CME Group has launched 24/7 trading for Bitcoin futures and options on its Globex platform, effectively eliminating the famous CME weekend gap that has long been a structural inefficiency in Bitcoin markets. Previously, CME futures closed on Friday and reopened on Sunday, creating a predictable price gap that traders exploited. The new schedule includes only a two-hour maintenance window each Saturday, reducing weekend risk premia and improving hedging efficiency for institutional participants. However, three unresolved gaps from earlier this year remain, with two above the current spot price near $73,000 and one below. Despite this shift, CME Bitcoin futures options open interest ($800-900 million) is still dwarfed by BlackRock's IBIT ETF options ($27-30 billion), and offshore perpetual futures and ETF options are expected to retain dominance. The change marks progress toward fully integrated institutional crypto markets.
