Analysts Say Negative Bitcoin Futures Funding Reflects Institutional Hedging, Not Bearishness

After Bitcoin fell below $75,000 in late May, $70,000 became a key line of defense for bulls. Funding rates turned positive and open interest remained elevated, signaling an influx of leveraged long positions. Bitfinex said, however, that U.S. spot ETFs have replaced some direct buying on Coinbase, making ETF flows an important gauge of institutional demand.

As of a May 28 report, U.S. spot ETFs recorded more than $200 million in daily net outflows and over $1.5 billion across seven days. Global open interest fell below $55 billion, down 14% from when Bitcoin traded above $80,000. On June 22, the annualized funding rate rose to a nearly three-week high of 7%, but CoinGlass data showed ETFs still posted $228 million in net outflows over the preceding week, weighing on momentum for a rebound to $70,000.

Bitcoin perpetual futures use funding rates to keep contract prices aligned with the spot market. Negative rates generally mean short sellers pay long holders. K33 Research and market maker Caladan said the latest negative readings largely reflect delta-neutral positions used by hedge funds, basis traders and miners to hedge exposure to spot Bitcoin, Strategy shares or corporate Bitcoin reserves. That suggests derivatives short positions do not necessarily represent bearish bets.

Bitcoin moved above $82,000 on May 6, 2026, briefly reaching about $82,600 and gaining 2% over 24 hours, according to CoinGecko. K33 Research said the 30-day average funding rate for perpetual futures had remained negative for 66 consecutive days, the longest stretch this decade. Open interest rose about 12% over the same period, while U.S. spot Bitcoin ETFs recorded $2.44 billion in net inflows in April, underscoring how spot buying and futures hedging are occurring in tandem.
