Cboe postponed the expanded-hours launch for selected equity options that was due to begin today (Monday). The exchange removed the August 17 start date and has not announced a replacement.
Until Cboe sets a new date, traders cannot use the planned session to trade listed options on Nvidia, Apple, Tesla and other heavily traded stocks before Wall Street opens. The missing window also delays an exchange-based source of implied volatility and options flow during the equity premarket.
The postponement is separate from Cboe’s proposal to bring near 24-hour stock trading to its EDGX equities exchange. That project targets December 2026, subject to regulatory approval and industry readiness.
August 17 Launch Replaced With TBD
Cboe Options Exchange (C1) changed the start date to “TBD” in an August 10 schedule update. It also removed dates for two planned customer weekend tests and said another notice would precede the launch.
