CME launches 24/7 Bitcoin futures; legacy gaps remain

CME Group began 24/7 trading for Bitcoin futures and several other cryptocurrency contracts on May 29, replacing the prior schedule that closed the regulated futures market on weekends. The weekend closures had produced visible price gaps on CME charts since December 2017; three legacy gaps remain near $80,000, $78,500 and roughly $67,000–$70,000.

The exchange extended continuous trading to Bitcoin, Ether, Solana and six other contracts. Daily maintenance windows are two minutes on weekdays and two hours on Saturdays. The change allows portfolio managers, ETF issuers and corporate treasuries to adjust positions on a regulated venue during weekend market moves.

Under the old schedule, futures closed on weekends while spot and perpetual markets kept trading. When futures reopened after a weekend swing, the opening price often left a gap between the previous close and the new open. Historical data show gaps were filled between about 70% and over 90% of the time, often within days or weeks. Traders frequently used gap fills as short-term price targets.

CME’s announcement attributed the change to client demand for risk management. Tim McCourt, CME Group’s Global Head of Equities, FX and Alternative Products, is quoted saying client demand for risk management is “at an all-time high” and citing $3 trillion in notional volume across CME cryptocurrency futures and options in 2025.

Market activity during the first continuous-trading weekend was muted. Bitcoin traded near $73,441 on Sunday, down about 3.7% for the week. Two legacy gaps sit above the current price near $78,500 and $80,000, and one gap remains below in the $67,000 to $70,000 range.

CME plans to launch Bitcoin Volatility futures on June 1, a contract that will track 30-day implied volatility. Early session volume and changes in open interest in the continuous futures will be monitored as indicators of how quickly institutional participants and ETF issuers adopt the new hours and adjust hedging activity.

Analyst Daan Crypto Trades wrote that the remaining gaps will still appear on charts and that no new weekend gaps will form under 24/7 trading. Traders and institutional participants will watch whether existing gaps continue to attract price action now that weekend gaps have ended.
