Key Takeaways

- • BlackRock's IBIT saw $9.5 million exit after accumulating $1.6 billion over nine days, while Fidelity's FBTC led outflows with $125.6 million, signaling potential profit-taking or rebalancing activity across the largest Bitcoin ETF managers.

Summary
The nine-day inflow streak for U.S. spot Bitcoin exchange-traded funds, which had channeled $3.1 billion into the product category, concluded on October 1, 2026, as managers recorded $148.7 million in net outflows. The reversal ended one of 2026's most significant positive periods for Bitcoin ETFs, though the prior winning streak had successfully moved cumulative year-to-date flows back into positive territory following months of sustained withdrawals.
BlackRock's IBIT, the category's dominant fund by assets, experienced $9.5 million in outflows after capturing $1.6 billion during the nine-day run. Fidelity's FBTC accounted for the largest single outflow with $125.6 million exiting the fund, while Bitwise's BITB saw $13.6 million depart. Other Bitcoin ETF products registered zero flows, concentrating the exit activity among the largest fund managers.
The nine-day streak represents a significant but incomplete recovery from the year's earlier weakness. Bitcoin ETFs remain approximately $5 billion below their cumulative flow peak recorded on October 10, 2025, according to Bloomberg ETF analyst James Seyffart. Nevertheless, the recovery underscores underlying institutional appetite: the product category has accumulated over $57 billion in cumulative net inflows since its January 2024 launch and now manages over $100 billion in assets. Bloomberg Senior ETF Analyst Eric Balchunas characterized the recovery as "arguably astonishing given what they've been through over the past 11 months," highlighting the resilience of institutional investor demand despite volatility.
Morgan Stanley's MSBT fund, the newest Bitcoin ETF entrant launched in April 2026, topped 10,000 BTC in assets under management for the first time last week, suggesting broader industry participation in the product space. Meanwhile, U.S. spot Ethereum ETFs diverged from Bitcoin's trajectory, extending their outflow streak to two consecutive days with $59.6 million in net withdrawals led by $26.6 million exiting Fidelity's FETH fund. Ethereum ETFs, which launched in July 2024, have accumulated approximately $14 billion in total net inflows since inception, reflecting weaker institutional demand compared to Bitcoin's dominance.
