Hedge Funds Unwind Bitcoin Basis Trade Amidst Diminished Futures Premium

Recent developments on Wall Street demonstrate a decrease in the popularity of the Bitcoin basis trade among hedge funds. Data shows that these funds have drastically decreased their net short positions in CME Bitcoin futures, slashing them by 89% since December 2024.

CME Futures Positions Decline

As of November 3, 2026, leveraged funds reported a net short position of 2,591 contracts, corresponding to about 12,955 BTC. This figure represents the lowest level since February 2023.

Understanding the Basis Trade

The basis trade can be conceptualized as analogous to buying concert tickets at their original price and then selling them on a secondary market for a profit. The gain originates from the disparity in prices, rather than the quality of the event itself.

In the cryptocurrency sphere, a fund can maintain exposure through a spot exchange-traded fund (ETF) while shorting CME futures at a premium. This strategy allows the fund to capitalize on the price convergence between futures and spot prices as the contracts approach expiry, without concerning itself with Bitcoin’s market direction.

However, the basis has significantly contracted, currently sitting at just 4.8% annualized. This limited spread offers returns that barely exceed the yields from U.S. Treasury securities, leading many sophisticated investors to reconsider the complexity of their trades.

Changes in ETF Exposure

Moreover, several multi-strategy hedge funds, such as Millennium Management and Brevan Howard, have also diminished their exposure to spot Bitcoin ETFs. Between September 2025 and June 2026, nine hedge funds collectively reduced their holdings by approximately 68,000 BTC, equating to a valuation of about $5.4 billion.

Thinning CME Futures Activity

The reduction in hedge fund activity is echoed in CME Bitcoin futures, where open interest dwindled to about 17,527 contracts (approximately 87,635 BTC) by early November 2026, alongside a decrease in trading volume.

Recent Market Trends

Interestingly, in August 2026, leveraged funds briefly shifted to a net long position in CME Bitcoin futures for the first time. This marked a notable deviation from the typical trend, wherein these funds served as structural short sellers, largely due to the prevailing dynamics of the basis trade. Some analysts suggest this shift could indicate growing bullish sentiment around Bitcoin.

The Rise and Fall of the Basis Trade

The basis trade gained traction after the introduction of spot Bitcoin ETFs, which provided a more approachable method for institutional investors to engage in the market. By pairing ETF shares with CME futures shorts, funds had a streamlined way to benefit from Bitcoin’s futures premium.

The peak interest recorded in December 2024 highlighted the strategy’s effectiveness. However, as the premium has reduced over time, both ETF stakes held by multi-strategy funds and the short positions in the market have considerably decreased.

Implications of the Current Landscape

The current landscape of net short positions reflects levels not seen since February 2023, indicating a regression to market conditions before the ETF-driven surge in carry trades.

This shift complicates the interpretation of ETF flow data. Historically, a significant proportion of ETF purchasing was attributed to funds hedging their positions, lacking a robust bullish or bearish outlook on Bitcoin. As this hedging activity declines, ETF flows may begin to represent a more accurate measure of genuine demand, rather than an arbitrage strategy.

Conversely, some recent ETF outflows may not necessarily indicate bearish market sentiment. When funds divest from ETF shares and simultaneously close out futures shorts, they may be unwinding a spread trade instead of expressing a lack of confidence in Bitcoin’s value.

Future Considerations

The primary aspect to monitor is the basis itself. With the basis currently at an annualized 4.8%, the potential earnings from the trade are almost equal to those of U.S. Treasuries. Should the premium widen again, it could revive the economics of the carry trade and attract hedge funds back into the futures market.
