US investors have poured more money into spot Ether exchange-traded funds (ETFs) than Bitcoin ETFs over the last six trading days, as institutional interest in Ethereum picked up sharply this week.
The shift happened in the United States, with Ether ETFs collecting a net inflow of $2.39 billion, while spot Bitcoin ETFs only brought in $827 million during the same time, according to data from Farside Investors. This marks a rare moment where Ethereum has taken the lead in ETF flows for six straight days.
The biggest winner was BlackRock’s iShares Ethereum ETF (ETHA), which received a total of $1.79 billion, representing nearly 75% of all Ethereum ETF investments during the period. ETHA recently became the third-fastest ETF in history to reach $10 billion in assets under management, accomplishing this in just 251 trading days.
Fidelity’s Ethereum Fund (FETH) also had a strong showing, recording its best-ever day on Thursday with a $210 million net inflow. That beat its previous daily record of $202 million, set on December 10, 2024. The performance demonstrates broadening institutional appetite beyond BlackRock’s dominant market position.
On the flip side, Bitcoin ETFs saw a slowdown. After enjoying 12 straight days of net inflows, totaling $6.6 billion, the streak ended on Monday with a net outflow of $131 million.
This was a sharp contrast to the enthusiasm seen earlier in the month for Bitcoin ETFs. The change in investor behavior suggests that they are now focusing more on Ethereum, especially from large players.
The shift indicates strategic asset allocation changes among institutional investors who are increasingly viewing Ethereum and Bitcoin as distinct investment categories with different risk-return profiles.
Corporate Ethereum holdings have reached 2.31 million ETH, representing 1.91% of the total supply, according to Strategic Ether Reserves tracking data. BitMine Immersion Technologies, a major corporate buyer, purchased $2 billion worth of Ether in just 16 days. This move made BitMine the largest corporate holder of ETH.
This institutional accumulation coincides with the ETF flow trends, suggesting coordinated institutional positioning across multiple investment vehicles.
The corporate treasury adoption parallels similar Bitcoin strategies but focuses on Ethereum’s utility in decentralized finance and smart contract applications rather than purely store-of-value propositions.
Galaxy Digital CEO Michael Novogratz believes Ethereum could reach $4,000 and outperform Bitcoin in the next six months. “ETH will outperform BTC,” he said. The forecast reflects growing institutional confidence in Ethereum’s fundamental value drivers beyond speculative trading.
The sustained ETF inflow reversal may signal a broader institutional recognition of Ethereum’s expanding utility in tokenization, DeFi, and enterprise blockchain applications. However, ETF flow patterns remain subject to significant volatility and market sentiment shifts.
Current trends suggest institutional portfolios are evolving toward multi-asset crypto strategies rather than Bitcoin-only approaches, potentially establishing Ethereum as a complementary institutional holding.
