SEC Approves First U.S. Stock Exchange With 23-Hour Trading

The 24X National Exchange, backed by Point72 Ventures, plans to launch in 2025 with extended trading hours to address global market demands.

The SEC has approved the 24X National Exchange to operate nearly continuously, allowing trading 23 hours a day, five days a week, starting in the second half of 2025.
Initial trading hours will run from 4 a.m. to 7 p.m. ET, with plans to expand to overnight trading from Sunday evening to Friday evening, pending additional regulatory benchmarks.
The exchange aims to provide broader access for both institutional and retail investors, particularly addressing demand for overnight liquidity in the Asia-Pacific region.
Proponents argue that extended hours will enable faster reactions to global events, but critics warn of potential risks like lower liquidity and unfavorable pricing during off-peak times.
This development aligns with a growing trend in U.S. markets, as other platforms, including Robinhood and NYSE, explore or expand extended trading windows.
