Bitcoin Open Interest Records Biggest Surge of 2026

Bitcoin open interest has posted its strongest increase of 2026, surpassing levels seen during Bitcoin’s previous all-time high formation. The surge signals renewed trader activity in futures markets, despite funding rates remaining broadly negative in recent weeks. Binance continues to dominate derivatives trading with roughly 34% market share and $2.5 billion in average monthly open interest, followed by Gate.io and Bybit. Analysts say the trend reflects returning market optimism, though rising leverage also increases liquidation risks and potential volatility.
