Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Unaudited Interim Condensed Consolidated Financial Information The unaudited condensed consolidated financial statements include the accounts of Datadog, Inc. and its wholly-owned subsidiaries, and have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and following the requirements of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted. These financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair statement of the Company’s financial information. These interim results are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2022 or for any other interim period or for any other future year. The accompanying unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, as filed with the SEC on February 25, 2022 (the “Annual Report”). Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with GAAP. Principles of Consolidation The condensed consolidated financial statements include the accounts of Datadog, Inc. and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such estimates include the fair value of marketable securities, the allowance for credit losses, the fair value of acquired assets and assumed liabilities from business combinations, useful lives of property, equipment, software and finite lived intangibles, stock-based compensation, valuation of long-lived assets and their recoverability, including goodwill, the incremental borrowing rate for operating leases, estimated expected period of benefit for deferred contract costs, fair value of the liability component of the convertible debt, realization of deferred tax assets and uncertain tax positions, revenue recognition and the allocation of overhead costs between cost of revenue and operating expenses. The Company bases its estimates on historical experience and also on assumptions that management considers reasonable. The Company assesses these estimates on a regular basis; however, actual results could materially differ from these estimates. Accounting Pronouncements Recently Adopted In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers ("ASU No. 2021-08"), which intends to improve the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by

To determine whether a decline in value is related to credit loss, the Company evaluates, among other factors: the extent to which the fair value is less than the amortized cost basis, changes to the rating of the security by a rating agency and any adverse conditions specifically related to an issuer of a security or its industry. Unrealized gains and losses on marketable securities are presented net of tax.

The Company classifies its commercial paper, corporate debt securities, certificates of deposit and U.S. and non-U.S. government treasury securities within Level 2 because they are valued using inputs other than quoted prices that are directly or indirectly observable in the market, including readily available pricing sources for the identical underlying security which may not be actively traded. In addition to its cash equivalents and marketable securities, the Company measures the fair value of its outstanding convertible senior notes on a quarterly basis for disclosure purposes. The Company considers the fair value of the convertible senior notes to be a Level 2 measurement due to limited trading activity of the convertible senior notes.

Convertible Senior Notes

Convertible Senior Notes	6 Months Ended

Debt Disclosure [Abstract]
Convertible Senior Notes	Convertible Senior Notes On June 2, 2020, the Company issued $747.5 million aggregate principal amount of 0.125% convertible senior notes due 2025 (the “2025 Notes”) in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (“Securities Act”). The total net proceeds from the sale of the 2025 Notes, after deducting the initial purchasers’ discounts and debt issuance costs, were approximately $730.2 million. The 2025 Notes bear interest at a rate of 0.125% per year, payable semiannually in arrears on June 15 and December 15 of each year, beginning on December 15, 2020. The 2025 Notes will mature on June 15, 2025, unless earlier converted, redeemed or repurchased. Holders may convert their notes at their option at any time prior to the close of business on the business day immediately preceding March 15, 2025 only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 2020 (and only during such calendar quarter), if the last reported sale price of the Company’s Class A common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period (the "Measurement Period") in which the trading price per $1,000 principal amount of 2025 Notes for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price of the Company’s Class A common stock and the conversion rate on each such trading day; (3) if the Company calls such 2025 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events, as set forth in the indenture governing the 2025 Notes (“the Indenture”). On or after March 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their notes, in integral multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. The conversion rate for the 2025 Notes is initially 10.8338 shares of Class A common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $92.30 per share of Class A common stock), subject to adjustment as set forth in the Indenture. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at the Company’s election. If the Company satisfies its conversion obligation solely in cash or through payment and delivery, as the case may be, of a combination of cash and shares of Class A common stock, the amount of cash and shares of Class A common stock, if any, due upon conversion will be based on a daily conversion value calculated on a proportionate basis for each trading day in a 30 trading day observation period as described in the Indenture. In addition, if specific corporate events occur prior to the applicable maturity date, or if the Company elects to redeem the 2025 Notes, the Company will increase the conversion rate for a holder who elects to convert their notes in connection with such a corporate event or redemption in certain circumstances. During the three months ended June 30, 2022, the conditional conversion feature of the 2025 Notes was not triggered as the last reported sale price of the Company's Class A common stock was not greater than or equal to 130% of the conversion price for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the quarter ended June 30, 2022. Therefore the 2025 Notes are not convertible, in whole or in part, at the option of the holders between July 1, 2022 through September 30, 2022. Whether the 2025 Notes will be convertible following such period will depend on the continued satisfaction of this condition or another conversion condition in the future. When a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. As of June 30, 2022, the Company has received an immaterial amount of conversion notices from the holders and the 2025 Notes were classified as long-term debt on the Company's condensed consolidated balance sheet. The Company may not redeem the 2025 Notes prior to June 20, 2023. On or after June 20, 2023, and prior to the 31st scheduled trading day immediately preceding the maturity date, the Company may redeem for cash all or any portion of the 2025 Notes, at its option, if the last reported sale price of its Class A common stock was at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides a notice of redemption at a redemption price equal to 100% of the principal amount of the 2025 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. In accounting for the issuance of the 2025 Notes, the 2025 Notes were separated into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of similar liabilities that do not have associated convertible features. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the par value of the respective 2025 Notes. This difference represents the debt discount that is amortized to interest expense over the contractual terms of the 2025 Notes using the effective interest rate method. The carrying amount of the equity component representing the conversion option was $177.2 million. The equity component was recorded in additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. In accounting for the debt issuance costs of $17.3 million related to the 2025 Notes, the Company allocated the total amount incurred to the liability and equity components of the 2025 Notes in the same proportion as the allocation of the proceeds. Issuance costs attributable to the liability component were $13.2 million and will be amortized, along with the debt discount to interest expense over the contractual term of the 2025 Notes at an effective interest rate of 5.97%. Issuance costs attributable to the equity component were $4.1 million and are netted against the equity component in additional paid-in capital. On January 1, 2021 the Company adopted ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU No. 2020-06”) . As a result of the adoption, the debt conversion option of $177.2 million and debt issuance costs of $4.1 million previously attributable to the equity component are no longer presented in equity. Similarly, the debt discount, that is equal to the carrying value of the embedded conversion feature upon issuance, is no longer amortized into income as interest expense over the life of the instrument. This resulted in a $16.8 million decrease to the opening balance of accumulated deficit, a $173.1 million decrease to the opening balance of additional paid-in capital and a $156.3 million increase to the opening balance of convertible senior notes, net on the condensed consolidated balance sheet. The net carrying amount of the liability component of the 2025 Notes was as follows (in thousands): June 30, December 31, Convertible senior notes, net: Principal $ 747,496 $ 747,500 Unamortized debt issuance costs (10,336) (12,018) Net carrying amount $ 737,160 $ 735,482 As of June 30, 2022, the total estimated fair value of the 2025 Notes was approximately $940.9 million. The fair value was determined based on the closing trading price per $100 of the 2025 Notes as of the last day of trading for the period. The fair value of the 2025 Notes is primarily affected by the trading price of the Company’s Class A common stock and market interest rates. The following table sets forth the interest expense related to the 2025 Notes (in thousands): Three Months Ended Six Months Ended 2022 2021 2022 2021 Contractual interest expense $ 233 $ 233 $ 467 $ 467 Amortization of issuance costs 842 837 1,682 1,672 Total $ 1,075 $ 1,070 $ 2,149 $ 2,139 Capped Calls In connection with the pricing of the 2025 Notes, the Company entered into privately negotiated capped call transactions with certain counterparties (“Capped Calls”). The Capped Calls each have an initial strike price of approximately $92.30 per share, subject to certain adjustments, which corresponds to the initial conversion price of the 2025 Notes. The Capped Calls have initial cap prices of $151.04 per share, subject to certain adjustments. The Capped Calls are expected to partially offset the potential dilution to the Company’s Class A common stock upon any conversion of the 2025 Notes, with such offset subject to a cap based on the cap price. The Capped Calls cover, subject to anti-dilution adjustments, approximately 8.1 million shares of the Company’s Class A common stock. For accounting purposes, the Capped Calls are separate transactions, and not part of the 2025 Notes. As these transactions meet certain accounting criteria, the Capped Calls are recorded in stockholders' equity and are not accounted for as derivatives. The cost of $89.6 million incurred to purchase the Capped Calls was recorded as a reduction to additional paid-in capital and will not be remeasured.

Leases [Abstract]
Leases	Leases The Company has entered into various non-cancelable operating leases for its facilities expiring between 2022 and 2030. Certain lease agreements contain an option for the Company to renew a lease for a term of up to five years or an option to terminate a lease early within one year. The Company considers these options, which may be elected at the Company’s sole discretion, in determining the lease term on a lease-by-lease basis.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Geographical Information Revenue by location is determined by the billing address of the customer. The following table sets forth revenue by geographic area (in thousands): Three Months Ended Six Months Ended 2022 2021 2022 2021 North America $ 291,159 $ 168,196 $ 551,021 $ 311,085 International 114,979 65,353 218,147 121,013 Total $ 406,138 $ 233,549 $ 769,168 $ 432,098 Deferred Revenue and Remaining Performance Obligations Certain of the Company’s customers pay in advance of satisfaction of performance obligations and other customers with monthly contract terms are billed in arrears on a monthly basis. The Company records contract liabilities to deferred revenue when customers are billed or when the Company receives customer payments in advance of the performance obligations being satisfied on the Company’s contracts. Revenue recognized during the three months ended June 30, 2022 and 2021, which was included in the deferred revenue balances at the beginning of each such period, was $198.3 million and $108.4 million, respectively. Revenue recognized during the six months ended June 30, 2022 and 2021 that was included in the deferred revenue balances at the beginning of each such period was $279.9 million and $158.8 million, respectively. Remaining performance obligations represent the aggregate amount of the transaction price in contracts allocated to performance obligations not delivered, or partially undelivered, as of the end of the reporting period. Remaining performance obligations include unearned revenue, multi-year contracts with future installment payments and certain unfulfilled orders against accepted customer contracts at the end of any given period. As of June 30, 2022 and December 31, 2021, the aggregate transaction price allocated to remaining performance obligations was $881.4 million and $815.0 million, respectively. There is uncertainty in the timing of revenues associated with the Company’s drawdown contracts, as future revenue can often vary significantly from past revenue. However, the Company expects to recognize substantially all of the remaining performance obligations over the next 24 months. Accounts Receivable Accounts receivable deemed uncollectible are charged against the allowance for credit losses when identified. During the six months ended June 30, 2022 and 2021, the Company charged $0.9 million and $0.7 million, respectively, of accounts receivable deemed uncollectible against the allowance for credit losses. Unbilled accounts receivable represents revenue recognized on contracts for which billings have not yet been presented to customers because the amounts were earned but not contractually billable as of the balance sheet date. The unbilled accounts receivable balance is due within one year. As of June 30, 2022 and December 31, 2021, unbilled accounts receivable of approximately $58.2 million and $44.2 million, respectively, was included in accounts receivable on the Company’s condensed consolidated balance sheets. Deferred Contract Costs Sales commissions earned by the Company’s sales force are considered incremental and recoverable costs of obtaining a contract with a customer. These costs are deferred and then amortized over a period of benefit which is determined to be four years. Amounts expected to be recognized within one year of the balance sheet date are recorded as deferred contract costs, current; the remaining portion is recorded as deferred contract costs, non-current, in the condensed consolidated balance sheets. Deferred contract costs on the Company’s condensed consolidated balance sheets were $74.2 million and $65.3 million as of June 30, 2022 and December 31, 2021, respectively. Amortization expense was $6.6 million and $4.1 million for the three months ended June 30, 2022 and 2021, respectively, and was $12.6 million and $7.9 million for the six months ended June 30, 2022 and 2021, respectively.

Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity Class A and Class B Common Stock The Company has two classes of common stock, Class A and Class B. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. Each share of Class A common stock is entitled to one vote per share and each share of Class B common stock is entitled to ten votes per share. Shares of Class B common stock may be converted into Class A common stock at any time at the option of the stockholder, and are automatically converted to Class A common stock upon sale or transfer, subject to certain limited exceptions. During the three and six months ended June 30, 2022, 6,284,309 shares and 24,393,510 shares of Class B common stock were converted into Class A common stock, respectively. As of June 30, 2022, the Company had authorized 2,000,000,000 shares of Class A common stock and 310,000,000 shares of Class B common stock, each at a par value per share of $0.00001, of which 290,783,440 shares of Class A common stock and 25,632,342 shares of Class B common stock were issued and outstanding. Equity Incentive Plans The Company has two equity incentive plans, the 2012 Equity Incentive Plan (the “2012 Plan”) and the 2019 Equity Incentive Plan (the “2019 Plan”). In connection with the Company's initial public offering of Class A common stock (the "IPO"), the Company ceased granting awards under the 2012 Plan, and all shares that remained available for issuance under the 2012 Plan at that time were transferred to the 2019 Plan. Additionally, as of June 30, 2022, there were 19,567,562 shares of Class A common stock issuable upon conversion of Class B common stock underlying options outstanding under the 2012 Plan. Under the 2019 Plan, the Board and any other committee or subcommittee of the Board may grant stock options, stock appreciation rights, restricted stock awards, restricted stock units (“RSUs”) and performance stock units ("PSUs") and other awards, each equity award valued or based on the Company’s Class A common stock, to employees, directors, consultants and advisors of the Company. As of June 30, 2022, there were 67,352,167 shares available for grant under the 2019 Plan. Stock Options The following table summarizes the Company’s stock option activity and weighted-average exercise prices: Number Of Weighted- Weighted- Aggregate Balance outstanding—December 31, 2021 21,372,561 $ 3.31 5.5 $ 3,735,819 Options granted — — Options exercised (1,673,753) 3.83 Options forfeited or expired (101,980) 5.94 Balance outstanding—June 30, 2022 19,596,828 $ 3.26 4.9 $ 1,802,576 Ending Exercisable—June 30, 2022 16,977,114 $ 2.37 4.6 $ 1,576,610 As of June 30, 2022, there were 29,266 shares of Class A common stock and 19,567,562 shares of Class B common stock issuable upon the exercise of options outstanding. As of December 31, 2021, there were 31,671 shares of Class A common stock and 21,340,890 shares of Class B common stock issuable upon the exercise of options outstanding. Total compensation cost related to unvested awards not yet recognized was approximately $20.0 million and $31.6 million as of June 30, 2022 and December 31, 2021, respectively. The weighted-average period over which this compensation cost related to unvested employee awards will be recognized is 0.9 years and 1.3 years as of June 30, 2022 and December 31, 2021, respectively. There were no options granted during the six months ended June 30, 2022 and 2021. The Company received approximately $6.5 million and $6.2 million in cash proceeds from options exercised during the six months ended June 30, 2022 and 2021, respectively. The intrinsic value of options exercised during the six months ended June 30, 2022 and 2021 was approximately $217.0 million and $229.6 million, respectively. The aggregate fair value of options vested during the six months ended June 30, 2022 and 2021 was $12.7 million and $14.5 million, respectively. Common stock purchased pursuant to an early exercise of stock options is not deemed to be outstanding for accounting purposes until those shares vest. The consideration received for an exercise of an option is considered to be a deposit of the exercise price and the related dollar amount is recorded as a liability. The shares issued upon the early exercise of these unvested stock option awards, which are reflected as exercises in the table above, are considered to be legally issued and outstanding on the date of exercise. Upon termination of service, the Company may repurchase unvested shares acquired through early exercise of stock options at a price equal to the price per share paid upon the exercise of such options. The Company has no liability recorded related to early exercises of options as of June 30, 2022. As of December 31, 2021, the Company had recorded liabilities related to early exercises of options for 31,500 shares of Class B common stock. Restricted Stock Units, Restricted Stock Awards and Performance Stock Units The following table summarizes the activity for the Company’s unvested RSUs and PSUs: Shares Weighted- Balance—December 31, 2021 8,081,269 $ 101.21 Awarded 3,119,713 124.03 Vested (1,039,058) 74.93 Forfeited/canceled (422,308) 103.66 Unvested and outstanding—June 30, 2022 9,739,616 $ 111.22 The Company granted 244,445, 96,210, 117,538, 245,761, 98,593, and 191,809 restricted shares of Class A common stock in November 2019, June 2020, February 2021, April 2021, December 2021, and June 2022, respectively, in connection with acquisitions which are subject to service-based vesting conditions over approximately four years from the respective grant dates. Total compensation cost related to unvested RSUs, PSUs and restricted shares of common stock not yet recognized was approximately $976.8 million and $773.6 million as of June 30, 2022 and December 31, 2021, respectively. The weighted-average period over which this compensation cost related to unvested RSUs, PSUs and restricted shares will be recognized is 2.9 years and 3.1 years as of June 30, 2022 and December 31, 2021, respectively. Employee Stock Purchase Plan In September 2019, the Board adopted and approved the 2019 Employee Stock Purchase Plan (the “ESPP”), which became effective on the date of the final prospectus for the IPO. The ESPP is implemented through a series of offerings under which eligible employees are granted purchase rights to purchase shares of the Company’s Class A common stock on specified dates during such offerings. Under the ESPP, the Company may specify offerings with durations of not more than 27 months, and may specify shorter purchase periods within each offering. On each purchase date, eligible employees will purchase the shares at a price per share equal to 85% of the lesser of (1) the fair market value of the Company’s Class A common stock on the first trading day of the offering period, or (2) the fair market value of the Company’s Class A common stock on the purchase date, as defined in the ESPP. The Company recognized $2.5 million and $4.7 million of stock-based compensation expense related to the ESPP during the three and six months ended June 30, 2022, respectively. As of June 30, 2022, $4.7 million has been withheld on behalf of employees for a future purchase under the ESPP due to the timing of payroll deductions. During the three months ended June 30, 2022, the Company issued 146,515 shares of Class A common stock under the ESPP. As of June 30, 2022, 14,976,951 shares of Class A common stock remain available for grant under the ESPP. Stock-Based Compensation The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options on the date of grant. The Company recognizes and measures compensation expense for all stock-based payment awards granted to employees, directors and nonemployees based on the fair value of the awards on the date of grant. The determination of the grant date fair value using an option-pricing model is affected by the estimated fair value of the Company’s common stock as well as assumptions regarding a number of other complex and subjective variables. These variables include expected stock price volatility over the expected term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate for the expected term of the award and expected dividends. The fair value of RSUs and PSUs is determined by the closing price on the date of grant of the Company’s Class A common stock, as reported on the Nasdaq Global Select Market. The Company estimates the fair value of the rights to acquire stock under the ESPP using the Black-Scholes option-pricing model. Stock-based compensation for stock options and RSUs is recognized on a straight-line basis over the requisite service period and account for forfeitures as they occur. Stock-based compensation for PSUs is amortized under the accelerated attribution method and may be adjusted over the vesting period based on interim estimates of performance against pre-set objectives. PSUs will vest upon achievement of specified performance targets and subject to continuous service through the applicable vesting dates. The compensation cost is recognized over the requisite service period when it is considered probable that the performance condition will be satisfied and account for forfeitures as they occur. Stock-based compensation expense was included in the condensed consolidated statement of operations as follows (in thousands): Three Months Ended Six Months Ended 2022 2021 2022 2021 Cost of revenue $ 2,355 $ 829 $ 4,008 $ 1,530 Research and development 53,309 21,639 98,005 37,708 Sales and marketing 17,590 6,606 32,185 13,616 General and administrative 9,145 5,441 15,085 10,522 Stock-based compensation, net of amounts capitalized 82,399 34,515 149,283 63,376 Capitalized stock-based compensation expense 3,334 2,059 6,840 4,212 Total stock-based compensation expense $ 85,733 $ 36,574 $ 156,123 $ 67,588

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company has an effective tax rate of (44,254.5)% and 3.1% for the three months ended June 30, 2022 and 2021, respectively . The Company has incurred U.S. operating losses and has minimal profits in its foreign jurisdictions during the quarter. The Company has applied ASC 740, Income Taxes , and has determined that it has uncertain positions that would result in a tax reserve deemed immaterial for each of the six months ended June 30, 2022 and 2021. The Company’s policy is to recognize interest and penalties related to uncertain tax positions in income tax expense. The Company is subject to U.S. federal tax authority, U.S . state tax authority and foreign tax authority examinations. The Company has evaluated the available evidence supporting the realization of its deferred tax assets, including the amount and timing of future taxable income, and has determined that it is more likely than not that its net deferred tax assets will not be realized in the United States. Due to uncertainties surrounding the realization of the deferred tax assets, the Company recorded a full valuation allowance against substantially all of its net deferred tax assets. When the Company determines that it will be able to realize some portion or all of its deferred tax assets, an adjustment to its valuation allowance on its deferred tax assets would have the effect of increasing net income in the period such determination is made.

Earnings Per Share [Abstract]
Net (Loss) Income Per Share	Net (Loss) Income Per Share Basic and diluted net (loss) income per common share is presented in conformity with the two-class method required for participating securities. Immediately prior to the consummation of the Company’s IPO in September 2019, all outstanding shares of convertible preferred stock and common stock were converted into shares of Class B common stock. As a result, Class A and Class B common stock are the only outstanding shares of capital stock of the Company. Basic and diluted net (loss) income per share is computed using the weighted-average number of shares of common stock outstanding during the period. The undistributed earnings are allocated based on the contractual participation rights of the Class A and Class B common stock as if the earnings for the year have been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis. Further, as the conversion of Class B common stock is assumed in the computation of the diluted net (loss) income per share of Class A common stock, the undistributed earnings are equal to net (loss) income for that computation. The following table presents the calculation of basic and diluted net (loss) income per share (in thousands, except per share data): Three Months Ended Six Months Ended 2022 2021 2022 2021 Basic net (loss) income per share: Class A Class B Class A Class B Class A Class B Class A Class B Numerator: Net (loss) income $ (4,421) $ (458) $ (7,163) $ (2,199) $ 4,281 $ 578 $ (16,777) $ (5,653) Denominator: Weighted-average shares used in calculating net income (loss) per share, basic 285,265 29,530 235,671 72,348 276,779 37,351 229,652 77,380 Basic net (loss) income per share $ (0.02) $ (0.02) $ (0.03) $ (0.03) $ 0.02 $ 0.02 $ (0.07) $ (0.07) Diluted net (loss) income per share: Numerator: Allocation of distributed net (loss) income for basic computation $ (4,421) $ (458) $ (7,163) $ (2,199) $ 4,281 $ 578 $ (16,777) $ (5,653) Reallocation of undistributed net (loss) income as a result of conversion of Class B to Class A shares (458) — (2,199) — 578 — (5,653) — Allocation of undistributed (loss) income $ (4,879) $ (458) $ (9,362) $ (2,199) $ 4,859 $ 578 $ (22,430) $ (5,653) Denominator: Number of shares used in basic calculation 285,265 29,530 235,671 72,348 276,779 37,351 229,652 77,380 Weighted-average effect of diluted securities: Conversion of Class B to Class A common shares outstanding 29,530 — 72,348 — 37,351 — 77,380 — Employee stock options — — — — 19,602 — — — Employee stock purchase plan — — — — 32 — — — Unvested early exercises — — — — 5 — — — Restricted stock units — — — — 2,955 — — — Unvested restricted stock in connection with acquisition — — — — 622 — — — Shares issuable upon conversion of the convertible senior notes — — — — 8,098 — — — Number of shares used in diluted calculation 314,795 29,530 308,019 72,348 345,444 37,351 307,032 77,380 Diluted net (loss) income per share $ (0.02) $ (0.02) $ (0.03) $ (0.03) $ 0.01 $ 0.02 $ (0.07) $ (0.07) Potentially dilutive securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows (in thousands): As of June 30, 2022 2021 Shares subject to outstanding stock options and RSUs 2,127 31,118 Unvested early exercised stock options and restricted shares of common stock — 959 Shares subject to the employee stock purchase plan — 177 Shares issuable upon conversion of the convertible senior notes — 8,098 Total 2,127 40,352 ASU No. 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share when the instruments may be settled in cash or shares.
