Coinbase Premium Turns Positive as Bitcoin Tests $81,000
The Coinbase Premium turned positive on 28 August for the first time since May, indicating that Bitcoin demand among US-based buyers has strengthened relative to Binance and overseas markets. The shift coincided with Bitcoin’s advance towards $80,000 and renewed buying through spot Bitcoin ETFs.
Data from SoSoValue showed that major Bitcoin ETFs, led by BlackRock’s IBIT, attracted $3.51 billion in recent inflows, the highest level since October 2025. Several of these funds use Coinbase as their asset custodian, linking the ETF demand to activity on the exchange.
The Coinbase Premium is closely watched because sustained positive readings can signal stronger institutional and regulated US demand. Analysts said Bitcoin must break above its 50-week simple moving average near $81,000 to confirm a potential shift from a bear market to a new bullish phase. Traders will therefore monitor whether the premium remains positive and whether ETF inflows continue.
Bullish
The news is bullish because the Coinbase Premium has turned positive, suggesting that US demand is outpacing demand on overseas exchanges. The signal is reinforced by $3.51 billion in recent Bitcoin ETF inflows, which may reflect renewed institutional buying and provide additional spot-market support.
In the short term, a sustained positive Coinbase Premium could encourage traders to test resistance around $80,000-$81,000. A break above Bitcoin’s 50-week simple moving average near $81,000 could trigger momentum buying, short covering and increased confidence that the broader downtrend is ending. Continued ETF inflows would strengthen this scenario.
However, the signal is not conclusive. Coinbase Premium readings can change quickly if US demand weakens, while the $81,000 level remains a significant technical barrier. Failure to break and hold above that area could lead to profit-taking or a pullback, particularly if ETF inflows slow. Historically, positive Coinbase Premium periods have often accompanied stronger Bitcoin rallies, but traders should confirm the move with sustained volume, ETF flows and price acceptance above resistance. Over the longer term, persistent institutional inflows would be more constructive for market stability and Bitcoin’s trend than a brief premium spike.
