U.S. Spot Bitcoin ETFs End Nine-Day Inflow Streak With $148.7 Million Outflow

U.S. spot Bitcoin ETFs record $148.7 million in net outflows, ending a nine-day, $3.1 billion inflow streak led by Fidelity FBTC.

U.S. spot Bitcoin exchange-traded funds recorded $148.7 million in net outflows on Wednesday, ending a nine-day run that had brought approximately $3.1 billion into the funds, according to data shared by Coin Bureau on X.

The reversal marked the first net outflow after nine consecutive sessions of positive flows. Fidelity's FBTC accounted for the largest withdrawal at $125.6 million, while BlackRock's IBIT recorded $9.5 million in outflows. Bitwise's BITB also posted a $13.6 million withdrawal, according to Farside Investors data.

Fidelity Leads Wednesday's Withdrawals

Fidelity's FBTC was responsible for most of Wednesday's redemptions, with $125.6 million leaving the fund. BlackRock's IBIT followed with $9.5 million, bringing its own nine-session inflow streak to an end. Bitwise's BITB recorded the remaining $13.6 million among the funds that posted net outflows.

The other U.S. spot Bitcoin ETFs recorded no net flows during the session, according to the same data. The distribution of withdrawals meant the overall $148.7 million decline was concentrated in three products rather than spread broadly across the ETF market.

IBIT's reversal came after a particularly strong stretch for the fund. BlackRock's ETF had recorded nine consecutive sessions of inflows before Wednesday's $9.5 million outflow, according to reporting based on ETF flow data.

September Run Pushes 2026 Flows Back Into Positive Territory

The latest outflow followed a sustained period of buying that helped reverse earlier weakness in U.S. spot Bitcoin ETF flows.

The nine-session run from September 17 through September 29 generated approximately $3.1 billion in combined net inflows. The final positive session before the reversal brought $66.2 million into the products on September 29, with IBIT attracting $51.1 million and ARKB receiving $33.2 million, partially offset by an $18.1 million outflow from BITB.

Despite Wednesday's reversal, cumulative ETF flows for 2026 remained positive after the recent run. The broader U.S. spot Bitcoin ETF market has accumulated about $57.5 billion in net inflows since trading began in January 2024, while total assets across the funds stood at roughly $108 billion as of September 30.

One-Day Reversal Follows Stronger Institutional Demand

Coin Bureau characterized the September 30 outflow as a sharp cooling in institutional demand following one of the strongest ETF inflow periods of the year. The data itself, however, shows that the withdrawal represented a single negative session after nine consecutive positive sessions.

The scale of the preceding inflows also remains visible in the monthly figures. September's ETF activity included a particularly strong five-day stretch from September 21 through September 25, when the funds recorded roughly $2.39 billion in net inflows.

For now, the next trading sessions will show whether Wednesday's withdrawals represent a short-term reversal or the beginning of a longer change in the flow pattern. The immediate benchmark is whether U.S. spot Bitcoin ETFs resume net inflows after the markets September 30 outflow.
