Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Our consolidated financial statements include the accounts of Snap Inc. and our wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Our fiscal year ends on December 31. These unaudited interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as filed with the Securities and Exchange Commission (“SEC”) in February 2023 (the “Annual Report”). In our opinion, the unaudited interim consolidated financial statements include all adjustments of a normal recurring nature necessary for the fair presentation of our financial position, results of operations, and cash flows. The results of operations for the three months ended March 31, 2023 are not necessarily indicative of the results to be expected for the year ending December 31, 2023. There have been no changes to our significant accounting policies described in our Annual Report that have had a material impact on our consolidated financial statements and related notes.
Use of Estimates	Use of Estimates The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements. 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 from those estimates. Key estimates relate primarily to determining the fair value of assets and liabilities assumed in business combinations, evaluation of contingencies, uncertain tax positions, and the fair value of strategic investments. 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
Future Stock Split to be Effected in the Form of a Stock Dividend	Future Stock Split to be Effected in the Form of a Stock Dividend In July 2022, our board of directors determined that it was advisable and in our best interest to approve a stock split to be effected in the form of a special dividend of one share of Class A common stock on each outstanding share of our common stock at a future date (the “Future Stock Split”). In connection with the Future Stock Split, we entered into certain agreements (the “Co-Founder Agreements”) with Evan Spiegel and Robert Murphy, our co-founders, and certain of their respective affiliates requiring them, among other things, to convert shares of Class B common stock and Class C common stock into Class A common stock under certain circumstances. The Future Stock Split will not be declared and paid until the later of (i) June 30, 2023 and (ii) the first business day following the date on which the average of the volume weighted average price per share of Class A common stock equals or exceeds $40 per share for 65 consecutive trading days. If this does not occur by July 21, 2032, the Future Stock Split will not be declared and paid, and the Co-Founder Agreements will terminate. No adjustments have been made to share or per share amounts for Class A common stock in the accompanying consolidated financial statements for the effects of the Future Stock Split as these triggering conditions have not been met.
