U.S. spot Bitcoin ETF suffered a four-day net outflow, and Ether ETF bucked the trend to attract gold.
Last week, U.S. spot Bitcoin exchange-traded funds (ETFs) experienced a significant reversal, recording a net redemption of US$462.7 million in four trading days. The reversal ended three consecutive weeks of net inflows and marked the most drastic withdrawal period the funds have experienced since July.
Bitcoin ETF faces four consecutive days of outflows
According to Farside Investors, redemption of spot Bitcoin ETF continues every trading day from Tuesday to Friday. Although the week benefited from the strongest three-week influx of funds in 2026 at the beginning of the week, the momentum quickly dissipated as an outflow of $166.8 million was recorded in the first two trading days of the shortened holiday week.
According to SoSoValue, the largest one-day outflow occurred on Thursday, when investors withdrew $282.7 million from the U.S. spot Bitcoin ETF, setting the largest one-day redemption since July. Outflows eased on Friday to $13.2 million, but still extended the streak of losses to four consecutive days.
In four trading days, the U.S. spot Bitcoin ETF has accumulated net redemptions of US$462.7 million, ending a previous three-week market dominated by strong positive sentiment.
In terms of specific funds, the ARK21 Shares Bitcoin ETF recorded the largest weekly net redemption, reaching US$234.2 million. The Grayscale Bitcoin Trust ETF followed closely with redemptions of $129.1 million, while BlackRock's iShares Bitcoin Trust ETF and Fidelity's Wise Origin Bitcoin Fund recorded weekly outflows of $52.5 million and $50.7 million, respectively.
Despite last week's reversal, the overall spot Bitcoin ETF maintained a net inflow status in September. As of Friday, the funds had accumulated net inflows of approximately $307.3 million this month.
Ether ETF reversed trend to achieve net inflows
In sharp contrast to consistent outflows from Bitcoin funds, the U.S. spot Ether ETF experienced almost the opposite trend. During the same four-day cycle, Ether-focused ETFs attracted net inflows of $196.9 million, according to Farside Investors.
The flow of funds in the Ether ETF fluctuated widely at the beginning of the week: US$24.3 million flowed out on Tuesday, US$34.7 million flowed in on Wednesday, and another US$29.9 million flowed out on Thursday. However, the market turned positive on Friday, with net inflows reaching $216.4 million in a single day, putting a positive end to the week.
BlackRock's iShares Ethereum Trust ETF led trading activity on Friday, attracting $148.8 million in inflows. The 21Shares core Ethereum ETF followed closely, increasing $29.1 million on the day.
Noun explanation: Exchange-traded funds (ETFs), an investment fund tool that tracks the value of underlying assets and is traded on traditional stock exchanges, allowing investors to gain exposure to relevant assets without having to directly hold assets.
With the above developments, the U.S. spot Ether ETF overcame market volatility at the beginning of the week and ended the week with strong net inflows, which is in sharp contrast to the recent trend of Bitcoin ETFs.
