US Spot Bitcoin ETFs Record $3 Billion Inflow Streak

US spot Bitcoin ETFs have recorded a nine-day winning streak, attracting approximately $3 billion in capital since September 17. This period of institutional buying has shifted year-to-date flows from a negative position to a net positive of roughly $934 million.

The week ending September 25 saw the strongest performance, with $2.4 billion in net inflows. This represents the largest weekly haul since October 2025. September 21 was the most active day of the streak, recording nearly $999 million in inflows.

BlackRock’s iShares Bitcoin Trust led the market with approximately $1.2 billion in inflows during that week. Fidelity’s FBTC followed with about $702 million, while ARK 21Shares’ ARKB added roughly $295 million. These three products combined for over 90% of the total capital inflows.

The recent activity marks a significant reversal from earlier in the year, when cumulative net flows had dropped to negative $5.8 billion by July. During the recent inflow streak, Bitcoin’s price stabilized between $83,000 and $87,000.

Since their inception in January 2024, US spot Bitcoin ETFs have reached over $57 billion in cumulative net inflows. By late September, total assets under management for the category neared $108 billion.

The dominance of IBIT and FBTC suggests interest from large, risk-conscious allocators, while the inclusion of ARKB indicates continued demand from growth-oriented investors. This buying activity follows a period where Bitcoin had fallen roughly 34% from its October 2025 peak of approximately $126,000.

While daily inflows showed some tapering after the September 21 peak, the positive streak continued through at least September 29.
