reasonably certain of being exercised at lease commencement, we consider several factors, including but not limited to, contract-based, asset-based and entity-based factors. We reassess the term of existing leases if there is a significant event or change in circumstances within our control that affects whether we are reasonably certain to exercise an option to extend a lease. Examples of such events or changes include construction of significant leasehold improvements or other modifications or customizations to the underlying asset, relevant business decisions or subleases. As of December 31, 2025, we have concluded that our renewal options are not reasonably certain of being exercised, therefore, renewal options are not included in the right of use assets and lease liabilities.
As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. We apply a portfolio approach for determining the incremental borrowing rate based on the applicable lease terms and the current economic environment.
We recognize lease expense for operating leases on a straight-line basis over the lease term. Variable lease payments are generally recognized when incurred. For leases with an initial term of 12 months or less, we recognize the associated lease payments in the consolidated statements of operations on a straight-line basis over the lease term. These expenses are included in general and administrative expenses in the consolidated statements of operations.
Recoverability of Goodwill
Goodwill is measured as the excess of consideration transferred for an acquired business over the net of the acquisition date fair values of the assets acquired and the liabilities assumed, and is not amortized. We assess the impairment of goodwill at the reporting unit level on an annual basis, in our fourth quarter, or whenever events or changes in circumstances indicate that goodwill may be impaired. In our evaluation of goodwill, we initially perform a qualitative assessment to determine whether the existence of events or circumstances indicates that it is more likely than not that the carrying value of each reporting unit is greater than its fair value. If it is more likely than not that the carrying value of a reporting unit is greater than its fair value, we perform a quantitative assessment and an impairment charge is recorded in our statements of operations if the carrying value of the reporting unit exceeds its fair value. During the years ended December 31, 2025, 2024 and 2023, we did not record any impairments related to goodwill.
Our chief operating decision maker (“CODM”) is our chief executive officer (“CEO”) who manages our business, makes operating decisions and evaluates operating performance on the basis of the company as a whole. This aligns to our ongoing growth strategy and our intent to provide integrated customer solutions for all tasks and services related to facilitating real estate transactions. Accordingly, we have a single operating and reportable segment.
Intangible Assets
We purchase and license data content from multiple data providers. In some instances, we retain perpetual rights to this information after our contract with a vendor ends; in other instances, the information and data are licensed only during the fixed term of the agreement.
We capitalize payments made to third parties for data licenses that we expect to recover through generation of revenue and margins. We amortize capitalized purchased content on a straight-line basis using our best estimate of the useful life of the asset, which ranges from three to seven years. Under certain other data agreements, the underlying data is obtained on a subscription basis with consistent monthly or quarterly recurring payment terms over the contractual period. Upon the expiration of such arrangements, we no longer have the right to access the related data, and therefore, the costs incurred under such contracts are not capitalized and are expensed as payments are made.
We also capitalize costs related to the license of certain internal-use software from third parties, including certain licenses of software in cloud computing arrangements. Additionally, we capitalize costs incurred during the application development stage related to the development and customization of internal-use software and enterprise cloud computing services. We expense costs as incurred related to the planning and post-implementation phases of development. Capitalized internal-use software costs are amortized on a straight-line basis over the estimated useful life of the asset, which is currently three to five years.
Intangibles-in-progress include capitalizable development costs incurred before the related software is placed in service.
We also have intangible assets for customer relationships, developed technology, and trade names and trademarks which we recorded in connection with acquisitions and strategic partnerships. Purchased intangible assets with a determinable economic life are carried at cost less accumulated amortization. These intangible assets are amortized over the estimated useful life of the asset on a straight-line basis.
For each of the intangible assets described above, we have removed fully amortized assets from the cost and accumulated amortization amounts disclosed.
Recoverability of Intangible Assets with Definite Lives and Other Long-Lived Assets
We evaluate intangible assets and other long-lived assets, including our lease right of use assets, for impairment whenever events or circumstances indicate that they may not be recoverable. Recoverability is measured by comparing the carrying amount of an asset group to future undiscounted net cash flows expected to be generated. We group assets for purposes of such review at the lowest level for which identifiable cash flows of the asset group are largely independent of the cash flows of the other groups of assets and liabilities. If this comparison indicates impairment, the amount of impairment to be recognized is calculated as the difference between the carrying value and the fair value of the asset group.
Business Combinations
We recognize identifiable assets acquired and liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions for the preliminary purchase price allocation process to value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that we identify adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations. We recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined.
We record contingent consideration at its preliminary estimated fair value at the date of acquisition. The current portion of contingent consideration is recorded within accrued expenses and other current liabilities, and the long-term portion is recorded within other long-term liabilities in our consolidated balance sheets. The fair value of contingent consideration is remeasured each reporting period. Measurement period adjustments, if any, to the preliminary estimated fair value as of the
acquisition date are recorded to goodwill during the measurement period, which may be up to one year from the acquisition date. Changes in fair value as a result of updated assumptions after the acquisition date are recorded in general and administrative expenses in the consolidated statements of operations.
Revenue Recognition
We recognize revenue when or as we satisfy our performance obligations by transferring control of the promised products or services to our customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those products or services.
As a practical expedient, we do not adjust the promised amount of consideration for the effects of a significant financing component, as the period between our transfer of a promised product or service to a customer and when the customer pays for that product or service is generally one year or less, with the exception of certain of our pay for performance products, including Zillow Preferred and StreetEasy Experts, whereby we may not receive payment for more than a year after control of the promised products or services is transferred to our customers. In these cases, however, because a substantial portion of the consideration is variable, we have concluded the contracts do not include a significant financing component.
We do not disclose the transaction price related to remaining performance obligations for (i) contracts with an original expected duration of one year or less or (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for performance completed to date. The remaining duration over which we satisfy our performance obligations is generally less than one year.
Our revenue is classified into four categories: Residential, Mortgages, Rentals and Other. Our “For Sale revenue” subtotal includes our Residential and Mortgages revenue categories and represents our revenue from participation in residential real estate purchase and sale transactions.
Residential. Residential revenue includes revenue generated from our agent and software offerings and revenue derived from our New Construction marketplace and StreetEasy for sale product offerings. Agent offerings include Premier Agent market-based pricing, Zillow Preferred (formerly Flex) and Zillow Showcase. Software offerings primarily include Follow Up Boss, dotloop, and ShowingTime.
Premier Agent advertising products, which include the delivery of validated customer connections, or leads, are offered on a share of voice (“market-based pricing”) and pay for performance (“Zillow Preferred”) basis. Connections are delivered when consumer contact information is provided to Premier Agent partners. We do not promise any minimum or maximum number of connections to customers for either market-based pricing or Zillow Preferred.
For Premier Agent market-based pricing, we control when and how many connections to deliver based on a customer’s share of voice. A Premier Agent partner’s share of voice in a zip code is determined by their proportional monthly prepaid spend in that zip code as a percentage of the total monthly prepaid spend of all Premier Agent partners in that zip code, and determines the proportion of connections a Premier Agent partner receives. The number of connections delivered for a given spend level is dynamic; as demand for advertising in a zip code increases or decreases, the number of connections delivered to a Premier Agent partner in that zip code decreases or increases accordingly.
We recognize revenue related to Premier Agent market-based pricing products and services based on the monthly prepaid spend recognized on a straight-line basis during the monthly billing period over which the products and services are provided. This methodology best depicts how we satisfy our performance obligations to customers, as we continuously transfer control of the performance obligations to the customer over time. We have not allocated the transaction price to each performance obligation within our Premier Agent market-based pricing arrangements, as the amounts recognized would be the same irrespective of any allocation.
Our pay for performance pricing model, “Zillow Preferred,” was introduced as the next chapter for our Flex program in the fourth quarter of 2025, and is available in certain markets to select partners. With the Zillow Preferred model, Premier Agent partners are provided with leads and pay a performance advertising fee when a real estate transaction is closed with one of the leads, generally within two years. With this pricing model, the transaction price represents variable consideration, as the amount to which we expect to be entitled varies based on the number of leads that convert into real estate transactions and the value of those transactions. We estimate variable consideration and record revenue over time as our performance obligations, or leads, are transferred. We do not believe that a significant reversal in the amount of cumulative revenue recognized will occur once the uncertainty related to the number of transactions closed is subsequently resolved. We record a contract asset for our estimate of the consideration to which we will be entitled when the right to the consideration is conditional. When the right to consideration becomes unconditional, upon the close of a real estate transaction, we reclassify amounts to accounts receivable.
Zillow Showcase is an advertising and marketing solution which allows real estate agents to advertise an enhanced listing on our mobile apps and websites. Customers pay for Zillow Showcase credits upfront, and each credit allows the customer to apply the Showcase listing treatment to one active for-sale listing. Zillow Showcase revenue is recognized by measuring our progress towards satisfaction of our performance obligations, primarily the enhanced listing features, using the output method of results achieved.
Follow Up Boss is a SaaS solution allowing real estate agents, teams and brokerages to manage real estate leads from the initial contact through the home buying or selling process. Follow Up Boss revenue is primarily billed in advance on a monthly basis and recognized ratably over the contract period, aligning to the satisfaction of our performance obligations.
Dotloop is a real estate transaction management SaaS solution. ShowingTime primarily generates revenue through Appointment Center, which is a SaaS and call center solution allowing real estate agents, brokerages and multiple listing services to efficiently schedule real estate viewing appointments on behalf of their customers. Both dotloop and Appointment Center revenue are primarily billed monthly in advance and recognized ratably over the contract period, aligning to the satisfaction of our performance obligations.
Our new construction marketing solutions allow home builders to showcase their available inventory to home shoppers. New construction revenue primarily includes revenue generated by advertising sold to builders on a cost per residential community basis whereby we recognize revenue on a straight-line basis during the contractual period over which the communities are advertised on our mobile apps and websites. New construction revenue also includes revenue generated on a cost per impression basis whereby we recognize revenue as impressions are delivered to users interacting with our mobile apps and websites, which is the amount for which we have the right to invoice. Consideration for new construction products is billed in arrears.
StreetEasy for-sale revenue primarily consists of our StreetEasy Experts and StreetEasy subscription offerings. StreetEasy Experts is our pay for performance pricing model available in the New York City market for which agents and brokers are provided with leads at no initial cost and pay a performance referral fee only when a real estate purchase transaction is closed with one of the leads. Under the StreetEasy Experts pricing model, the transaction price represents variable consideration, as the amount to which we expect to be entitled varies based on the number of leads that convert into real estate transactions and the value of those transactions. We estimate variable consideration based on the expected number of closed transactions during the period. We do not believe that a significant reversal in the amount of cumulative revenue recognized will occur when the uncertainty related to the number of transactions closed is subsequently resolved. We record a corresponding contract asset for the estimate of variable consideration for StreetEasy Experts when the right to the consideration is conditional. When the right to consideration becomes unconditional upon the close of a real estate transaction, we reclassify amounts to accounts receivable. Revenue generated through StreetEasy subscription offerings includes the sale of advertising and a suite of tools to developers, property managers, agents and other real estate professionals. StreetEasy subscription customers pay in advance on a cost per property basis. We recognize revenue for our StreetEasy subscription offerings on a straight-line basis over the contractual listing period which aligns to our satisfaction of performance obligations.
Rentals. Rentals revenue includes the sale of advertising and a suite of tools to rental professionals, landlords and other market participants under the Zillow and StreetEasy brands. Rentals revenue includes revenue generated by advertising sold to property managers, landlords and other rental professionals on a cost per lease, listing or impression basis or for a fixed fee for certain advertising packages. We recognize revenue as leads or impressions are provided to rental professionals, or as rental listings are published on our mobile apps and websites, which is the amount for which we have the right to invoice. We bill our fixed fee rentals products monthly in arrears and recognize revenue ratably over the contract period, aligning to the satisfaction of our performance obligations. The number of leases generated through our rentals Pay-Per-Lease product during the period is accounted for as variable consideration. We estimate the amount of consideration based on the expected number of qualified leases secured during the period. We do not believe that a significant reversal in the amount of cumulative revenue recognized will occur once the uncertainty related to the number of leases secured is subsequently resolved. We record a contract asset for the estimate of variable consideration for Pay-Per-Lease when the right to the consideration is conditional. When the right to consideration becomes unconditional upon the execution of a lease, we reclassify amounts to accounts receivable. Rentals revenue also includes revenue generated from our rental applications product, through which potential renters can submit applications to multiple properties for a flat service fee. Rental applications customers pay upfront and we recognize revenue ratably over the contractual period during which the customer has the right to access and submit the rental application.
Mortgages. Mortgages revenue primarily includes revenue generated by Zillow Home Loans, our affiliated mortgage lender, and marketing products sold to mortgage professionals on a cost per lead basis, primarily our Connect services.
Mortgage origination revenue reflects origination fees on purchase or refinance mortgages and the corresponding sale, or expected future sale, of a loan. When an IRLC is made to a customer, we record the expected gain on sale of the mortgage, plus the estimated earnings from the expected sale of the associated servicing rights, adjusted for a pull-through percentage (which is defined as the likelihood that an IRLC will be originated), as revenue. Revenue from loan origination fees is recognized at the time the related purchase or refinance transactions are completed, usually upon the close of escrow and when we fund the purchase or refinance mortgage loans. Once funded, mortgage loans held for sale are recorded at fair value based on either sale commitments or current market quotes and are adjusted for subsequent changes in fair value until the loan is sold. Origination costs associated with originating mortgage loans are recognized as incurred. We generally sell the mortgages we originate and the related servicing rights to third-party purchasers.
Mortgage loans are sold with limited recourse provisions, which can result in repurchases of loans previously sold to investors or payments to reimburse investors for loan losses. Based on historical experience, discussions with our mortgage purchasers, analysis of the volume of mortgages we originated and current housing and credit market conditions, we estimate and record a loss reserve for mortgage loans held for sale, as well as known and projected mortgage loan repurchase requests. These have historically not been material to our financial statements.
Zillow Group operates Connect through its wholly owned subsidiary, Zillow Group Marketplace, Inc., a licensed mortgage broker. For our Connect cost per lead marketing product, participating qualified mortgage professionals typically make a prepayment to gain access to consumers interested in connecting with mortgage professionals. Mortgage professionals who exhaust their initial prepayment prepay additional funds to continue to participate in the marketplace. We recognize revenue when a user contacts a mortgage professional through our mortgages platform, which corresponds directly to the value of our performance.
Other. Other revenue primarily includes revenue generated from display products, which consist of graphical mobile and web advertising sold on a cost per thousand impressions or cost per click basis to advertisers promoting their brands on our mobile apps and websites. We recognize revenue as clicks occur or as impressions are delivered to users interacting with our mobile apps or websites, which is the amount for which we have the right to invoice.
There were no customers that generated 10% or more of our total revenue in the years ended December 31, 2025, 2024 or 2023.
Cost of Revenue. Cost of revenue consists of expenses related to operating our mobile apps and websites, including associated headcount-related expenses, such as salaries, benefits, bonuses and share-based compensation expense, as well as revenue-sharing costs related to our commercial business relationships, depreciation expense, and costs associated with hosting our mobile apps and websites. Cost of revenue also includes amortization costs related to capitalized website and development activities, amortization of software, amortization of certain intangible assets and other costs to obtain data used to populate our mobile apps and websites, and amortization of certain intangible assets recorded in connection with acquisitions, including developed technology. Cost of revenue also includes credit card fees and ad serving costs paid to third parties, direct costs to provide our rental applications product, and direct costs to originate mortgage loans, including underwriting and processing costs.
Sales and Marketing. Sales and marketing expenses consist of advertising costs and other sales expenses related to promotional and marketing activities, headcount-related expenses, including salaries, commissions, benefits, bonuses and share-based compensation expense for sales, sales support, customer support, including the customer connections team and mortgage loan officers and specialists, marketing and public relations employees, depreciation expense and amortization of certain intangible assets recorded in connection with acquisitions and strategic partnerships, including trade names and trademarks and customer relationships.
Advertising costs are expensed as incurred. For the years ended December 31, 2025, 2024 and 2023, expenses attributable to advertising totaled $165 million, $175 million and $137 million, respectively.
Technology and Development. Technology and development expenses consist of headcount-related expenses, including salaries, benefits, bonuses and share-based compensation expense for individuals engaged in the design, development and testing of our products, mobile apps and websites and the tools and apps that support our products. Technology and development expenses also include equipment and software maintenance costs and depreciation expense.
Research and development costs are expensed as incurred and are recorded in technology and development expenses. For the years ended December 31, 2025, 2024 and 2023, expenses attributable to research and development totaled $553 million, $543 million and $545 million, respectively.
Share-Based Compensation. We measure compensation expense for all share-based awards at fair value on the date of grant and recognize compensation expense over the service period on a straight-line basis for awards expected to vest.
We use the Black-Scholes-Merton option-pricing model to determine the fair value for option awards. In valuing our option awards, we make assumptions about risk-free interest rates, dividend yields, volatility and weighted-average expected lives. We account for forfeitures as they occur. Risk-free interest rates are derived from U.S. Treasury securities as of the option award grant date. Expected dividend yield is based on our historical cash dividend payments, which have been zero to date. The expected volatility for our Class C capital stock is estimated using our historical volatility. The weighted-average expected life of the option awards is estimated based on our historical exercise data.
When determining the grant date fair value of share-based awards, management considers whether an adjustment is required to the observable market price or volatility of the Company’s Class C capital stock used in the valuation as a result of material non-public information.
For issuances of restricted stock units, we determine the fair value of the award based on the market value of our Class C capital stock, as applicable, at the date of grant.

Income Taxes
We use the asset and liability approach for accounting and reporting income taxes, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement and tax bases of assets and liabilities at the applicable enacted tax rates. A valuation allowance against deferred tax assets would be established if, based on the weight of available evidence, it is more likely than not (a likelihood of more than 50%) that some or all of the deferred tax assets are not expected to be realized.
We establish reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit, new tax legislation or the change of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made. Interest and penalties related to unrecognized tax benefits are recorded as income tax expense.
Recently Adopted Accounting Standards
In December 2023, the FASB issued guidance to enhance the income tax rate reconciliation disclosure requirements and to provide clarity on disclosure requirements for income taxes. We adopted this guidance on a prospective basis for the annual period ending December 31, 2025. While the adoption of this guidance has resulted in additional disclosures related to income taxes, it did not have a material impact on our consolidated financial statements. Refer to Note 9 for additional information related to our income tax disclosures.
Recently Issued Accounting Standards Not Yet Adopted
In November 2024, the FASB issued guidance that will require disclosure of specified information about certain costs and expenses included within an entity’s consolidated financial statements. This guidance is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027, and can be applied on a prospective or retrospective basis, with early adoption permitted. We have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.
In September 2025, the FASB issued guidance that modernizes the accounting for internal-use software costs by removing all references to project development stages. Under this guidance, eligible software development costs begin capitalization once management has authorized and committed to funding the project and it is probable the project will be completed and used to perform the function intended. This guidance is effective for annual and interim periods beginning after December 15, 2027, and can be applied on a prospective, retrospective or modified basis, with early adoption permitted. We have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.
In December 2025, the FASB issued guidance that improves the navigability of interim reporting guidance and clarifies when it applies. Under this guidance, entities must disclose events since the end of the last annual reporting period that have a material impact on the entity. This guidance is not intended to change the fundamental nature of interim reporting or expand or reduce current interim disclosure requirements. This guidance is effective for annual and interim periods beginning after December 15, 2027, and can be applied on a prospective or retrospective basis, with early adoption permitted. We have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.

Fair Value Disclosures [Abstract]  
Financial Instruments Financial Instruments
We apply fair value measurements on a recurring and, as otherwise required, on a nonrecurring basis. Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The standards also establish a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1 — Quoted prices in active markets for identical assets or liabilities.
Level 2 — Assets and liabilities valued based on observable market data for similar instruments, such as quoted prices for similar assets or liabilities.
Level 3 — Unobservable inputs that are supported by little or no market activity; instruments valued based on the best available data, some of which is internally developed, and considers risk premiums that a market participant would require.
We apply the following methods and assumptions in estimating our fair value measurements:
Cash equivalents — The fair value measurement of money market funds is based on quoted market prices in active markets (Level 1). The fair value measurement of other cash equivalents is based on observable market-based inputs principally derived from or corroborated by observable market data (Level 2).
Short-term investments — The fair value measurement of our short-term investments is based on observable market-based inputs or inputs that are derived principally from or corroborated by observable market data by correlation or other means (Level 2).
Restricted cash — The carrying value of restricted cash approximates fair value due to the short period of time that amounts are held in escrow (Level 1).
Mortgage loans held for sale — The fair value of mortgage loans held for sale is generally calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics (Level 2).
Forward contracts — The fair value of mandatory loan sales commitments and derivative instruments such as forward sales of MBSs that are utilized as economic hedging instruments is calculated by reference to quoted prices for similar assets (Level 2).
Contingent consideration — In December 2023, Zillow Group acquired Follow Up Boss for $399 million in cash, net of cash acquired, and contingent consideration of up to $100 million, payable over a three-year period upon achievement of certain performance metrics. During the year ended December 31, 2025, we paid $33 million in cash to settle the first earn out payment, most of which represented settlement of the acquisition date fair value. The fair value of the contingent consideration is estimated using a Monte Carlo simulation which considers the probabilities of the achievement of certain performance metrics (Level 3).
The discount rates used in our valuation of contingent consideration are based on our estimated cost of debt and are directly related to the fair value of contingent consideration. An increase in the discount rate, in isolation, would result in a decrease in the fair value measurement. Conversely, a decrease in the discount rate, in isolation, would result in an increase in the fair value measurement. The probabilities of achieving the relevant performance metrics used in our valuation of contingent consideration are directly related to the fair value of contingent consideration, as an increase in the probability, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the probability, in isolation, would result in a decrease in the fair value measurement.
The following table presents the ranges and weighted average unobservable inputs used in determining the fair value of contingent consideration as of the dates presented:

IRLCs — The fair value of IRLCs is calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics. Expired commitments are excluded from the fair value measurement. Since not all IRLCs will become closed loans, we adjust our fair value measurements for the estimated amount of IRLCs that will not close. This adjustment is effected through the pull-through rate, which represents the probability that an IRLC will ultimately result in a closed loan. For IRLCs that are canceled or expire, any recorded gain or loss is reversed at the end of the commitment period (Level 3).
The pull-through rate is based on estimated changes in market conditions, loan stage and historical borrower behavior. Pull-through rates are directly related to the fair value of IRLCs as an increase in the pull-through rate, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the pull-through rate, in isolation, would result in a decrease in the fair value measurement. Changes in the fair value of IRLCs are included within revenue in our consolidated statements of operations.

On February 6, 2025, we entered into a partnership with Redfin Corporation (“Redfin”), making Zillow the exclusive provider of multifamily (properties with 25 or more units) rental listings on Redfin and its sites, including Rent.com and ApartmentGuide.com (together, “Redfin Rental Network”). Pursuant to this rentals partnership, Zillow made a $100 million payment to Redfin in February 2025 that is included in customer relationships in the table above and is being amortized over the estimated useful life of nine years. Zillow also pays Redfin for leads generated through the Redfin Rental Network for an initial period of five years with two optional two-year extensions, subject to the terms of the underlying agreements.
We recorded amortization expense related to intangible assets of $89 million, $77 million and $53 million for the years ended December 31, 2025, 2024 and 2023, respectively.

We have subleases related to certain of our operating leases. For the years ended December 31, 2025, 2024 and 2023, we recognized $6 million, $6 million and $10 million, respectively, of sublease income. For the years ended December 31, 2025, 2024, and 2023, we recognized impairment costs of $2 million, $6 million and $16 million, respectively, within impairment and restructuring costs in our consolidated statements of operations associated with changes in the use of certain office spaces, primarily related to subleases where anticipated sublease income was less than the carrying value of the related asset group.

(1) During the year ended December 31, 2023, we amended our existing office space lease for our corporate headquarters in Seattle, Washington, to provide the landlord the option to terminate a portion of our lease prior to the original lease termination date. In December 2023, the landlord exercised the early termination option for the relevant floors effective June 30, 2024. This modification to the lease term resulted in an immediate reduction in the right of use asset and lease liability of $8 million. We ceased use of the terminated space as of December 31, 2023, and as a result, we accelerated recognition of $14 million of amortization for the related right of use asset during the year ended December 31, 2023.

We utilize master repurchase agreements to provide capital for Zillow Home Loans. The master repurchase agreements provide short-term financing between the issuance of a mortgage loan and when Zillow Home Loans sells the loan to an investor or directly to an agency. The carrying amounts of our master repurchase agreements approximate their fair values because of their short-term nature. The following table summarizes certain details related to our master repurchase agreements as of the dates presented (in millions, except interest rates):

(4) Agreement was amended and renewed on September 5, 2025 to extend the maturity date to September 4, 2026.
(5) Agreement was entered into on June 9, 2025.
In accordance with the master repurchase agreements, the Lenders have agreed to pay Zillow Home Loans a negotiated purchase price for eligible loans, and Zillow Home Loans has simultaneously agreed to repurchase such loans from the Lenders under a specified timeframe at an agreed upon price that includes interest. The master repurchase agreements contain margin call provisions that provide the Lenders with certain rights in the event of a decline in the market value of the assets purchased under the master repurchase agreements. As of December 31, 2025 and 2024, $381 million and $151 million, respectively, in mortgage loans held for sale were pledged as collateral under the master repurchase agreements.
Borrowings on the master repurchase agreements bear interest at a floating rate based on SOFR plus an applicable margin, as defined by the governing agreements. The master repurchase agreements include customary representations and warranties, covenants and provisions regarding events of default. As of December 31, 2025, Zillow Home Loans was in compliance with all financial covenants and no event of default had occurred. The master repurchase agreements are recourse to Zillow Home Loans, and have no recourse to Zillow Group or any of its other subsidiaries.

Settlement of 2024 Notes and Related Capped Call Transactions. The 2024 Notes matured on September 1, 2024. During the period from March 1, 2024 through the close of business on August 29, 2024, holders of the 2024 Notes elected to convert all outstanding 2024 Notes in accordance with the terms of the indenture. We settled these conversions with aggregate cash payments totaling $610 million, which included $608 million in principal repayments, $2 million for accrued interest and a nominal cash payment in lieu of fractional shares, and the issuance of 1.9 million shares of Class C capital stock.
In September 2024, we received 2.1 million shares of Class C capital stock from the settlement of the capped call transactions we entered into in connection with the issuance of the 2024 Notes. Under applicable Washington State law, the acquisition of a corporation’s own shares is not disclosed separately as treasury stock in the financial statements and such shares are treated as authorized but unissued shares. We record acquisitions of our shares of capital stock as a reduction to capital stock at the par value of the shares reacquired, then to additional paid-in capital until it is depleted to a nominal amount, with any further excess recorded to retained earnings. We recorded an offsetting increase to additional paid-in capital for the unwind of the capped call transactions.
Settlement of 2025 Notes. During the year ended December 31, 2023 and in accordance with our Repurchase Authorizations, we repurchased $58 million aggregate principal amount of the 2025 Notes through open market transactions for $57 million in cash, including accrued interest, resulting in an immaterial gain on extinguishment of debt recognized in our consolidated statements of operations. During the year ended December 31, 2024 and in accordance with our Repurchase Authorizations, we repurchased $88 million aggregate principal amount of the 2025 Notes through open market transactions for $89 million in cash, including accrued interest, resulting in an immaterial loss on extinguishment of debt recognized in our consolidated statements of operations. For additional information on the Repurchase Authorizations, see Note 10 under the subsection titled “Share Repurchase Authorizations.” The 2025 Notes matured on May 15, 2025, and we settled the remaining $419 million in aggregate principal amount of the 2025 Notes with cash payments totaling $425 million, which included $419 million in principal repayments, $6 million for accrued interest and a nominal cash payment in lieu of fractional shares, and the issuance of a nominal number of shares of Class C capital stock.
Settlement of 2026 Notes and Related Capped Call Transactions. On October 8, 2024, we submitted notice to the trustee to exercise our right to redeem the remaining $499 million in aggregate principal amount of the 2026 Notes on December 18, 2024 (the “Redemption Date”). Holders of the 2026 Notes elected to convert $498 million of aggregate principal amount prior to the Redemption Date. We settled these conversions with aggregate cash payments totaling $498 million covering principal and cash in lieu of fractional shares, and the issuance of 4.5 million shares of Class C capital stock. In addition, on the Redemption Date, the Company redeemed the remaining $1 million in aggregate principal amount of 2026 Notes that had not been surrendered for conversion at a redemption price in cash equal to 100% of the principal amount of 2026 Notes not converted, plus accrued and unpaid interest on such 2026 Notes from September 1, 2024 to, but excluding, the Redemption Date.
In August 2025, we settled the capped call transactions we entered into in connection with the issuance of the 2026 Notes, resulting in the receipt of approximately 3.1 million shares of Class C capital stock and $38 million in cash.

On July 4, 2025, the One Big Beautiful Bill Act (the “Bill”) was enacted into law. The Bill provides for significant U.S. tax law changes and modifications and makes permanent certain key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation, the expensing of domestic research costs, and the business interest expense limitation. The provisions of the Bill did not have a material impact on our consolidated financial statements for the year ended December 31, 2025.
We are subject to income taxes in the United States (federal and state) and certain foreign jurisdictions. We recorded income tax expense of $2 million, $5 million, and $4 million for the years ended December 31, 2025, 2024, and 2023 respectively, primarily due to state taxes.

Realization of deferred tax assets is dependent upon the generation of future taxable income, if any, the timing and amount of which are uncertain. We have provided a full valuation allowance against the net deferred tax assets as of December 31, 2025 and 2024 because, based on the weight of available evidence, it is more likely than not (a likelihood of more than 50%) that some or all of the deferred tax assets will not be realized. The valuation allowance increased by $51 million and $49 million during the years ended December 31, 2025 and 2024, respectively.
We have accumulated federal net operating losses of approximately $1.8 billion and $1.3 billion, as of December 31, 2025 and 2024, respectively, which are available to reduce future taxable income. We have accumulated tax effected state net operating losses of approximately $70 million and $66 million as of December 31, 2025 and 2024, respectively. Federal net operating losses generated in taxable periods on or before December 31, 2017 have a twenty-year carryforward period and begin to expire in 2036. Federal net operating loss carryforwards generated in taxable years beginning after December 31, 2017
may be carried forward indefinitely, but the deductibility of such net operating loss carryforwards in taxable years beginning after December 31, 2020 is limited to 80% of taxable income. State net operating loss carryforward periods for the various jurisdictions generally range from three years to indefinite-lived and began to expire in 2024. Additionally, we have net research and development credit carryforwards of $250 million and $205 million as of December 31, 2025 and 2024, respectively, which are available to reduce future tax liabilities. The research and development credit carryforwards began to expire in 2025. Under Sections 382 and 383 of the Internal Revenue Code, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes, such as research and development credits, to offset its post-change taxable income or income tax liability may be limited. We have completed a detailed study and concluded there were multiple ownership changes, triggering the application of Section 382 of the Internal Revenue Code. Based on our most recent analysis, we do not currently anticipate any material reduction in our ability to utilize our net operating loss and tax credit carryforwards under these rules.
Our primary income tax jurisdiction is the United States (federal). With limited exceptions for state taxing authorities which are not material to the financial statements, all tax years for which we have filed a tax return remain subject to examination due to the existence of net operating loss carryforwards.

Amended and Restated 2011 Incentive Plan (the “2011 Plan”), which became effective July 19, 2011. Subject to adjustment from time to time as provided in the 2020 Plan, a total of 12 million shares of Class C capital stock are authorized for issuance under the 2020 Plan. In addition, shares previously available for new grants under the 2011 Plan as of June 9, 2020 and shares subject to outstanding awards under the 2011 Plan as of June 9, 2020 that on or after that date cease to be subject to such awards (other than by reason of exercise or settlement of the awards in vested or nonforfeitable shares) are also available for issuance under the 2020 Plan. The number of shares authorized under the 2020 Plan will be increased on the first day of each calendar year, beginning January 1, 2021 and ending on and including January 1, 2030, by an amount equal to the lesser of (a) 5% of our outstanding Class A common stock, Class B common stock and Class C capital stock on a fully diluted basis as of the end of the immediately preceding calendar year and (b) a number of shares determined by our Board. Shares issued under the 2020 plan may be issued from authorized and unissued shares of Class C capital stock. The 2020 Plan is administered by the Compensation Committee of the Board (the “Compensation Committee”). Under the terms of the 2020 Plan, the Compensation Committee may grant equity awards, including incentive or nonqualified stock options, restricted stock, restricted stock units, restricted units, stock appreciation rights, performance shares or performance units to employees, directors and consultants of Zillow Group and its subsidiaries. The Board has also authorized certain senior executive officers to grant equity awards under the 2020 Plan, within limits prescribed by our Board.
Options under the 2020 Plan are granted with an exercise price per share not less than 100% of the fair market value of our Class C capital stock on the grant date, with the exception of substituted option awards granted in connection with acquisitions, and are exercisable at such times and under such conditions as determined by the Compensation Committee. Any portion of an option that is not vested and exercisable on the date of a participant’s termination of service expires on such date. Employees generally forfeit their rights to exercise vested options three months following their termination of employment or
12 months following termination by reason of death, disability or retirement. Options granted under the 2020 Plan expire no later than ten years from the grant date and typically vest over a period of four years.
Restricted stock units granted under the 2020 Plan typically vest over a period of four years. Generally, any portion of a restricted stock unit that is not vested on the date of a participant’s termination of service expires on such date.
In addition to the option awards and restricted stock units typically granted under the 2020 Plan which vest quarterly over four years, during the first quarter of 2023, the Compensation Committee approved option and restricted stock unit awards granted under the 2020 Plan in connection with the 2022 annual review cycle that vest quarterly over three years. The exercisability terms of these equity awards are otherwise consistent with the terms of the option awards and restricted stock units typically granted under the 2020 Plan.
Zillow Group, Inc. Amended and Restated 2011 Incentive Plan
Options and restricted stock units that remain outstanding under the 2011 Plan have vesting and exercisability terms consistent with those described above for awards granted under the 2020 Plan.
Zillow Group, Inc. 2019 Equity Inducement Plan
On August 8, 2019, the 2019 Equity Inducement Plan (“Inducement Plan”) became effective. Subject to adjustment from time to time as provided in the Inducement Plan, 10 million shares of Class C capital stock are available for issuance under the Inducement Plan. Shares issued under the Inducement Plan shall be drawn from authorized and unissued shares of Class C capital stock. The purpose of the Inducement Plan is to attract, retain and motivate certain new employees of the Company and its subsidiaries by providing them the opportunity to acquire a proprietary interest in the Company and to align their interests and efforts to the long-term interests of the Company’s shareholders. Each award under the Inducement Plan is intended to qualify as an employment inducement award pursuant to Listing Rule 5635(c) of the corporate governance rules of the NASDAQ Stock Market. The Inducement Plan is administered by the Compensation Committee. Under the terms of the Inducement Plan, the Compensation Committee may grant equity awards, including nonqualified stock options, restricted stock or restricted stock units or restricted units to new employees of the Company and its subsidiaries.
Options under the Inducement Plan are granted with an exercise price per share not less than 100% of the fair market value of our Class C capital stock on the date of grant, with the exception of substituted option awards granted in connection with acquisitions, and are exercisable at such times and under such conditions as determined by the Compensation Committee. Any portion of an option that is not vested and exercisable on the date of a participant’s termination of service generally expires on such date. Employees generally forfeit their rights to exercise vested options three months following their termination of employment or 12 months following termination by reason of death, disability or retirement. Options granted under the Inducement Plan expire no later than ten years from the grant date and typically vest over a period of four years.
Restricted stock units granted under the Inducement Plan typically vest over a period of four years. In general, any portion of a restricted stock unit that is not vested on the date of a participant’s termination of service expires on such date.
Option Award Repricing
On August 3, 2022, upon recommendation of the Compensation Committee, the Board approved adjustments to the exercise price of certain outstanding vested and unvested option awards for eligible employees. The exercise price of eligible option awards was reduced to $38.78, which was the closing market price of our Class C capital stock on August 8, 2022. No other changes were made to the terms and conditions of the eligible option awards. We accounted for the reprice of the eligible option awards as an equity modification whereby the incremental fair value attributable to the repriced option awards, as measured on the date of reprice, has been recognized as additional share-based compensation expense. The reprice impacted 7 million stock option awards, affected 3,348 employees and was expected to result in incremental share-based compensation expense of $66 million in total over the remaining requisite service period of the original awards, which was largely through the three months ended September 30, 2024. The weighted-average total fair value of options repriced in August 2022 was $67.58.

Net Income (Loss) Per Share
12 Months Ended
Dec. 31, 2025
Earnings Per Share [Abstract]  
Net Income (Loss) Per Share Net Income (Loss) Per Share
Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares (including Class A common stock, Class B common stock and Class C capital stock) outstanding during the period. In the calculation of basic net income (loss) per share, undistributed earnings are allocated assuming all earnings during the period were distributed.
Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares (including Class A common stock, Class B common stock and Class C capital stock) outstanding during the period and potentially dilutive Class C capital stock equivalents, except in cases where the effect of the Class C capital stock equivalent would be antidilutive. Potentially dilutive Class C capital stock equivalents consist of stock issuable upon exercise of stock options, stock underlying unvested restricted stock units, and stock issuable upon conversion of outstanding Notes.
Class C capital stock issuable upon exercise of stock options and Class C capital stock underlying unvested restricted stock units are calculated using the treasury stock method.
We have applied the if-converted method for calculating any potential dilutive effect of the conversion of the outstanding Notes on diluted net income (loss) per share, as applicable.
For the periods presented, the following table reconciles the denominators used in the basic and diluted net income (loss) per share calculations (in thousands):

For the periods presented, the following Class C capital stock equivalents were excluded from the calculations of diluted net income (loss) per share because their effect would have been antidilutive (in thousands):

In the event of liquidation, dissolution, distribution of assets or winding-up of the Company, the holders of all classes of common and capital stock have equal rights to receive all the assets of the Company after the rights of the holders of preferred stock have been satisfied. We have not presented net income (loss) per share under the two-class method for our Class A
common stock, Class B common stock and Class C capital stock because it would be the same for each class due to equal dividend and liquidation rights for each class.

Commitments and Contingencies Commitments and Contingencies
Interest Rate Lock Commitments
We have entered into IRLCs with prospective borrowers under our mortgage origination operations whereby we commit to lend a certain loan amount under specific terms and at a specific interest rate to the borrower. These commitments are treated as derivatives and are carried at fair value. For additional information regarding our IRLCs, see Note 3 to our consolidated financial statements.
Lease Commitments
We have entered into various non-cancelable operating lease agreements for certain of our office space and equipment with original lease periods expiring between 2026 and 2032. For additional information regarding our lease agreements, see Note 7 to our consolidated financial statements.
Purchase Commitments
Purchase commitments primarily include various non-cancelable agreements to purchase content related to our mobile apps and websites, certain cloud computing services and amounts due under certain partnership agreements. The amounts due for non-cancelable purchase commitments as of December 31, 2025 are as follows (in millions):
2026$135

Escrow Balances
In conducting our title and escrow operations, we routinely hold customers’ assets in escrow, pending completion of real estate transactions, and are responsible for the proper disposition of these balances for our customers. Certain of these amounts are maintained in segregated bank accounts and have not been included in the accompanying consolidated balance sheets. These balances were not material as of December 31, 2025 and 2024.
Surety Bonds
In the course of business, we are required to provide financial commitments in the form of surety bonds to third parties as a guarantee of our performance on and our compliance with certain obligations. If we were to fail to perform or comply with these obligations, any draws upon surety bonds issued on our behalf would then trigger our payment obligation to the surety bond issuer. We have outstanding surety bonds issued for our benefit of approximately $16 million as of December 31, 2025 and 2024.
Legal Proceedings
We are involved in a number of legal proceedings concerning matters arising in connection with the conduct of our business activities, some of which are at preliminary stages and some of which seek an indeterminate amount of damages. We regularly evaluate the status of legal proceedings in which we are involved to assess whether a loss is probable or there is a reasonable possibility that a loss or additional loss may have been incurred to determine if accruals are appropriate. We further evaluate each legal proceeding to assess whether an estimate of possible loss or range of loss can be made if accruals are not appropriate. For certain cases described below, management is unable to provide a meaningful estimate of the possible loss or range of possible loss because, among other reasons, (i) the proceedings are in preliminary stages; (ii) specific damages have not been sought; (iii) damages sought are, in our view, unsupported and/or exaggerated; (iv) there is uncertainty as to the outcome of pending appeals or motions; (v) there are significant factual issues to be resolved; and/or (vi) there are novel legal issues or unsettled legal theories presented. For these cases, however, management does not believe, based on currently available information, that the outcomes of these proceedings will have a material effect on our financial position, results of
operations or cash flow. For the matters discussed below, we have not recorded any material accruals as of December 31, 2025 or 2024.
On September 17, 2019, International Business Machines Corporation (“IBM”) filed a complaint against us in the U.S. District Court for the Central District of California, alleging, among other things, that the Company has infringed and continues to willfully infringe seven patents held by IBM and seeks unspecified damages, including a request that the amount of compensatory damages be trebled, injunctive relief and costs and reasonable attorneys’ fees. Our motion to transfer venue to the U.S. District Court for the Western District of Washington (the “Court”) was granted on May 28, 2020. On November 25, 2022, Zillow filed a motion to join an Inter Partes Review (“IPR”) petition within Ebates Performance Mktg., Inc. d/b/a Rakuten Rewards v. Intl Bus. Machs. Corp. (“Rakuten IPR”), IPR2022-00646 concerning one patent in this action, which the Court granted on April 20, 2023. On October 11, 2023, the U.S. Patent and Trial Appeal Board (“PTAB”) ruled on the Rakuten IPR finding the claims of the patent asserted against Zillow unpatentable. IBM appealed the PTAB’s decision on November 21, 2023 (the “PTAB Appeal”), and cross appeals were filed by Ebates Performance Marketing Inc. on November 21, 2023 and by us on December 15, 2023. On March 20, 2024, IBM voluntarily dismissed all claims filed in this action against Zillow with prejudice, with the exception of those pertaining to the patent asserted within the pending PTAB Appeal. On June 21, 2024 we filed our response to the PTAB Appeal. On July 30, 2024, IBM filed its reply in further support of the PTAB Appeal. On September 3, 2024, we filed our reply in further support of our cross-appeal. On December 9, 2025, the Federal Circuit issued an order affirming the October 11, 2023 PTAB decision in full. There is a reasonable possibility that a loss may be incurred related to this matter; however, the possible loss or range of loss is not estimable. We deny the allegations of any wrongdoing and intend to vigorously defend the claims in the lawsuit.
On November 16, 2021, November 19, 2021 and January 6, 2022, three purported class action lawsuits were filed against us and certain of our executive officers, alleging, among other things, violations of federal securities laws on behalf of a class of those who purchased our stock between August 7, 2020 and November 2, 2021. The three purported class action lawsuits, captioned Barua v. Zillow Group, Inc. et al., Silverberg v. Zillow Group, et al. and Hillier v. Zillow Group, Inc. et al. were brought in the Court and were consolidated on February 16, 2022 (the “Federal Securities Suit”). On May 12, 2022, the plaintiffs filed their amended consolidated complaint which alleges, among other things, that we issued materially false and misleading statements regarding our Zillow Offers business. The complaints seek to recover, among other things, alleged damages sustained by the purported class members as a result of the alleged misconduct. On December 7, 2022, the Court rendered its decision granting our previously filed motion to dismiss, in part, and denying the motion, in part. On January 23, 2023, we filed our answer to the consolidated complaint. On March 14, 2024, plaintiffs filed a motion for class certification, which was granted on August 23, 2024. On September 6, 2024, we filed a petition for permission to appeal the class certification order, on September 16, 2024, plaintiffs filed their opposition to our petition, and on September 23, 2024, we filed our reply in further support of the petition. On October 24, 2024, the Ninth Circuit issued an order granting Zillow permission to appeal. On November 1, 2024, the Court issued an order staying the Federal Securities Suit pending the outcome of the appeal, which was extended on October 10, 2025. On January 8, 2025, we filed our opening brief in the appeal. On March 10, 2025, plaintiffs filed their response brief, and on April 30, 2025, we filed our reply brief. On September 26, 2025, the Ninth Circuit affirmed the Court’s class certification. On October 24, 2025, we filed an en banc petition before the Ninth Circuit seeking rehearing of the Ninth Circuit’s September 26 decision. On January 6, 2026, the Ninth Circuit issued an order denying Zillow’s en banc petition. There is a reasonable possibility that a loss may be incurred related to this matter; however, the possible loss or range of loss is not estimable. We deny the allegations of any wrongdoing and intend to vigorously defend the claims in this consolidated lawsuit.
On March 10, 2022, May 5, 2022, July 20, 2022 and October 31, 2024, shareholder derivative suits were filed in the Court and on July 25, 2022, a shareholder derivative suit was filed in the Superior Court of the State of Washington, King County, against us and certain of our executive officers and directors seeking unspecified damages on behalf of the Company and certain other relief, such as reform to corporate governance practices. The plaintiffs (including the Company as a nominal defendant) allege, among other things, that the defendants breached their fiduciary duties by failing to maintain an effective system of internal controls, which purportedly caused the losses the Company incurred when it decided to wind down Zillow Offers operations. Plaintiffs also allege, among other things, violations of Section 14(a) and Section 20(a) of the Exchange Act, insider trading and waste of corporate assets. On August 23, 2023, a second shareholder derivative suit was filed in the Superior Court of the State of Washington, King County. These shareholder derivative lawsuits have since been stayed by the relevant courts and they remain stayed as of December 31, 2025. There is a reasonable possibility that a loss may be incurred related to this matter; however, the possible loss or range of loss is not estimable. The defendants deny the allegations of any wrongdoing and vigorously defend the claims in these lawsuits.
On September 30, 2025, the Federal Trade Commission filed a complaint in the U.S. District Court for the Eastern District of Virginia against Zillow Group, Inc., Zillow, Inc., and Redfin Corporation. On October 1, 2025, the Attorneys General of the Commonwealth of Virginia and the States of Arizona, Connecticut, New York, and Washington filed a similar complaint
against the same parties in the same court. The complaints allege that the partnership entered into between Zillow and Redfin on February 6, 2025, harmed competition for online multifamily rental-listings in violation of federal antitrust laws. The plaintiffs seek injunctive and other equitable relief. We filed our motion to dismiss on January 13, 2026. Plaintiffs filed their opposition to our motion to dismiss on February 3, 2026. We deny the allegations of any wrongdoing and intend to vigorously defend the claims in these lawsuits.
In addition to the matters discussed above, from time to time, we are involved in litigation and claims that arise in the ordinary course of business. Although we cannot be certain of the outcome of any such litigation or claims, nor the amount of damages and exposure that we could incur, we currently believe that the final disposition of such matters will not have a material effect on our business, financial position, results of operations or cash flow. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.
Indemnifications
In the ordinary course of business, we enter into contractual arrangements under which we agree to provide indemnification of varying scope and terms to business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of the breach of such agreements and out of intellectual property infringement claims made by third parties. In addition, we have agreements that indemnify certain issuers of surety bonds against losses that they may incur as a result of executing surety bonds on our behalf. For our indemnification arrangements, payment may be conditional on the other party making a claim pursuant to the procedures specified in the particular contract. Further, our obligations under these agreements may be limited in terms of time and/or amount, and in some instances, we may have recourse against third parties for certain payments. In addition, we have indemnification agreements with certain of our directors and executive officers that require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. The terms of such obligations may vary.

Segment Reporting [Abstract]  
Segment Information Segment Information
Our CODM is our CEO who manages our business, makes operating decisions and evaluates operating performance on the basis of the company as a whole. This aligns to our ongoing growth strategy and our intent to provide integrated customer solutions for all tasks and services related to facilitating real estate transactions. Accordingly, we have a single operating and reportable segment.
Our CODM assesses performance and decides how to allocate resources based on net income (loss) as reported in our consolidated statements of operations. The measure of segment assets is reported on the consolidated balance sheets as total assets. The CODM uses net income (loss) to evaluate return on total assets in deciding whether to invest in the development and expansion of our consolidated operations or into strategic transactions, such as acquisitions and capital repurchases. Net income (loss) is also used to monitor budget versus actual results, perform competitive benchmarking analyses, and is considered in evaluating our executives’ compensation.

Subsequent Event
On January 30, 2026, Zillow Group entered into a $500 million Revolving Credit Facility by and among Zillow Group, MFTB Holdco, Inc., Zillow, Inc. (the “Borrower”), the lenders from time to time party thereto, Goldman Sachs Bank USA as administrative agent and as issuing bank, and other issuing banks from time to time party thereto. The Revolving Credit Facility may be increased by an additional $250 million subject to the terms of the credit agreement. Revolving loans on the Revolving Credit Facility bear interest at a floating rate based on either an alternative base rate, as defined in the credit agreement, plus an applicable margin or SOFR plus an applicable margin, depending on Zillow Group’s total net leverage ratio. Revolving loans may be borrowed, repaid and reborrowed under the Revolving Credit Facility until January 30, 2031, at which time all amounts borrowed must be repaid. Revolving loans may be prepaid, and revolving loan commitments may be permanently reduced by the Borrower in whole or in part, without penalty or premium.
The Revolving Credit Facility contains customary representations, warranties and affirmative and negative covenants, including a total net leverage ratio financial covenant. The negative covenants include restrictions on the incurrence of liens and indebtedness, certain investments and acquisitions, dividends, stock repurchases, transactions with affiliates and other matters, all subject to certain exceptions. The Borrower’s obligations under the Revolving Credit Facility are guaranteed by Zillow Group, MFTB Holdco, Inc. and certain of the Borrower’s subsidiaries. The Borrower’s obligations under the Revolving Credit
Facility are secured by a first priority security interest in substantially all of the assets of the Borrower and such guarantors, subject to customary exclusions.
We have not drawn any amounts under the Revolving Credit Facility as of the date of this Annual Report on Form 10-K. Borrowings on the Revolving Credit Facility will be classified within long-term liabilities in our consolidated balance sheets.

On November 19, 2025, Jeremy Hofmann, Chief Financial Officer of the Company, entered into a 10b5-1 sales plan intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Exchange Act. This 10b5-1 sales plan provides for (1) the sale of up to 100,000 shares of Class C capital stock related to the exercise of option awards granted to Mr. Hofmann and (2) the sale of an indeterminate number of shares of Class C capital stock related to the vesting of restricted stock units granted to Mr. Hofmann. The number of shares of Class C capital stock that will be sold under this 10b5-1 sales plan related to vesting of restricted stock unit awards is not yet determinable because (i) certain future awards granted during the life of the plan that follow the same vesting schedule as existing awards under the plan may be covered by the terms of the plan and (ii) for each vested restricted stock unit award that is covered by the terms of the plan, an unknown number of shares will be sold to satisfy tax withholding prior to any sale occurring under the terms of the plan. This 10b5-1 sales plan will become effective on February 17, 2026 and will terminate on February 16, 2027, subject to earlier termination as provided in the plan.

Risk Management, Strategy and Management Oversight

We have an enterprise risk management function responsible for the oversight and assessment of ongoing and emerging risks to our business operations and the integrity of our data, including the impact of cybersecurity risks. Our enterprise risk management team maintains a steering committee that oversees and opines on our processes to identify, prioritize and assess key risks, including risks related to cybersecurity. The steering committee is composed of senior leaders with visibility into our key risks. These members have expertise in the areas of risk management, business strategy, information technology, cybersecurity, legal and compliance, finance, and business products, among others. In partnership with other stakeholders, this steering committee monitors risk exposures, promotes risk-management strategies, and implements acceptance and notification criteria. The activities of the steering committee are overseen by the Audit Committee of our Board (the “Audit Committee”).

We also maintain an information security function that oversees the protection of our information assets through a program informed by standards promoted by the National Institute of Standards and Technology cybersecurity framework and the Cyber Risk Institute’s Cyber Profile. These frameworks guide our information security function in designing programs to assess cybersecurity risks and respond to cybersecurity incidents. The information security team is led by a designated Chief Information Security Officer (“CISO”) who is responsible for leading enterprise-wide cybersecurity strategy, including assessing and managing risks from cybersecurity threats, and implementing technical security controls by maintaining policies, standards and processes. With more than 20 years of experience in the field of technology and cybersecurity, our CISO has had extensive involvement with the information security function and the maintenance of a robust cybersecurity program. Our CISO has held data privacy and information security roles with increasing responsibility in heavily regulated industries such as financial services, technology and gaming and is a certified information systems security professional.

The information security team maintains incident response policies and procedures designed to help protect the integrity, availability and confidentiality of information and help prevent loss of service. Additionally, we conduct an annual cybersecurity awareness training to educate our employees and empower them to help prevent and respond to cybersecurity events and incidents. Cybersecurity events and incidents may be reported or detected through a variety of means, including emails to centralized information security addresses, our online information technology ticketing system, automatic alerts and incident detection systems, direct discovery by our information security team, or reports from employees or other third parties. Additionally, our incident response policies and procedures specify the process for initial investigation and containment procedures, remediation tactics, retention of documentation and internal and external communications. Our incident response policies and procedures also specify processes for analyzing the severity of an identified incident. In response to cybersecurity incidents, we may involve external advisors to assist with remediation efforts and communications and we may seek to mitigate associated liabilities through our insurance coverage. Such third parties may include external legal counsel, forensic investigators and public relation firms, among others. These vendors serve to support our existing processes and procedures and operate as an extension of our enterprise risk management and information security functions.

Our internal audit team conducts security controls testing over systems in scope for various regulatory and compliance requirements. In addition, management performs periodic third-party risk assessments, vulnerability testing, and system and
cloud security assessments against our information technology environment. Management also engages third-party external auditors to perform independent testing against all systems in scope for our regulatory and customer-driven compliance obligations.

We engage a variety of third-party service providers to process and store data, including certain customer information, some of which may include personally identifiable information. We also depend on third-party service providers to host many of the systems and infrastructure used to provide our products and services. A limited number of third-party services support essential functions of our business, including the use of cloud-based technology. We rely on these third parties to implement their own cybersecurity programs and cannot ensure their effectiveness. To manage cybersecurity risks arising from our use of third parties, we have a third-party service provider management program which includes the use of security questionnaires, review of statements of work and related information security addenda, procuring results of audits and compliance reviews and obtaining overviews of network infrastructure, among others. Depending on the nature of the services provided, the sensitivity of the data at issue and the identity of the third-party, our third-party service provider management process may involve different levels of assessment designed to help identify cybersecurity risks associated with a provider and impose contractual obligations related to cybersecurity on the provider.

Summary of Significant Accounting Policies (Policies)
12 Months Ended
Dec. 31, 2025
Accounting Policies [Abstract]  
Basis of Presentation
Basis of Presentation
The accompanying consolidated financial statements include Zillow Group, Inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These consolidated financial statements have been prepared in conformity with GAAP.
Use of Estimates
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. On an ongoing basis, we evaluate our estimates, including those related to the accounting for certain revenue offerings, amortization period and recoverability of contract cost assets, website and software development costs, recoverability of long-lived assets and intangible assets, share-based compensation, income taxes, business combinations, including the initial and subsequent fair value measurements of assets (primarily intangible assets), liabilities and contingent consideration, and the recoverability of goodwill, among others. To the extent there are material differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected. The health of the housing market and the broader economy may result in additional uncertainty with respect to estimates, judgments and assumptions, which may materially impact the estimates previously listed, among others.
Concentrations of Credit Risk
Concentrations of Credit Risk
Financial instruments, which potentially subject us to concentrations of credit risk, consist primarily of cash and cash equivalents, investments, accounts receivable and mortgage loans held for sale. We place cash and cash equivalents and investments with major financial institutions, which management assesses to be of high credit quality, to limit the exposure of our investments to credit risk.
Credit risk with respect to accounts receivable is dispersed due to the large number of customers. There were no customers that comprised 10% or more of our total accounts receivable as of December 31, 2025 or 2024. Further, our credit risk on accounts receivable is mitigated by the relatively short payment terms that we offer. Collateral is not required for accounts receivable. We maintain an allowance for doubtful accounts such that receivables are stated at net realizable value.
Similarly, our credit risk on mortgage loans held for sale is dispersed due to a large number of customers and is mitigated by the fact that we typically sell mortgages on the secondary market within a relatively short period of time after the loan is originated.
Cash and Cash Equivalents/Restricted Cash
Cash and Cash Equivalents
Cash includes demand deposits with banks or financial institutions. Cash equivalents include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Our cash equivalents represent investments with original maturities of three months or less. We regularly maintain cash in excess of federally insured limits at financial institutions.
Restricted Cash
Restricted cash primarily consists of amounts used to fund customer home purchases in our mortgage origination operations.
Short-term Investments
Short-term Investments
Our investments consist of fixed income securities, which include U.S. government treasury securities, investment grade corporate securities, U.S. government agency securities, and commercial paper. The investments are available to support current operations and are classified as short-term investments measured at fair value. Our investment policy only allows for purchases of investment-grade securities and provides guidelines on concentrations to ensure minimum risk of loss. We evaluate whether unrealized losses on available-for-sale debt securities are the result of credit worthiness of the securities held
or other non-credit related factors. If an unrealized loss is the result of credit quality factors, we recognize an allowance reflective of our current estimate of credit losses expected to be incurred over the life of the financial instrument on a specific identification basis upon initial recognition and at each reporting period. If a reduction in value is a result of other factors, we continue to classify the losses in comprehensive loss unless either we intend to sell the security or it is more likely than not we will be required to sell the security. We did not identify any unrealized loss positions in our available-for-sale securities that were the result of credit losses as of December 31, 2025 or 2024. Additionally, we have the ability to hold our investments to maturity and more likely than not will not be required to sell the securities before a recovery of the amortized cost basis has occurred.
Mortgage Loans Held for Sale
Mortgage Loans Held for Sale
Mortgage loans held for sale include residential mortgages originated for sale in the secondary market in connection with our mortgage origination operations. We have elected the fair value option for all mortgage loans held for sale as election of this option allows for a better offset of the changes in fair values of the loans and the derivative instruments used to economically hedge them without having to apply complex hedge accounting provisions. Mortgage loans held for sale are initially recorded at fair value based on either sale commitments or current market quotes and are adjusted for subsequent changes in fair value until the loans are sold. Net origination costs and fees associated with mortgage loans are recognized as incurred. We sell substantially all of the mortgages we originate and the related servicing rights to third-party purchasers. Interest income is earned from the date a mortgage loan is originated until the loan is sold and is classified within other income, net in the consolidated statements of operations.
Generally, mortgage loans originated are sold within a short period of time in the secondary mortgage market on a servicing released, nonrecourse basis, which limits exposure to nonperformance by loan buyer counterparties. However, we remain liable for certain limited representations and warranties related to loan sales, such as non-compliance with defined loan origination or documentation standards, including misstatement in the loan documents, early payoff or default on early payments. Mortgage investors could seek to have us buy back loans or compensate them for losses incurred on mortgages we have sold based on claims that we breached our limited representations and warranties. We record a reserve for probable losses in connection with the sale of mortgage loans within accrued expenses and other current liabilities in the consolidated balance sheet.
Loan Commitments and Related Derivatives
Loan Commitments and Related Derivatives
We are party to IRLCs, which are extended to borrowers who have applied for loan funding and meet defined credit and underwriting criteria in connection with our mortgage origination operations. IRLCs are accounted for as derivative instruments recorded at fair value with gains and losses recognized in revenue in the consolidated statements of operations. We manage our interest rate risk related to IRLCs and mortgage loans held for sale through the use of derivative instruments, generally forward contracts on MBSs, which are commitments to either purchase or sell a financial instrument at a future date for a specified price, and mandatory loan commitments, which are an obligation by an investor to buy loans at a specified price within a specified time period. We do not enter into or hold derivatives for trading or speculative purposes, and our derivatives are not designated as hedging instruments. Changes in the fair value of our derivative financial instruments are recognized in revenue in our consolidated statements of operations, and the fair values are reflected in other current assets or other current liabilities, as applicable. Refer to Note 3 to our consolidated financial statements for additional information regarding IRLCs and related derivatives.
There are no material credit-risk-related contingent features within our derivative agreements, and counterparty risk is considered minimal. Gains and losses on IRLCs are substantially offset by corresponding gains or losses on forward contracts on MBSs and mandatory loan commitments. We are generally not exposed to variability in cash flows of derivative instruments for more than approximately 90 days.
Contract Balances/Contract Cost Assets/Revenue Recognition
Contract Balances
Accounts receivable represent our unconditional right to consideration. Accounts receivable are generally due within 30 days and are recorded net of the allowance for doubtful accounts. The allowance for doubtful accounts represents our estimate of expected credit losses over the contractual life of the accounts receivable. To evaluate the adequacy of our allowance for doubtful accounts each reporting period, we analyze the accounts receivable balances with similar risk characteristics on a
collective basis, considering factors such as the aging of receivable balances, payment terms, historical loss experience, current information and future expectations. Changes to the allowance for doubtful accounts are adjusted through credit loss expense, which is included in general and administrative expenses in the consolidated statements of operations.
Contract assets represent our right to consideration in exchange for goods and services that we have transferred to the customer when that right is conditional on something other than the passage of time. Contract assets are primarily related to our Zillow Preferred (formerly “Flex”), Pay-Per-Lease and StreetEasy Experts offerings, whereby we estimate variable consideration based on the expected number of real estate transactions to be closed for Zillow Preferred and StreetEasy Experts, and qualified leases to be secured for Pay-Per-Lease. We recognize revenue when we satisfy our performance obligations under the corresponding contracts. The current portion of contract assets are recorded within prepaid expenses and other current assets and the long-term portion of contract assets are recorded within other assets in our consolidated balance sheets.
Contract liabilities consist of deferred revenue, which relates to payments received in advance of performance under a revenue contract. Deferred revenue is primarily related to prepaid advertising fees received or billed in advance of satisfying our performance obligations and prepaid but unrecognized subscription revenue. Deferred revenue is recognized when or as we satisfy our obligations under contracts with customers.
Contract Cost Assets
We capitalize certain incremental costs of obtaining contracts with customers which we expect to recover. These costs relate to commissions paid to sales personnel, primarily for our Premier Agent and Rentals products. As a practical expedient, we recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that we otherwise would have recognized is one year or less. Capitalized commission costs are recorded as contract cost assets in our consolidated balance sheets. Contract cost assets are amortized to expense on a straight-line basis over a period that is consistent with the transfer to the customer of the products or services to which the asset relates, generally the estimated life of the customer relationship. Amortization expense related to contract cost assets is included in sales and marketing expenses in our consolidated statements of operations. In determining the estimated life of our customer relationships, we consider quantitative and qualitative data, including, but not limited to, historical customer data, recent changes or expected changes in product or service offerings and changes in how we monetize our products and services.
We monitor our contract cost assets for impairment and recognize an impairment loss in the consolidated statements of operations to the extent the carrying amount of the asset recognized exceeds the amount of consideration that we expect to receive in the future and that we have received but have not recognized in revenue less the costs that relate directly to providing those goods or services that have not yet been recognized as expenses. For the years ended December 31, 2025, 2024 and 2023, we did not record any material impairment losses to our contract cost assets.
Revenue Recognition
We recognize revenue when or as we satisfy our performance obligations by transferring control of the promised products or services to our customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those products or services.
As a practical expedient, we do not adjust the promised amount of consideration for the effects of a significant financing component, as the period between our transfer of a promised product or service to a customer and when the customer pays for that product or service is generally one year or less, with the exception of certain of our pay for performance products, including Zillow Preferred and StreetEasy Experts, whereby we may not receive payment for more than a year after control of the promised products or services is transferred to our customers. In these cases, however, because a substantial portion of the consideration is variable, we have concluded the contracts do not include a significant financing component.
We do not disclose the transaction price related to remaining performance obligations for (i) contracts with an original expected duration of one year or less or (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for performance completed to date. The remaining duration over which we satisfy our performance obligations is generally less than one year.
Our revenue is classified into four categories: Residential, Mortgages, Rentals and Other. Our “For Sale revenue” subtotal includes our Residential and Mortgages revenue categories and represents our revenue from participation in residential real estate purchase and sale transactions.
Residential. Residential revenue includes revenue generated from our agent and software offerings and revenue derived from our New Construction marketplace and StreetEasy for sale product offerings. Agent offerings include Premier Agent market-based pricing, Zillow Preferred (formerly Flex) and Zillow Showcase. Software offerings primarily include Follow Up Boss, dotloop, and ShowingTime.
Premier Agent advertising products, which include the delivery of validated customer connections, or leads, are offered on a share of voice (“market-based pricing”) and pay for performance (“Zillow Preferred”) basis. Connections are delivered when consumer contact information is provided to Premier Agent partners. We do not promise any minimum or maximum number of connections to customers for either market-based pricing or Zillow Preferred.
For Premier Agent market-based pricing, we control when and how many connections to deliver based on a customer’s share of voice. A Premier Agent partner’s share of voice in a zip code is determined by their proportional monthly prepaid spend in that zip code as a percentage of the total monthly prepaid spend of all Premier Agent partners in that zip code, and determines the proportion of connections a Premier Agent partner receives. The number of connections delivered for a given spend level is dynamic; as demand for advertising in a zip code increases or decreases, the number of connections delivered to a Premier Agent partner in that zip code decreases or increases accordingly.
We recognize revenue related to Premier Agent market-based pricing products and services based on the monthly prepaid spend recognized on a straight-line basis during the monthly billing period over which the products and services are provided. This methodology best depicts how we satisfy our performance obligations to customers, as we continuously transfer control of the performance obligations to the customer over time. We have not allocated the transaction price to each performance obligation within our Premier Agent market-based pricing arrangements, as the amounts recognized would be the same irrespective of any allocation.
Our pay for performance pricing model, “Zillow Preferred,” was introduced as the next chapter for our Flex program in the fourth quarter of 2025, and is available in certain markets to select partners. With the Zillow Preferred model, Premier Agent partners are provided with leads and pay a performance advertising fee when a real estate transaction is closed with one of the leads, generally within two years. With this pricing model, the transaction price represents variable consideration, as the amount to which we expect to be entitled varies based on the number of leads that convert into real estate transactions and the value of those transactions. We estimate variable consideration and record revenue over time as our performance obligations, or leads, are transferred. We do not believe that a significant reversal in the amount of cumulative revenue recognized will occur once the uncertainty related to the number of transactions closed is subsequently resolved. We record a contract asset for our estimate of the consideration to which we will be entitled when the right to the consideration is conditional. When the right to consideration becomes unconditional, upon the close of a real estate transaction, we reclassify amounts to accounts receivable.
Zillow Showcase is an advertising and marketing solution which allows real estate agents to advertise an enhanced listing on our mobile apps and websites. Customers pay for Zillow Showcase credits upfront, and each credit allows the customer to apply the Showcase listing treatment to one active for-sale listing. Zillow Showcase revenue is recognized by measuring our progress towards satisfaction of our performance obligations, primarily the enhanced listing features, using the output method of results achieved.
Follow Up Boss is a SaaS solution allowing real estate agents, teams and brokerages to manage real estate leads from the initial contact through the home buying or selling process. Follow Up Boss revenue is primarily billed in advance on a monthly basis and recognized ratably over the contract period, aligning to the satisfaction of our performance obligations.
Dotloop is a real estate transaction management SaaS solution. ShowingTime primarily generates revenue through Appointment Center, which is a SaaS and call center solution allowing real estate agents, brokerages and multiple listing services to efficiently schedule real estate viewing appointments on behalf of their customers. Both dotloop and Appointment Center revenue are primarily billed monthly in advance and recognized ratably over the contract period, aligning to the satisfaction of our performance obligations.
Our new construction marketing solutions allow home builders to showcase their available inventory to home shoppers. New construction revenue primarily includes revenue generated by advertising sold to builders on a cost per residential community basis whereby we recognize revenue on a straight-line basis during the contractual period over which the communities are advertised on our mobile apps and websites. New construction revenue also includes revenue generated on a cost per impression basis whereby we recognize revenue as impressions are delivered to users interacting with our mobile apps and websites, which is the amount for which we have the right to invoice. Consideration for new construction products is billed in arrears.
StreetEasy for-sale revenue primarily consists of our StreetEasy Experts and StreetEasy subscription offerings. StreetEasy Experts is our pay for performance pricing model available in the New York City market for which agents and brokers are provided with leads at no initial cost and pay a performance referral fee only when a real estate purchase transaction is closed with one of the leads. Under the StreetEasy Experts pricing model, the transaction price represents variable consideration, as the amount to which we expect to be entitled varies based on the number of leads that convert into real estate transactions and the value of those transactions. We estimate variable consideration based on the expected number of closed transactions during the period. We do not believe that a significant reversal in the amount of cumulative revenue recognized will occur when the uncertainty related to the number of transactions closed is subsequently resolved. We record a corresponding contract asset for the estimate of variable consideration for StreetEasy Experts when the right to the consideration is conditional. When the right to consideration becomes unconditional upon the close of a real estate transaction, we reclassify amounts to accounts receivable. Revenue generated through StreetEasy subscription offerings includes the sale of advertising and a suite of tools to developers, property managers, agents and other real estate professionals. StreetEasy subscription customers pay in advance on a cost per property basis. We recognize revenue for our StreetEasy subscription offerings on a straight-line basis over the contractual listing period which aligns to our satisfaction of performance obligations.
Rentals. Rentals revenue includes the sale of advertising and a suite of tools to rental professionals, landlords and other market participants under the Zillow and StreetEasy brands. Rentals revenue includes revenue generated by advertising sold to property managers, landlords and other rental professionals on a cost per lease, listing or impression basis or for a fixed fee for certain advertising packages. We recognize revenue as leads or impressions are provided to rental professionals, or as rental listings are published on our mobile apps and websites, which is the amount for which we have the right to invoice. We bill our fixed fee rentals products monthly in arrears and recognize revenue ratably over the contract period, aligning to the satisfaction of our performance obligations. The number of leases generated through our rentals Pay-Per-Lease product during the period is accounted for as variable consideration. We estimate the amount of consideration based on the expected number of qualified leases secured during the period. We do not believe that a significant reversal in the amount of cumulative revenue recognized will occur once the uncertainty related to the number of leases secured is subsequently resolved. We record a contract asset for the estimate of variable consideration for Pay-Per-Lease when the right to the consideration is conditional. When the right to consideration becomes unconditional upon the execution of a lease, we reclassify amounts to accounts receivable. Rentals revenue also includes revenue generated from our rental applications product, through which potential renters can submit applications to multiple properties for a flat service fee. Rental applications customers pay upfront and we recognize revenue ratably over the contractual period during which the customer has the right to access and submit the rental application.
Mortgages. Mortgages revenue primarily includes revenue generated by Zillow Home Loans, our affiliated mortgage lender, and marketing products sold to mortgage professionals on a cost per lead basis, primarily our Connect services.
Mortgage origination revenue reflects origination fees on purchase or refinance mortgages and the corresponding sale, or expected future sale, of a loan. When an IRLC is made to a customer, we record the expected gain on sale of the mortgage, plus the estimated earnings from the expected sale of the associated servicing rights, adjusted for a pull-through percentage (which is defined as the likelihood that an IRLC will be originated), as revenue. Revenue from loan origination fees is recognized at the time the related purchase or refinance transactions are completed, usually upon the close of escrow and when we fund the purchase or refinance mortgage loans. Once funded, mortgage loans held for sale are recorded at fair value based on either sale commitments or current market quotes and are adjusted for subsequent changes in fair value until the loan is sold. Origination costs associated with originating mortgage loans are recognized as incurred. We generally sell the mortgages we originate and the related servicing rights to third-party purchasers.
Mortgage loans are sold with limited recourse provisions, which can result in repurchases of loans previously sold to investors or payments to reimburse investors for loan losses. Based on historical experience, discussions with our mortgage purchasers, analysis of the volume of mortgages we originated and current housing and credit market conditions, we estimate and record a loss reserve for mortgage loans held for sale, as well as known and projected mortgage loan repurchase requests. These have historically not been material to our financial statements.
Zillow Group operates Connect through its wholly owned subsidiary, Zillow Group Marketplace, Inc., a licensed mortgage broker. For our Connect cost per lead marketing product, participating qualified mortgage professionals typically make a prepayment to gain access to consumers interested in connecting with mortgage professionals. Mortgage professionals who exhaust their initial prepayment prepay additional funds to continue to participate in the marketplace. We recognize revenue when a user contacts a mortgage professional through our mortgages platform, which corresponds directly to the value of our performance.
Other. Other revenue primarily includes revenue generated from display products, which consist of graphical mobile and web advertising sold on a cost per thousand impressions or cost per click basis to advertisers promoting their brands on our mobile apps and websites. We recognize revenue as clicks occur or as impressions are delivered to users interacting with our mobile apps or websites, which is the amount for which we have the right to invoice.
There were no customers that generated 10% or more of our total revenue in the years ended December 31, 2025, 2024 or 2023.
Cost of Revenue. Cost of revenue consists of expenses related to operating our mobile apps and websites, including associated headcount-related expenses, such as salaries, benefits, bonuses and share-based compensation expense, as well as revenue-sharing costs related to our commercial business relationships, depreciation expense, and costs associated with hosting our mobile apps and websites. Cost of revenue also includes amortization costs related to capitalized website and development activities, amortization of software, amortization of certain intangible assets and other costs to obtain data used to populate our mobile apps and websites, and amortization of certain intangible assets recorded in connection with acquisitions, including developed technology. Cost of revenue also includes credit card fees and ad serving costs paid to third parties, direct costs to provide our rental applications product, and direct costs to originate mortgage loans, including underwriting and processing costs.
Sales and Marketing. Sales and marketing expenses consist of advertising costs and other sales expenses related to promotional and marketing activities, headcount-related expenses, including salaries, commissions, benefits, bonuses and share-based compensation expense for sales, sales support, customer support, including the customer connections team and mortgage loan officers and specialists, marketing and public relations employees, depreciation expense and amortization of certain intangible assets recorded in connection with acquisitions and strategic partnerships, including trade names and trademarks and customer relationships.
Advertising costs are expensed as incurred.
Property and Equipment
Property and Equipment
Property and equipment is recorded at cost and depreciated using the straight-line method over the estimated useful lives of the related assets. The useful lives are as follows:
 
Computer equipment  
3 years
Office equipment, furniture and fixtures  
5 to 7 years
Leasehold improvements  Shorter of expected useful life or lease term
Maintenance and repair costs are expensed as incurred. Major improvements, which extend the useful life of the related asset, are capitalized. Upon disposal of a fixed asset, we record a gain or loss based on the difference between the proceeds received and the net book value of the disposed asset. We remove fully depreciated property and equipment from the cost and accumulated depreciation amounts disclosed.
Website and Internal-Use Software Development Costs
Website and Software Development Costs
Costs incurred in the preliminary stages of website and software development are expensed as incurred. Once an application has reached the development stage, internal and external costs, if direct and incremental and deemed by management to be significant, are capitalized in property and equipment and amortized on a straight-line basis over their estimated useful lives. Maintenance and enhancement costs, including those costs in the post-implementation stages, are typically expensed as incurred, unless such costs relate to substantial upgrades and enhancements to the website or software that result in added functionality, in which case the costs are capitalized and amortized on a straight-line basis over their estimated
useful lives. Amortization expense related to capitalized website and software development costs is included in cost of revenue in our consolidated statements of operations.
Capitalized development activities placed in service are amortized over the expected useful lives of those releases, currently estimated at three to five years. The estimated useful lives of website and software development activities are reviewed frequently and adjusted as appropriate to reflect upcoming development activities that may include significant upgrades and/or enhancements to the existing functionality. We remove fully amortized website and software development costs from the cost and accumulated amortization amounts disclosed.
Construction-in-progress primarily consists of website and software development costs that are capitalizable, but for which the associated applications have not been placed in service.
Leases
Leases
Our lease portfolio is primarily composed of operating leases for our office space. We determine whether a contract is or contains a lease at inception of the contract. Our operating leases are included in right of use assets and lease liabilities in our consolidated balance sheets. We do not have any material financing leases.
Right of use assets represent our right to use an underlying asset during the lease term and lease liabilities represent our obligation to make lease payments. Right of use assets and lease liabilities are recognized at the lease commencement date based on the present value of the total lease payments contracted but not yet paid, including lease incentives not yet received, with the right of use assets further adjusted for any prepaid or accrued lease payments, lease incentives received and/or initial direct costs incurred.
We have lease agreements that include both lease components (e.g., fixed rent) and non-lease components (e.g., common area maintenance). For such leases, we account for the lease and non-lease components as a single component. Certain lease arrangements also include variable payments for costs such as common-area maintenance, utilities, taxes or other operating costs, which are based on a percentage of actual expenses incurred or a fluctuating rate which is unknown at the inception of the contract. These variable lease payments are excluded from the measurement of the right of use assets and lease liabilities.
Our leases have remaining lease terms ranging from approximately four years to seven years, most of which include one or more options to extend the lease term. The renewal options can generally extend the lease term for up to an additional one to five years. When determining if a renewal option is reasonably certain of being exercised at lease commencement, we consider several factors, including but not limited to, contract-based, asset-based and entity-based factors. We reassess the term of existing leases if there is a significant event or change in circumstances within our control that affects whether we are reasonably certain to exercise an option to extend a lease. Examples of such events or changes include construction of significant leasehold improvements or other modifications or customizations to the underlying asset, relevant business decisions or subleases. As of December 31, 2025, we have concluded that our renewal options are not reasonably certain of being exercised, therefore, renewal options are not included in the right of use assets and lease liabilities.
As our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. We apply a portfolio approach for determining the incremental borrowing rate based on the applicable lease terms and the current economic environment.
We recognize lease expense for operating leases on a straight-line basis over the lease term. Variable lease payments are generally recognized when incurred. For leases with an initial term of 12 months or less, we recognize the associated lease payments in the consolidated statements of operations on a straight-line basis over the lease term. These expenses are included in general and administrative expenses in the consolidated statements of operations.
Recoverability of Goodwill
Recoverability of Goodwill
Goodwill is measured as the excess of consideration transferred for an acquired business over the net of the acquisition date fair values of the assets acquired and the liabilities assumed, and is not amortized. We assess the impairment of goodwill at the reporting unit level on an annual basis, in our fourth quarter, or whenever events or changes in circumstances indicate that goodwill may be impaired. In our evaluation of goodwill, we initially perform a qualitative assessment to determine whether the existence of events or circumstances indicates that it is more likely than not that the carrying value of each reporting unit is greater than its fair value. If it is more likely than not that the carrying value of a reporting unit is greater than its fair value, we perform a quantitative assessment and an impairment charge is recorded in our statements of operations if the carrying value of the reporting unit exceeds its fair value. During the years ended December 31, 2025, 2024 and 2023, we did not record any impairments related to goodwill.
Our chief operating decision maker (“CODM”) is our chief executive officer (“CEO”) who manages our business, makes operating decisions and evaluates operating performance on the basis of the company as a whole. This aligns to our ongoing growth strategy and our intent to provide integrated customer solutions for all tasks and services related to facilitating real estate transactions. Accordingly, we have a single operating and reportable segment.
Intangible Assets/Recoverability of Intangible Assets with Definite Lives and Other Long-Lived Assets
Intangible Assets
We purchase and license data content from multiple data providers. In some instances, we retain perpetual rights to this information after our contract with a vendor ends; in other instances, the information and data are licensed only during the fixed term of the agreement.
We capitalize payments made to third parties for data licenses that we expect to recover through generation of revenue and margins. We amortize capitalized purchased content on a straight-line basis using our best estimate of the useful life of the asset, which ranges from three to seven years. Under certain other data agreements, the underlying data is obtained on a subscription basis with consistent monthly or quarterly recurring payment terms over the contractual period. Upon the expiration of such arrangements, we no longer have the right to access the related data, and therefore, the costs incurred under such contracts are not capitalized and are expensed as payments are made.
We also capitalize costs related to the license of certain internal-use software from third parties, including certain licenses of software in cloud computing arrangements. Additionally, we capitalize costs incurred during the application development stage related to the development and customization of internal-use software and enterprise cloud computing services. We expense costs as incurred related to the planning and post-implementation phases of development. Capitalized internal-use software costs are amortized on a straight-line basis over the estimated useful life of the asset, which is currently three to five years.
Intangibles-in-progress include capitalizable development costs incurred before the related software is placed in service.
We also have intangible assets for customer relationships, developed technology, and trade names and trademarks which we recorded in connection with acquisitions and strategic partnerships. Purchased intangible assets with a determinable economic life are carried at cost less accumulated amortization. These intangible assets are amortized over the estimated useful life of the asset on a straight-line basis.
For each of the intangible assets described above, we have removed fully amortized assets from the cost and accumulated amortization amounts disclosed.
Recoverability of Intangible Assets with Definite Lives and Other Long-Lived Assets
We evaluate intangible assets and other long-lived assets, including our lease right of use assets, for impairment whenever events or circumstances indicate that they may not be recoverable. Recoverability is measured by comparing the carrying amount of an asset group to future undiscounted net cash flows expected to be generated. We group assets for purposes of such review at the lowest level for which identifiable cash flows of the asset group are largely independent of the cash flows of the other groups of assets and liabilities. If this comparison indicates impairment, the amount of impairment to be recognized is calculated as the difference between the carrying value and the fair value of the asset group.
Business Combinations
Business Combinations
We recognize identifiable assets acquired and liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions for the preliminary purchase price allocation process to value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that we identify adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations. We recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined.
We record contingent consideration at its preliminary estimated fair value at the date of acquisition. The current portion of contingent consideration is recorded within accrued expenses and other current liabilities, and the long-term portion is recorded within other long-term liabilities in our consolidated balance sheets. The fair value of contingent consideration is remeasured each reporting period. Measurement period adjustments, if any, to the preliminary estimated fair value as of the
acquisition date are recorded to goodwill during the measurement period, which may be up to one year from the acquisition date. Changes in fair value as a result of updated assumptions after the acquisition date are recorded in general and administrative expenses in the consolidated statements of operations.
Technology and Development
Technology and Development. Technology and development expenses consist of headcount-related expenses, including salaries, benefits, bonuses and share-based compensation expense for individuals engaged in the design, development and testing of our products, mobile apps and websites and the tools and apps that support our products. Technology and development expenses also include equipment and software maintenance costs and depreciation expense.
Research and development costs are expensed as incurred and are recorded in technology and development expenses. For the years ended December 31, 2025, 2024 and 2023, expenses attributable to research and development totaled $553 million, $543 million and $545 million, respectively.
Share-Based Compensation
Share-Based Compensation. We measure compensation expense for all share-based awards at fair value on the date of grant and recognize compensation expense over the service period on a straight-line basis for awards expected to vest.
We use the Black-Scholes-Merton option-pricing model to determine the fair value for option awards. In valuing our option awards, we make assumptions about risk-free interest rates, dividend yields, volatility and weighted-average expected lives. We account for forfeitures as they occur. Risk-free interest rates are derived from U.S. Treasury securities as of the option award grant date. Expected dividend yield is based on our historical cash dividend payments, which have been zero to date. The expected volatility for our Class C capital stock is estimated using our historical volatility. The weighted-average expected life of the option awards is estimated based on our historical exercise data.
When determining the grant date fair value of share-based awards, management considers whether an adjustment is required to the observable market price or volatility of the Company’s Class C capital stock used in the valuation as a result of material non-public information.
For issuances of restricted stock units, we determine the fair value of the award based on the market value of our Class C capital stock, as applicable, at the date of grant.
Income Taxes
Income Taxes
We use the asset and liability approach for accounting and reporting income taxes, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial statement and tax bases of assets and liabilities at the applicable enacted tax rates. A valuation allowance against deferred tax assets would be established if, based on the weight of available evidence, it is more likely than not (a likelihood of more than 50%) that some or all of the deferred tax assets are not expected to be realized.
We establish reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. We adjust these reserves in light of changing facts and circumstances, such as the closing of a tax audit, new tax legislation or the change of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made. Interest and penalties related to unrecognized tax benefits are recorded as income tax expense.
Recently Adopted Accounting Standards And Recently Issued Accounting Standards Not Yet Adopted
Recently Adopted Accounting Standards
In December 2023, the FASB issued guidance to enhance the income tax rate reconciliation disclosure requirements and to provide clarity on disclosure requirements for income taxes. We adopted this guidance on a prospective basis for the annual period ending December 31, 2025. While the adoption of this guidance has resulted in additional disclosures related to income taxes, it did not have a material impact on our consolidated financial statements. Refer to Note 9 for additional information related to our income tax disclosures.
Recently Issued Accounting Standards Not Yet Adopted
In November 2024, the FASB issued guidance that will require disclosure of specified information about certain costs and expenses included within an entity’s consolidated financial statements. This guidance is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027, and can be applied on a prospective or retrospective basis, with early adoption permitted. We have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.
In September 2025, the FASB issued guidance that modernizes the accounting for internal-use software costs by removing all references to project development stages. Under this guidance, eligible software development costs begin capitalization once management has authorized and committed to funding the project and it is probable the project will be completed and used to perform the function intended. This guidance is effective for annual and interim periods beginning after December 15, 2027, and can be applied on a prospective, retrospective or modified basis, with early adoption permitted. We have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.
In December 2025, the FASB issued guidance that improves the navigability of interim reporting guidance and clarifies when it applies. Under this guidance, entities must disclose events since the end of the last annual reporting period that have a material impact on the entity. This guidance is not intended to change the fundamental nature of interim reporting or expand or reduce current interim disclosure requirements. This guidance is effective for annual and interim periods beginning after December 15, 2027, and can be applied on a prospective or retrospective basis, with early adoption permitted. We have not yet determined the impact the adoption of this guidance will have on our consolidated financial statements.
Fair Value Measurements
We apply fair value measurements on a recurring and, as otherwise required, on a nonrecurring basis. Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The standards also establish a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1 — Quoted prices in active markets for identical assets or liabilities.
Level 2 — Assets and liabilities valued based on observable market data for similar instruments, such as quoted prices for similar assets or liabilities.
Level 3 — Unobservable inputs that are supported by little or no market activity; instruments valued based on the best available data, some of which is internally developed, and considers risk premiums that a market participant would require.
We apply the following methods and assumptions in estimating our fair value measurements:
Cash equivalents — The fair value measurement of money market funds is based on quoted market prices in active markets (Level 1). The fair value measurement of other cash equivalents is based on observable market-based inputs principally derived from or corroborated by observable market data (Level 2).
Short-term investments — The fair value measurement of our short-term investments is based on observable market-based inputs or inputs that are derived principally from or corroborated by observable market data by correlation or other means (Level 2).
Restricted cash — The carrying value of restricted cash approximates fair value due to the short period of time that amounts are held in escrow (Level 1).
Mortgage loans held for sale — The fair value of mortgage loans held for sale is generally calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics (Level 2).
Forward contracts — The fair value of mandatory loan sales commitments and derivative instruments such as forward sales of MBSs that are utilized as economic hedging instruments is calculated by reference to quoted prices for similar assets (Level 2).
Contingent consideration — In December 2023, Zillow Group acquired Follow Up Boss for $399 million in cash, net of cash acquired, and contingent consideration of up to $100 million, payable over a three-year period upon achievement of certain performance metrics. During the year ended December 31, 2025, we paid $33 million in cash to settle the first earn out payment, most of which represented settlement of the acquisition date fair value. The fair value of the contingent consideration is estimated using a Monte Carlo simulation which considers the probabilities of the achievement of certain performance metrics (Level 3).
The discount rates used in our valuation of contingent consideration are based on our estimated cost of debt and are directly related to the fair value of contingent consideration. An increase in the discount rate, in isolation, would result in a decrease in the fair value measurement. Conversely, a decrease in the discount rate, in isolation, would result in an increase in the fair value measurement. The probabilities of achieving the relevant performance metrics used in our valuation of contingent consideration are directly related to the fair value of contingent consideration, as an increase in the probability, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the probability, in isolation, would result in a decrease in the fair value measurement.
The following table presents the ranges and weighted average unobservable inputs used in determining the fair value of contingent consideration as of the dates presented:

92% - 100%
Weighted average
5.26%98%5.81%96%
IRLCs — The fair value of IRLCs is calculated by reference to quoted prices in secondary markets for commitments to sell mortgage loans with similar characteristics. Expired commitments are excluded from the fair value measurement. Since not all IRLCs will become closed loans, we adjust our fair value measurements for the estimated amount of IRLCs that will not close. This adjustment is effected through the pull-through rate, which represents the probability that an IRLC will ultimately result in a closed loan. For IRLCs that are canceled or expire, any recorded gain or loss is reversed at the end of the commitment period (Level 3).
The pull-through rate is based on estimated changes in market conditions, loan stage and historical borrower behavior. Pull-through rates are directly related to the fair value of IRLCs as an increase in the pull-through rate, in isolation, would result in an increase in the fair value measurement. Conversely, a decrease in the pull-through rate, in isolation, would result in a decrease in the fair value measurement. Changes in the fair value of IRLCs are included within revenue in our consolidated statements of operations.
