The SEC approved CBOE’s plan to begin extended trading hours for select
single-stock options on July 13, 2026. The initial rollout will cover roughly 20
highly liquid names, including all seven largest US tech stocks. CBOE also plans
to launch 23x5 US stock trading on its EDGX exchange in December to broaden
round‑the‑clock access. Eligibility for extended-hours options requires at least
150,000 contracts open interest, market cap above $50 bln and average daily
share volume exceeding 10 mln.
