Bitcoin ETFs Lose $463M as Ethereum ETFs Gain $197M
US spot Bitcoin ETFs recorded $462.7 million in net outflows from 8 to 11 September, ending the strongest three-week inflow streak of 2026. Outflows peaked at $282.7 million on Thursday, the largest daily withdrawal since July, before slowing to $13.2 million on Friday.
ARK 21Shares Bitcoin ETF led withdrawals with $234.2 million, followed by Grayscale Bitcoin Trust ETF with $129.1 million. BlackRock’s iShares Bitcoin Trust ETF and Fidelity’s Wise Origin Bitcoin Fund lost $52.5 million and $50.7 million, respectively. Despite the reversal, Bitcoin ETFs retained about $307.3 million in net inflows for September and have attracted more than $55 billion since launching in January 2024.
Bitcoin traded near $77,900 after failing to hold above the psychologically important $80,000 level. Ethereum ETFs moved in the opposite direction, attracting $196.9 million during the same period, including $216.4 million on Friday. BlackRock’s Ethereum ETF accounted for $148.8 million of that daily inflow.
Traders are watching the Federal Reserve’s 16 September rate decision. Inflation concerns and expectations of tighter monetary policy could pressure risk assets and Bitcoin ETF flows in the short term. However, the large cumulative inflows and relatively small scale of the latest withdrawals leave the longer-term institutional demand trend intact.
Bearish
The immediate price signal is bearish for BTC. Bitcoin ETF outflows accelerated to $462.7 million, while BTC failed to reclaim the $80,000 level. Expectations of tighter Federal Reserve policy can raise Treasury yields and the opportunity cost of holding a non-yielding asset such as Bitcoin, potentially encouraging further selling and short-term volatility.
The impact is not uniformly negative across the broader crypto market. Ethereum ETFs attracted $196.9 million, indicating selective institutional demand rather than a complete withdrawal from digital assets. Bitcoin’s September flows remain positive, and cumulative ETF inflows above $55 billion support the longer-term adoption case. Historically, ETF outflows around major central-bank decisions can create temporary downside pressure, but sustained weakness would require continued redemptions, a stronger dollar or a broader deterioration in risk sentiment. Therefore, the near-term trading bias is bearish, while the long-term impact is more neutral.
