What’s Fueling Ethereum ETF Gains Over Bitcoin in 2026?

Ethereum ETFs attracted 37,959 ETH, worth roughly $71.17 million, during the seven days ending July 28, while Bitcoin ETFs recorded net outflows of 3,170 BTC, equivalent to about $200.23 million, over the same period.

The divergence, highlighted by Lookonchain using CoinGlass data, marks Ethereum ETFs’ third consecutive week of inflows and raises a broader question: is this simply a short-term portfolio rotation, or does it signal a deeper shift in how institutions are allocating capital across crypto assets?

The answer appears to be a mix of both. However, the forces behind Ethereum’s recent strength and Bitcoin’s ETF weakness are different. Bitcoin ETFs still maintain a much larger asset base, and Ethereum’s recent momentum follows months of pressure from earlier outflows. While the trend is notable, it is too early to call it a complete change in institutional strategy.

Fund Flows Reveal Ethereum’s Growing Momentum

A closer look at individual funds highlights the difference between the two markets. BlackRock’s IBIT, the largest spot Bitcoin ETF by assets, saw outflows of 3,511 BTC last week, surpassing the entire Bitcoin ETF category’s net decline of 3,170 BTC.

Other Bitcoin products also experienced mixed results. Grayscale’s Bitcoin funds lost 10 BTC, while Bitwise’s BITB declined by 27 BTC. Fidelity’s FBTC gained 109 BTC, and ARK 21Shares’ ARKB added 77 BTC, but those inflows were insufficient to reverse the broader selling pressure.

Ethereum ETF activity was heavily concentrated around BlackRock’s ETHA. The fund absorbed 37,424 ETH of the category’s total 37,959 ETH inflows, accounting for nearly all of the weekly gains.

Grayscale’s Ethereum products added 5,515 ETH, while Fidelity’s FETH recorded a 4,980 ETH outflow, nearly offsetting Grayscale’s increase. ETHA’s dominance reflects its market position, controlling around 68% of U.S. spot Ethereum ETF assets and offering a more competitive fee structure than older Grayscale products. Institutional investors continue to favor funds with stronger liquidity and lower costs, giving ETHA a clear advantage.

Bitcoin traded around $63,900, gaining approximately 4% over the week despite ETF outflows. The disconnect between price movement and ETF activity is not unusual, as fund withdrawals can often reflect rebalancing strategies rather than outright bearish sentiment.

Bitcoin’s recent volatility near the $64,000 level has also coincided with significant liquidation events, suggesting some ETF outflows may be linked to market positioning changes rather than a broader loss of confidence.

Ethereum Attracts Fresh Institutional Interest

Despite Ethereum’s recent gains, Bitcoin ETFs remain far ahead in terms of scale, holding about $76.22 billion in assets compared with Ethereum ETFs’ $9.72 billion. The more than sevenfold gap means Ethereum is still far from challenging Bitcoin’s institutional dominance.

However, the latest flows show that new money entering the crypto ETF market is increasingly moving toward Ethereum.

Bitcoin ETFs have recovered only around 3.3% of the $8.2 billion in outflows recorded through mid-July. Continued withdrawals from major funds like IBIT suggest the category has not yet fully regained momentum.

Ethereum ETFs, meanwhile, generated $103.9 million in net inflows for the week ending July 24, leading all spot crypto ETF products during that period. Three straight weeks of positive flows after a difficult start to the year suggest renewed institutional interest rather than a temporary anomaly.

Ethereum’s momentum is also being reinforced by corporate treasury demand. BitMine shares jumped 13% as investors responded positively to its Ethereum-focused treasury strategy, while SharpLink Gaming continued expanding its ETH holdings despite market volatility.

The combination of sustained ETF demand and corporate accumulation suggests Ethereum’s recent outperformance may represent more than a short-term rotation, potentially pointing toward a gradual shift in institutional crypto allocation trends.
