Cboe Wins SEC Approval for 23x5 U.S. Stock Trading on EDGX, Targets December 2026 Launch

December 2026 is Cboe’s target to start 23x5 U.S. equities trading on its EDGX exchange after winning SEC approval, with the rollout still dependent on industry readiness.
EDGX would trade all listed NMS stocks from Sunday 9 p.m. ET to Friday 8 p.m. ET, pausing one hour each weeknight from 8 p.m. to 9 p.m. ET.
DTCC is slated to clear the trades, extending Cboe beyond its current 4 a.m. to 8 p.m. ET equities session on two of its four U.S. stock exchanges.
Cboe said demand for off-hours U.S. trading has grown since EDGX added early trading in 2021, led especially by Asia-Pacific retail investors seeking to react to news in real time.
The move also supports Cboe’s push to sell more global market access and real-time data, including its Cboe One equities feed, to clients in Singapore, Hong Kong and Tokyo.
Is this push for 24-hour trading the final step before Wall Street fully embraces 24/7 tokenized, blockchain-based securities?
Is the race to 24-hour trading for investors, or a battle between exchanges for global data revenue and market share?
