The Coinbase Bitcoin Premium Index has stayed negative for a record 90 straight days, according to unconfirmed CoinGlass data, a persistent stretch that suggests Bitcoin has been trading at a relative discount on Coinbase compared with other major exchanges.
The Coinbase Bitcoin Premium Index has stayed negative for a record 90 straight days, according to unconfirmed CoinGlass data, a persistent stretch that suggests Bitcoin has been trading at a relative discount on Coinbase compared with other major exchanges.
The Coinbase Bitcoin Premium Index tracks the gap between Bitcoin’s price on Coinbase and its price on other large exchanges. A positive reading means Coinbase trades at a premium; a negative reading means it trades at a discount. For related coverage, see Bitcoin Falls Below $69,000, Down 1.27% on the Day.
Because Coinbase is the primary on-ramp for many US-based investors, the metric is often read as a rough proxy for US-led spot demand. A sustained discount on Coinbase points to softer buying pressure from that cohort relative to activity elsewhere.

The same indicator is charted independently by CryptoQuant, which publishes its own Coinbase Premium Index based on the price spread between Coinbase Pro and Binance.
The notable development is duration, not depth. According to unconfirmed reports drawn from CoinGlass, the index has now printed negative readings for 90 consecutive days, described as a record run for the metric.
A single negative print is routine and reflects normal spread noise between venues. A streak stretching across three months is different because it signals a persistent, rather than fleeting, discount on the exchange most associated with US retail and institutional flows.
This is not the first time the gauge has drawn attention. Earlier readings showed the Coinbase premium weakening under market pressure, and a prolonged stretch below zero has previously coincided with reports of US investors leaning toward selling on the platform.
Traders typically interpret Coinbase-relative weakness as a sign that US buyers are less aggressive than offshore participants. A 90-day discount, if confirmed, would be consistent with muted domestic spot appetite over that window.
That interpretation should stay measured. The premium index is one narrow spread indicator, and it should not be treated as a standalone verdict on Bitcoin’s direction, especially given that the underlying streak figure here is not independently verified.
The signal worth monitoring is a shift back above zero. A move from a sustained discount into positive territory on the premium gauge would mark the clearest change in tone, hinting that US-based demand is re-engaging after the prolonged negative run. Historically, a firming premium has been read alongside other Coinbase-based signals used to gauge bullish momentum.
Until then, the data supports only a cautious read: a long-running, unusual discount on Coinbase that reflects the balance of spot activity across venues, without confirming any particular price outcome.
