Nasdaq, NYSE Arca, and Cboe are racing toward 23-hour equity trading. The DTCC is upgrading clearing infrastructure by mid-2026 to support it. Crypto's 24/7 edge narrows.
Nasdaq secured SEC approval on April 10 for what it calls "Global Trading Hours," a 23-hour-a-day, five-day-a-week window for US equities. The exchange targets a Q3 2026 rollout. NYSE Arca has penciled in December 6 for its own 23-hour session, pending final sign-off. Cboe is pursuing similar extended-hours capabilities.
The DTCC's National Securities Clearing Corporation, the entity that settles stock trades, is upgrading its clearing infrastructure by mid-2026 to support these longer trading days. Charles Schwab already offers 24/5 trading across more than 1,100 stocks and ETFs, a feature it rolled out during 2024 and 2025.
The difference is scale and market structure. Retail platforms offering after-hours trading typically route orders through alternative trading systems with thinner liquidity and wider spreads. When Nasdaq and NYSE go 23 hours, the primary exchanges themselves stay open, with full order books and the kind of liquidity institutional players require.
The driving force is global demand, particularly from the Asia-Pacific region. When it is mid-afternoon in Tokyo or Sydney, US markets are dark. That forces international investors to either wait or trade through less liquid channels.
NYSE is taking things a step further with a blockchain-based tokenized securities platform designed to enable genuine 24/7 trading and instant settlement for US stocks and ETFs. Overnight trading volumes are projected to climb to as much as 10% of total market activity by 2028 as these structural changes take effect.
For the crypto market, TradFi's embrace of continuous trading validates the infrastructure model that crypto pioneered. It also creates a more natural bridge between traditional and digital asset markets, as tokenized securities blur the boundary between the two worlds. The crypto market analysis page tracks how these shifts affect digital asset volumes and spreads.
A repeat reader should learn meaningfully more than the wire summary contained. The wire told you what happened. This tells you the mechanism: the clearing upgrade, the liquidity difference between primary and alternative venues, and the specific regional demand that is driving the change. The next concrete marker is the DTCC's mid-2026 clearing upgrade. If that slips, the exchange rollouts slip with it.
