Ether ETFs Surge to a Record of $2.85B While Bitcoin Trails

• Ethereum ETFs set a new record with $2.85 billion in inflows within a single week.
• Bitcoin ETFs showcased gains, posting $548 million, but trailed behind Ethereum. 
• Institutional focus turned stronger toward Ethereum as its ETF assets multiplied.

Ethereum exchange-traded funds (ETFs) surged to record inflows of $2.85 billion last week, marking their strongest performance to date, while Bitcoin ETFs attracted $548 million, signaling weaker momentum. The analysis is conducted between August 11 to 15, marking a pivotal point in the competition between Bitcoin and Ethereum ETFs.

Record-Breaking Ethereum Inflows

Dominating the market, BlackRock’s ETHA spearheaded the inflows, capturing $2.32 billion, while Fidelity’s FETH added $361.23 million. Grayscale’s Ether Mini Trust secured $219.58 million, although its ETHE counterpart posted a $71.57 million outflow.

Further, Vaneck’s ETHV contributed $14.36 million, Franklin’s EZET registered $8.48 million, Invesco’s QETH added $2.26 million, and 21Shares’ CETH captured $1.26 million. Collectively, these inflows created Ethereum’s largest single-week accumulation, confirming heightened institutional interest in Ether-based products.

Ethereum also recorded its largest daily inflow ever on August 11, with $1.02 billion. Later, on August 13, the second-largest daily inflow of $729 million was witnessed. This sequence of gains boosted Ethereum ETF net assets to $28.15 billion, now accounting for 5.3% of the asset’s total market capitalization.

Bitcoin’s Inflows Fall Short

As Ethereum ETFs gained the upper hand, Bitcoin ETFs trailed, although they showcased significant gains. BlackRock’s IBIT led inflows with $887.82 million, while Grayscale’s Bitcoin Mini Trust captured $32.97 million. Invesco’s BTCO followed with $4.90 million. Despite these entries, outflows weighed heavily on the sector. Ark 21Shares’ ARKB faced redemptions of $183.92 million, Grayscale’s GBTC shed $95.96 million, Fidelity’s FBTC posted $73.78 million in outflows, Bitwise’s BITB lost $18.36 million, and Vaneck’s HODL declined by $5.85 million.

The week came to a close with Bitcoin ETFs pulling in $547.82 million in net inflows amid market volatility. Trading volume hit $20.8 billion, more than Ethereum, scoring net inflows with relatively stronger consistency. In view, total ETF assets for Bitcoin grew to $150.89 billion, thereby establishing its dominance. However, the inflows never rose above the $500 million level, thus limiting their momentum within the week. 

Ethereum’s ETF growth is being attributed to the decentralized finance ecosystem and the use of smart contracts. Analysts report that investors view the Ethereum-based products as scalable and liquid investment options, and the demand enabled the wholesalers to widen their product offerings with the inclusion of NEOS’ High Income Ethereum ETF, which uses liquidity as an investment strategy. With billions flowing into Ethereum ETFs, institutions are finding new foundations for long-term exposure.

Comparative performance shows stronger inflows into Ethereum ETFs, most prominently in July and August 2025, when there were repeated inflows of over a billion. While Bitcoin ETFs rank larger in scale, they decline in terms of consistent flows and investor appetite. Overall, the data points to a changing landscape where Ethereum ETF offerings are progressively positioning themselves to be the institutional alternative to Bitcoin.
