According to Odaily, K33 senior analyst Vetle Lunde reported on the X platform that the open interest (OI) for Bitcoin futures on the Chicago Mercantile Exchange (CME) reached a record high of 172,430 BTC yesterday, setting a new historical peak. The current institutional preference indicates an increase in long positions. The surge in open interest has also driven the futures premium to a five-month high, primarily fueled by active market participants rather than inflows into futures-based ETFs. Over the past three days, open interest has increased by 19,120 BTC, marking the largest three-day growth since June 2023, with market activity concentrated on contracts expiring in November.
