COVID-era volatility and meme-stock momentum drive demand for after-hours access. Retail platforms begin routing overnight.
24 Exchange files Form 1 to become the first SEC-registered 24-hour national securities exchange.
Nasdaq-powered overnight matching engine. Competes directly with BlueOcean.
OTC Markets subsidiary launches attributable overnight order flow. Third active U.S. overnight venue.
SEC grants 24X Exchange approval as a national securities exchange. Full 24-hour lit book for NMS securities.
24X begins live operations as the first SEC-registered 24-hour national securities exchange, launching with a limited set of mega-cap NMS symbols that expands over subsequent months.
First platform to aggregate and normalize data across all 3 overnight ATSs + the 24X national exchange.
DTCC's NSCC extends clearing to cover overnight trades in the same cycle as daytime. Removes the last systemic clearing-risk objection to institutional overnight participation.
SEC approves CTA and UTP Plan Amendments for 23x5 SIP operation (Sunday 9 PM through Friday 8 PM ET). Production launch December 6, 2026. Six industry UAT weekends begin October 2.
React to earnings, geopolitical events, and Asian market moves before the 9:30 AM open. Overnight trading eliminates the gap risk of holding positions through the closed session.
Overnight ATS data reveals institutional positioning before the bell. Understanding venue-level flow and timing differentials provides an informational edge for pre-market strategy.
Monitoring overnight venues is no longer optional. Reg NMS obligations, best execution requirements, and the expansion to 24 hours create new compliance surface area.
The bridge between on-chain and off-chain isn't coming. It is already here, processing institutional flow at scale on DTCC's Collateral AppChain, Canton, and Kinexys. RWA tokenization passed $26B in early 2026, tokenized Treasuries cleared $11B, and the GENIUS Act of 2025 codified the split between payment stablecoins and yield-bearing Investment Tokens. The 24-hour trading question is no longer just when the bell rings. It is how positions settle once it stops.
We track all overnight venues daily.
