Bitcoin Open Interest Rises Above 2025 Peak as 2026 Derivatives Activity Accelerates
Bitcoin open interest is climbing sharply in 2026, with derivatives positioning now exceeding the peak levels seen during the 2025 all-time-high phase. The build-up across futures and perpetual markets suggests heavier participation and faster-growing leverage, conditions that can precede larger price swings. Traders are watching whether BTC can hold key support after a breakout, as downside targets cited include $82,800 and the $75,000–$76,000 zone.
