Nasdaq Files With SEC to Extend U.S. Stock Trading to 23 Hours, Five Days a Week

A second-half 2026 start depends on SEC approval plus key clearing and data upgrades.

Overview

  • The proposal creates two weekday sessions: a 4 a.m.–8 p.m. ET day session and a 9 p.m.–4 a.m. ET night session, separated by a one-hour maintenance break.
  • Trades executed between 9 p.m. and midnight would be recorded for the following trading day, with the week running from Sunday 9 p.m. to Friday 8 p.m.
  • Nasdaq cites growing global demand for U.S. equities, noting foreign holdings of U.S. stocks at roughly $17 trillion and rising overnight interest from Asia and other regions.
  • A full rollout requires enhancements to the securities information processor and nonstop clearing at DTCC, which is scheduled to enable 24/7 stock clearing by the end of 2026.
  • NYSE and Cboe have outlined similar moves toward near-continuous trading, while major banks caution about thinner liquidity and greater volatility during overnight sessions.
