May 28th brings a critical update for crypto derivatives: the Chicago Mercantile Exchange (CME) will launch 24/7 trading for Bitcoin futures and options this Friday, with only a 1-hour system maintenance window each Sunday between 22:00 and 23:00 UTC. This change will effectively eliminate the long-watched "CME gap" phenomenon. Previously, CME Bitcoin futures paused trading from Friday’s close through Sunday, while the broader Bitcoin spot market operated nonstop. This disconnect regularly formed what traders call a "CME gap," spurring widespread "gap-filling" trading strategies. Analysts view this move as CME continuing to align with crypto’s native 24/7 market structure, which will reduce institutional exposure to weekend risk and enhance hedging efficiency. However, institutional liquidity remains concentrated in ETF options and offshore perpetual futures contracts, per industry observations.

On May 28, Coinglass data shows that if Bitcoin drops below $72,000, cumulative long liquidation intensity across major centralized exchanges (CEXs) will reach $807 million. Conversely, if Bitcoin surpasses $75,000, cumulative short liquidation intensity on major CEXs will hit $1.058 billion. BlockBeats Note: Liquidation charts do not display the exact number of contracts set to liquidate or their precise value. The bars on these charts represent the relative importance of each liquidation cluster compared to adjacent clusters—this is what’s referred to as "intensity". Therefore, the chart illustrates how significantly an underlying asset’s price will be impacted when it reaches a specific level. A higher "liquidation bar" means once the price hits that level, it will experience a more intense reaction due to a liquidity cascade.
