Bitcoin ETFs See $3 Billion in Inflows
US spot Bitcoin ETFs witnessed $3 billion in net inflows between September 17 and September 25, 2026. This surge pushed the year's flow tally out of the red. The largest single day inflow was $999 million, occurring on September 21, 2026. The inflows were led by BlackRock's IBIT with $1.2 billion, Fidelity's FBTC with $702 million, and ARK 21Shares' ARKB with $295 million. The third quarter of 2026 recorded $6.34 billion in Bitcoin ETF inflows, the highest of any quarter this year. By early October 2026, cumulative net inflows reached approximately $57-58 billion, with total assets under management around $105-110 billion. The inflows coincided with Bitcoin's price recovery, trading between $82,000 and $87,000. The concentration in BlackRock's IBIT also stood out, with around $1.2 billion of the peak-week inflows. However, net outflows resumed in early October 2026, including a $244 million outflow on October 8. The late-September data suggests that institutions still see Bitcoin as a legitimate portfolio holding, not just a speculative side bet.
