NASDAQ officially announced that the 23-hour trading system (23/5) will be launched on December 6, 2026, and has already received approval from the U.S. Securities and Exchange Commission (SEC). At that time, the U.S. stock market will close for only 1 hour each day (20:00–21:00 Eastern Time) for system clearing and data processing, while trading will remain continuously open for the rest of the time.

Alright, U.S. stock traders don’t have to rest anymore.
