Nasdaq has set Dec. 6 as the target date to launch an overnight trading session from 9 p.m. to 4 a.m. Eastern Time, five days a week, creating a nearly 23-hour trading day that brings U.S. equities closer to the always-on model of cryptocurrency markets.
What’s changing
The exchange plans to add a new overnight session to its existing premarket, core, and after-hours trading windows. With only a one-hour pause each weekday evening, Nasdaq would operate almost continuously from Sunday night through Friday.
- Core session: 9:30 a.m.–4:00 p.m. ET
- After-hours: 4:00 p.m.–8:00 p.m. ET
- New overnight: 9:00 p.m.–4:00 a.m. ET
- Premarket: 4:00 a.m.–9:30 a.m. ET
- Daily pause: 8:00 p.m.–9:00 p.m. ET
Why it matters for crypto-linked markets
Cryptocurrencies trade continuously, and price moves often occur outside traditional U.S. equity hours. By extending its schedule, Nasdaq narrows the gap between digital asset markets and listed equities, potentially improving price discovery and risk management for crypto-exposed stocks and exchange-traded products when significant news breaks overnight.
Market implications
Near round-the-clock trading could help investors respond to earnings releases, macroeconomic data from Asia and Europe, and other events that unfold outside the U.S. day. Actual liquidity and spreads during the new session will depend on broker and market-maker participation. The change underscores the gradual shift in market structure toward continuous electronic access, reflecting investor expectations shaped by 24/7 crypto trading.
Effective date
Nasdaq’s target start date for the expanded hours is Dec. 6, operating Monday through Friday.
