Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Nature of Operations Google was incorporated in California in September 1998 and re-incorporated in the State of Delaware in August 2003. In 2015, we implemented a holding company reorganization, and as a result, Alphabet Inc. ("Alphabet") became the successor issuer to Google. We generate revenues by delivering relevant, cost-effective online advertising; cloud-based solutions that provide enterprise customers of all sizes with infrastructure, platform services, and applications; and sales of other products and services, such as fees received for subscription-based products, apps and in-app purchases, and devices. Basis of Consolidation The consolidated financial statements of Alphabet include the accounts of Alphabet and entities consolidated under the variable interest and voting models. Intercompany balances and transactions have been eliminated. Unaudited Interim Financial Information These unaudited interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP), and in our opinion, include all adjustments of a normal recurring nature necessary for fair financial statement presentation. Interim results are not necessarily indicative of the results to be expected for the full year ending December 31, 2026. We have made estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Actual results could differ materially from these estimates. These consolidated financial statements and other information presented in this Form 10-Q should be read in conjunction with the consolidated financial statements and the related notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the SEC. There have been no material changes to our significant accounting policies from our Annual Report on Form 10-K for the year ended December 31, 2025, except for as described below. Use of Estimates Preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Actual results could differ materially from these estimates due to uncertainties. On an ongoing basis, we evaluate our estimates, including those related to the allowance for credit losses; contingent liabilities; fair values of financial instruments, intangible assets and goodwill; income taxes; inventory; and useful lives of intangible assets and property and equipment, among others. We base our estimates on assumptions, both historical and forward looking, that are believed to be reasonable, and the results of which form the basis for making judgments about the carrying values of assets and liabilities. Acquired Intangible Assets Intangible assets with definite lives are amortized over their estimated useful lives on a straight-line basis generally over periods ranging from one to 10 years, and are subsequently removed from the presentation of gross intangible assets and accumulated amortization once they are fully amortized. Assets Held for Sale We consider assets to be held for sale in the period when all of the criteria for a qualifying plan of sale are met. Upon designation as held for sale, we record the assets at the lower of their carrying value or their estimated fair value, reduced for the cost to sell the assets, and cease depreciation. Long-lived assets classified as held for sale are measured at fair value on a nonrecurring basis. Recently Issued Accounting Pronouncements Not Yet Adopted In November 2024, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2024-03 "Income Statement: Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40)" to improve the disclosures about an entity’s expenses. Upon adoption, we will be required to disclose in the notes to the financial statements a disaggregation of certain expense categories included within the relevant expense captions on the consolidated statements of income. The standard is effective for our 2027 annual period, and our interim periods beginning in 2028, with early adoption permitted. The standard can be applied either prospectively or retrospectively. We are currently assessing adoption timing, the method of adoption, and the effect that the updated standard will have on our financial statement disclosures. In September 2025, the FASB issued ASU 2025-06 "Intangibles: Goodwill and Other‒Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software" to modernize the accounting for software costs under Subtopic 350-40, Intangibles‒Goodwill and Other‒Internal-Use Software (referred to as “internal-use software”). Upon adoption, we will be required to account for internal-use software under the updated capitalization criteria. The standard is effective for our interim and annual 2028 periods, with early adoption permitted. The standard can be applied either prospectively, retrospectively, or under a modified transition approach. We are currently assessing adoption timing, the method of adoption, and the effect that the updated standard will have on our consolidated financial statements. Prior Period Reclassifications Certain amounts in prior periods have been reclassified to conform with current period presentation.
