US spot Bitcoin ETFs recorded their strongest weekly performance in nearly a year, attracting $2.4 billion in net inflows for the week ending September 25, 2026. This surge pushed year-to-date net flows into positive territory at approximately $934 million, marking a recovery from a $5.8 billion deficit observed in mid-July.
BlackRock’s iShares Bitcoin Trust led the market with $1.2 billion in inflows, followed by Fidelity’s FBTC with $702 million and ARK 21Shares’ ARKB with $295 million. Together, these three funds captured over 90% of the week's total capital. Daily inflows peaked at nearly $999 million on Monday before slowing to $135 million by Friday.
The market activity coincided with Bitcoin price fluctuations, as the asset reached $87,000 early in the week before retreating to a range between $83,000 and $84,000. Beyond Bitcoin, other crypto products saw significant interest: Ether ETFs attracted $690 million, Solana ETFs drew $188 million, and XRP ETFs added $76 million.
Since their launch in January 2024, spot Bitcoin ETFs have accumulated over $57 billion in net inflows. By late September 2026, total assets under management reached approximately $108 billion. This follows a volatile period earlier in the year, which included a record monthly outflow of $4.51 billion recorded in June 2026.
