Nasdaq proposes nearly 23-hour U.S. stock trading, targeting a Dec. 6, 2026 start
Nasdaq plans to extend U.S. stock trading to nearly 23 hours a day, five days a week, adding an overnight session from 9 p.m. to 4 a.m. ET. The exchange expects the schedule to begin on December 6, 2026, subject to U.S. Securities and Exchange Commission approval and readiness of the securities information processor. Nasdaq also plans risk controls such as static price bands to reject orders outside set limits. The move is aimed at meeting rising global demand for U.S. equities.
