Bitcoin Spot ETFs Lose $463M as Ether ETFs Attract $197M

US spot Bitcoin exchange-traded funds (ETFs) saw a sharp weekly reversal, posting $462.7 million in net outflows after three straight weeks of inflows. The shift came across all four trading sessions from Tuesday through Friday, according to data from Farside Investors, with the selling extending the slide into a fourth consecutive day.
Ether ETFs moved in the opposite direction over the same period, recording nearly $197 million in net inflows. Farside Investors reported that US spot Ether products drew $196.9 million during the four-day window, even as flows were choppy earlier in the week.
Key takeaways

US spot Bitcoin ETFs recorded $462.7 million net outflows for the four-session week, reversing a three-week inflow streak.
Bitcoin ETF outflows were broad-based across sessions, with Thursday’s $282.7 million withdrawal the largest daily outflow since July.
Despite the weekly reversal, spot Bitcoin ETFs remain net positive for September, with $307.3 million in inflows through Friday.
US spot Ether ETFs delivered $196.9 million in net inflows, led on Friday by BlackRock’s iShares Ethereum Trust ETF with $148.8 million.

Bitcoin ETFs reverse course after three-week inflow run
According to Farside Investors, Bitcoin ETF outflows unfolded across every session from Tuesday to Friday. The withdrawal week followed what the market data described as the strongest three-week inflow stretch of 2026, which ended after funds shed $166.8 million during the first two days of the holiday-shortened week.
The pressure intensified on Thursday, when US spot Bitcoin ETFs posted net outflows of $282.7 million—reported as the largest daily withdrawal since July. Friday’s outflow slowed to $13.2 million, but SoSoValue data indicates it still extended the streak of negative daily flows to four trading days.
That combination—one very large day followed by continued (though smaller) withdrawals—helps explain why the weekly total turned decisively negative. Investors watching ETF flows typically treat these reversals as short-term signals of changing risk appetite, especially when they break prior momentum rather than merely pausing inflows.
Which funds drove weekly Bitcoin outflows
Farside Investors’ breakdown shows that ARK 21Shares’ Bitcoin ETF led the weekly withdrawals with $234.2 million in net outflows. Grayscale’s Bitcoin Trust ETF followed with $129.1 million.
BlackRock’s iShares Bitcoin Trust ETF also saw withdrawals, losing $52.5 million over the week. Fidelity’s Wise Origin Bitcoin Fund recorded net outflows of $50.7 million. Together, the results suggest the reversal was not isolated to a single product—multiple major issuers posted negative weekly flow.
While daily volatility can be normal for ETF baskets, the fact that several large operators posted sizable weekly declines is notable for traders who monitor whether outflows are concentrated (often linked to specific investor behavior) or distributed across the complex.
Broader flow picture: still net positive for September
Even after the weekly reversal, spot Bitcoin ETFs remain in positive flow territory for the month. According to the report, through Friday these products have accumulated about $307.3 million in net inflows for September.
That matters because it changes how the week’s news may be interpreted. A negative week can reflect temporary positioning or macro-driven caution, but a still-positive month indicates that large inflows have not fully disappeared across the broader period. For market participants, the key question going forward is whether the ETF complex can stabilize its daily flows before monthly net gains start to erode.
Ether ETFs turn positive with strong Friday inflows
On the Ether side, US spot Ether ETFs recorded $196.9 million in net inflows over the same Tuesday-to-Friday period, per Farside Investors. The week’s flow pattern looked more uneven earlier, with $24.3 million in outflows on Tuesday, $34.7 million in inflows on Wednesday, and $29.9 million in outflows on Thursday.
Friday marked the turning point. The Ether funds drew $216.4 million in net inflows, flipping the four-day total into positive territory despite the earlier back-and-forth.
Product leadership also differed by day. BlackRock’s iShares Ethereum Trust ETF drove Friday’s inflows with $148.8 million, while 21Shares Core Ethereum ETF added $29.1 million. In practice, such leadership changes can help investors gauge where incremental demand is showing up within the Ether ETF lineup.
Overall, the contrast between Bitcoin’s outflows and Ether’s inflows in the same calendar window underscores how different investor demand can be across the two major spot ETF ecosystems. Rather than assuming flows will always move together, traders often watch whether capital rotates between Bitcoin and Ether depending on positioning, risk appetite, and broader market sentiment.
Looking ahead, the next signals to monitor are whether Bitcoin ETF outflows persist after the Thursday-heavy withdrawal day and whether Ether’s strong Friday inflow momentum can sustain through the following week—because the month-to-date net picture remains supportive for Bitcoin while Ether’s reversal will be tested by the next few sessions’ flow consistency.
