US spot Bitcoin exchange-traded funds experienced their initial daily outflow in over two weeks, halting a momentum-building recovery that had driven total cumulative flows near historic levels.
Data from Farside Investors shows the funds suffered $148.7 million in net withdrawals on Sept. 30, bringing an end to a nine-session winning streak that had accumulated roughly $3.08 billion.
The downturn was primarily led by Fidelity’s FBTC, which saw $125.6 million leave the fund. Additional losses came from Bitwise’s BITB at $13.6 million and BlackRock’s IBIT at $9.5 million, with the remaining nine funds reporting flat flows.
Even with this interruption, September finished with robust gains. The investment vehicles pulled in approximately $2.65 billion over the course of the month, marking the second-highest monthly total for the year trailing only August’s $3.52 billion.
Furthermore, September’s positive inflows lifted net inflows for 2026 to about $930 million following an extended period earlier in the year spent in negative territory.
This resurgence has similarly propelled lifetime cumulative flows back toward their prior peak. Figures from Bloomberg Intelligence indicate that cumulative inflows hit a high of roughly $62.8 billion on Oct. 10, 2025, prior to a protracted sequence of redemptions that wiped out a significant portion of those gains.
By July 13, the cumulative decline from that peak stretched to approximately $12 billion, dragging lifetime figures down to about $50.9 billion. Renewed interest since then has substantially trimmed that shortfall, lifting cumulative flows to near $57.7 billion by late September.
Consequently, the products sit roughly $5 billion shy of matching their former peak.
Bitcoin ETF recovery faces its first interruption
According to Bloomberg ETF analyst Eric Balchunas, the rebound is particularly remarkable considering the intense pressure Bitcoin ETFs faced throughout the preceding 11 months.
He noted that capital inflows have bounced back to rates characteristic of their past vigor, even while Bitcoin battles elevated yields and lingering pessimistic sentiment. This comeback, he continued, has complicated the bearish narrative as prices steadily climb.
As a result, the Sept. 30 outflow alone does not provide a definitive answer on whether the recovery has stalled. The withdrawal was heavily anchored in Fidelity’s product, whereas the majority of the fund complex saw zero activity.
Consequently, upcoming trading sessions carry heightened importance. Widespread redemptions spanning BlackRock, Fidelity, and other major providers would indicate that the recent upward trend is fading. Conversely, a return to net inflows would reframe Tuesday’s dip as merely a brief respite following a buying wave exceeding $3 billion.
With Bitcoin changing hands near $83,800 on the morning of Oct. 1, ETF demand remains a premier indicator for tracking whether institutional investors are actively increasing their exposure at these price points.
The immediate objective is clear: the funds require approximately $5 billion more in cumulative inflows to completely recover from last October’s peak drawdown. Whether they manage to bridge that remaining gap hinges on how swiftly purchasers step back in following the final session of September.
