Bitcoin ETFs See $463M Outflows; Ether Funds Add $197M

US spot Bitcoin exchange-traded funds recorded $462.7 million in net outflows last week, reversing a three-week inflow run, according to Farside Investors. The withdrawals occurred across four trading sessions from Tuesday to Friday of a holiday-shortened week.

The funds lost $166.8 million in the first two days, and selling intensified later in the week. Thursday saw the largest single-day withdrawal, with Bitcoin ETFs posting $282.7 million in net outflows, the biggest daily outflow since July. Friday’s outflow slowed to $13.2 million, extending the negative streak to four consecutive trading days, based on data compiled by SoSoValue.

At the fund level, ARK 21Shares Bitcoin ETF led weekly redemptions with $234.2 million in net outflows. Grayscale’s Bitcoin Trust posted $129.1 million in net redemptions, BlackRock’s iShares Bitcoin Trust recorded $52.5 million in outflows, and Fidelity’s Wise Origin Bitcoin Fund had $50.7 million in net outflows for the week. Despite the weekly reversal, spot Bitcoin ETFs remained positive for September with about $307.3 million in net inflows through Friday.

US spot Ether ETFs moved in the opposite direction over the same four trading days, drawing $196.9 million in net inflows, according to Farside Investors. The Ether category showed mixed flows earlier in the week: $24.3 million in outflows on Tuesday, $34.7 million in inflows on Wednesday and $29.9 million in outflows on Thursday. A strong Friday added $216.4 million to the category.

Friday’s inflows were concentrated in a few funds. BlackRock’s iShares Ethereum Trust accounted for $148.8 million of the day’s inflows, while 21Shares Core Ethereum ETF added $29.1 million. The weekly figures were tracked by market-data providers Farside Investors and SoSoValue and reflect short-term reallocations between US-listed spot crypto exchange-traded products.
