Nasdaq has confirmed Dec. 6 of this year as its target date for a nearly 23-hour trading day, adding a 9 PM to 4 AM ET overnight session five days a week in a bid to match markets, including crypto, that never fully close.
Key Takeaways
Nasdaq targets Dec. 6, 2026 to launch a 9 PM-4 AM ET overnight session, nearing a 23-hour trading day.The SEC approved Nasdaq’s core 23/5 proposal in early Q2 2026, though implementation safeguards still need sign-off.Just 2% of Nasdaq volume trades outside standard hours today, even as CME already runs 23-hour futures.Nasdaq’s existing regular session, 9:30 AM to 4 PM ET, would stay unchanged and continue to set the prices the rest of the market treats as authoritative.
Friedman also said the exchange is making sure that consolidated tape and market data will be available by then, producing what she called a more “lit market environment 23/5”.
Regulatory Sign-off Still PendingNasdaq also plans new safeguards for the overnight session, including static price bands that would automatically reject orders placed outside specified limits, another element still awaiting regulatory sign-off. Traders who want to participate overnight will need new order entry ports, and some order types will not be available during the extended hours.
For an exchange operator like Nasdaq, matching that cadence for stocks themselves, even short of full weekend trading, is as much a competitive response as a technical one, since capital increasingly treats round-the-clock access as the default rather than the exception.
