Why Are Ethereum ETF Outperforming Bitcoin ETF in 2026?

Ethereum ETFs pulled in 37,959 ETH, roughly $71.17 million, over the seven days ending July 28, while Bitcoin ETFs shed 3,170 BTC worth $200.23 million over the same stretch.

That divergence, reported by Lookonchain using CoinGlass data, marks the third consecutive week of net ETH inflows and raises a direct question: Is this a tactical rotation or the beginning of a structural realignment in institutional crypto allocation?

Bitcoin ETFs hold far greater total assets, and the past three weeks represent a meaningful reversal from earlier in the year when Ethereum ETF products faced sustained outflows. The rotation is real.
