Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	2. Basis of Presentation and Significant Accounting Policies Basis of Presentation of Unaudited Interim Financial Information Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) regarding interim financial information. Our consolidated financial statements include the accounts of Reddit, Inc. and our wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Certain information and disclosures normally included in the annual consolidated financial statements prepared in accordance with U.S. GAAP have been omitted. Accordingly, the unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2025 (our “Annual Report”). The unaudited interim consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and reflect, in our opinion, all the adjustments of a normal, recurring nature that are necessary for the fair statement of our financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results expected for the full year or any other period. Other than described below, there have been no changes to our significant accounting policies described in the “Notes to the Consolidated Financial Statements” included in our audited consolidated financial statements and related notes as of and for the year ended December 31, 2025 included in our Annual Report that have had a material impact on our consolidated financial statements and accompanying notes. Use of Estimates The preparation of the unaudited consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Management’s estimates are based on historical information available as of the date of the consolidated financial statements and various other assumptions that we believe are reasonable under the circumstances. Actual results could differ materially from those estimates. Significant estimates relate primarily to the valuation of deferred tax assets, determining the fair value of stock-based awards, the fair value of assets and liabilities assumed in business combinations, and the incremental borrowing rate used to determine operating lease right-of-use assets and lease liabilities. On an ongoing basis, management evaluates our estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. Income Taxes We account for income taxes using the asset and liability method. We recognize deferred tax assets and liabilities for temporary differences between the financial reporting and tax bases of assets and liabilities using the enacted statutory tax rates in effect for the years in which we expect the differences to reverse. We establish valuation allowances to reduce the total deferred tax assets to the amount we believe is more likely than not to be realized. In assessing the need for a valuation allowance, we consider all available evidence, both positive and negative, including past operating results and estimates of future taxable income. Our judgment regarding the timing and amount of the valuation allowance release is subject to change based on a number of factors, including but not limited to, the level of profitability (income before income taxes adjusted for permanent differences) that we are able to accurately forecast, as well as the amount of our tax deductible stock-based compensation, which is dependent upon our publicly traded share price, and macroeconomic conditions, among other factors. In the event that we change our determination as to the amount of deferred tax assets that can be realized, we will adjust our valuation allowance with a corresponding impact to the provision for (benefit from) income taxes in the period in which such determination is made. Concentration of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents, restricted cash, marketable securities, and accounts receivable. We maintain cash and cash equivalents with several financial institutions. We believe that the financial institutions that hold our cash and cash equivalents are financially sound and, accordingly, minimal credit risks exist with respect to these balances. We maintain investments in U.S. and non-U.S. government securities, investment-grade corporate and government agency securities, time deposits, commercial paper, and money market accounts that carry high credit ratings and accordingly, minimal credit risk exists with respect to these balances. Accounting Pronouncements Not Yet Adopted In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires an entity to disclose disaggregated information about certain income statement expense line items. The standard is effective for us beginning January 1, 2027, with early adoption permitted. We are currently evaluating the impact the adoption will have on our disclosures. In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which aims to modernize the accounting for internal-use software costs to better align with current software development practices by removing references to prescriptive software development stages and establishing a new principle for when to begin capitalizing such costs. The standard is effective for us beginning January 1, 2028. We are currently evaluating the impact the adoption will have on our consolidated financial statements.
