Discontinued Operations and Disposal Groups [Abstract]
Divestitures	Divestitures In January 2025, we entered into an agreement to transfer existing open positions in our Nordic power futures business to a European exchange. In June 2025, this transaction was completed and consideration was received. Migration of open positions are planned to take place by the end of the first quarter of 2026. We expect to wind down the commodities clearing and trading services by the end of the second quarter of 2026, and the business to be wound down in the months following. In connection with the successful migration of open positions, Nasdaq may receive additional consideration in 2026 and 2027, and is expected to release regulatory capital in the medium term. In April 2025, Nasdaq completed the sale of our Nasdaq Risk Modelling for Catastrophes business previously included in Capital Markets Technology within our Financial Technology segment. The impact of the transactions, net of costs to sell, described above are included in net gain (loss) on divestitures in the Condensed Consolidated Statements of Income. In September 2025, Nasdaq entered into an agreement to sell Nasdaq Solovis to a global software investor, which subsequently closed in October, and resulted in a gain which will be recorded in the fourth quarter of 2025. The Nasdaq Solovis business is included in Workflow & Insights within our Capital Access Platforms segment.
