Crypto never sleeps. As of May 29, CME Group’s crypto futures and options don’t either.

The world’s largest derivatives exchange flipped the switch on 24/7 trading for its entire crypto futures suite at 4:30 p.m. CT, eliminating the weekend closures and limited hours that had defined its digital asset offerings since launch. The move covers futures and options on nine assets: Bitcoin, Ethereum, Solana, XRP, Cardano, Chainlink, Stellar, Avalanche, and Sui.

For years, institutional traders had access to crypto futures on a regulated exchange, but only during what amounted to a near-23-hour daily window, with full shutdowns on weekends. That meant price gaps every Monday morning, commonly known as “CME gaps,” which became something of an obsession for chart analysts tracking support and resistance levels. Those gaps are now, for practical purposes, extinct.

What the new trading schedule looks like

On weekdays, there’s a two-minute maintenance window between 4:00 and 4:02 p.m. CT. On weekends, a longer two-hour maintenance window runs from 2:00 to 4:00 a.m. CT on Saturdays.

Any trades executed during weekends or holidays will receive the next business day’s settlement date. So the trading is continuous, but the back-office plumbing still operates on traditional finance time.

The numbers behind the timing

Year-to-date average daily volume across CME’s crypto futures hit 407,200 contracts, a 46% increase compared to the same period last year. Open interest stood at 335,400 contracts at the time of the launch.

The open interest figure of 335,400 contracts tells a complementary story. High open interest relative to volume suggests positions are being held over longer time horizons rather than day-traded.

Why this matters for Ethereum and the broader market

The elimination of CME gaps also has implications for market microstructure. Those gaps frequently created artificial volatility at the weekly open, as futures prices snapped to match where spot markets had traded over the weekend. Removing that discontinuity should lead to smoother price discovery and tighter correlations between CME futures and underlying spot prices.
