Cboe has filed a proposal with the U.S. Securities and Exchange Commission to operate near 24x5 trading on its EDGX Equities Exchange, aiming for a December 2026 start if regulators approve. The plan would expand trading to run from Sunday night through Friday evening with a daily one-hour operational pause, part of a broader push by exchanges to meet rising investor interest in extended-hours access.

Key Points

  • Cboe filed with the SEC to run near 24x5 trading on its EDGX Equities Exchange, targeting a December 2026 start pending approval - impacts exchanges, equities markets and trading platforms.
  • Proposed hours would extend trading from Sunday 9:00 p.m. ET through Friday 8:00 p.m. ET with a one-hour pause nightly Monday-Thursday - affects market participants who trade outside regular hours.
  • Cboe reports a 590% increase in average daily volume from February 2022 to February 2026 and already operates limited early-morning sessions on two of its four exchanges - relevant to liquidity and market infrastructure.

On March 16, exchange operator Cboe disclosed that it has submitted a formal proposal to the U.S. Securities and Exchange Commission to launch near 24x5 trading for U.S. equities on one of its platforms. The proposed program would run on the firm's EDGX Equities Exchange and is subject to regulatory approval.

Under the plan outlined in the filing, trading would be available from Sunday at 9:00 p.m. ET through Friday at 8:00 p.m. ET, with a recurring one-hour operational pause between 8:00 p.m. and 9:00 p.m. ET from Monday through Thursday. Cboe has targeted December 2026 as the launch month, contingent on clearance from the SEC and coordination with other industry participants.

This filing is part of a broader competitive push among exchanges to capture increased investor demand for continuous trading. A peer exchange has said it planned to submit paperwork to pursue round-the-clock trading as well, highlighting an industry-wide effort to expand hours for U.S. stocks.

"Cboe’s filing with the SEC is the latest step in ensuring we are ready to offer overnight trading once the industry launches in December," Oliver Sung, head of North American Equities, said in a statement.

Cboe noted marked growth in activity ahead of the filing: average daily volume on its platforms rose by 590% from February 2022 to February 2026. The operator already runs limited extended sessions, offering trading between 4:00 a.m. ET and 7:00 a.m. ET on two of its four exchanges.

In addition to equities trading services, Cboe provides markets for derivatives and volatility products, including instruments tied to its flagship VIX volatility index, a widely referenced gauge of market volatility.

The filing and the stated launch timeline highlight two immediate dependencies: regulatory approval from the SEC and broader industry coordination to initiate extended continuous trading in December. Cboe’s statement frames the submission as a preparatory step to align systems and operations for overnight activity should the industry proceed as planned.

Separately, market-focused tools and advisory services have pointed to broker and exchange listings as areas investors may evaluate. For example, a market analysis product described its process for assessing the exchange operator ticker NDAQ and highlighted historical model winners in other coverage, naming Super Micro Computer (+185%) and AppLovin (+157%) as past examples of the model’s picks.

The proposal represents a material operational change for U.S. equities markets and adds to existing debate among market participants and regulators over the implications of substantially extended trading hours.

Risks

  • Regulatory approval remains pending - the launch on EDGX is contingent on SEC clearance and therefore uncertain, affecting the exchanges and equities trading sector.
  • Industry coordination is required for the planned December launch - the timeline depends on broader market participants aligning to support continuous trading, creating execution risk for operators and brokers.
  • Operational readiness and systems integration will be necessary to support overnight trading - exchanges and infrastructure providers face technical and operational challenges tied to extended hours.
