- CME will switch its crypto futures and options to 24-hour trading on Friday, ending a mismatch with bitcoin’s nonstop spot market.
- The change hurts the well-known “CME gap” trade, where traders looked for price gaps when the exchange was closed over the weekend.
- Liquidity isn’t all in one spot. ETF options and offshore perpetual futures are still bigger pools for some crypto volatility trades.
CME Group will start round-the-clock, seven-day trading for its cryptocurrency futures and options on Friday. The shift ends a weekend gap that bitcoin traders have watched for years. CME’s crypto contracts will now trade more like the spot market, which runs without pause.
CME gaps are getting more attention from traders now. These gaps show up when spot bitcoin trades while CME futures are closed, leaving a price break between Friday’s close and Sunday’s open. Futures then have to catch up when trading starts again.
CME said it will start offering crypto futures and options 24/7 on Globex and ClearPort from May 29 at 4:30 p.m. Central Time. After launch, crypto markets on the exchange open at 4:02 p.m. CT every Friday. There are still maintenance windows, including a two-hour outage on Saturdays.
CME’s global head of equities, FX and alternative products, Tim McCourt, said “client demand for risk management” in digital assets hit an all-time high. CME reported its crypto futures and options saw record notional volume of $3 trillion in 2025. Average daily volume so far in 2026 is up 46% to 407,200 contracts. CME Group
Bitcoin hovered around $73,543 early Friday, steady compared to Thursday, market data showed. Ether was near $2,006.
CME’s change means institutional traders can now hedge over the weekend. Weekend trades will still clear, settle, and report on the next business day, the exchange said, but futures exposure can be adjusted after weekend news without waiting for the Sunday night open.
CME is pitching the change as a response to weekend volatility, rather than just making trading easier. In an April paper, the exchange pointed out that bitcoin volatility doesn’t let up on weekends. CME cited a March 2025 episode where the announcement of the U.S. Strategic Crypto Reserve sent spot markets moving while futures were closed, creating a $10,000 bitcoin futures gap.
The old trade is still sticking around. CoinDesk says there are three CME gaps left this year: two above spot bitcoin, close to $80,000 and $78,500, and another sitting under $70,000.
Liquidity is the bigger risk here. Cole Kennelly, who runs Volmex Labs, told CoinDesk BlackRock’s IBIT ETF options carry open interest between $27 billion and $30 billion, while CME bitcoin futures options sit much lower, at $800 million to $900 million. Open interest tracks how many contracts are still open and not settled.
Crypto-centric venues remain in play. BTCC pushes futures and spot pairs, plus copy trading and demo trading to retail, while Phemex is out with bitcoin trading education content, including guides on chart patterns like “three white soldiers,” a setup made up of three rising candles. CME is entering a space shaped by these types of venues, though CME’s case is a regulated exchange instead of a retail platform. FindArticles Phemex
But weekend price moves may stick around. CME’s maintenance break still brings brief halts, and light liquidity during those gaps could spark sharp swings. Offshore perpetual futures—futures-style contracts without an expiry—and ETF options are likely to guide the market tone when big players seek more depth.
CME has smoothed out a friction point for now. Next up is seeing if traders actually move enough volume into the weekend sessions to make the market function, instead of just being technically open.
