Key Takeaways
  • • Bitcoin futures open interest across 22 exchanges rose 4.3%, from 619,645 BTC on Oct. 12 to 646,442 BTC on Oct. 15, as the price fell to $79,821.
  • • Crypto futures liquidations reached $1.18 billion in the 24 hours through Oct. 8, including $1.05 billion in long positions, and $948 million in the 24-hour window leading to Oct. 15; these totals cover crypto futures broadly, not Bitcoin alone.
  • • U.S. spot Bitcoin ETFs recorded $228.4 million in net outflows over Oct. 12–16, 66.4% less than the $678.9 million withdrawn the prior week.
  • • Bitcoin closed above $81,300 every day from Oct. 15 through Oct. 18 despite intraday dips, and an estimated 646,000 BTC had cost bases between $80,353 and $82,224 as of Oct. 18.
  • • A daily close below $79,821, combined with renewed long liquidations and elevated open interest, would strengthen the case for another forced unwind; a brief dip alone would not confirm one.
Summary
Bitcoin futures open interest rose during a price decline, keeping liquidation risk in focus for leveraged traders. According to data cited in the report, open interest across 22 exchanges climbed from 619,645 BTC on Oct. 12 to 646,442 BTC on Oct. 15, a 4.3% gain, as Bitcoin fell to $79,821 on Oct. 15. The report notes that open interest counts active contracts but does not reveal whether traders are predominantly long or short.

Short exposure grew during the decline. As Bitcoin recovered toward $83,000, leveraged longs returned and funding rates turned positive. Such shifts in positioning matter because a falling price can force leveraged long positions to close, amplifying downside moves.

Liquidation data underscores the stress in derivatives markets. Crypto futures liquidations totaled $1.18 billion in the 24 hours through Oct. 8, including $1.05 billion in long positions, while a separate 24-hour window leading to Oct. 15 recorded $948 million. The report stresses that these figures cover crypto futures broadly rather than Bitcoin alone.

Spot demand has been mixed. U.S. spot Bitcoin ETFs recorded $228.4 million in net outflows across Oct. 12–16, which was 66.4% lower than the $678.9 million withdrawn during Oct. 5–9. Inflows on two days did not offset outflows on the other three.

Price action has held above key levels so far. Bitcoin traded below $81,300 on each day from Oct. 15 through Oct. 18, with daily lows of $79,821, $80,817, $80,820 and $80,700, yet closed above $81,300 every day, so no daily close below that threshold occurred. An estimated 646,000 BTC had cost bases between $80,353 and $82,224 as of Oct. 18, up 366,000 BTC from Oct. 11, placing substantial supply near recent lows. The estimate does not establish when individual purchases occurred.

The report concludes that a brief move under $79,821 alone would not confirm another forced unwind. A daily close below that level, together with renewed long liquidations and elevated open interest, would strengthen that case.
