Bitcoin futures open interest hit $79 billion as options show a bullish skew, though short-term volumes indicate hedging. Hedge funds are net long CME
Bitcoin futures open interest has climbed to $79 billion, signaling significant trader positioning, while options markets show a bullish skew with call contracts dominating open interest [1, 3]. This surge in derivatives activity coincides with Bitcoin trading near all-time highs, around $77,419 [3]. Hedge funds, for the first time in years, have flipped to a net long position on CME Bitcoin futures, a move typically indicating a direct bullish bet rather than a market-neutral strategy [2].

Total Bitcoin futures open interest stands at 692,490 BTC, equivalent to $79 billion, with the CME accounting for $15.88 billion and Binance for $13.87 billion [1]. This build-up has occurred alongside Bitcoin's price appreciation in 2025, which is currently trading about 5% below $120,000 [1]. On the options front, open interest is near $60 billion, with call contracts representing 61.43% of the total, suggesting a longer-term bullish outlook [1]. Deribit leads the options market, with a notable $140,000 strike call for December 2025 holding significant open interest [1].
However, recent 24-hour options volumes show a shift towards puts, indicating short-term hedging activity despite the overall bullish bias [1]. Traders have been actively buying short-dated put options, particularly those with strikes around $112,000 and $115,000, pushing near-term implied volatility higher [1]. This suggests traders are preparing for potential short-term turbulence even as longer-term sentiment remains optimistic [1].
While hedge funds are signaling bullishness through CME futures, data on actual Bitcoin demand presents a mixed picture. The Coinbase Premium Index, a gauge of U.S. institutional demand, has remained below zero since early May and has shown lower highs and lows since late July, indicating soft institutional buying of actual coins [2]. This contrasts with the bullish futures positioning, suggesting a split between paper bets and on-the-ground buying [2]. Furthermore, overall open interest across all exchanges is near $23 billion, close to the lowest level of the past year, which suggests limited new money entering the market and caps the potential for sharp rallies while also limiting downside risk [2].
The current derivatives market configuration, characterized by high notional exposure and a bullish open interest skew, coupled with short-term hedging activity, indicates that while traders anticipate further upside, they are also positioning for potential near-term price fluctuations.
