Bitcoin ETFs shed $463M in weekly reversal as Ether ETFs gain $197M

US spot Bitcoin exchange-traded funds experienced $462.7 million of net withdrawals last week, reversing three straight weeks of inflows, according to flow data compiled by Farside Investors. The redemptions were spread across four trading days from Tuesday through Friday, with the heaviest selling occurring on Thursday when the funds registered a $282.7 million outflow — the largest daily withdrawal since July. Sales eased on Friday but the negative streak reached four consecutive trading sessions, per SoSoValue.

ARK 21Shares Bitcoin ETF (ARKB) led the weekly exits, recording $234.2 million in net outflows, followed by Grayscales Bitcoin Trust (GBTC) at $129.1 million. BlackRocks iShares Bitcoin Trust (IBIT) saw $52.5 million leave, and Fidelitys Wise Origin Bitcoin Fund shed $50.7 million. Despite the pullback over the week, spot Bitcoin ETFs remained positive for September overall, with roughly $307.3 million in net inflows through Friday.

By contrast, US spot Ether ETFs drew $196.9 million in net inflows across the same four-day span. The Ether funds experienced mixed activity earlier in the week — $24.3 million outflow on Tuesday, a $34.7 million inflow on Wednesday, and $29.9 million outflow on Thursday — before a strong Friday that added $216.4 million and turned the week positive, per Farside Investors.

BlackRocks iShares Ethereum Trust (ETHA) accounted for the lions share of Fridays inflows, contributing $148.8 million, while 21Shares Core Ethereum ETF added $29.1 million. The concentration of flows into a few large Ether products highlights how single funds can swing weekly totals, and underscores the current rotation in investor demand between Bitcoin and Ether ETFs.
