Woofun AI data shows that the Coinbase Bitcoin premium index has maintained negative territory for 49 consecutive days as of May 19, establishing a new record for the longest such streak. The latest value stands at -0.1072%, exceeding the previous 40-day negative period recorded between January 16 and February 24. Historical patterns indicate that extended negative premiums frequently coincide with institutional capital outflows from the U.S., potentially signaling short-term correction risks.
