Analysis: Cryptocurrency market makers profit from basis trading during the Bitcoin rebound, rather than betting on direction

According to CoinDesk, as Bitcoin surged from about $62,000 to over $77,000 last week, liquidating approximately $3 billion in leveraged short positions, major crypto market makers such as Abraxas Capital, Fasanara Capital, and Wintermute quietly established short positions in perpetual contracts worth hundreds of millions of dollars on Hyperliquid.

Lookonchain data shows that the three institutions collectively hold short positions of 138,569 ETH (approximately $338 million) and 3,425 BTC (approximately $265 million); meanwhile, Abraxas Capital withdrew 73,872 ETH (approximately $173 million) from Binance in the past four days.

This strategy is known as cash arbitrage or basis trading: traders hold spot positions while shorting an equivalent amount of assets through perpetual contracts to hedge against price volatility risks, primarily earning the funding rates paid by longs to shorts. In previous months, funding rates were long suppressed or even turned negative, but this month's rebound has quickly turned funding rates positive, reopening the arbitrage window. Aegis data shows that the 30-day average funding rate for Bitcoin perpetual contracts on August 24 reached an annualized 6.7%, with a 7-day average of 8.7%; 21shares capital markets noted that basis trading for mainstream assets like Solana is also becoming lucrative.

This trading has extended to regulated markets: Glassnode data shows that CME Bitcoin futures open interest has risen from about 87,000 BTC to 122,000 BTC.
