US spot bitcoin exchange-traded funds saw a sharp surge in activity on September 3, with net inflows of $730.8 million in a single trading session. That’s the largest daily figure in nearly eight months — bigger volumes were only recorded in mid-January 2026, when the daily figure exceeded $844 million. The buying spree coincided with the cryptocurrency’s attempt to hold above the $80,000 level.
BlackRock Dominates as Sentiment Shifts
As usual, the iShares Bitcoin Trust (IBIT), managed by investment giant BlackRock, absorbed the lion’s share of liquidity. Investors poured about $454 million into it, accounting for over 60% of the day’s total volume.
According to data from analytics service Farside Investors, most major players saw positive flows:
- ARK 21Shares received $137.7 million;
- Fidelity Wise Origin added $74.4 million;
- Bitwise BITB attracted $24.8 million, while the Grayscale fund family collectively saw net inflows of $57 million;
- Only VanEck and WisdomTree products bucked the trend, posting net outflows of $19.6 million and $5.2 million, respectively.
The result stands in stark contrast to the turbulent start of September. Just on September 1, the funds ended the day with massive outflows of $236.5 million, but over the next 48 hours, daily inflows grew more than sevenfold. The total net inflows into US spot ETFs since their approval have approached $55.5 billion.
Fed Rate Expectations and Analyst Caution
The surge in institutional interest unfolded alongside the asset’s price action. Amid the inflows, bitcoin briefly rose above $80,000 before stabilizing in a range between $76,000 and $81,000.
As industry publication The Block reports, demand for crypto assets was supported by expectations of looser US monetary policy following fresh rhetoric from Federal Reserve officials. Still, analysts caution against excessive optimism: a single day of record buying often signals a targeted rebalancing of fund portfolios at a price bottom rather than the guaranteed start of a new bull cycle.
