U.S. spot Bitcoin ETFs closed September in the red, ending a 9-day, $3.1 billion inflow streak.
The funds recorded $148.7 million in net outflows on Wednesday.
Fidelity's $FBTC led the exits with $125.6 million, while BlackRock's $IBIT saw $9.5 million leave the fund, ending its own nine-day inflow streak.
Despite the reversal, the recent run was strong enough to push 2026 cumulative ETF flows back into positive territory.
One red day does not erase the trend, but it does show institutional demand cooled sharply after one of the strongest ETF runs of the year.
