Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Nature of Operations	ORGANIZATION AND NATURE OF OPERATIONS Nasdaq is a global technology company serving the capital markets and other industries. Our diverse offerings of data, analytics, software and services enable clients to optimize and execute their business vision with confidence. We manage, operate and provide our products and services in four business segments: Market Technology, Investment Intelligence, Corporate Platforms, and Market Services. Market Technology Our Market Technology segment is a leading global technology solutions provider and partner to exchanges, clearing organizations, central securities depositories, regulators, banks, brokers, buy-side firms and corporate businesses. Our solutions are utilized by leading markets in the U.S., Europe and Asia as well as emerging markets in the Middle East, Latin America, and Africa. The Market Technology segment includes our Anti Financial Crime Technology business and our Marketplace Infrastructure Technology business. Our Anti Financial Crime Technology business includes Nasdaq Trade Surveillance, a SaaS solution designed for brokers and other market participants, and Market Surveillance, a solution for market infrastructure operators. Both solutions are designed to assist in complying with market rules, regulations and internal market surveillance policies. Our Verafin business is a SaaS anti-financial crime management solution that offers a cloud-based platform to help detect, investigate, and report money laundering and fraud. Verafin also has targeted sanctions screening solutions that help banks manage sanctions, including those imposed against Russia. Verafin is further expanding this product to detect new means of evasion-based typologies. In the first quarter of 2022, we reclassified Nasdaq Risk Platform revenues from Anti Financial Crime Technology to Marketplace Infrastructure Technology. Total Market Technology segment revenues were unchanged. Our Marketplace Infrastructure Technology business powers market infrastructure operators and new market clients globally and handles a wide array of assets, including but not limited to cash equities, equity derivatives, currencies, various interest-bearing securities, commodities, energy products and digital currencies. Our solutions can also be used in the creation of new asset classes, and non-capital markets customers, including those in insurance liabilities securitization, cryptocurrencies and sports wagering. Investment Intelligence Our Investment Intelligence segment includes our Market Data, Index and Analytics businesses. Our Market Data business sells and distributes historical and real-time market data to the sell-side, the institutional investing community, retail online brokers, proprietary trading shops, other venues, internet portals and data distributors. Our market data products can enhance transparency of market activity within our exchanges and provide critical information to professional and non-professional investors globally. Additionally, our Nasdaq Cloud Data Service provided on our Data Link data dissemination platform provides a flexible and efficient method of delivery for real-time exchange data and other financial information. Our Index business develops and licenses Nasdaq-branded indexes. We also license cash-settled options, futures and options on futures on our indexes. As of June 30, 2022, 374 ETPs listed on 29 exchanges in over 20 countries tracked a Nasdaq index and accounted for $321 billion in AUM. Our Analytics business provides asset managers, investment consultants and institutional asset owners with information and analytics to make data-driven investment decisions and deploy their resources more productively. We also provide liquidity solutions for private funds. Through our eVestment offerings, we provide a suite of cloud-based solutions that help institutional investors and consultants conduct pre-investment due diligence, and monitor their portfolios post-investment. The eVestment platform also enables asset managers to efficiently distribute information about their firms and funds to asset owners and consultants worldwide. Through the Solovis platform, endowments, foundations, pensions and family offices transform how they collect and aggregate investment data, analyze portfolio performance, model and predict future outcomes, and share meaningful portfolio insights with key stakeholders. The Nasdaq Fund Network and Nasdaq Data Link are additional platforms in our suite of investment data analytics offerings and data management tools. The Nasdaq Fund Network offers fund data services that deliver transparency to investable products through the collection and dissemination of performance, net asset value, valuation, and strategy-level reference data. Nasdaq Data Link strengthens our position as a leading source for financial, economic, and alternative datasets. For investment management firms, investment banks and other investors, the platform powers data-driven decision-making for users across the globe via universal application programming interfaces, and provides for highly efficient data discovery and delivery. Corporate Platforms Our Corporate Platforms segment includes our Listing Services and IR & ESG Services businesses. These businesses deliver critical capital market and ESG solutions across the lifecycle of public and private companies. Our Listing Services business includes our U.S. and European Listing Services businesses. We operate a variety of listing platforms around the world to provide multiple global capital raising solutions for public companies. Our main listing markets are The Nasdaq Stock Market and the Nasdaq Nordic and Nasdaq Baltic exchanges. Through Nasdaq First North, our Nordic and Baltic operations also offer alternative marketplaces for smaller companies and growth companies. In July 2021, we contributed our NPM business, which was included in our Listing Services business, to a standalone, independent company, of which we own the largest minority interest, together with a consortium of third-party financial institutions. The NPM business provides liquidity solutions for private companies to enable employees, investors, and companies to execute transactions. As of June 30, 2022, there were 4,269 total listings on The Nasdaq Stock Market, including 465 ETPs. The combined market capitalization was approximately $20.3 trillion. In Europe, the Nasdaq Nordic and Nasdaq Baltic exchanges, together with Nasdaq First North, were home to 1,260 listed companies with a combined market capitalization of approximately $1.8 trillion. We also operate a U.S. Corporate Bond exchange for the listing of corporate bonds. This exchange operates pursuant to The Nasdaq Stock Market exchange license and is powered by the NFF. As of June 30, 2022, 102 corporate bonds were listed on the Corporate Bond exchange. We continue to develop the Nasdaq Sustainable Bond Network, a platform for increased transparency in the global sustainable bond markets. Our IR & ESG Services include our portfolio of products and services that support corporations’ investor relations and ESG functions. Our clients include both public and private companies and organizations. Our public company clients can be companies listed on our exchanges or other U.S. and global exchanges. Our private company clients include a diverse group of organizations ranging from family owned companies, government organizations, law firms, privately held entities, various non-profit organizations to hospitals and health care systems. We help organizations enhance their ability to understand and expand their global shareholder base, improve corporate governance, and navigate the evolving ESG landscape through our suite of advanced technology, analytics, reporting and consultative services. In June 2022, we acquired Metrio Software Inc., or Metrio, a provider of ESG data collection, analytics and reporting services based in Montreal, Canada. We plan to integrate Metrio’s SaaS platform into our suite of ESG solutions. Market Services Our Market Services segment includes our Equity Derivative Trading and Clearing, Cash Equity Trading, FICC and Trade Management Services businesses. We operate multiple exchanges and other marketplace facilities across several asset classes, including derivatives, commodities, cash equity, debt, structured products and ETPs. In addition, in certain countries where we operate exchanges, we also provide clearing, settlement and central depository services. In June 2022, we completed the wind-down of our Nordic broker services business. Our transaction-based platforms provide market participants with the ability to access, process, display and integrate orders and quotes. The platforms allow the routing and execution of buy and sell orders as well as the reporting of transactions, providing fee-based revenues. In the U.S., we operate six options exchanges and three cash equity exchanges. The Nasdaq Stock Market, the largest of our cash equities exchanges, is the largest single venue of liquidity for trading U.S.-listed cash equities. In Canada, we operate an exchange with three independent markets for the trading of Canadian-listed securities: Nasdaq Canada CXC, Nasdaq Canada CX2 and Nasdaq Canada CXD. In Europe, we operate exchanges in Stockholm (Sweden), Copenhagen (Denmark), Helsinki (Finland), and Reykjavik (Iceland), as well as the clearing operations of Nasdaq Clearing, as Nasdaq Nordic. We also operate exchanges in Tallinn (Estonia), Riga (Latvia) and Vilnius (Lithuania) as Nasdaq Baltic. Collectively, Nasdaq Nordic and Nasdaq Baltic offer trading in cash equities, depository receipts, warrants, convertibles, rights, fund units and ETFs, as well as trading and clearing of equity derivatives, fixed income and commodity products. We also own a majority stake in Puro.earth, a Finnish-based leading marketplace for carbon removal. Nasdaq Fixed Income provides a wide range of products and services, such as trading and clearing, for fixed income products in Sweden, Denmark, Finland, Iceland, Estonia, Lithuania and Latvia. Nasdaq Commodities is the brand name for Nasdaq’s European commodity-related products and services. Nasdaq Commodities’ offerings include derivatives in power, natural gas and carbon emission markets, seafood, electricity certificates and clearing services. These products are listed on Nasdaq Oslo ASA, except for seafood, which is listed on Fishpool, a third-party platform. In June 2021, we sold our U.S. Fixed Income business, which included an electronic platform for the trading of U.S. Treasuries. See “2021 Divestiture” of Note 4, “Acquisitions and Divestiture,” for further discussion.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION The condensed consolidated financial statements are prepared in accordance with U.S. GAAP and include the accounts of Nasdaq, its wholly-owned subsidiaries and other entities in which Nasdaq has a controlling financial interest. When we do not have a controlling interest in an entity, but exercise significant influence over the entity’s operating and financial policies, such investment is accounted for under the equity method of accounting. We recognize our share of earnings or losses of an equity method investee based on our ownership percentage. See “Equity Method Investments,” of Note 6, “Investments,” for further discussion of our equity method investments. The accompanying condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results. These adjustments are of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation. As permitted under U.S. GAAP, certain footnotes or other financial information can be condensed or omitted in the interim condensed consolidated financial statements. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in Nasdaq’s Form 10-K. The year-end condensed balance sheet data was derived from the audited financial statements, but does not include all disclosures required by U.S. GAAP. Certain prior year amounts have been reclassified to conform to the current year presentation. During the fourth quarter of 2021, we began adjusting the presentation of cash and cash equivalents held within default funds and margin deposits on the condensed consolidated statement of cash flows from operating activities, to present them as restricted cash and cash equivalents with the associated changes being included within cash flows from investing and financing activities. These balances cannot be used to satisfy operating or other liabilities. See Note 14, “Clearing Operations,” for further discussion of the default funds and margin deposits. Prior period amounts have also been adjusted to conform to current period presentation. This immaterial adjustment had no impact on our previously reported Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Income, or Condensed Consolidated Statements of Comprehensive Income. The table below presents a summary of the as reported and adjusted amounts relating to the Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2021. Six Months Ended June 30, 2021 As Reported Adjustment Adjusted (in millions) Net cash provided by operating activities $ 467 $ — $ 467 Net cash used in investing activities (2,435) (90) (2,525) Net cash used in financing activities (380) (229) (609) Effect of exchange rate changes on cash, cash equivalents, restricted cash and cash equivalents (4) (104) (108) Net decrease in cash, cash equivalents, restricted cash and cash equivalents (2,352) (423) (2,775) Cash, cash equivalents, restricted cash and cash equivalents at beginning of period 2,782 3,197 5,979 Cash, cash equivalents, restricted cash and cash equivalents at end of period $ 430 $ 2,774 $ 3,204 Reconciliation of Cash, Cash Equivalents and Restricted Cash and Cash Equivalents Cash and cash equivalents $ 390 $ — $ 390 Restricted cash and cash equivalents 40 — 40 Restricted cash and cash equivalents (Default funds and margin deposits) — 2,774 2,774 Total $ 430 $ 2,774 $ 3,204 Accounting Estimates In preparing our condensed consolidated financial statements, we make assumptions, judgments and estimates that can have a significant impact on our revenue, operating income and net income, as well as on the value of certain assets and liabilities in our condensed consolidated balance sheets. At least quarterly, we evaluate our assumptions, judgments and estimates, and make changes as deemed necessary. Subsequent Event We have evaluated subsequent events through the issuance date of this Quarterly Report on Form 10-Q. In July 2022, we amended and restated our certificate of incorporation to increase our authorized shares to 930,000,000, consisting of 30,000,000 shares of preferred stock, par value $0.01 per share and 900,000,000 shares of common stock, par value $0.01 per share, in order to effect a stock split in the form of a stock dividend. For discussion of our 3-for-1 stock split in the form of a stock dividend, see "Stock Split," of Note 11, “Nasdaq Stockholders' Equity.”

For the six months ended June 30, 2022 and 2021 approximately 69.8% and 72.0%, respectively, of Market Services revenues were recognized at a point in time and 30.2% and 28.0%, respectively, were recognized over time. Contract Balances Substantially all of our revenues are considered to be revenues from contracts with customers. The related accounts receivable balances are recorded in our Condensed Consolidated Balance Sheets as receivables, which are net of allowance for doubtful accounts of $15 million as of June 30, 2022 and $17 million as of December 31, 2021. The changes in the balance between periods were immaterial. We do not have obligations for warranties, returns or refunds to customers. For the majority of our contracts with customers, except for our marketplace infrastructure technology and listings services contracts, our performance obligations range from three months to three years and there is no significant variable consideration. Deferred revenue is the only significant contract asset or liability as of June 30, 2022 . Deferred revenue represents consideration received that is yet to be recognized as revenue for unsatisfied performance obligations. Deferred revenue primarily represents our contract liabilities related to our fees for Market Technology, Investment Intelligence, Annual and Initial Listings, and IR & ESG Services contracts. See Note 7, “Deferred Revenue,” for our discussion on deferred revenue balances, activity, and expected timing of recognition. We do not have a material amount of revenue recognized from performance obligations that were satisfied in prior periods. We do not provide disclosures about transaction price allocated to unsatisfied performance obligations if contract durations are less than one year. For our initial listings the transaction price allocated to remaining performance obligations is included in deferred revenue. For our Market Technology, Analytics, and IR & ESG contracts, the portion of transaction price allocated to unsatisfied performance obligations is presented in the table below. To the extent consideration has been received, unsatisfied performance obligations would be included in the table below as well as deferred revenue. The following table summarizes the amount of the transaction price allocated to performance obligations that are unsatisfied, for contract durations greater than one year, as of June 30, 2022: Market Technology Analytics IR & ESG Services Total (in millions) Remainder of 2022 $ 269 $ 34 $ 35 $ 338 2023 461 52 47 560 2024 218 27 17 262 2025 137 10 3 150 2026 84 7 — 91 2027+ 137 5 — 142 Total $ 1,306 $ 135 $ 102 $ 1,543 Deferred revenue represents consideration received that is yet to be recognized as revenue. The changes in our deferred revenue during the six months ended June 30, 2022 are reflected in the following table: Balance at December 31, 2021 Additions Revenue Recognized Adjustments Balance at June 30, 2022 (in millions) Market Technology $ 117 $ 87 $ (84) $ (5) $ 115 Investment Intelligence 106 82 (70) — 118 Corporate Platforms: Initial Listing 145 20 (30) (2) 133 Annual Listings 2 180 (1) (1) 180 IR & ESG Services 57 45 (39) (1) 62 Other 21 7 (6) (2) 20 Total $ 448 $ 421 $ (230) $ (11) $ 628 In the above table: • Additions primarily reflect deferred revenue billed in the current period, net of recognition. • Revenue recognized includes revenue recognized during the current period that was included in the beginning balance. • Adjustments reflect foreign currency translation adjustments. • Other primarily includes deferred revenue from non-U.S. listing of additional shares fees. Listing of additional shares fees are included in our Listing Services business. As of June 30, 2022, we estimate that our deferred revenue will be recognized in the following years: Fiscal year ended: 2022 2023 2024 2025 2026 2027+ Total (in millions) Market Technology $ 87 $ 27 $ 1 $ — $ — $ — $ 115 Investment Intelligence 87 31 — — — — 118 Corporate Platforms: Initial Listings 24 38 28 19 16 8 133 Annual Listings 180 — — — — — 180 IR & ESG Services 50 12 — — — — 62 Other 6 6 5 2 1 — 20 Total $ 434 $ 114 $ 34 $ 21 $ 17 $ 8 $ 628 In the above table, 2022 represents the remaining six months of 2022. The timing of recognition of deferred revenue related to certain marketplace infrastructure technology contracts is primarily dependent upon the completion of customization and any significant modifications made pursuant to existing market technology contracts. As such, as it relates to market technology revenues, the timing represents our best estimate.

Business Combination and Asset Acquisition [Abstract]
Acquisitions and Divestiture	ACQUISITIONS AND DIVESTITURE We completed the following acquisitions and divestiture in 2022 and 2021. Financial results of each transaction are included in our condensed consolidated financial statements from the date of each acquisition. 2022 Acquisition In June 2022, we acquired Metrio, a provider of ESG data collection, analytics and reporting services based in Montreal, Canada. We plan to integrate Metrio’s SaaS platform into our suite of ESG solutions. Metrio is part of our IR & ESG business in our Corporate Platforms segment. 2021 Divestiture In June 2021, we sold our U.S. Fixed Income business, which was part of our FICC business within our Market Services segment, to Tradeweb Markets Inc. We recognized a pre-tax gain on the sale of $84 million, net of disposal costs. The pre-tax gain was included in net gain on divestiture of business in the Condensed Consolidated Statements of Income. In connection with this sale, we issued approximately 6.2 million shares of Nasdaq common stock. Nasdaq used the proceeds from the sale, available tax benefits and working and clearing capital of this business, as well as other sources of cash, to repurchase shares of Nasdaq common stock to reduce the impact on earnings per share dilution from the sale. To facilitate these repurchases, in June 2021, the board of directors authorized an increase to the share repurchase program. These repurchases were completed during the second quarter of 2022. See “Share Repurchase Program,” of Note 11, “Nasdaq Stockholders' Equity,” for further discussion. 2021 Acquisition Acquisition of Verafin In February 2021, we completed the acquisition of Verafin, a SaaS technology provider of anti-financial crime management solutions that provides a cloud-based platform to help detect, investigate, and report money laundering and fraud, for an aggregate purchase price of $2.75 billion, subject to certain adjustments. The $2.75 billion purchase price includes a cash payment of $102 million, reflected in cash from operating activities in our Condensed Consolidated Statements of Cash Flows, the release of which is subject to certain employment-related conditions over three years following the closing of the transaction. This payment was recorded as a prepaid expense and is recorded in other current and non-current assets in our Condensed Consolidated Balance Sheets and will be amortized to merger and strategic initiatives expense on a straight-line basis over a three-year period. Verafin is part of our Market Technology segment. The amounts in the table below represent the final allocation of the purchase price. The allocation of the purchase price was subject to revision during the measurement period, a period not to exceed 12 months from the acquisition date. Adjustments to the provisional values, which may include tax and other estimates, during the measurement period are recorded in the reporting period in which the adjustment amounts are determined. In 2021, we recorded a measurement period adjustment of $9 million. This adjustment resulted in an increase to both total net liabilities acquired and goodwill. This adjustment did not result in an impact to our Condensed Consolidated Statements of Income. The allocation of the purchase price for Verafin was finalized in the first quarter of 2022. (in millions) Goodwill $ 1,882 Acquired Intangible Assets 815 Total Net Liabilities Acquired (46) Purchase Consideration $ 2,651 Intangible Assets The following table presents the details of acquired intangible assets for Verafin at the date of acquisition. Acquired intangible assets with finite lives are amortized using the straight-line method. Customer Relationships Technology Trade Name Total Acquired Intangible Assets Intangible asset value (in millions) $ 532 $ 246 $ 37 $ 815 Discount rate used 7.5 % 7.5 % 7.5 % Estimated average useful life 22 years 7 years 20 years Customer Relationships Customer relationships represent the non-contractual and contractual relationships with customers. Methodology Customer relationships were valued using the income approach, specifically an excess earnings method. The excess earnings method examines the economic returns contributed by the identified tangible and intangible assets of a company, and then isolates the excess return that is attributable to the intangible asset being valued. Discount Rate The discount rate used reflects the amount of risk associated with the hypothetical cash flows for the customer relationships relative to the overall business. In developing a discount rate for the customer relationships, we estimated a weighted-average cost of capital for the overall business and we utilized this rate as an input when discounting the cash flows. The resulting discounted cash flows were then tax-effected at the applicable statutory rate. For our acquisition of Verafin, a discounted tax amortization benefit was added to the fair value of the assets under the assumption that the customer relationships would be amortized for tax purposes over a period of 20 years. Estimated Useful Life We estimate the useful life based on the historical behavior of the customers and a parallel analysis of the customers using the excess earnings method. Technology As part of our acquisition of Verafin, we acquired developed technology. Methodology The developed technology was valued using the income approach, specifically the relief-from-royalty method, or RFRM. The RFRM is used to estimate the cost savings that accrue to the owner of an intangible asset who would otherwise have to pay royalties or license fees on revenues earned through the use of the asset. The royalty rate is applied to the projected revenue over the expected remaining life of the intangible asset to estimate royalty savings. The net after-tax royalty savings are calculated for each year in the remaining economic life of the technology and discounted to present value. Discount Rate The discount rates used reflect the amount of risk associated with the hypothetical cash flows for the developed technology relative to the overall business as discussed above in “Customer Relationships.” Estimated Useful Life We have estimated the useful life of the Verafin technology to be 7 years. Trade Name As part of our acquisition of Verafin, we acquired a trade name. The trade name is recognized in the industry and carries a reputation for quality. As such, the reputation and positive recognition embodied in the trade name is a valuable asset to Nasdaq. Methodology The Verafin trade name was valued using the income approach, specifically the RFRM as discussed above in “Technology.” Discount Rate The discount rate used reflects the amount of risk associated with the hypothetical cash flows for the trade name relative to the overall business as discussed above in “Customer Relationships.” Estimated Useful Life We have estimated the useful life of the Verafin trade name to be 20 years and our intention is to continue to use it in the branding of products. Pro Forma Results and Acquisition-Related Costs The condensed consolidated financial statements for the three and six months ended June 30, 2022 and 2021 include the financial results of the above acquisitions from the date of the acquisitions. Pro forma financial results have not been presented since these acquisitions were not material to our financial results. Acquisition-related costs for the transactions described above were expensed as incurred and are included in merger and strategic initiatives expense in the Condensed Consolidated Statements of Income.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Acquired Intangible Assets	GOODWILL AND ACQUIRED INTANGIBLE ASSETS Goodwill The following table presents the changes in goodwill by business segment during the six months ended June 30, 2022: (in millions) Market Technology Balance at December 31, 2021 $ 2,171 Foreign currency translation adjustments (28) Balance at June 30, 2022 $ 2,143 Investment Intelligence Balance at December 31, 2021 $ 2,428 Foreign currency translation adjustments (107) Balance at June 30, 2022 $ 2,321 Corporate Platforms Balance at December 31, 2021 $ 469 Goodwill acquired 40 Foreign currency translation adjustments (22) Balance at June 30, 2022 $ 487 Market Services Balance at December 31, 2021 $ 3,365 Foreign currency translation adjustments (165) Balance at June 30, 2022 $ 3,200 Total Balance at December 31, 2021 $ 8,433 Goodwill acquired 40 Foreign currency translation adjustments (322) Balance at June 30, 2022 $ 8,151 As of June 30, 2022, the amount of goodwill that is expected to be deductible for tax purposes in future periods is $40 million. Goodwill represents the excess of purchase price over the value assigned to the net assets, including identifiable intangible assets, of a business acquired. Goodwill is allocated to our reporting units based on the assignment of the fair values of each reporting unit of the acquired company. We test goodwill for impairment at the reporting unit level annually, or in interim periods if certain events occur indicating that the carrying amount may be impaired, such as changes in the business climate, poor indicators of operating performance or the sale or disposition of a significant portion of a reporting unit. There was no impairment of goodwill for the three and six months ended June 30, 2022 and 2021; however, events such as prolonged economic weakness or unexpected significant declines in operating results of any of our reporting units or businesses, may result in goodwill impairment charges in the future. Acquired Intangible Assets The following table presents details of our total acquired intangible assets, both finite- and indefinite-lived: June 30, 2022 December 31, 2021 Finite-Lived Intangible Assets (in millions) Gross Amount Technology $ 305 $ 295 Customer relationships 2,009 2,050 Trade names and other 60 60 Foreign currency translation adjustment (199) (143) Total gross amount $ 2,175 $ 2,262 Accumulated Amortization Technology $ (75) $ (54) Customer relationships (727) (711) Trade names and other (14) (11) Foreign currency translation adjustment 111 81 Total accumulated amortization $ (705) $ (695) Net Amount Technology $ 230 $ 241 Customer relationships 1,282 1,339 Trade names and other 46 49 Foreign currency translation adjustment (88) (62) Total finite-lived intangible assets $ 1,470 $ 1,567 Indefinite-Lived Intangible Assets Exchange and clearing registrations $ 1,257 $ 1,257 Trade names 121 121 Licenses 52 52 Foreign currency translation adjustment (230) (184) Total indefinite-lived intangible assets $ 1,200 $ 1,246 Total intangible assets, net $ 2,670 $ 2,813 There was no impairment of indefinite-lived intangible assets for the three and six months ended June 30, 2022 and 2021.

Investments	INVESTMENTS The following table presents the details of our investments: June 30, 2022 December 31, 2021 (in millions) Financial investments $ 161 $ 208 Equity method investments $ 377 $ 363 Equity securities $ 63 $ 67 Financial Investments Financial investments are comprised of trading securities, primarily highly rated European government debt securities, of which $147 million as of June 30, 2022 and $162 million as of December 31, 2021, are assets primarily utilized to meet regulatory capital requirements, mainly for our clearing operations at Nasdaq Clearing. Equity Method Investments We record our estimated pro-rata share of earnings or losses each reporting period and record any dividends as a reduction in the investment balance. As of June 30, 2022 and 2021, our equity method investments primarily included our 40.0% equity interest in OCC. The carrying amounts of our equity method investments are included in other non-current assets in the Condensed Consolidated Balance Sheets. No material impairments were recorded for the three and six months end June 30, 2022 and 2021. Net income recognized from our equity interest in the earnings and losses of these equity method investments, primarily OCC, was $9 million for the three months ended June 30, 2022, $27 million for the three months ended June 30, 2021, $15 million for the six months ended June 30, 2022 and $84 million for the six months ended June 30, 2021. For the three and six months ended June 30, 2022, lower equity interest in the earnings of OCC, as compared to 2021, was primarily driven by a reduction in the clearing fee rate that OCC charges its customers, partially offset by elevated U.S. industry trading volumes. Equity Securities The carrying amounts of our equity securities are included in other non-current assets in the Condensed Consolidated Balance Sheets. We elected the measurement alternative for substantially all of our equity securities as they do not have a readily determinable fair value. No material adjustments were made to the carrying value of our equity securities for the three and six months ended June 30, 2022 and 2021. As of June 30, 2022 and December 31, 2021 , our equity securities primarily represent various strategic investments made through our corporate venture program as well as investments acquired through various acquisitions.

Debt obligations	DEBT OBLIGATIONS The following table presents the changes in the carrying amount of our debt obligations during the six months ended June 30, 2022: December 31, 2021 Additions Payments, Foreign Currency Translation and Accretion June 30, 2022 (in millions) Short-term debt: Commercial paper $ 420 $ 2,485 $ (2,484) $ 421 2022 Notes 598 — 1 599 2024 Notes 499 — (499) — Total short-term debt $ 1,517 $ 2,485 $ (2,982) $ 1,020 Long-term debt - senior unsecured notes: 2026 Notes 498 — — 498 2029 Notes 676 — (53) 623 2030 Notes 676 — (53) 623 2050 Notes 486 — — 486 2031 Notes 643 — 1 644 2040 Notes 644 — — 644 2033 Notes 694 — (54) 640 2052 Notes — 541 — 541 2020 Credit Facility (4) — 1 (3) Total long-term debt $ 4,313 $ 541 $ (158) $ 4,696 Total debt obligations $ 5,830 $ 3,026 $ (3,140) $ 5,716 In the table above, the 2024 Notes were reclassified to short-term debt as of March 31, 2022. The long-term debt senior unsecured notes in the table above, and discussion below, are listed based on their issuance date. Commercial Paper Program Our U.S. dollar commercial paper program is supported by our 2020 Credit Facility which provides liquidity support for the repayment of commercial paper issued through this program. See “2020 Credit Facility” below for further discussion. The effective interest rate of commercial paper issuances fluctuates as short term interest rates and demand fluctuate. The fluctuation of these rates may impact our interest expense. In January 2022, we issued commercial paper to partially fund our ASR agreement. See “ASR Agreement,” of Note 11, “Nasdaq Stockholders' Equity." As of June 30, 2022, we had $421 million outstanding under our commercial paper program. Senior Unsecured Notes Our 2022 and 2040 Notes were issued at par. All of our other outstanding senior unsecured notes were issued at a discount. As a result of the discount, the proceeds received from each issuance were less than the aggregate principal amount. As of June 30, 2022, the amounts in the table above reflect the aggregate principal amount, less the unamortized debt discount and the unamortized debt issuance costs, which are being accreted through interest expense over the life of the applicable notes. For our Euro denominated notes, the “Payments, Foreign Currency Translation and Accretion” column also includes the impact of foreign currency translation. Our senior unsecured notes are general unsecured obligations which rank equally with all of our existing and future unsubordinated obligations and are not guaranteed by any of our subsidiaries. The senior unsecured notes were issued under indentures that, among other things, limit our ability to consolidate, merge or sell all or substantially all of our assets, create liens, and enter into sale and leaseback transactions. The senior unsecured notes may be redeemed by Nasdaq at any time, subject to a make-whole amount. Upon a change of control triggering event (as defined in the various supplemental indentures governing the applicable notes), the terms require us to repurchase all or part of each holder’s notes for cash equal to 101% of the aggregate principal amount purchased plus accrued and unpaid interest, if any. Early Extinguishment of 2024 Notes In May 2014, Nasdaq issued the 2024 Notes, which paid interest semiannually at a rate of 4.25% per annum. In April 2022, we primarily used the net proceeds from the 2052 Notes to repay in full and redeem our 2024 Notes. For further discussion see “2052 Notes” below. In connection with the early extinguishment of the 2024 Notes, in April 2022 we recorded a pre-tax charge of $16 million, which primarily includes a make-whole redemption price premium. 2026 Notes In June 2016, Nasdaq issued the 2026 Notes, which pay interest semi-annually at a rate of 3.85% per annum until June 30, 2026. Such interest rate may vary with Nasdaq’s debt rating, to the extent Nasdaq is downgraded below investment grade, up to a rate not to exceed 5.85%. 2029 Notes In April 2019, Nasdaq issued the 2029 Notes, which pay interest annually at a rate of 1.75% per annum until March 28, 2029. Such interest rate may vary with Nasdaq’s debt rating, to the extent Nasdaq is downgraded below investment grade, up to a rate not to exceed 3.75%. The 2029 Notes have been designated as a hedge of our net investment in certain foreign subsidiaries to mitigate the foreign exchange risk associated with certain investments in these subsidiaries. The decrease in the carrying amount of $53 million noted in the “Payments, Foreign Currency Translation and Accretion” column in the table above primarily reflects the remeasurement of the 2029 Notes into U.S. dollars and is recorded in accumulated other comprehensive loss within Nasdaq's stockholders’ equity in the Condensed Consolidated Balance Sheets as of June 30, 2022. 2030 Notes In February 2020, Nasdaq issued the 2030 Notes, which pay interest annually at a rate of 0.875% in arrears, which began on February 13, 2021. The 2030 Notes were designated as a hedge of our net investment in certain foreign subsidiaries to mitigate the foreign exchange risk associated with certain investments in these subsidiaries. The decrease in the carrying amount of $53 million noted in the “Payments, Foreign Currency Translation and Accretion” column in the table above primarily reflects the remeasurement of the 2030 Notes into U.S. dollars and is recorded in accumulated other comprehensive loss within Nasdaq's stockholders’ equity in the Condensed Consolidated Balance Sheets as of June 30, 2022. 2050 Notes In April 2020, Nasdaq issued the 2050 Notes, which pay interest semi-annually at a rate of 3.25% per annum until April 28, 2050. Such rate may vary with Nasdaq's debt rating, to the extent Nasdaq is downgraded below investment grade, up to a rate not to exceed 5.25%. 2022, 2031 and 2040 Notes In December 2020, Nasdaq issued the 2022, 2031 and 2040 Notes. The net proceeds were used to partially fund the acquisition of Verafin. For further discussion of the acquisition of Verafin, see “2021 Acquisition,” of Note 4, “Acquisitions and Divestiture.” 2022 Notes The 2022 Notes pay interest semi-annually in arrears, which began on June 21, 2021. The interest rate of 0.445% may vary with Nasdaq's debt rating, to the extent Nasdaq is downgraded below investment grade, up to a rate not to exceed 2.445%. 2031 Notes The 2031 Notes pay interest semi-annually in arrears, which began on January 15, 2021. The interest rate of 1.650% may vary with Nasdaq's debt rating, to the extent Nasdaq is downgraded below investment grade, up to a rate not to exceed 3.65%. 2040 Notes The 2040 Notes pay interest semi-annually in arrears, which began on June 21, 2021. The interest rate of 2.500% may vary with Nasdaq's debt rating, to the extent Nasdaq is downgraded below investment grade, up to a rate not to exceed 4.50%. 2033 Notes In July 2021, Nasdaq issued the 2033 Notes, which pay interest annually in arrears, at a rate of 0.900%, beginning on July 30, 2022. The 2033 Notes have been designated as a hedge of our net investment in certain foreign subsidiaries to mitigate the foreign exchange risk associated with certain investments in these subsidiaries. The decrease in the carrying amount of $54 million noted in the “Payments, Foreign Currency Translation and Accretion” column in the table above primarily reflects the remeasurement of the 2033 Notes into U.S. dollars and is recorded in accumulated other comprehensive loss within Nasdaq stockholders’ equity in the Condensed Consolidated Balance Sheets as of June 30, 2022. 2052 Notes In March 2022, Nasdaq issued $550 million aggregate principal amount of 3.950% senior notes due in 2052, which pay interest semi-annually in arrears, beginning on September 7, 2022. The interest rate of 3.950% may vary with Nasdaq's debt rating, to the extent Nasdaq is downgraded below investment grade, up to a rate not to exceed 5.950%. The net proceeds from the 2052 Notes were approximately $541 million after deducting the underwriting discount and expenses of the offering. We used the net proceeds from the 2052 Notes to redeem all of the 2024 Notes in April 2022. Credit Facilities 2020 Credit Facility In December 2020, Nasdaq entered into the 2020 Credit Facility, which replaced a former credit facility and consists of a $1.25 billion five-year revolving credit facility (with sublimits for non-dollar borrowings, swingline borrowings and letters of credit). Nasdaq intends to use funds available under the 2020 Credit Facility for general corporate purposes and to provide liquidity support for the repayment of commercial paper issued through the commercial paper program. Nasdaq is permitted to repay borrowings under our 2020 Credit Facility at any time in whole or in part, without penalty. As of June 30, 2022, no amounts were outstanding on the 2020 Credit Facility. The $(3) million balance represents unamortized debt issuance costs which are being accreted through interest expense over the life of the credit facility. Borrowings under the revolving credit facility and swingline borrowings bear interest on the principal amount outstanding at a variable interest rate based on either the LIBOR (or a successor rate to LIBOR), the base rate (as defined in the credit agreement), or other applicable rate with respect to non-dollar borrowings, plus an applicable margin that varies with Nasdaq’s debt rating. We are charged commitment fees of 0.125% to 0.350%, depending on our credit rating, whether or not amounts have been borrowed. These commitment fees are included in interest expense and were not material for the three and six months ended June 30, 2022 and 2021. The 2020 Credit Facility contains financial and operating covenants. Financial covenants include a maximum leverage ratio. Operating covenants include, among other things, limitations on Nasdaq’s ability to incur additional indebtedness, grant liens on assets, dispose of assets and make certain restricted payments. The facility also contains customary affirmative covenants, including access to financial statements, notice of defaults and certain other material events, maintenance of properties and insurance, and customary events of default, including cross-defaults to our material indebtedness. The 2020 Credit Facility includes an option for Nasdaq to increase the available aggregate amount by up to $625 million, subject to the consent of the lenders funding the increase and certain other conditions. Other Credit Facilities Certain of our European subsidiaries have several other credit facilities, which are available in multiple currencies, primarily to support our Nasdaq Clearing operations in Europe, as well as to provide a cash pool credit line for one subsidiary. These credit facilities, in aggregate, totaled $188 million as of June 30, 2022 and $212 million as of December 31, 2021 in available liquidity, none of which was utilized. Generally, these facilities each have a one year term. The amounts borrowed under these various credit facilities bear interest on the principal amount outstanding at a variable interest rate based on a base rate (as defined in the applicable credit agreement), plus an applicable margin. We are charged commitment fees (as defined in the applicable credit agreement), whether or not amounts have been borrowed. These commitment fees are included in interest expense and were not material for the three and six months ended June 30, 2022 and 2021. These facilities include customary affirmative and negative operating covenants and events of default. Debt Covenants As of June 30, 2022, we were in compliance with the covenants of all of our debt obligations.

Retirement Benefits [Abstract]
Retirement Plans	RETIREMENT PLANS Defined Contribution Savings Plan We sponsor a 401(k) Plan for U.S. employees. Employees are immediately eligible to make contributions to the plan and are also eligible for an employer contribution match at an amount equal to 100.0% of the first 6.0% of eligible employee contributions. Savings plan expense included in compensation and benefits expense in the Condensed Consolidated Statements of Income was $4 million for the three months ended June 30, 2022, $3 million for the three months ended June 30, 2021, and $8 million for the six months ended June 30, 2022 and $7 million for the six months ended June 30, 2021. Pension and Supplemental Executive Retirement Plans We maintain non-contributory, defined-benefit pension plans, non-qualified SERPs for certain senior executives and other post-retirement benefit plans for eligible employees in the U.S. Our pension plans and SERPs are frozen. Future service and salary for all participants do not count toward an accrual of benefits under the pension plans and SERPs. Most employees outside the U.S. are covered by local retirement plans or by applicable social laws. Benefits under social laws are generally expensed in the periods in which the costs are incurred. The total expense for these plans is included in compensation and benefits expense in the Condensed Consolidated Statements of Income and was $6 million for the three months ended June 30, 2022, $7 million for the three months ended June 30, 2021, $12 million for the six months ended June 30, 2022 and $13 million for the six months ended June 30, 2021.

Share-Based Payment Arrangement [Abstract]
Share-Based Compensation	SHARE-BASED COMPENSATION We have a share-based compensation program for employees and non-employee directors. Share-based awards granted under this program include restricted stock (consisting of restricted stock units), PSUs and stock options. For accounting purposes, we consider PSUs to be a form of restricted stock. Summary of Share-Based Compensation Expense The following table presents the total share-based compensation expense resulting from equity awards and the 15.0% discount for the ESPP for the three and six months ended June 30, 2022 and 2021, which is included in compensation and benefits expense in the Condensed Consolidated Statements of Income: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 (in millions) Share-based compensation expense before income taxes $ 25 $ 24 $ 49 $ 43 Common Shares Available Under Our Equity Plan As of June 30, 2022, we had approximately 8.9 million shares of common stock authorized for future issuance under our Equity Plan. Restricted Stock We grant restricted stock to most employees. The grant date fair value of restricted stock awards is based on the closing stock price at the date of grant less the present value of future cash dividends. Restricted stock awards granted to employees below the manager level generally vest 33.3% on the first anniversary of the grant date, 33.3% on the second anniversary of the grant date, and 33.3% on the third anniversary of the grant date. Restricted stock awards granted to employees at or above the manager level generally vest 33.3% on the second anniversary of the grant date, 33.3% on the third anniversary of the grant date, and 33.3% on the fourth anniversary of the grant date. Summary of Restricted Stock Activity The following table summarizes our restricted stock activity for the six months ended June 30, 2022: Restricted Stock Number of Awards Weighted-Average Grant Date Fair Value Unvested at January 1, 2022 1,466,340 $ 106.16 Granted 465,704 175.98 Vested (464,316) 89.80 Forfeited (48,415) 119.80 Unvested at June 30, 2022 1,419,313 $ 133.96 As of June 30, 2022, $121 million of total unrecognized compensation cost related to restricted stock is expected to be recognized over a weighted-average period of 1.9 years. PSUs PSUs are based on performance measures that impact the amount of shares that each recipient will receive upon vesting. Prior to April 1, 2020, we had two performance-based PSU programs for certain officers, a one-year performance-based program and a three-year cumulative performance-based program that focuses on TSR. Effective April 1, 2020, to better align the equity programs for eligible officers, the one-year performance-based program was eliminated and all eligible officers now participate in the three-year cumulative performance-based program. While the performance periods are complete for all PSUs granted under the one-year performance-based program, some shares underlying these PSUs have not vested. One-Year PSU Program The grant date fair value of PSUs under the one-year performance-based program was based on the closing stock price at the date of grant less the present value of future cash dividends. Under this program, an eligible employee received a target grant of PSUs, but could have received from 0.0% to 150.0% of the target amount granted, depending on the achievement of performance measures. These awards vest ratably on an annual basis over a three-year period commencing with the end of the one-year performance period. Compensation cost is recognized over the performance period and the three-year vesting period based on the probability that such performance measures will be achieved, taking into account an estimated forfeiture rate. Three-Year PSU Program Under the three-year performance-based program, each eligible individual receives PSUs, subject to market conditions, with a three-year cumulative performance period that vest at the end of the performance period. Compensation cost is recognized over the three-year performance period, taking into account an estimated forfeiture rate, regardless of whether the market condition is satisfied, provided that the requisite service period has been completed. Performance will be determined by comparing Nasdaq’s TSR to two peer groups, each weighted 50.0%. The first peer group consists of exchange companies, and the second peer group consists of all companies in the S&P 500. Nasdaq’s relative performance ranking against each of these groups will determine the final number of shares delivered to each individual under the program. The award issuance under this program will be between 0.0% and 200.0% of the number of PSUs granted and will be determined by Nasdaq’s overall performance against both peer groups. However, if Nasdaq’s TSR is negative for the three-year performance period, regardless of TSR ranking, the award issuance will not exceed 100.0% of the number of PSUs granted. We estimate the fair value of PSUs granted under the three-year PSU program using the Monte Carlo simulation model, as these awards contain a market condition. Grants of PSUs that were issued in 2019 with a three-year performance period exceeded the applicable performance parameters. As a result, an additional 289,307 units above the original target were granted in the first quarter of 2022 and were fully vested upon issuance. The following weighted-average assumptions were used to determine the weighted-average fair values of the PSU awards granted under the three-year PSU program for the six months ended June 30, 2022 and 2021: June 30, 2022 June 30, 2021 Weighted-average risk free interest rate 2.55 % 0.31 % Expected volatility 30.33 % 30.11 % Weighted-average grant date share price $ 181.92 $ 150.85 Weighted-average fair value at grant date $ 190.51 $ 206.17 In the table above, the risk-free interest rate for periods within the expected life of the award is based on the U.S. Treasury yield curve in effect at the time of grant; and we use historic volatility for PSU awards issued under the three-year PSU program, as implied volatility data could not be obtained for all the companies in the peer groups used for relative performance measurement within the program. In addition, the annual dividend assumption utilized in the Monte Carlo simulation model is based on Nasdaq’s dividend yield at the date of grant. Summary of PSU Activity The following table summarizes our PSU activity for the six months ended June 30, 2022: PSUs One-Year Program Three-Year Program Number of Awards Weighted-Average Grant Date Fair Value Number of Awards Weighted-Average Grant Date Fair Value Unvested at January 1, 2022 49,734 $ 84.03 764,124 $ 135.04 Granted — — 490,364 135.88 Vested (2,075) 84.18 (578,614) 97.70 Forfeited (759) 84.18 (23,067) 149.66 Unvested at June 30, 2022 46,900 $ 84.02 652,807 $ 168.25 In the table above, the granted amount under the three year program reflects additional awards granted based on overachievement of performance parameters. As of June 30, 2022, $1 million of total unrecognized compensation cost related to the one-year PSU program is expected to be recognized over a weighted-average period of 1.0 year. For the three-year PSU program, $62 million of total unrecognized compensation cost is expected to be recognized over a weighted-average period of 1.5 years. Stock Options In January 2022, in connection with a new five year employment agreement, our President and Chief Executive Officer received an aggregate of 204,624 performance-based non-qualified stock options, which will vest as follows: • 50% will vest contingent upon the achievement of certain performance conditions; and • 50% will vest five years after the grant date, subject to continued employment through such date. The fair value of stock options are estimated using the Black-Scholes option-pricing model. These options expire 10 years after the date of grant. There were no stock option awards granted for the six months ended June 30, 2021. A summary of stock option activity for the six months ended June 30, 2022 is as follows: Number of Stock Options Weighted-Average Exercise Price Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in millions) Outstanding at December 31, 2021 268,817 $ 66.68 5.0 $ 39 Granted 204,624 202.46 Outstanding at June 30, 2022 473,441 $ 125.36 6.7 $ 23 Exercisable at June 30, 2022 268,817 $ 66.68 4.5 $ 23 The net cash proceeds from the exercise of 24,409 stock options for the six months ended June 30, 2021 was $1 million. As of June 30, 2022, the aggregate pre-tax intrinsic value of the outstanding and exercisable stock options in the above table was $23 million and represents the difference between our closing stock price on June 30, 2022 of $152.54 and the exercise price, times the number of shares that would have been received by the option holders had the option holders exercised their stock options on that date. This amount can change based on the fair market value of our common stock. As of June 30, 2021, 0.3 million outstanding stock options were exercisable and the weighted-average exercise price was $66.68. The total pre-tax intrinsic value of stock options exercised was $3 million for the six months ended June 30, 2021. ESPP We have an ESPP under which approximately 4.1 million shares of our common stock were available for future issuance as of June 30, 2022. Under our ESPP, employees may purchase shares having a value not exceeding 10.0% of their annual compensation, subject to applicable annual Internal Revenue Service limitations. We record compensation expense related to the 15.0% discount that is given to our employees, which totaled $3 million for both the three months ended June 30, 2022 and 2021 and $5 million for both the six months ended June 30, 2022 and 2021.

Equity [Abstract]
Nasdaq Stockholders' Equity	NASDAQ STOCKHOLDERS' EQUITY Common Stock As of June 30, 2022, 300,000,000 shares of our common stock were authorized, 170,888,738 shares were issued and 163,734,534 shares were outstanding. As of December 31, 2021, 300,000,000 shares of our common stock were authorized, 173,418,939 shares were issued and 166,679,635 shares were outstanding. The holders of common stock are entitled to one vote per share, except that our certificate of incorporation limits the ability of any shareholder to vote in excess of 5.0% of the then-outstanding shares of Nasdaq common stock. Common Stock in Treasury, at Cost We account for the purchase of treasury stock under the cost method with the shares of stock repurchased reflected as a reduction to Nasdaq stockholders’ equity and included in common stock in treasury, at cost in the Condensed Consolidated Balance Sheets. Shares repurchased under our share repurchase program are currently retired and canceled and are therefore not included in the common stock in treasury balance. If treasury shares are reissued, they are recorded at the average cost of the treasury shares acquired. We held 7,154,204 shares of common stock in treasury as of June 30, 2022 and 6,739,304 shares as of December 31, 2021, most of which are related to shares of our common stock withheld for the settlement of employee tax withholding obligations arising from the vesting of restricted stock and PSUs. Share Repurchase Program As discussed in “2021 Divestiture,” of Note 4, “Acquisitions and Divestiture,” in June 2021, our board of directors authorized an increase to our share repurchase program to an aggregate authorized amount of $1.5 billion. As of June 30, 2022, the remaining aggregate authorized amount under the existing share repurchase program was $293 million. These repurchases may be made from time to time at prevailing market prices in open market purchases, privately-negotiated transactions, block purchase techniques, an accelerated share repurchase program or otherwise, as determined by our management. The repurchases are primarily funded from existing cash balances. The share repurchase program may be suspended, modified or discontinued at any time, and has no defined expiration date. The following is a summary of our share repurchase activity, excluding the repurchases done through our ASR agreement described below, reported based on settlement date, for the six months ended June 30, 2022: Six Months Ended June 30, 2022 Number of shares of common stock repurchased 1,821,865 Average price paid per share $ 168.78 Total purchase price (in millions) $ 308 In the table above, the number of shares of common stock repurchased excludes an aggregate of 414,900 shares withheld upon the vesting of restricted stock and PSUs for the six months ended June 30, 2022. As discussed above in “Common Stock in Treasury, at Cost,” shares repurchased under our share repurchase program are currently retired and cancelled. ASR Agreement In January 2022, we entered into an ASR agreement to repurchase $325 million of common stock. We received a total delivery of 1,876,387 shares of common stock and completed the ASR program during the first quarter of 2022. Preferred Stock Our certificate of incorporation authorizes the issuance of 30,000,000 shares of preferred stock, par value $0.01 per share, issuable from time to time in one or more series. As of June 30, 2022 and December 31, 2021, no shares of preferred stock were issued or outstanding. Stock Split In April 2022, we announced our plan to seek shareholder and SEC approval for an increase in the number of authorized shares of common stock in order to effect a 3-for-1 stock split of the Company’s common stock in the form of a stock dividend. In June 2022, we received the necessary approvals. In July 2022, our board of directors approved and declared the stock split in the form of a stock dividend. The record date for the stock dividend is August 12, 2022, with a distribution date of August 26, 2022 and we expect trading to begin on a split-adjusted basis on August 29, 2022. Cash Dividends on Common Stock During the first six months of 2022, our board of directors declared and paid the following cash dividends: Declaration Date Dividend Per Record Date Total Amount Paid Payment Date (in millions) January 26, 2022 $ 0.54 March 11, 2022 $ 88 March 25, 2022 April 20, 2022 0.60 June 10, 2022 98 June 24, 2022 $ 186 The total amount paid of $186 million was recorded in retained earnings within Nasdaq's stockholders' equity in the Condensed Consolidated Balance Sheets at June 30, 2022. In July 2022, the board of directors approved a regular quarterly cash dividend of $0.20 per share on our outstanding common stock. On a split-adjusted basis, the dividend is economically equivalent to the pre-split quarterly dividend of $0.60 per share on our outstanding common stock paid in the preceding quarter. The dividend is payable on September 30, 2022 to shareholders of record at the close of business on September 16, 2022. The estimated amount of this dividend is $98 million. Future declarations of quarterly dividends and the establishment of future record and payment dates are subject to approval by the board of directors. The board of directors maintains a dividend policy with the intention to provide stockholders with regular and increasing dividends as earnings and cash flows increase.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS The following tables present our financial assets and financial liabilities that were measured at fair value on a recurring basis as of June 30, 2022 and December 31, 2021. June 30, 2022 Total Level 1 Level 2 Level 3 (in millions) European government debt securities $ 132 $ 132 $ — $ — Swedish mortgage bonds 20 — 20 — Commercial paper 9 — 9 — Total assets at fair value $ 161 $ 132 $ 29 $ — December 31, 2021 Total Level 1 Level 2 Level 3 (in millions) European government debt securities $ 144 $ 144 $ — $ — Corporate debt securities 20 — 20 — State-owned enterprises and municipal securities 11 — 11 — Swedish mortgage bonds 21 — 21 — Time deposits 12 — 12 — Total assets at fair value $ 208 $ 144 $ 64 $ — Financial Instruments Not Measured at Fair Value on a Recurring Basis Some of our financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. Such financial assets and financial liabilities include: cash and cash equivalents, restricted cash and cash equivalents, receivables, net, certain other current assets, accounts payable and accrued expenses, Section 31 fees payable to SEC, accrued personnel costs, commercial paper and certain other current liabilities. Our investment in OCC is accounted for under the equity method of accounting. We have elected the measurement alternative for the majority of our equity securities, which primarily represent various strategic investments made through our corporate venture program. See “Equity Method Investments,” and “Equity Securities,” of Note 6, “Investments,” for further discussion. We also consider our debt obligations to be financial instruments. As of June 30, 2022, the majority of our debt obligations were fixed-rate obligations. We are exposed to changes in interest rates as a result of borrowings under our 2020 Credit Facility, as the interest rates on this facility have a variable rate depending on the maturity of the borrowing and the implied underlying reference rate. As of June 30, 2022, we had no outstanding borrowings under our 2020 Credit Facility. We are also exposed to changes in interest rates as a result of the amounts outstanding from the sale of commercial paper under our commercial paper program. As of June 30, 2022, we had $421 million outstanding under our commercial paper program. The fair value of our debt obligations utilizing discounted cash flow analyses for our floating rate debt, and prevailing market rates for our fixed rate debt was $4.8 billion as of June 30, 2022 and $5.9 billion as of December 31, 2021. The discounted cash flow analyses are based on borrowing rates currently available to us for debt with similar terms and maturities. The fair value of our commercial paper as of June 30, 2022 approximated the carrying value since the rates of interest on this short-term debt approximated market rates. Our commercial paper and our fixed rate and floating rate debt are categorized as Level 2 in the fair value hierarchy. For further discussion of our debt obligations, see Note 8, “Debt Obligations.” Non-Financial Assets Measured at Fair Value on a Non-Recurring Basis Our non-financial assets, which include goodwill, intangible assets, and other long-lived assets, are not required to be carried at fair value on a recurring basis. Fair value measures of non-financial assets are primarily used in the impairment analysis of these assets. Any resulting asset impairment would require that the non-financial asset be recorded at its fair value. Nasdaq uses Level 3 inputs to measure the fair value of the above assets on a non-recurring basis. As of June 30, 2022 and December 31, 2021, there were no non-financial assets measured at fair value on a non-recurring basis.

Clearing Operations

Clearing Operations	6 Months Ended
	Jun. 30, 2022
Due to and from Broker-Dealers and Clearing Organizations [Abstract]
Clearing Operations	CLEARING OPERATIONS Nasdaq Clearing Nasdaq Clearing is authorized and supervised under EMIR as a multi-asset clearinghouse by the SFSA. Such authorization is effective for all member states of the European Union and certain other non-member states that are part of the European Economic Area, including Norway. The clearinghouse acts as the CCP for exchange and OTC trades in equity derivatives, fixed income derivatives, resale and repurchase contracts, power derivatives, emission allowance derivatives, and seafood derivatives. Through our clearing operations in the financial markets, which include the resale and repurchase market, the commodities markets, and the seafood market, Nasdaq Clearing is the legal counterparty for, and guarantees the fulfillment of, each contract cleared. These contracts are not used by Nasdaq Clearing for the purpose of trading on its own behalf. As the legal counterparty of each transaction, Nasdaq Clearing bears the counterparty risk between the purchaser and seller in the contract. In its guarantor role, Nasdaq Clearing has precisely equal and offsetting claims to and from clearing members on opposite sides of each contract, standing as the CCP on every contract cleared. In accordance with the rules and regulations of Nasdaq Clearing, default fund and margin collateral requirements are calculated for each clearing member’s positions in accounts with the CCP. See “Default Fund Contributions and Margin Deposits” below for further discussion of Nasdaq Clearing’s default fund and margin requirements. Nasdaq Clearing maintains three member sponsored default funds: one related to financial markets, one related to commodities markets and one related to the seafood market. Under this structure, Nasdaq Clearing and its clearing members must contribute to the total regulatory capital related to the clearing operations of Nasdaq Clearing. This structure applies an initial separation of default fund contributions for the financial, commodities and seafood markets in order to create a buffer for each market’s counterparty risks. See “Default Fund Contributions” below for further discussion of Nasdaq Clearing’s default fund. A power of assessment and a liability waterfall have also been implemented to further align risk between Nasdaq Clearing and its clearing members. See “Power of Assessment” and “Liability Waterfall” below for further discussion. Nasdaq Commodities Clearing Default In September 2018, a member of the Nasdaq Clearing commodities market defaulted due to the inability to post sufficient collateral to cover increased margin requirements for the positions of the relevant member, which had experienced losses due to sharp adverse movements in the Nordic - German power market spread. Nasdaq Clearing followed default procedures and offset the future market risk on the defaulting member’s positions. Immediately following the event, Nasdaq Clearing launched a comprehensive enhancement program to strengthen the resilience and robustness of the clearinghouse. In December 2018, the SFSA initiated a review of Nasdaq Clearing. In January 2021, the SFSA issued a warning combined with an administrative fine of approximately $29 million (SEK 300 million) to Nasdaq Clearing based on its review. Nasdaq Clearing appealed the SFSA´s decision to the Administrative Court. In December 2021, the court rejected Nasdaq Clearing’s appeal and upheld the decision of the SFSA. In January 2022, Nasdaq Clearing appealed this decision to the Administrative Court of Appeal, with the next hearing date set for October 2022. While we continue to firmly believe in the merit of our appeal, due to the recent decision by the Administrative Court, we have determined it is appropriate to record an accrual for the full amount of the administrative fine issued by the SFSA. The charge was included in regulatory expense in our Consolidated Statements of Income for the year ended December 31, 2021. Default Fund Contributions and Margin Deposits As of June 30, 2022, clearing member default fund contributions and margin deposits were as follows: June 30, 2022 Cash Contributions Non-Cash Contributions Total Contributions (in millions) Default fund contributions $ 763 $ 115 $ 878 Margin deposits 7,925 8,063 15,988 Total $ 8,688 $ 8,178 $ 16,866 Of the total default fund contributions of $878 million, Nasdaq Clearing can utilize $782 million as capital resources in the event of a counterparty default. The remaining balance of $96 million pertains to member posted surplus balances. Our clearinghouse holds material amounts of clearing member cash deposits which are held or invested primarily to provide security of capital while minimizing credit, market and liquidity risks. While we seek to achieve a reasonable rate of return, we are primarily concerned with preservation of capital and managing the risks associated with these deposits. Clearing member cash contributions are maintained in demand deposits held at central banks and large, highly rated financial institutions or secured through direct investments, primarily central bank certificates and highly rated European government debt securities with original maturities primarily 1 year or less, reverse repurchase agreements and multilateral development bank debt securities. Investments in reverse repurchase agreements range in maturity from 1 day to 15 days and are secured with highly rated government securities and multilateral development banks. The carrying value of these securities approximates their fair value due to the short-term nature of the instruments and reverse repurchase agreements. Nasdaq Clearing has invested the total cash contributions of $8,688 million as of June 30, 2022 and $5,911 million as of December 31, 2021, in accordance with its investment policy as follows: June 30, 2022 December 31, 2021 (in millions) Demand deposits $ 6,869 $ 3,061 Central bank certificates 900 2,013 Restricted cash and cash equivalents $ 7,769 $ 5,074 European government debt securities 447 414 Reverse repurchase agreements 282 152 Multilateral development bank debt securities 190 271 Investments $ 919 $ 837 Total $ 8,688 $ 5,911 In the preceding table, the change from December 31, 2021 to June 30, 2022 includes currency translation adjustments of $657 million for restricted cash and cash equivalents and $120 million for investments. For the six months ended June 30, 2022 and 2021 investments related to default funds and margin deposits, net includes purchases of investment securities of $17,539 million and $20,419 million, respectively, and proceeds from sales and redemptions of investment securities of $17,337 million and $20,329 million, respectively. In the investment activity related to default fund and margin contributions, we are exposed to counterparty risk related to reverse repurchase agreement transactions, which reflect the risk that the counterparty might become insolvent and, thus, fail to meet its obligations to Nasdaq Clearing. We mitigate this risk by only engaging in transactions with high credit quality reverse repurchase agreement counterparties and by limiting the acceptable collateral under the reverse repurchase agreement to high quality issuers, primarily government securities and other securities explicitly guaranteed by a government. The value of the underlying security is monitored during the lifetime of the contract, and in the event the market value of the underlying security falls below the reverse repurchase amount, our clearinghouse may require additional collateral or a reset of the contract. Default Fund Contributions Required contributions to the default funds are proportional to the exposures of each clearing member. When a clearing member is active in more than one market, contributions must be made to all markets’ default funds in which the member is active. Clearing members’ eligible contributions may include cash and non-cash contributions. Cash contributions received are maintained in demand deposits held at central banks and large, highly rated financial institutions or invested by Nasdaq Clearing, in accordance with its investment policy, either in central bank certificates, highly rated government debt securities, reverse repurchase agreements with highly rated government debt securities as collateral, or multilateral development bank debt securities. Nasdaq Clearing maintains and manages all cash deposits related to margin collateral. All risks and rewards of collateral ownership, including interest, belong to Nasdaq Clearing. Clearing members’ cash contributions are included in default funds and margin deposits in the Condensed Consolidated Balance Sheets as both a current asset and a current liability. Non-cash contributions include highly rated government debt securities that must meet specific criteria approved by Nasdaq Clearing. Non-cash contributions are pledged assets that are not recorded in the Condensed Consolidated Balance Sheets as Nasdaq Clearing does not take legal ownership of these assets and the risks and rewards remain with the clearing members. These balances may fluctuate over time due to changes in the amount of deposits required and whether members choose to provide cash or non-cash contributions. Assets pledged are held at a nominee account in Nasdaq Clearing’s name for the benefit of the clearing members and are immediately accessible by Nasdaq Clearing in the event of a default. In addition to clearing members’ required contributions to the liability waterfall, Nasdaq Clearing is also required to contribute capital to the liability waterfall and overall regulatory capital as specified under its clearinghouse rules. As of June 30, 2022, Nasdaq Clearing committed capital totaling $123 million to the liability waterfall and overall regulatory capital, in the form of government debt securities, which are recorded as financial investments in the Condensed Consolidated Balance Sheets. The combined regulatory capital of the clearing members and Nasdaq Clearing is intended to secure the obligations of a clearing member exceeding such member’s own margin and default fund deposits and may be used to cover losses sustained by a clearing member in the event of a default. Margin Deposits Nasdaq Clearing requires all clearing members to provide collateral, which may consist of cash and non-cash contributions, to guarantee performance on the clearing members’ open positions, or initial margin. In addition, clearing members must also provide collateral to cover the daily margin call if needed. See “Default Fund Contributions” above for further discussion of cash and non-cash contributions. Similar to default fund contributions, Nasdaq Clearing maintains and manages all cash deposits related to margin collateral. All risks and rewards of collateral ownership, including interest, belong to Nasdaq Clearing and are recorded in revenues. These cash deposits are recorded in default funds and margin deposits in the Condensed Consolidated Balance Sheets as both a current asset and a current liability. Pledged margin collateral is not recorded in our Condensed Consolidated Balance Sheets as all risks and rewards of collateral ownership, including interest, belong to the counterparty. Assets pledged are held at a nominee account in Nasdaq Clearing’s name for the benefit of the clearing members and are immediately accessible by Nasdaq Clearing in the event of a default. Nasdaq Clearing marks to market all outstanding contracts and requires payment from clearing members whose positions have lost value. The mark-to-market process helps identify any clearing members that may not be able to satisfy their financial obligations in a timely manner allowing Nasdaq Clearing the ability to mitigate the risk of a clearing member defaulting due to exceptionally large losses. In the event of a default, Nasdaq Clearing can access the defaulting member’s margin and default fund deposits to cover the defaulting member’s losses. Regulatory Capital and Risk Management Calculations Nasdaq Clearing manages risk through a comprehensive counterparty risk management framework, which is comprised of policies, procedures, standards and financial resources. The level of regulatory capital is determined in accordance with Nasdaq Clearing’s regulatory capital and default fund policy, as approved by the SFSA. Regulatory capital calculations are continuously updated through a proprietary capital-at-risk calculation model that establishes the appropriate level of capital. As mentioned above, Nasdaq Clearing is the legal counterparty for each contract cleared and thereby guarantees the fulfillment of each contract. Nasdaq Clearing accounts for this guarantee as a performance guarantee. We determine the fair value of the performance guarantee by considering daily settlement of contracts and other margining and default fund requirements, the risk management program, historical evidence of default payments, and the estimated probability of potential default payouts. The calculation is determined using proprietary risk management software that simulates gains and losses based on historical market prices, extreme but plausible market scenarios, volatility and other factors present at that point in time for those particular unsettled contracts. Based on this analysis, excluding any liability related to the Nasdaq commodities clearing default (see discussion above), the estimated liability was nominal and no liability was recorded as of June 30, 2022. Power of Assessment To further strengthen the contingent financial resources of the clearinghouse, Nasdaq Clearing has power of assessment that provides the ability to collect additional funds from its clearing members to cover a defaulting member’s remaining obligations up to the limits established under the terms of the clearinghouse rules. The power of assessment corresponds to 230.0% of the clearing member’s aggregate contribution to the financial, commodities and seafood markets’ default funds. Liability Waterfall The liability waterfall is the priority order in which the capital resources would be utilized in the event of a default where the defaulting clearing member’s collateral and default fund contribution would not be sufficient to cover the cost to settle its portfolio. If a default occurs and the defaulting clearing member’s collateral, including cash deposits and pledged assets, is depleted, then capital is utilized in the following amount and order: • junior capital contributed by Nasdaq Clearing, which totaled $40 million as of June 30, 2022; • a loss-sharing pool related only to the financial market that is contributed to by clearing members and only applies if the defaulting member’s portfolio includes interest rate swap products; • specific market default fund where the loss occurred (i.e., the financial, commodities, or seafood market), which includes capital contributions of the clearing members on a pro-rata basis; and • fully segregated senior capital for each specific market contributed by Nasdaq Clearing, calculated in accordance with clearinghouse rules, which totaled $21 million as of June 30, 2022. If additional funds are needed after utilization of the liability waterfall, or if part of the waterfall has been utilized and needs to be replenished, then Nasdaq Clearing will utilize its power of assessment and additional capital contributions will be required by non-defaulting members up to the limits established under the terms of the clearinghouse rules. In addition to the capital held to withstand counterparty defaults described above, Nasdaq Clearing also has committed capital of $62 million to ensure that it can handle an orderly wind-down of its operation, and that it is adequately protected against investment, operational, legal, and business risks. Market Value of Derivative Contracts Outstanding The following table presents the market value of derivative contracts outstanding prior to netting: June 30, 2022 (in millions) Commodity and seafood options, futures and forwards $ 1,097 Fixed-income options and futures 1,969 Stock options and futures 226 Index options and futures 74 Total $ 3,366 In the table above: • We determined the fair value of our option contracts using standard valuation models that were based on market-based observable inputs including implied volatility, interest rates and the spot price of the underlying instrument. • We determined the fair value of our futures contracts based upon quoted market prices and average quoted market yields. • We determined the fair value of our forward contracts using standard valuation models that were based on market-based observable inputs including benchmark rates and the spot price of the underlying instrument. Derivative Contracts Cleared The following table presents the total number of derivative contracts cleared through Nasdaq Clearing for the six months ended June 30, 2022 and 2021: Six Months Ended June 30, 2022 2021 Commodity and seafood options, futures and forwards 182,341 312,002 Fixed-income options and futures 12,287,280 12,185,338 Stock options and futures 8,980,694 10,607,666 Index options and futures 23,463,638 17,970,912 Total 44,913,953 41,075,918 In the table above, the total volume in cleared power related to commodity contracts was 250 Terawatt hours (TWh) and 456 TWh for the six months ended June 30, 2022 and 2021, respectively. Resale and Repurchase Agreements Contracts Outstanding and Cleared The outstanding contract value of resale and repurchase agreements was $3.0 billion as of June 30, 2022 and the total number of resale and repurchase agreements contracts cleared was 3,117,583 for the six months ended June 30, 2022.

Income Taxes	INCOME TAXES Income Tax Provision The following table presents our income tax provision and effective tax rate: Three Months Ended June 30, 2022 June 30, 2021 (in millions) Income tax provision $ 90 $ 113 Effective tax rate 22.7 % 24.9 % Six Months Ended June 30, 2022 June 30, 2021 (in millions) Income tax provision $ 182 $ 210 Effective tax rate 23.6 % 24.7 % The lower effective tax rate for both the three and six months ended June 30, 2022 was primarily due to the income tax effect on geographic mix of earnings and higher tax benefit from vested share-based awards in the U.S. The effective tax rate may vary from period to period depending on, among other factors, the geographic and business mix of earnings and losses. These same and other factors, including history of pre-tax earnings and losses, are taken into account in assessing the ability to realize deferred tax assets. Tax Audits Nasdaq and its eligible subsidiaries file a consolidated U.S. federal income tax return, applicable state and local income tax returns and non-U.S. income tax returns. We are subject to examination by federal, state and local, and foreign tax authorities. Our Federal income tax returns for the years 2018 through 2020 are subject to examination by the Internal Revenue Service. Several state tax returns are currently under examination by the respective tax authorities for the years 2012 through 2018, while 2019 and 2020 are subject to examination. Non-U.S. tax returns are subject to examination by the respective tax authorities for the years 2015 through 2020. We regularly assess the likelihood of additional assessments by each jurisdiction and have established tax reserves that we believe are adequate in relation to the potential for additional assessments. Examination outcomes and the timing of examination settlements are subject to uncertainty. Although the results of such examinations may have an impact on our unrecognized tax benefits, we do not anticipate that such impact will be material to our condensed consolidated financial position or results of operations, but may be material to our operating results for a particular period and the effective tax rate for that period. We do not expect the settlement of any tax audits to be material in the next twelve months.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Guarantees	COMMITMENTS, CONTINGENCIES AND GUARANTEES Guarantees Issued and Credit Facilities Available In addition to the default fund contributions and margin collateral pledged by clearing members discussed in Note 14, “Clearing Operations,” we have obtained financial guarantees and credit facilities, which are guaranteed by us through counter indemnities, to provide further liquidity related to our clearing businesses. Financial guarantees issued to us totaled $4 million as of June 30, 2022 and $5 million December 31, 2021. As discussed in “Other Credit Facilities,” of Note 8, “Debt Obligations,” we also have credit facilities primarily related to our Nasdaq Clearing operations, which are available in multiple currencies, and totaled $188 million as of June 30, 2022 and $212 million as of December 31, 2021 in available liquidity, none of which was utilized. Other Guarantees Through our clearing operations in the financial markets, Nasdaq Clearing is the legal counterparty for, and guarantees the performance of, its clearing members. See Note 14, “Clearing Operations,” for further discussion of Nasdaq Clearing performance guarantees. We have provided a guarantee related to lease obligations for The Nasdaq Entrepreneurial Center, Inc., which is a not-for-profit organization designed to convene, connect and engage aspiring and current entrepreneurs. This entity is not included in the condensed consolidated financial statements of Nasdaq. We believe that the potential for us to be required to make payments under these arrangements is unlikely. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for the above guarantees. Routing Brokerage Activities One of our broker-dealer subsidiaries, Nasdaq Execution Services, provides a guarantee to securities clearinghouses and exchanges under its standard membership agreements, which require members to guarantee the performance of other members. If a member becomes unable to satisfy its obligations to a clearinghouse or exchange, other members would be required to meet its shortfalls. To mitigate these performance risks, the exchanges and clearinghouses often require members to post collateral, as well as meet certain minimum financial standards. Nasdaq Execution Services’ maximum potential liability under these arrangements cannot be quantified. However, we believe that the potential for Nasdaq Execution Services to be required to make payments under these arrangements is unlikely. Accordingly, no contingent liability is recorded in the Condensed Consolidated Balance Sheets for these arrangements. Legal and Regulatory Matters Armenian Stock Exchange Investigation As disclosed in our prior filings with the SEC, a former non-U.S. subsidiary of Nasdaq, NASDAQ OMX Armenia OJSC, operated the Armenian Stock Exchange and the Central Depository of Armenia, which are regulated by the Central Bank of Armenia under Armenian law. In accordance with the requirements of Armenian law, Mellat Bank SB CJSC, an Armenian entity that is designated under Executive Order 13382, was a market participant on the Armenian Stock Exchange and, as a result, paid participation and transaction fees to the Armenian Stock Exchange during the period from 2012-2014. In 2014, we voluntarily self-disclosed this matter to the U.S. Department of Treasury’s Office of Foreign Assets Control, or OFAC, and received authorization from OFAC to continue, if necessary, certain activities pertaining to Mellat Bank SB CJSC in Armenia in a limited manner. In 2015, Nasdaq sold a majority of its ownership of Nasdaq OMX Armenia OJSC, with the remaining minority interest sold in 2018. OFAC has been conducting an inquiry into the Armenian Stock Exchange matter described above and in our prior filings since 2016, and during the first quarter of 2021, we were advised that OFAC is considering a civil monetary penalty in connection with that matter. We are currently in discussions with OFAC. While we believe our decision to voluntarily self-report this issue and our continued cooperation with OFAC, along with the permit we received from OFAC in connection with our transactions involving the Armenian Stock Exchange, will be mitigating factors with respect to the matter, any monetary fines or restrictions may nonetheless be material to our financial results in the period in which they are imposed. We cannot currently predict when our discussions with OFAC will conclude or the amount of any potential penalties imposed. Accordingly, we are unable to reasonably estimate any potential loss or range of loss and we have not accrued for a loss contingency. CFTC Matter In June 2022, NASDAQ Futures, Inc. (“NFX”), a non-operational, wholly-owned subsidiary of Nasdaq, received a telephonic “Wells Notice” from the staff of the CFTC relating to certain alleged potential violations by NFX of provisions of the Commodity Exchange Act and CFTC rules thereunder during the period beginning July 2015 through October 2018. The Wells Notice informed NFX that the CFTC staff has made, subject to consideration of NFX’s response, a preliminary determination to recommend that the CFTC authorize an enforcement action against NFX in connection with its former futures exchange business. Nasdaq sold NFX’s futures exchange business to a third-party in November 2019, including the portfolio of open interest in NFX contracts. During 2020, all remaining open interest in NFX contracts was migrated to other exchanges and NFX ceased operation. NFX plans to contest the staff’s positions in its response to the Wells Notice. A Wells Notice is neither a formal charge of wrongdoing nor a final determination that the recipient has violated any law. Accordingly, we are unable to reasonably estimate any potential loss or range of loss, and therefore, we have not accrued for a loss contingency. Nasdaq Commodities Clearing Default In December 2021, we recorded a charge related to an administrative fine issued by the SFSA associated with the default which occurred in 2018. The charge was included in regulatory expense in our Consolidated Statements of Income for the year ended December 31, 2021. See “Nasdaq Commodities Clearing Default,” of Note 14, “Clearing Operations,” for further information. Other Matters Except as disclosed above and in prior reports filed under the Exchange Act, we are not currently a party to any litigation or proceeding that we believe could have a material adverse effect on our business, consolidated financial condition, or operating results. However, from time to time, we have been threatened with, or named as a defendant in, lawsuits or involved in regulatory proceedings. In the normal course of business, Nasdaq discusses matters with its regulators raised during regulatory examinations or otherwise subject to their inquiries. Management believes that censures, fines, penalties or other sanctions that could result from any ongoing examinations or inquiries will not have a material impact on its consolidated financial position or results of operations. However, we are unable to predict the outcome or the timing of the ultimate resolution of these matters, or the potential fines, penalties or injunctive or other equitable relief, if any, that may result from these matters. Tax Audits We are engaged in ongoing discussions and audits with taxing authorities on various tax matters, the resolutions of which are uncertain. Currently, there are matters that may lead to assessments, some of which may not be resolved for several years. Based on currently available information, we believe we have adequately provided for any assessments that could result from those proceedings where it is more likely than not that we will be assessed. We review our positions on these matters as they progress. See “Tax Audits,” of Note 16, “Income Taxes,” for further discussion.

Business Segments	BUSINESS SEGMENTS We manage, operate and provide our products and services in four business segments: Market Technology, Investment Intelligence, Corporate Platforms and Market Services. See Note 1, “Organization and Nature of Operations,” for further discussion of our reportable segments. Our management allocates resources, assesses performance and manages these businesses as four separate segments. We evaluate the performance of our segments based on several factors, of which the primary financial measure is operating income. Results of individual businesses are presented based on our management accounting practices and structure. Our chief operating decision maker does not review total assets or statements of income below operating income by segments as key performance metrics; therefore, such information is not presented below. The following table presents certain information regarding our business segments for the three months ended June 30, 2022 and 2021: Three Months Ended June 30, 2022 2021 Market Technology (in millions) Total revenues $ 131 $ 117 Operating income 16 17 Investment Intelligence Total revenues 283 261 Operating income 186 169 Corporate Platforms Total revenues 168 149 Operating income 78 62 Market Services Total revenues 969 874 Transaction-based expenses (659) (566) Revenues less transaction-based expenses 310 308 Operating income 200 200 Corporate Items Total revenues 1 11 Operating loss (68) (72) Consolidated Total revenues $ 1,552 $ 1,412 Transaction-based expenses (659) (566) Revenues less transaction-based expenses $ 893 $ 846 Operating income $ 412 $ 376 The following table presents certain information regarding our business segments for the six months ended June 30, 2022 and 2021: Six Months Ended June 30, 2022 2021 Market Technology (in millions) Total revenues $ 255 $ 217 Operating income 20 15 Investment Intelligence Total revenues 567 516 Operating income 369 333 Corporate Platforms Total revenues 336 296 Operating income 152 122 Market Services Total revenues 1,927 2,010 Transaction-based expenses (1,302) (1,366) Revenues less transaction-based expenses 625 644 Operating income 401 428 Corporate Items Total revenues 2 24 Operating loss (125) (157) Consolidated Total revenues $ 3,087 $ 3,063 Transaction-based expenses (1,302) (1,366) Revenues less transaction-based expenses $ 1,785 $ 1,697 Operating income $ 817 $ 741 Certain amounts are allocated to corporate items in our management reports as we believe they do not contribute to a meaningful evaluation of a particular segment's ongoing operating performance. These items, which are presented in the table below, include the following: • Amortization expense of acquired intangible assets: We amortize intangible assets acquired in connection with various acquisitions. Intangible asset amortization expense can vary from period to period due to episodic acquisitions completed, rather than from our ongoing business operations. As such, if intangible asset amortization is included in performance measures, it is more difficult to assess the day-to-day operating performance of the segments, and the relative operating performance of the segments between periods. Management does not consider intangible asset amortization expense for the purpose of evaluating the performance of our segments or their managers or when making decisions to allocate resources. Therefore, we believe performance measures excluding intangible asset amortization expense provide management with a useful representation of our segments' ongoing activity in each period. • Merger and strategic initiatives expense: We have pursued various strategic initiatives and completed acquisitions and divestitures in recent years that have resulted in expenses which would not have otherwise been incurred. These expenses generally include integration costs, as well as legal, due diligence and other third-party transaction costs. The frequency and the amount of such expenses vary significantly based on the size, timing and complexity of the transaction. Management does not consider merger and strategic initiatives expense for the purpose of evaluating the performance of our segments or their managers or when making decisions to allocate resources. Therefore, we believe performance measures excluding merger and strategic initiatives expense provide management with a useful representation of our segments' ongoing activity in each period. • Restructuring charges: We initiated the transition of certain technology platforms to advance our strategic opportunities as a technology and analytics provider and continue the realignment of certain business areas. See Note 19, “Restructuring Charges,” for further discussion of our 2019 restructuring plan. We believe performance measures excluding restructuring charges provide management with a useful representation of our segments' ongoing activity in each period. • Revenues and expenses - divested/contributed businesses: We have included in corporate items the revenues and expenses of our U.S. Fixed Income business, which was previously included in our Market Services and Investment Intelligence results. See “2021 Divestiture,” of Note 4, “Acquisitions and Divestiture,” for further discussion of this divestiture. Additionally, other revenues related to a transitional services agreement associated with a divested business are included in corporate items. Also included are the revenues and expenses associated with the NPM business, which we contributed in July 2021 to a standalone, independent company, of which we own the largest minority interest together with a consortium of third-party financial institutions. Prior to July 2021, these revenues were previously included in our Corporate Platforms results. • Other items: We have included certain other charges or gains in corporate items, to the extent we believe they should be excluded when evaluating the ongoing operating performance of each individual segment. For the three and six months ended June 30, 2022, other items primarily include a loss on extinguishment of debt. The above charges are recorded in general, administrative and other expense, unless otherwise noted, in our Condensed Consolidated Statements of Income. The following table summarizes our Corporate Items: Three Months Ended June 30, 2022 2021 (in millions) Revenues - divested/contributed businesses $ 1 $ 11 Expenses: Amortization expense of acquired intangible assets $ 39 $ 40 Merger and strategic initiatives expense 12 12 Restructuring charges — 21 Extinguishment of debt 16 — Expenses - divested/contributed businesses — 5 Other 2 5 Total expenses 69 83 Operating loss $ (68) $ (72) Six Months Ended June 30, 2022 2021 (in millions) Revenues - divested/contributed businesses $ 2 $ 24 Expenses: Amortization expense of acquired intangible assets 78 76 Merger and strategic initiatives expense 27 57 Restructuring charges — 31 Extinguishment of debt 16 — Expenses - divested/contributed businesses — 10 Other 6 7 Total expenses 127 181 Operating loss $ (125) $ (157) For further discussion of our segments’ results, see “Segment Operating Results,” of “Item 2.

Restructuring and Related Activities [Abstract]
Restructuring Charges	RESTRUCTURING CHARGESIn September 2019, we initiated the transition of certain technology platforms to advance the Company's strategic opportunities as a technology and analytics provider and continue the realignment of certain business areas. In connection with these restructuring efforts, we retired certain elements of our marketplace infrastructure and technology product offerings as we implement NFF and other technologies internally and externally. This represented a fundamental shift in our strategy and technology as well as executive realignment. In June 2021, we completed our 2019 restructuring plan and recognized total pre-tax charges of $118 million over a two-year period. Total pre-tax charges related primarily to non-cash items such as asset impairments and accelerated depreciation, and third-party consulting costs. Severance and employee-related charges were also incurred. The following table presents a summary of the 2019 restructuring plan charges in the Condensed Consolidated Statements of Income for the three and six months ended June 30, 2021 which primarily consisted of consulting services, asset impairment charges primarily related to capitalized software that was retired, and accelerated depreciation expense on certain assets as a result of a decrease in their useful life.

Accounting Policies [Abstract]
Basis of Presentation	The condensed consolidated financial statements are prepared in accordance with U.S. GAAP and include the accounts of Nasdaq, its wholly-owned subsidiaries and other entities in which Nasdaq has a controlling financial interest. When we do not have a controlling interest in an entity, but exercise significant influence over the entity’s operating and financial policies, such investment is accounted for under the equity method of accounting. We recognize our share of earnings or losses of an equity method investee based on our ownership percentage. See “Equity Method Investments,” of Note 6, “Investments,” for further discussion of our equity method investments.
Principles of Consolidation	The accompanying condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results. These adjustments are of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation. As permitted under U.S. GAAP, certain footnotes or other financial information can be condensed or omitted in the interim condensed consolidated financial statements. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in Nasdaq’s Form 10-K. The year-end condensed balance sheet data was derived from the audited financial statements, but does not include all disclosures required by U.S. GAAP.
Reclassification	Certain prior year amounts have been reclassified to conform to the current year presentation. During the fourth quarter of 2021, we began adjusting the presentation of cash and cash equivalents held within default funds and margin deposits on the condensed consolidated statement of cash flows from operating activities, to present them as restricted cash and cash equivalents with the associated changes being included within cash flows from investing and financing activities. These balances cannot be used to satisfy operating or other liabilities. See Note 14, “Clearing Operations,” for further discussion of the default funds and margin deposits. Prior period amounts have also been adjusted to conform to current period presentation. This immaterial adjustment had no impact on our previously reported Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Income, or Condensed Consolidated Statements of Comprehensive Income. The table below presents a summary of the as reported and adjusted amounts relating to the Condensed Consolidated Statement of Cash Flows for the six months ended June 30, 2021.
Accounting Estimates	Accounting Estimates In preparing our condensed consolidated financial statements, we make assumptions, judgments and estimates that can have a significant impact on our revenue, operating income and net income, as well as on the value of certain assets and liabilities in our condensed consolidated balance sheets. At least quarterly, we evaluate our assumptions, judgments and estimates, and make changes as deemed necessary.
Stock Split	Stock Split In April 2022, we announced our plan to seek shareholder and SEC approval for an increase in the number of authorized shares of common stock in order to effect a 3-for-1 stock split of the Company’s common stock in the form of a stock dividend. In June 2022, we received the necessary approvals. In July 2022, our board of directors approved and declared the stock split in the form of a stock dividend. The record date for the stock dividend is August 12, 2022, with a distribution date of August 26, 2022 and we expect trading to begin on a split-adjusted basis on August 29, 2022.

These items, which are presented in the table below, include the following: • Amortization expense of acquired intangible assets: We amortize intangible assets acquired in connection with various acquisitions. Intangible asset amortization expense can vary from period to period due to episodic acquisitions completed, rather than from our ongoing business operations. As such, if intangible asset amortization is included in performance measures, it is more difficult to assess the day-to-day operating performance of the segments, and the relative operating performance of the segments between periods. Management does not consider intangible asset amortization expense for the purpose of evaluating the performance of our segments or their managers or when making decisions to allocate resources. Therefore, we believe performance measures excluding intangible asset amortization expense provide management with a useful representation of our segments' ongoing activity in each period. • Merger and strategic initiatives expense: We have pursued various strategic initiatives and completed acquisitions and divestitures in recent years that have resulted in expenses which would not have otherwise been incurred. These expenses generally include integration costs, as well as legal, due diligence and other third-party transaction costs. The frequency and the amount of such expenses vary significantly based on the size, timing and complexity of the transaction. Management does not consider merger and strategic initiatives expense for the purpose of evaluating the performance of our segments or their managers or when making decisions to allocate resources. Therefore, we believe performance measures excluding merger and strategic initiatives expense provide management with a useful representation of our segments' ongoing activity in each period. • Restructuring charges: We initiated the transition of certain technology platforms to advance our strategic opportunities as a technology and analytics provider and continue the realignment of certain business areas. See Note 19, “Restructuring Charges,” for further discussion of our 2019 restructuring plan. We believe performance measures excluding restructuring charges provide management with a useful representation of our segments' ongoing activity in each period. • Revenues and expenses - divested/contributed businesses: We have included in corporate items the revenues and expenses of our U.S. Fixed Income business, which was previously included in our Market Services and Investment Intelligence results. See “2021 Divestiture,” of Note 4, “Acquisitions and Divestiture,” for further discussion of this divestiture. Additionally, other revenues related to a transitional services agreement associated with a divested business are included in corporate items. Also included are the revenues and expenses associated with the NPM business, which we contributed in July 2021 to a standalone, independent company, of which we own the largest minority interest together with a consortium of third-party financial institutions. Prior to July 2021, these revenues were previously included in our Corporate Platforms results. • Other items:
