US spot Bitcoin exchange-traded funds recorded $462.7 million in net outflows across the four trading sessions ending Friday, erasing the momentum of the strongest three-week inflow streak of 2026. At the same time, spot Ether ETFs collected $196.9 million over the identical period, a turnaround driven by a single heavy session on Friday.
The Bitcoin reversal
The withdrawal wave began Tuesday and accelerated through Thursday, when the funds shed $282.7 million, the largest single-day redemption since July, according to SoSoValue. Friday’s $13.2 million outflow was modest by comparison but extended the losing streak to four consecutive sessions. The holiday-shortened week had already opened with $166.8 million in redemptions across its first two days, Farside Investors data shows.
Where the selling concentrated
ARK 21Shares Bitcoin ETF accounted for $234.2 million of the weekly total, more than half the outflow. Grayscale’s Bitcoin Trust ETF followed with $129.1 million. BlackRock’s iShares Bitcoin Trust ETF and Fidelity’s Wise Origin Bitcoin Fund each lost roughly $50 million. The breadth suggests the move was not confined to a single issuer’s investor base.
September still positive
Despite the weekly reversal, the Bitcoin ETF complex remains in positive territory for the month. Through Friday, net inflows since the start of September stand at approximately $307.3 million, meaning the recent selling has only partially unwound earlier gains.
Ether ETFs find footing
Ether funds followed a choppier path. Tuesday brought $24.3 million in outflows, Wednesday added $34.7 million in inflows, and Thursday saw another $29.9 million exit. Friday changed the picture: $216.4 million flowed in, led by BlackRock’s iShares Ethereum Trust ETF with $148.8 million and 21Shares Core Ethereum ETF with $29.1 million. The weekly total of $196.9 million marks the first positive four-day stretch for the Ether suite in several weeks.
