US spot Bitcoin exchange-traded funds (ETFs) recorded their first daily outflow in more than two weeks, interrupting a recovery that had pushed cumulative flows close to a record.
The funds posted $148.7 million of net withdrawals on Sept. 30, ending nine consecutive positive sessions that brought in about $3.08 billion, according to Farside Investors.
Fidelity’s FBTC drove most of the reversal, with $125.6 million in outflows. Bitwise’s BITB lost $13.6 million, and BlackRock’s IBIT shed $9.5 million, while the other nine listed funds recorded no net flows.
Despite the setback, September remained strongly positive. The products attracted about $2.65 billion during the month, their strongest monthly flow this year behind August’s $3.52 billion.
Meanwhile, the positive September flow brought 2026 net inflows to roughly $930 million after much of the year was spent underwater.
The recovery has also brought lifetime cumulative flows back toward their previous high. Bloomberg Intelligence data show the products peaked at about $62.8 billion in cumulative inflows on Oct. 10, 2025, before months of redemptions erased much of that progress.
By July 13, the cumulative drawdown from that peak had reached about $12 billion, leaving lifetime flows near $50.9 billion. Fresh demand since then has narrowed the deficit considerably, with cumulative flows recovering to around $57.7 billion by late September.
That leaves the products roughly $5 billion short of their previous high-water mark.
Bitcoin ETF recovery faces its first interruption
Bloomberg ETF analyst Eric Balchunas said the rebound was notable given the pressure Bitcoin ETFs had endured over the previous 11 months.
He said flows had returned to levels reminiscent of their earlier strength even as Bitcoin contended with higher yields and lingering negative sentiment. The recovery, he added, had made the bearish case harder to sustain as price continued grinding higher.
This suggests the Sept. 30 outflow does little on its own to settle whether the rebound has run its course. The withdrawal was heavily concentrated in Fidelity’s fund, while most of the complex registered no movement.
That makes the next sessions more consequential. A broader run of redemptions across BlackRock, Fidelity and other large issuers would suggest the recent recovery is losing momentum. However, renewed inflows would leave Tuesday’s move looking more like a pause after more than $3 billion of buying.
Bitcoin traded around $83,800 early Oct. 1, leaving ETF demand as one of the clearest gauges of whether institutional buyers continue adding exposure near current levels.
The next milestone is straightforward: the funds need roughly another $5 billion of cumulative inflows to erase the drawdown from last October’s peak. Whether they continue closing that gap will depend on how quickly buyers return after September’s final-session reversal.
