Spot Bitcoin ETFs saw $463M in outflows last week as Ethereum ETFs gained $197M. Track the latest institutional capital rotation trends and price levels.

Spot Bitcoin ETFs recorded $462.7 million in net outflows during the week ending September 11, 2026, while Ethereum-focused products attracted $196.9 million in net inflows, signaling a shift in institutional capital allocation [3]. This divergence marks a reversal of recent trends, ending a three-week positive streak for Bitcoin funds and highlighting a period of volatility in digital asset investment vehicles [3].

## Institutional capital shifts
The recent outflow from Bitcoin ETFs was consistent across four consecutive trading days, with Thursday seeing the largest single-day withdrawal of $282.7 million, the highest since July [3]. The ARK 21Shares Bitcoin ETF led the redemptions with $234.2 million, followed by Grayscale’s Bitcoin Trust at $129.1 million [3]. Despite this weekly reversal, Bitcoin ETFs remain net positive for September, with approximately $307.3 million in cumulative inflows for the month [3].

In contrast, Ethereum ETFs saw a surge in interest, particularly on Friday, when BlackRock’s iShares Ethereum Trust captured $148.8 million in fresh capital [3]. This activity aligns with a broader third-quarter trend where the ETH/BTC ratio has climbed more than 25%, marking its strongest quarterly performance since Q3 2025 [3]. Ethereum’s quarter-to-date return on investment is nearing 60%, approaching its historical Q3 peak of over 66% [3].

## Price performance and technical context
While ETF flows suggest a rotation, price action remains mixed. Bitcoin recently declined to $76,370 before finding support above its 100-hour moving average of $77,290 [3]. As of Monday morning, the asset was trading near $78,200, attempting to advance toward its 200-hour moving average of $78,151 [3]. 

Ethereum experienced a sharper decline to $2,402 before rallying 7.75% to $2,666, though that momentum faded as prices retreated to approximately $2,510 [3]. This level places Ethereum barely above its converged 100- and 200-hour moving averages, which sit at $2,494 and $2,497 respectively [3]. Analysts note that while Ethereum has delivered stronger price growth in recent weeks—up 33.04% from August 11 to September 10 compared to Bitcoin’s 22.96%—the year-to-date performance remains negative for both assets [2].

## What to watch
*   **Moving Average Convergence:** Monitor whether Bitcoin can sustain its position above the $78,151 level and if Ethereum holds its support at the $2,494–$2,497 range [3].
*   **ETF Flow Persistence:** Watch for whether the recent Bitcoin outflows represent a sustained trend or a temporary correction, given that the asset remains net positive for the month of September [3].
*   **Quarterly Benchmarks:** Track whether Ethereum’s quarter-to-date return on investment exceeds its historical Q3 peak of 66% as the quarter concludes [3].

The current divergence in ETF flows suggests that institutional appetite is shifting, yet the lack of a clear, sustained price breakout for either asset leaves the market’s direction uncertain. Whether this capital rotation persists will depend on whether Bitcoin can erase its year-to-date ETF deficit or if Ethereum maintains its recent momentum in the final weeks of the quarter [2, 3].
