BlackRock’s iShares Ethereum Trust (ETHA) has surpassed $10 billion in assets under management in just 251 days, making it the third-fastest ETF in history to reach that milestone. BlackRock has acquired over 1 million ETH since July 1, 2025, bringing total holdings to 2.8 million ETH worth approximately $10.2 billion as of July 24.
The expansion of BlackRock’s iShares Ethereum Trust (ETHA) has established a new benchmark for the industry. ETHA, which started off, has amassed $10 billion in assets under management (AUM) in only 251 days beating several legacy ETFs.
ETHA’s Record-Breaking Performance
ETHA’s 251-day timeline to $10 billion outpaced established funds like JPMorgan’s Nasdaq Equity Premium Income ETF (JEPQ), which required 444 days to reach the same threshold. The achievement establishes ETHA among elite ETF performers in financial markets history.
Industry observers point out the stunning speed of inflows. ETF Store President Nate Geraci noted that three of the quickest ETFs to reach $10 billion AUM are now cryptos, a testament to a change in investor sentiment and institutional adoption.
Even with ETHA’s push, BlackRock’s iShares Bitcoin Trust (IBIT) remains the quickest growing ETF, having reached $10 billion in a record 34 days after launch in January 2024. Fidelity’s Wise Origin Bitcoin Fund did so in 54 days.
Ethereum Institutional Flow
Ethereum-based ETFs have lately witnessed high demand, posting a 14-day inflow sum of $4.4 billion since July. On the other hand, Bitcoin-based ETFs have posted outflows, terminating a preceding 12-day inflow activity.
BlackRock’s action is part of a larger institutional migration towards Ethereum as a long-term holding. The divergent flow patterns suggest strategic repositioning toward Ethereum as institutions recognize its utility beyond digital currency.
With the migration to proof-of-stake in Ethereum 2.0 and rising application in DeFi and NFTs, Ethereum is becoming an anchor holding in institutional crypto portfolios.
Volatility remains a concern particularly with the growing open interest and leveraged long positions in the altcoins but BlackRock’s ongoing investment underscores rising institutional confidence in Ethereum’s position in the digital asset space.
