Coinbase premium gap hits a yearly low as CryptoQuant flags institutional selling

Bitcoin’s latest slide is showing up in an unusual place: the US venue that often leads institutional price discovery.

CryptoQuant data shows the Coinbase Premium Gap, a measure that compares the Bitcoin price on Coinbase and Binance, has dropped to its weakest reading in roughly a year, adding fresh context to the ongoing comparisons of Binance vs Coinbase. The gauge tracks the spread between Coinbase’s BTC/USD market and Binance’s BTC/USDT market. When the spread turns sharply negative, it means Bitcoin is trading cheaper on Coinbase than on Binance, a pattern typically linked with heavier selling from US-based participants.

CryptoQuant analyst Darkfost said the premium has “never been this negative since the beginning of the year,” adding that the selling pressure is intensifying on the institutional side. The analyst pointed to Coinbase Advanced Trade as a venue widely used by professional and high-net-worth accounts, making the discount notable when it persists. 

On the data side, CryptoQuant put the Coinbase Premium Gap at about -167.8, its lowest level since December 2024. The firm described the downtrend as a sign that large holders have been selling into weaker bids and that activity on Coinbase has cooled since the mid-October pullback, with the decline accelerating over the past week. 

The premium story lines up with a broader shift in institutional flows. In a separate market note, CryptoQuant said institutional demand has “reversed materially” this year. The firm pointed to US spot Bitcoin ETFs, which had bought more than 46,000 BTC around this time last year, but have instead become net sellers in 2026, offloading about 10,600 BTC. That swing implies a roughly 56,000 BTC demand gap versus 2025 and adds to persistent sell pressure.

Recent fund flow totals have reinforced the message. Spot Bitcoin ETFs have logged roughly $1.2 billion in net outflows over the past week, while Bitcoin dropped below $71,000 at one point during the selloff.

For traders, the next tell is whether the Coinbase premium stabilizes and flips back to neutral. If the gap stays deeply negative, it signals that the largest buyers are still leaning on the bid, and rallies can struggle to hold.
