Coinbase Bitcoin Premium Stays Negative for 75 Days, Setting Record as Prior Rebound Was Followed by a 20% BTC Gain

CoinGlass data shows the Coinbase Bitcoin Premium Index has stayed below zero for 75 straight days since May 19, with the latest reading at -0.0959%, the longest negative streak on record for the metric. A negative reading means Bitcoin is priced lower on Coinbase than on Binance, a pattern often read as weaker U.S. spot demand. The previous record lasted 40 days, from Jan. 16 to Feb. 24. After that stretch ended, Bitcoin rose from $64,080 to $76,954 over the next three months, a gain of 20%. The report also lines up the premium data with U.S. spot Bitcoin ETF flows. Those ETFs posted net outflows of $2.43 billion in May and $4.51 billion in June, followed by a much smaller net inflow of $205 million in July. Total net assets stood at $77.46 billion on July 29, down from roughly $151 billion at a peak in September 2025. The article adds that the Coinbase premium index only captures pricing in public order books, not OTC trades or institutional channels such as Coinbase Prime, so it cannot by itself prove institutions are selling Bitcoin.
