Spot Bitcoin ETFs Record $2.4B Weekly Inflow as Year-to-Date Flows Turn Positive
US spot Bitcoin ETFs saw their strongest weekly performance since October 2025, pulling in $2.4 billion and pushing year-to-date net flows into positive territory.

US spot Bitcoin ETFs experienced a significant surge in institutional interest, recording $2.4 billion in net inflows for the week ending September 25. This performance marks the largest weekly inflow for the sector since early October 2025.
The influx of capital successfully reversed a negative year-to-date trend. Net flows for the category now stand at approximately $934 million, a notable recovery from the $5.8 billion deficit recorded in mid-July.
BlackRock’s iShares Bitcoin Trust led the market with $1.2 billion in inflows. Fidelity’s FBTC followed with $702 million, while ARK 21Shares’ ARKB attracted $295 million. Together, these three products captured over 90% of the week’s total capital.
Daily momentum peaked on Monday with nearly $999 million in inflows before slowing toward the end of the week. Friday’s total dropped to $135 million as Bitcoin’s price retreated from a high of $87,000 to a range between $83,000 and $84,000.
The broader market also saw increased activity across other crypto-linked products. Ether ETFs brought in $690 million, Solana ETFs added $188 million, and XRP ETFs recorded $76 million in inflows.
The recent seven-session inflow streak indicates a shift in market positioning following a difficult first half of 2026, which included $4.51 billion in outflows during June. Since their launch in January 2024, spot Bitcoin ETFs have reached over $57 billion in cumulative net inflows, with total assets under management hitting approximately $108 billion by late September 2026.
