Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Snap Inc. is a camera company. Snap Inc. (“we,” “our,” or “us”) was formed as Future Freshman, LLC, a California limited liability company, in 2010. We changed our name to Toyopa Group, LLC in 2011, incorporated as Snapchat, Inc., a Delaware corporation, in 2012, and changed our name to Snap Inc. in 2016. Snap Inc. is headquartered in Venice, California. Our flagship product, Snapchat, is a camera application that was created to help people communicate through short videos and images called “Snaps.” 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 prospectus dated March 1, 2017, as filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (File No. 333-215866) (“Prospectus”). 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 and six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017. Other than described below, there have been no changes to our significant accounting policies described in our Prospectus that have had a material impact on our consolidated financial statements and related notes. Initial Public Offering In March 2017, we completed our initial public offering (“IPO”) in which we issued and sold 160.3 million shares of Class A common stock, inclusive of the over-allotment, at a public offering price of $17.00 per share and excluding shares sold in the IPO by certain of our existing stockholders. We received net proceeds of $2.6 billion after deducting underwriting discounts and commissions of $68.1 million and other offering expenses of $14.7 million. On the closing of the IPO, all shares of our then-outstanding convertible preferred stock other than Series FP preferred stock automatically converted into an aggregate of 246.8 million shares of Class B common stock and all outstanding shares of Series FP preferred stock automatically converted into 215.9 million shares of Class C common stock. Following the IPO, we have three classes of authorized common stock – Class A common stock, Class B common stock, and Class C common stock. Restricted stock units (“RSUs”) granted to employees before January 1, 2017 (“Pre-2017 RSUs”) included both service-based and performance conditions to vest in the underlying common stock. The performance condition related to these awards was satisfied on the effectiveness of the registration statement for our IPO, which occurred in March 2017. On the effectiveness of the registration statement for our IPO, we recognized $1.3 billion of stock-based compensation expense for Pre-2017 RSUs. To meet the related tax withholding requirements, we withheld 12.1 million of the 26.7 million shares of common stock issued. Based on the public offering price of $17.00 per share, the tax withholding obligation for these vested Pre-2017 RSUs was $206.6 million. In addition, on the closing of the IPO, our Chief Executive Officer (“CEO”) received an RSU award (“CEO award”) for 37.4 million shares of Series FP preferred stock, which automatically converted into an equivalent number of shares of Class C common stock on the closing of the IPO. The CEO award represented 3.0% of all outstanding shares on the closing of the IPO, including shares sold by us in the IPO and vested stock options and RSUs, net of shares withheld to satisfy tax withholding obligations, on the closing of the IPO. The CEO award vested immediately on the closing of the IPO, and such shares will be delivered to the CEO in equal quarterly installments over three years beginning in the third full calendar quarter following the IPO. There is no continuing service requirement for our CEO. The stock-based compensation expense recognized related to the CEO award was $636.6 million, which is based on the vesting of 37.4 million shares of Class C common stock on the closing of the IPO, at the public offering price of $17.00 per share. The future tax benefits on settlement of the above RSUs is not expected to be material as currently we have established valuation allowances to reduce our net deferred tax assets to the amount that is more likely than not to be realized. The majority of the future tax benefits that arise on settlement of the above RSUs are in jurisdictions for which our net deferred tax assets have a full valuation allowance. 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 stock-based awards. 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. Recent Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfer of Assets Other than Inventory In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). Revenue Recognition, The most significant aspect of our evaluation of Topic 606 related to ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). We do not expect the new standard to have a material impact on our consolidated financial statements. We expect to adopt Topic 606 during the first quarter of 2018. We are still evaluating the use of either the retrospective or modified retrospective transition method.

Earnings Per Share [Abstract]
Net Loss per Share	2. Net Loss per Share We compute net loss per share using the two-class method required for multiple classes of common stock and participating securities. Our participating securities include any shares issued on the early exercise of stock options subject to repurchase because holders of such shares have non-forfeitable dividend rights in the event a dividend is paid on common stock. Before the IPO, our participating securities also included Series D, E, F, and FP preferred stock and Series A, A-1, B, and C convertible preferred stock. The rights, including the liquidation and dividend rights, of the Class A common stock and Class B common stock, and the Series D, E, F, and FP preferred stock were substantially identical, other than voting rights. Accordingly, the Class A common stock, Class B common stock, and the Series D, E, F, and FP shared equally in our net losses. The holders of early exercised shares subject to repurchase and the holders of Series A, A-1, B, and C convertible preferred stock did not have a contractual obligation to share in our losses, and as a result our net losses were not allocated to these participating securities. In connection with our IPO, our Series D, E, and F preferred stock converted on a one-to-one basis into Class B common stock, and our Series FP preferred stock converted on a one-to-one basis into Class C common stock. The liquidation and dividend rights of the aforementioned preferred series are substantially identical to the rights of the common classes into which they converted. Accordingly, we have presented the Series D, E, and F preferred stock outstanding before the IPO together with the Class B common stock, and the Series FP preferred stock outstanding before the IPO together with the Class C common stock for purposes of calculating net loss per share. The prior period presentation has been adjusted to conform to our current period presentation. Also in connection with our IPO, our Series A, A-1, B, and C preferred stock converted on a one-to-one basis into Class B common stock. The shares of Class B common stock that resulted from the conversion of the Series A, A-1, B, and C preferred stock are weighted in the denominator of net loss per share for Class B common stock for the portion of the time outstanding subsequent to our IPO. Basic net loss per share is computed by dividing net loss attributable to each class of stockholders by the weighted-average number of shares of stock outstanding during the period. Vested RSUs that have not been settled, including the vested CEO award, have been included in the appropriate common share class used to calculate basic net loss per share. For the calculation of diluted net loss per share, net loss per share attributable to common stockholders for basic net loss per share is adjusted by the effect of dilutive securities, including awards under our equity compensation plans. Diluted net loss per share attributable to common stockholders is computed by dividing the resulting net loss attributable to common stockholders by the weighted-average number of fully diluted common shares outstanding. For the three and six months ended June 30, 2017 and 2016 our potential dilutive shares relating to stock options, RSUs, and common stock subject to repurchase, and, for the 2016 periods, shares of convertible Series A, A-1, B, and C preferred stock were not included in the computation of diluted net loss per share as the effect of including these shares in the calculation would have been anti-dilutive. The numerators and denominators of the basic and diluted net loss per share computations for our common stock are calculated as follows for the three and six months ended June 30, 2017 and 2016: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (in thousands, except per share data) Class A Common (1) Class B Common (2) Class C Common (3) Class A Common Class B Common (2) Class C Common (3) Class A Common (1) Class B Common (2) Class C Common (3) Class A Common Class B Common (2) Class C Common (3) Numerator: Net loss $ (248,613 ) $ (102,730 ) $ (91,750 ) $ (70,050 ) $ (14,744 ) $ (31,100 ) $ (1,524,926 ) $ (543,768 ) $ (583,236 ) $ (133,924 ) $ (25,314 ) $ (61,232 ) Net loss attributable to common stockholders $ (248,613 ) $ (102,730 ) $ (91,750 ) $ (70,050 ) $ (14,744 ) $ (31,100 ) $ (1,524,926 ) $ (543,768 ) $ (583,236 ) $ (133,924 ) $ (25,314 ) $ (61,232 ) Denominator: Basic shares: Weighted-average common shares - Basic 686,456 283,651 253,336 487,398 102,591 216,390 627,209 223,654 239,888 474,784 89,742 217,078 Diluted shares: Weighted-average common shares - Diluted 686,456 283,651 253,336 487,398 102,591 216,390 627,209 223,654 239,888 474,784 89,742 217,078 Net loss per share attributable to common stockholders: Basic $ (0.36 ) $ (0.36 ) $ (0.36 ) $ (0.14 ) $ (0.14 ) $ (0.14 ) $ (2.43 ) $ (2.43 ) $ (2.43 ) $ (0.28 ) $ (0.28 ) $ (0.28 ) Diluted $ (0.36 ) $ (0.36 ) $ (0.36 ) $ (0.14 ) $ (0.14 ) $ (0.14 ) $ (2.43 ) $ (2.43 ) $ (2.43 ) $ (0.28 ) $ (0.28 ) $ (0.28 ) (1) Class A common stock includes the issuance of 160.3 million shares of Class A common stock issued by us in connection with our IPO.

Stockholders' Equity	3. Stockholders’ Equity We maintain three share-based employee compensation plans: the 2017 Equity Incentive Plan (“2017 Plan”), the 2014 Equity Incentive Plan (“2014 Plan”), and the 2012 Equity Incentive Plan (“2012 Plan”, and collectively with the 2017 Plan and the 2014 Plan, the “Stock Plans”). In January 2017, our board of directors adopted the 2017 Plan, and in February 2017 our stockholders approved the 2017 Plan, effective on March 1, 2017, which serves as the successor to the 2014 Plan and 2012 Plan and provides for the grant of incentive stock options to employees, including employees of any parent or subsidiary, and for the grant of nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards, performance cash awards, and other forms of stock awards to employees, directors, and consultants, including employees and consultants of our affiliates. We do not expect to grant any additional awards under the 2014 Plan or 2012 Plan as of the effective date of the 2017 Plan, other than awards for up to 2,500,000 shares of Class A common stock to our employees and consultants in France under the 2014 Plan. Outstanding awards under the 2014 Plan and 2012 Plan continue to be subject to the terms and conditions of the 2014 Plan and 2012 Plan, respectively. Shares available for grant under the 2014 Plan and 2012 Plan, which were reserved but not issued or subject to outstanding awards under the 2014 Plan or 2012 Plan, respectively, as of the effective date of the 2017 Plan, were added to the reserves of the 2017 Plan. We have initially reserved 87,270,108 shares of our Class A common stock for future issuance under the 2017 Plan. An additional number of shares of Class A common stock will be added to the 2017 Plan equal to (i) 96,993,064 shares of Class A common stock reserved for future issuance pursuant to outstanding stock options and unvested RSUs under the 2014 Plan, (ii) 37,228,865 shares of Class A common stock issuable on conversion of Class B common stock underlying stock options and unvested RSUs outstanding the 2012 Plan, (iii) 17,858,235 shares of Class A common stock that were reserved for issuance under the 2014 Plan as of the date the 2017 Plan became effective, (iv) 11,004,580 shares of Class A common stock issuable on conversion Class B common stock that were reserved for issuance under the 2012 Plan as of the date the 2017 Plan became effective, and (v) a maximum of 86,737,997 shares of Class A common stock that will be added pursuant to the following sentence. With respect to each share that returns to the 2017 Plan pursuant to (i) and (ii) of the prior sentence that was associated with an award that was outstanding under the 2014 Plan and 2012 Plan as of October 31, 2016, an additional share of Class A common stock will be added to the share reserve of the 2017 Plan, up to a maximum of 86,737,997 shares st The following table summarizes the RSU award activity under the Stock Plans during the six months ended June 30, 2017: Class A Outstanding RSUs Class B Outstanding RSUs Weighted- Average Grant Date Fair Value per RSU (in thousands, except per share data) Unvested at December 31, 2016 152,114 28,581 $ 15.50 Granted 39,700 — $ 17.41 Vested (25,210 ) (13,981 ) $ 14.99 Forfeited (3,536 ) (268 ) $ 15.51 Unvested at June 30, 2017 163,068 14,332 $ 16.04 Total unrecognized compensation cost related to Pre-2017 RSUs was $1.0 billion as of June 30, 2017 and is expected to be recognized over a weighted-average period of 2.9 years. All RSUs granted after December 31, 2016 vest on the satisfaction of only a service-based condition (“Post-2017 RSUs”). Total unrecognized compensation cost related to Post-2017 RSUs was $597.4 million as of June 30, 2017 and is expected to be recognized over a weighted-average period of 5.3 years. The service condition is generally satisfied over four years, 10% after the first year of service, 20% over the second year, 30% over the third year, and 40% over the fourth year. In limited instances, we have issued Post-2017 RSUs with vesting periods in excess of four years. For the six months ended June 30, 2017, for RSUs issued to employees, we withheld 12.3 million shares of common stock (“net settlement”) and remitted $208.4 million in cash to meet the related tax withholding requirements on behalf of our employees. In July 2017, we withheld an additional 7.8 million shares of common stock and remitted approximately $105.0 million in cash to satisfy the related tax withholding requirements on behalf of our employees. We will continue to evaluate the net settlement of RSUs that vest in the future. The table below presents stock option awards that entitle the holder to an additional share of Class A common stock on exercise. The total stock options granted and underlying common stock fair value do not give effect to the additional Class A common stock. The following table summarizes the stock option award activity under the Stock Plans during the six months ended June 30, 2017: Class A Number of Shares Class B Number of Shares Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (1) (in thousands, except per share data) Outstanding at December 31, 2016 1,266 21,186 $ 2.26 6.97 $ 682,565 Granted — — $ — — $ — Exercised (4 ) (2,700 ) $ 0.29 — $ — Forfeited — — $ — — $ — Outstanding at June 30, 2017 1,262 18,486 $ 2.53 6.47 $ 651,879 (1) The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying stock option awards and the assessed fair value of our common stock as of December 31, 2016 or the closing market price of our Class A common stock as of June 30, 2017. Total unrecognized compensation cost related to stock options was $37.0 million as of June 30, 2017 Stock-Based Compensation Expense by Function Total stock-based compensation expense by function is as follows: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 (in thousands) Cost of revenue $ 2,223 $ 128 $ 21,931 $ 282 Research and development 163,848 2,700 881,928 5,348 Sales and marketing 20,558 553 180,284 1,328 General and administrative 58,399 1,361 1,153,006 3,322 Total $ 245,028 $ 4,742 $ 2,237,149 $ 10,280 2017 Employee Stock Purchase Plan In January 2017, our board of directors adopted the 2017 Employee Stock Purchase Plan (“2017 ESPP”). Our stockholders approved the 2017 ESPP in February 2017. The 2017 ESPP became effective in connection with the IPO. A total of 16,484,690 shares of Class A common stock were initially reserved for issuance under the 2017 ESPP. No shares of our Class A common stock have been purchased under the 2017 ESPP. The number of shares of our Class A common stock reserved for issuance will automatically increase on January 1st of each calendar year, beginning on January 1, 2018 through January 1, 2027, by the lesser of (1) 1.0% of the total number of shares of our common stock outstanding on the last day of the calendar month before the date of the automatic increase, and (2) 15,000,000 shares; provided that before the date of any such increase, our board of directors may determine that such increase will be less than the amount set forth in clauses (1) and (2).

Business Acquisitions	4. Business Acquisitions Zenly SAS In May 2017, we acquired Zenly SAS, a company that develops a location-based social media application that allows users to see where their friends are on a map. The purpose of the acquisition was to enhance the functionality of our platform. The total consideration paid was $213.3 million in cash, of which $196.1 million represents purchase consideration and includes $186.8 million in cash paid to the sellers and $9.3 million of liabilities due to the sellers. The remaining $17.2 million of total consideration transferred represents compensation for future employment services. The allocation of purchase price is preliminary and is subject to additional information related to the liabilities that existed as of the acquisition date. The preliminary allocation of the total purchase consideration for this acquisition is estimated as follows: Total (in thousands) Cash $ 22,610 Technology 23,000 Goodwill 154,353 Net deferred tax liability (2,418 ) Other assets acquired and liabilities assumed, net (1,428 ) Total $ 196,117 The goodwill amount represents synergies related to our existing platform expected to be realized from this business combination and assembled workforce. The associated goodwill and intangible assets are not deductible for tax purposes. Other Acquisitions In June 2017, we acquired a component of a business from a social advertising software company that was integrated with our existing advertising platform and adds advertising tools and creative solutions to our advertising customers. In addition, in March 2017, we acquired all outstanding shares of a company that operates a cloud hosted platform for building content online. The company was acquired to enhance the functionality of our platform. The total purchase consideration for these acquisitions was $62.1 million, which included $60.2 million in cash and $1.9 million recorded in other liabilities on the consolidated balance sheets. The allocation of the total purchase consideration for the above acquisitions is as follows: Total (in thousands) Technology $ 39,000 Customer relationships 500 Goodwill 24,135 Net deferred tax liability (1,710 ) Other assets acquired and liabilities assumed, net 200 Total $ 62,125 The goodwill amount represents synergies related to our existing platform expected to be realized from these business combinations and assembled workforce. Of the technology intangible assets and goodwill in the above table, $30.5 million and $11.5 million is deductible for tax purposes, respectively. Additional Information on 2017 Acquisitions For all acquisitions in 2017, we provided for a combined $122.5 million in the form of RSUs to certain continuing employees of the companies in exchange for future service. In addition, unaudited pro forma results of operations assuming the above acquisitions had taken place at the beginning of each period are not provided because the historical operating results of the acquired entities were not material and pro forma results would not be materially different from reported results for the periods presented.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	6. Commitments and Contingencies Commitments Leases We entered into various non-cancelable lease agreements for certain of our offices with original lease periods expiring between 2017 and 2027. Certain of the arrangements have free rent periods or escalating rent payment provisions. We recognize rent expense under such arrangements on a straight-line basis. Our future minimum lease payments required under these non-cancelable operating lease obligations as of June 30, 2017, are as follows: Operating Leases (in thousands) Remainder of 2017 $ 17,686 2018 45,200 2019 55,064 2020 55,486 2021 54,652 Thereafter 182,357 Total minimum lease payments $ 410,445 Operating lease expenses for the three months ended June 30, 2017 and 2016 were $11.8 and $5.7, respectively, and $24.7 million and $10.7 million for the six months ended June 30, 2017 and 2016, respectively. We have several lease agreements where we are deemed the owner under build-to-suit lease accounting. The fair value of the leased property and corresponding financing obligations are included in property and equipment, net and other liabilities, respectively, on our consolidated balance sheets as of June 30, 2017. Our future minimum lease payments required under non-cancelable financing lease obligations, which exclusively relate to our build-to-suit leases, as of June 30, 2017, are as follows: Financing Leases (in thousands) Remainder of 2017 $ 2,340 2018 4,726 2019 4,796 2020 4,947 2021 5,092 Thereafter 25,953 Total minimum lease payments $ 47,854 We recognize an increase in the fair value of the asset as additional building costs are incurred during the construction period and a corresponding increase in the lease financing obligation for any construction costs to be reimbursed by the landlord. As of June 30, 2017, $15.7 million of lease financing obligations are included in other liabilities on our consolidated balance sheets. Contractual Commitments We have non-cancelable contractual agreements related to the hosting of our data storage processing, storage, and other computing services. In January 2017, we entered into the Google Cloud Platform License Agreement. Under the agreement, we were granted a license to access and use certain cloud services. The agreement has an initial term of five years and we are required to purchase at least $400.0 million of cloud services in each year of the agreement, though for each of the first four years, up to 15% of this amount may be moved to a subsequent year. If we fail to meet the minimum purchase commitment during any year, we are required to pay the difference. In March 2016, we entered into the AWS Enterprise Agreement for the use of cloud services from Amazon Web Services, Inc. (“AWS”) that was amended in March 2016, and again in February 2017. Such agreement will continue indefinitely until terminated by either party. Under the February 2017 addendum to the agreement, we committed to spend $1.0 billion between January 2017 and December 2021 on AWS services ($50.0 million in 2017, $125.0 million in 2018, $200.0 million in 2019, $275.0 million in 2020, and $350.0 million in 2021). If we fail to meet the minimum purchase commitment during any year, we are required to pay the difference. Any such payment may be applied to future use of AWS services during the addendum term, although it will not count towards meeting the future minimum purchase commitments under the addendum. We also have various other non-cancelable contractual commitments related to purchase agreements. Approximately $29.0 million of our other purchase commitments relate to hardware inventory commitments, consistent with our forecasted demand. Our assumptions of future demand for our products are inherently uncertain. The future minimum contractual commitment including commitments less than one year, as of June 30, 2017 for each of the next five years are as follows: Minimum Commitment (in thousands) Remainder of 2017 $ 297,776 2018 537,901 2019 602,492 2020 675,000 2021 750,000 Thereafter 33,333 Total minimum commitments $ 2,896,502 Contingencies We record a loss contingency when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. We also disclose material contingencies when we believe a loss is not probable but reasonably possible. Accounting for contingencies requires us to use judgment related to both the likelihood of a loss and the estimate of the amount or range of loss. Many legal and tax contingencies can take years to be resolved. Pending Matters In April 2016, an individual filed a lawsuit against us and another individual after he was injured in a car accident. The plaintiff alleges that we are liable because the other individual was supposedly using our “speed filter” at the time of the collision. In January 2017, the court dismissed the claim against us. This matter is currently on appeal. Beginning in May 2017, we, certain of our officers and directors, and the underwriters for our IPO were named as defendants in securities class actions purportedly brought on behalf of purchasers of our Class A common stock, alleging violation of securities laws in connection with our IPO. Management believes these lawsuits are without merit and intend to vigorously defend them. Based on the preliminary nature of the proceedings in this case, the outcome of this matter remains uncertain. The outcomes of our legal proceedings are inherently unpredictable, subject to significant uncertainties, and could be material to our financial condition, results of operations, and cash flows for a particular period. For the pending matters described above, it is not possible to estimate the reasonably possible loss or range of loss. We are subject to various other legal proceedings and claims in the ordinary course of business, including certain patent, trademark, and privacy matters. Although occasional adverse decisions or settlements may occur, we do not believe that the final disposition of any of our other pending matters will seriously harm our business, financial condition, results of operations, and cash flows. Settlement In September 2014, two individuals filed a lawsuit against us and our two founders in the Superior Court of California for Los Angeles County. The complaint alleged two causes of action—common-law right of publicity and statutory right of publicity—based on allegations that the defendants improperly used the plaintiffs’ images in promoting Snapchat for Android. In May 2017, the parties entered into a settlement agreement that resolved all claims among the parties. The settlement was not material. In June 2017, the parties filed a stipulation of dismissal with the court. Indemnifications In the ordinary course of business, we may provide indemnifications of varying scope and terms to customers, vendors, lessors, investors, directors, officers, employees, and other parties with respect to certain matters. Indemnification may include losses from our breach of such agreements, services we provide, or third party intellectual property infringement claims. These indemnifications may survive termination of the underlying agreement and the maximum potential amount of future indemnification payments may not be subject to a cap. We have not incurred material costs to defend lawsuits or settle claims related to these indemnifications as of June 30, 2017. We believe the fair value of these liabilities is immaterial and accordingly have no liabilities recorded for these agreements at June 30, 2017.

Income Tax Disclosure [Abstract]
Income Taxes	8. Income Taxes Our tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items arising in that quarter. Our effective tax rate differs from the U.S. statutory tax rate primarily due to valuation allowances on our deferred tax assets as it is more likely than not that some or all of our deferred tax assets will not be realized. Income taxes were an expense of $0.2 million and a benefit of $2.8 million for the three and six months ended June 30, 2017, respectively, as compared to a tax benefit of $0.03 million and an expense of $0.09 million for the three and six months ended June 30, 2016, respectively. The income tax benefit for the six months ended June 30, 2017 was primarily from the partial release of a valuation allowance against our net deferred tax assets. The valuation allowance release was the result of net deferred tax liabilities originating from acquisitions that were an available source of income to realize a portion of our deferred tax assets.

Summary of Significant Accoun18

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2017
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 prospectus dated March 1, 2017, as filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended (File No. 333-215866) (“Prospectus”). 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 and six months ended June 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017. Other than described below, there have been no changes to our significant accounting policies described in our Prospectus that have had a material impact on our consolidated financial statements and related notes.
Initial Public Offering	Initial Public Offering In March 2017, we completed our initial public offering (“IPO”) in which we issued and sold 160.3 million shares of Class A common stock, inclusive of the over-allotment, at a public offering price of $17.00 per share and excluding shares sold in the IPO by certain of our existing stockholders. We received net proceeds of $2.6 billion after deducting underwriting discounts and commissions of $68.1 million and other offering expenses of $14.7 million. On the closing of the IPO, all shares of our then-outstanding convertible preferred stock other than Series FP preferred stock automatically converted into an aggregate of 246.8 million shares of Class B common stock and all outstanding shares of Series FP preferred stock automatically converted into 215.9 million shares of Class C common stock. Following the IPO, we have three classes of authorized common stock – Class A common stock, Class B common stock, and Class C common stock. Restricted stock units (“RSUs”) granted to employees before January 1, 2017 (“Pre-2017 RSUs”) included both service-based and performance conditions to vest in the underlying common stock. The performance condition related to these awards was satisfied on the effectiveness of the registration statement for our IPO, which occurred in March 2017. On the effectiveness of the registration statement for our IPO, we recognized $1.3 billion of stock-based compensation expense for Pre-2017 RSUs. To meet the related tax withholding requirements, we withheld 12.1 million of the 26.7 million shares of common stock issued. Based on the public offering price of $17.00 per share, the tax withholding obligation for these vested Pre-2017 RSUs was $206.6 million. In addition, on the closing of the IPO, our Chief Executive Officer (“CEO”) received an RSU award (“CEO award”) for 37.4 million shares of Series FP preferred stock, which automatically converted into an equivalent number of shares of Class C common stock on the closing of the IPO. The CEO award represented 3.0% of all outstanding shares on the closing of the IPO, including shares sold by us in the IPO and vested stock options and RSUs, net of shares withheld to satisfy tax withholding obligations, on the closing of the IPO. The CEO award vested immediately on the closing of the IPO, and such shares will be delivered to the CEO in equal quarterly installments over three years beginning in the third full calendar quarter following the IPO. There is no continuing service requirement for our CEO. The stock-based compensation expense recognized related to the CEO award was $636.6 million, which is based on the vesting of 37.4 million shares of Class C common stock on the closing of the IPO, at the public offering price of $17.00 per share. The future tax benefits on settlement of the above RSUs is not expected to be material as currently we have established valuation allowances to reduce our net deferred tax assets to the amount that is more likely than not to be realized. The majority of the future tax benefits that arise on settlement of the above RSUs are in jurisdictions for which our net deferred tax assets have a full valuation allowance.
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 stock-based awards. 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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In January 2017, the Financial Accounting Standards Board (“FASB”) issued an Accounting Standards Update (“ASU”) 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfer of Assets Other than Inventory In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). Revenue Recognition, The most significant aspect of our evaluation of Topic 606 related to ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net). We do not expect the new standard to have a material impact on our consolidated financial statements. We expect to adopt Topic 606 during the first quarter of 2018. We are still evaluating the use of either the retrospective or modified retrospective transition method.

Purchase commitment, description				In March 2016, we entered into the AWS Enterprise Agreement for the use of cloud services from Amazon Web Services, Inc. (“AWS”) that was amended in March 2016, and again in February 2017. Such agreement will continue indefinitely until terminated by either party. Under the February 2017 addendum to the agreement, we committed to spend $1.0 billion between January 2017 and December 2021 on AWS services ($50.0 million in 2017, $125.0 million in 2018, $200.0 million in 2019, $275.0 million in 2020, and $350.0 million in 2021). If we fail to meet the minimum purchase commitment during any year, we are required to pay the difference. Any such payment may be applied to future use of AWS services during the addendum term, although it will not count towards meeting the future minimum purchase commitments under the addendum.
