Cboe Global Markets has filed a proposal with the US Securities and Exchange Commission (SEC), with the aim of launching near 24/5 equities trading on its Cboe EDGX Equities Exchange (EDGX).

The new offering will enable all listed NMS stocks which are currently traded on EDGX to be expand to market hours running from 9pm ET on Sunday to 8pm ET on Friday, including a one-hour operational pause from 8pm to 9pm ET Monday to Thursday.
The launch is currently scheduled to go live in December 2026, subject to regulatory approval and the readiness of the industry infrastructure providers required for the shift.
“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,” said Oliver Sung, head of North American equities at Cboe.
“Since announcing our plans for near 24/5 trading amid growing global interest for US markets, we have been engaging with clients and market participants across the globe, underscoring the importance of collaboration throughout this process.”

In addition, all trades within these extended market hours will be cleared through the Depository Trust and Clearing Corporation (DTCC).
Cboe has also highlighted that the shift to this new model for EDGX will require increased market access and high-quality real-time data.
To prepare for this, the firm is continuing its expansion of its Cboe One US equities feed, which collates and provides access to consolidated market data from the firm’s four US equities exchanges: BZX, BYX, EDGX and EDGA.
“Cboe understands that accurate and reliable market data is the foundation for making informed investment decisions,” said Brian McElligott, head of Cboe Data Vantage.
“We continue to focus on expanding the availability of our US equities data offerings, reflecting the strong desire for access to US markets from Europe and APAC investors.
The new offering reflects a growing demand for expanded trading hours for US equities across the industry. Currently, Cboe offers trading from 4am ET to 7am ET on two of its four exchanges – EDGX and BZX.
Similarly, in January 2026, the DTCC announced that it was launching an industry-wide testing phase for 24/5 trading, to prepare for numerous shifts to extended market hours set to come into play across the industry in the coming months.
Notably, in December 2025 Nasdaq submitted a filing to the SEC to extend to a 23/5 trading hours model for US equities and exchange-traded products (ETPs).
