Nasdaq is set to begin nearly 23-hour trading in U.S. stocks on December 6, 2026, introducing an overnight Night Session from 9 p.m. to 4 a.m. ET. The move, which follows regulatory approval earlier this year, extends trading from Sunday evening through Friday evening, with only a one-hour daily maintenance break between 8 p.m. and 9 p.m. ET.
The expanded schedule is widely seen as traditional finance borrowing from the cryptocurrency market's 24/7 structure. Nate Geraci, CEO of Novadius Wealth Management, noted on X that traditional exchanges are following crypto's model "whether they like it or not." Nasdaq President Tal Cohen described the change as a way to "broaden investor access and expand wealth-building opportunities."
Under the new framework, Nasdaq's existing 4 a.m. to 8 p.m. period becomes the Day Session, while the new Night Session runs from 9 p.m. to 4 a.m. ET. Eligible National Market System stocks and exchange-traded products can trade overnight, including securities primarily listed on other U.S. exchanges. The National Securities Clearing Corporation is providing 24-hour, five-day clearing availability to support overnight activity.
Brokerages will decide whether customers can access the overnight session. Nasdaq will mainly accept limit-priced orders during the Night Session, while market orders, pegged orders and auction-specific order types will not be available. Orders remaining on Nasdaq's book at the 4 a.m. boundary do not automatically roll into the Day Session.
To manage volatility, Nasdaq will implement temporary Phase 1 overnight price bands from 9 p.m. to 4 a.m., generally extending 20% around reference prices. Trades outside those ranges will be blocked. Regulators plan to review data from the first full quarter of overnight trading before proposing the next phase of the price-protection framework.
Observers note that while the extended hours offer more flexibility, overnight liquidity may be thinner, potentially leading to wider bid-ask spreads and higher volatility. The move underscores how crypto's always-on market culture is pressuring legacy institutions to adapt, even if Nasdaq's schedule is not fully 24/7.
