Bitcoin ETF outflows hit $462.7 million last week. Consequently, this reversed three consecutive weeks of inflows. Meanwhile, Ether ETFs moved the opposite way.
Why Bitcoin ETF Outflows Matter
According to Farside Investors, withdrawals ran across all four trading sessions. Specifically, this started Tuesday and ended Friday. Moreover, the outflows followed the strongest three-week inflow run of 2026. That run ended after the funds shed $166.8 million in two days. Furthermore, the selling deepened on Thursday. US spot Bitcoin ETFs recorded $282.7 million in outflows. That was their largest daily withdrawal since July. Friday’s outflow slowed to $13.2 million. Nevertheless, it extended the negative streak to four days.
For example, ARK 21Shares Bitcoin ETF led weekly withdrawals. It recorded $234.2 million in net outflows. Additionally, Grayscale’s Bitcoin Trust ETF followed with $129.1 million. BlackRock’s iShares Bitcoin Trust ETF had $52.5 million in outflows. Similarly, Fidelity’s Wise Origin Bitcoin Fund lost $50.7 million. Despite the reversal, spot Bitcoin ETFs remain positive for September. They have about $307.3 million in net inflows through Friday.
Ether ETFs Record Weekly Inflows
On the other hand, US spot Ether ETFs recorded $196.9 million in net inflows. This happened over the same four-day period. However, the funds had mixed flows earlier in the week. They saw $24.3 million in outflows on Tuesday. Subsequently, Wednesday brought $34.7 million in inflows. Then Thursday saw $29.9 million in outflows. Finally, the week turned positive on Friday. The funds drew $216.4 million in net inflows. For instance, BlackRock’s iShares Ethereum Trust ETF led Friday. It added $148.8 million. Also, the 21Shares Core Ethereum ETF followed with $29.1 million.
In conclusion, these flows show shifting investor sentiment. Bitcoin ETFs faced a sharp reversal. In contrast, Ether ETFs gained momentum. Therefore, market participants will watch next week’s data closely.
