Overview
- CME began round‑the‑clock trading for Bitcoin futures and options on Friday, May 29, with a scheduled weekly 60‑minute maintenance pause on Sundays and other short operational pauses.
- The continuous hours remove the regular Friday‑close-to‑Sunday‑reopen price discontinuity known as the CME gap, though three historical gaps from earlier this year near $80,000, $78,500 and just under $70,000 remain open.
- Trades executed on weekends and holidays will still carry the next business day’s trade date for clearing, settlement and reporting, so back‑office timing conventions have not changed.
- CME’s structural shift gives asset managers and traders the ability to hedge and adjust positions at any hour, but liquidity leadership still sits with ETF‑linked options and offshore perpetual markets where open interest is far larger.
- The move follows heavy institutional derivatives use in 2025 and may narrow weekend risk premiums over time, though short‑term volatility at maintenance reopens and existing liquidity concentrations mean market dynamics could take weeks to settle.
