Bitcoin’s derivatives market has just undergone its largest weekly deleveraging in roughly a year, with combined open interest across CME Bitcoin futures and perpetual futures falling by approximately 49,000 BTC over the past seven days. According to CoinGlass, total Bitcoin futures open interest stood at about $52.89 billion, while Bitcoin traded near $84,070 and 24-hour futures volume reached $56.25 billion.
Unlike previous sharp leverage reductions, this reset occurred quietly. Only about $67.6 million in Bitcoin futures liquidations were recorded over the previous 24 hours, a relatively small figure compared with the broader open-interest base. Perpetual-futures funding rates also cooled, and Bitcoin volatility remained contained, suggesting the decline was driven largely by voluntary position unwinding and profit-taking rather than cascading margin calls.
One important nuance is the expiration of CME’s September Bitcoin futures contract on September 25, which sits inside the seven-day measurement window. That means part of the CME-linked open interest decline is mechanical and should not automatically be read as institutions abandoning Bitcoin exposure. Analyst Vetle Lunde noted that every larger open-interest drop in the past came with substantial liquidations, whereas this episode resembles good old profit realization.
The current setup contrasts sharply with the October 10, 2025 liquidation event, when more than $9.55 billion in open interest was erased and total crypto liquidations exceeded $19 billion within 24 hours. Market participants are now watching the start of the October CME contract cycle and the upcoming U.S. non-farm payrolls report on Friday for the next directional cues.
