| 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 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.
|
| 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 revenues, 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 Events | Subsequent Events We have evaluated subsequent events through the issuance date of this Quarterly Report on Form 10-Q. See Note 4, “Divestitures” and “Variable Notional ASR Agreement,” of Note 11, “Nasdaq Stockholders’ Equity” for a discussion of subsequent events.
