Chicago Board Options Exchange Global Markets Inc. announced that the U.S. Securities and Exchange Commission (SEC) has approved its application, allowing extended trading hours for certain options on multi-market listed stock contracts. This is another important step by Cboe in advancing the U.S. market toward “near around-the-clock trading.”
Cboe Options Exchange plans to officially launch extended trading hours on July 13, 2026. The added trading sessions will cover two time windows from Monday to Friday: pre-market trading from 7:30 a.m. to 9:25 a.m. Eastern Time, and after-hours trading from 4:00 p.m. to 4:15 p.m. Eastern Time.
To ensure market liquidity, Cboe has set strict eligibility thresholds for options to be included in the extended trading hours: average daily trading volume of no less than 150,000 contracts over the past six months, underlying stock market capitalization of at least $50 billion, and average daily trading volume of no less than 10 million shares for the underlying stocks. Based on the above criteria, Cboe expects that at the initial stage, about 20 highly liquid stock options will be available for trading, including tech stocks from the “Magnificent Seven” and popular names such as Palantir, Broadcom, and AMD. Cboe plans to update the list of securities eligible for trading every six months.
Meaghan Dugan, head of Cboe’s U.S. derivatives business, said: “Today’s SEC approval is an important milestone for the U.S. options industry. We are taking a phased approach—starting with certain single-underlying options—to ensure that market protection mechanisms and investor protection measures always remain effective.”
Cboe currently provides near around-the-clock 5-day trading services in its global trading hours for proprietary index options and in after-hours trading, covering S&P 500 index options and Cboe Volatility Index options. In the first quarter of 2026, trading volume during these two trading sessions increased by 32% compared with the same period in 2025, partly driven by strong demand from Asia-Pacific clients.
In the U.S. equities business, Cboe currently provides trading services from 4:00 a.m. to 8:00 p.m. Eastern Time on two of its four exchanges. The company also plans to launch a U.S. stock trading service on its Cboe EDGX stock exchange this December—5 days a week, 23 hours a day—and it is still awaiting regulatory approval.
Analysts point out that as U.S. stock trading gradually moves toward the “23×5” and even “24×5” trading era, the mismatch between options trading hours and underlying stock trading hours has become increasingly prominent. This move by Cboe will help investors better manage position risk during major events, especially by avoiding “reverse exercise risk” caused by unexpected after-hours events. $AMD
