Woofun AI data shows that the Coinbase Bitcoin premium index has remained in negative territory for 55 consecutive days, extending from May 19 to the present with a latest value of -0.0072%. This duration surpasses the previous record of 40 consecutive days observed between January 16 and February 24, as well as the roughly 30-day negative period during the "1011 crash".

Historical patterns indicate that extended negative premiums often coincide with institutional capital exiting the U.S. market, suggesting caution regarding potential short-term downward pressure.
