Binance’s open interest (outstanding futures positions) surged nearly 8% in 24 hours to above $10 billion, its highest level in six months, as Bitcoin retested the May high near $82,000. Open interest measured in Bitcoin reached 125,830 BTC, and the increase remained genuine after excluding price effects. Binance’s market share exceeded 37%. CryptoQuant analyst Darkfost said futures-market speculation can create demand and push Bitcoin higher, but such moves are often brief. A sustained bullish trend would require participation from spot investors, a condition that is not yet present.
