24X Pushes Overnight Market-Session Filing Deadline to December 2026

24X National Exchange has filed to push back the deadline for its separate market-session rule proposal, moving the date from May 27, 2026 to December 27, 2026. The request, published in the Federal Register on May 19, would give the venue seven more months before it has to submit the filing that would govern the start of its planned 24X Market Session.

That matters because the delayed filing is the key next step for 24X’s proposed overnight equities session, which the exchange has described as running from 8:00 p.m. to 4:00 a.m. Eastern Time on Sunday through Thursday nights. In the filing, 24X said the extra time is needed because the equity data plans still need to update their systems so they can collect, consolidate, process, and disseminate quote and trade data during those extended hours.

In other words, this is not a launch delay caused by trading demand. It is a market-plumbing issue. Without concurrent SIP support, the exchange cannot practically turn on an overnight session that depends on consolidated market data and the broader post-trade ecosystem.

Why it matters

For traders watching the push toward exchange-based overnight stock trading, the filing shows that market-structure ambition is moving faster than the supporting infrastructure.

What to watch next

Watch whether the SEC lets the extension stand and whether 24X files the market-session proposal well before the new December 27 deadline. The bigger signal will be how quickly SIP and clearing dependencies catch up.
