Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements include Zillow Group, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. These condensed consolidated financial statements have been prepared in conformity with GAAP and applicable rules and regulations of the SEC regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the audited financial statements and accompanying notes included in Zillow Group, Inc.’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024. The condensed consolidated balance sheet as of December 31, 2024, included herein, was derived from the audited financial statements of Zillow Group, Inc. as of that date. Certain reclassifications of prior period amounts have been made to conform to the current period presentation. The unaudited condensed consolidated interim financial statements, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, necessary to present fairly our financial position as of September 30, 2025 and our results of operations, comprehensive income (loss) and shareholders’ equity for the three and nine month periods ended September 30, 2025 and 2024, and cash flows for the nine month periods ended September 30, 2025 and 2024. The results for the three and nine months ended September 30, 2025 are not necessarily indicative of the results to be expected for the year ending December 31, 2025, for any interim period, or for any other future year. 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 broader economy may result in additional uncertainty with respect to estimates, judgments and assumptions, which may materially impact the estimates previously listed, among others. Recently Issued Accounting Standards Not Yet Adopted 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. This guidance is effective for annual periods beginning after December 15, 2024, and can be applied on a prospective or retrospective basis, with early adoption permitted. We expect to adopt this guidance for the annual period ending December 31, 2025. While we anticipate this guidance will result in additional disclosures related to income taxes, we do not expect this new guidance to have a material impact on our consolidated financial statements. 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.
