United States spot Bitcoin exchange-traded funds witnessed $462.7 million in net capital withdrawals over the past week, terminating a three-week period of positive flows. Simultaneously, Ethereum-focused ETFs attracted $196.9 million, prompting speculation about potential institutional capital reallocation.
The hemorrhaging from Bitcoin ETFs persisted through four consecutive trading days, spanning Tuesday to Friday. The most severe exodus occurred on Thursday, when $282.7 million departed Bitcoin investment vehicles in just one sessionārepresenting the largest single-day withdrawal since July.
The ARK 21Shares Bitcoin ETF experienced the heaviest redemptions at $234.2 million in net outflows. Grayscale’s Bitcoin Trust ETF came next with $129.1 million in withdrawals. BlackRock’s iShares Bitcoin Trust ETF recorded $52.5 million in outflows, while Fidelity’s Wise Origin Bitcoin Fund saw $50.7 million exit the fund.
Notwithstanding last week’s negative trend, Bitcoin ETFs maintain a positive position for September as a whole, registering approximately $307.3 million in cumulative net inflows for the month.
Ethereum ETFs Capture Consistent Capital
Regarding Ethereum-based products, capital movements showed inconsistency during the week’s beginning before experiencing a pronounced positive shift on Friday. BlackRock’s iShares Ethereum Trust ETF dominated that session with $148.8 million in fresh capital, with the 21Shares Core Ethereum ETF adding $29.1 million.
The Ethereum ETF flow patterns align with a more extensive third-quarter trajectory. The ETH/BTC ratio has surged beyond 25% this quarter, representing its most significant quarterly appreciation since the third quarter of 2025. Ethereum’s Q3 investment returns are approaching 60%, narrowly trailing its historic Q3 benchmark of over 66% established the previous year.
Ethereum’s proportion of total cryptocurrency market capitalization has also increased by over 25% on a quarter-to-quarter comparison, whereas Bitcoin’s market dominance expanded by merely 1.5% during the identical timeframe.
Market Prices Remain Ambiguous
Notwithstanding the flow statistics, market valuations for both digital assets have not validated a definitive rotation.
Bitcoin declined to $76,370 throughout the week but discovered support above its 100-hour exponential moving average positioned at $77,290. It has subsequently advanced toward its 200-hour moving average approximating $78,151, with the current price hovering near $78,200 as of Monday morning.
Ethereum plummeted to $2,402 before rebounding aggressively to $2,666, representing an increase of approximately 7.75% within several hours. Nevertheless, that upward movement has since been nearly completely erased, with pricing returning near $2,510, marginally above its converged 100- and 200-hour moving averages at $2,494 and $2,497.
For Ethereum to demonstrate genuine momentum, market observers indicate it must penetrate and maintain elevation above the $2,531 to $2,567 resistance corridor.
Market analysts emphasize that a single week of ETF flow divergence might signify portfolio rebalancing or profit-realization activities rather than a permanent structural shift. Multiple consecutive sessions featuring Ethereum inflows accompanying Bitcoin outflows would be necessary to validate an authentic capital rotation.
Both cryptocurrencies are endeavoring to find equilibrium, though neither has decisively breached critical resistance thresholds.
