Bitcoin has rallied back above $86,000, an eight-month high.

Bitcoin ($BTC) surged past $86,000 on Monday, marking its highest price level since January 2026 and lifting total market capitalization to $1.72 trillion as an aggressive spot and perpetual futures squeeze triggered widespread short liquidations across crypto derivatives markets.
Key market metrics and structural drivers include:
• Derivative Liquidations: The rapid advance from $75,000 on September 15 triggered $929.1 million in total crypto liquidations over 24 hours, with short liquidations exceeding $648 million and forcing over 131,000 leveraged traders to close positions.
• U.S. Spot ETF Profitability: The rebound above $86,000 pushed average U.S. spot Bitcoin ETF holders back into net unrealized profit for the first time since January, clearing the estimated aggregate purchase cost basis near $81,720 and trimming Bitcoin's year-to-date drawdown below 2%.
• Supply Dynamics & Open Interest: On-chain data indicates supply concentration among larger institutional entities following summer distribution by smaller retail cohorts (0.1–10 BTC), while aggregate futures open interest expanded over 11.5% to $61.2 billion.
• Technical Resistance: Momentum faces immediate overhead resistance between $87,500 and the psychological $90,000 threshold, with prior consolidation support established near $82,200.
