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.
