BlackRock’s Ethereum exchange-traded fund, ETHA, has shot past $10 billion in assets under management. It is now one of the fastest-growing ETFs ever, joining two other cryptocurrency funds in the ranks.BlackRock’s ETHA Achieved $10 Billion AUM Milestone In Just 251 DaysBlackRock’s ETHA has become the third-fastest exchange-traded fund to break the $10 billion milestone just a year since its launch, Bloomberg’s senior ETF analyst Eric Balchunasnotedon Thursday. The only other two funds to reach this milestone in a similar timeframe have been BlackRock’s spot Bitcoin ETF (IBIT) and Fidelity’s spot Bitcoin ETF (FBTC).ETHA took just 251 days to hit $10 billion, an impressive feat in the ETF world, where it typically takes years to build that kind of scale. ETHA’s sprint from $5 billion to $10 billion took place in just 10 days, which Balchunas described as the “equivalent of a God candle” in ETF inflow terms.“LOOK OUT: $ETHA just hit $10b in one year flat, the 3rd fastest ETF to hit that mark in history after (you guessed it) two bitcoin ETFs $IBIT & $FBTC,” hewrote. “Amazingly it went from $5b to $10b in just 10 days (ETF asset equiv of a God candle). Is in Top 5 in flows 1M, 1W.”The milestone puts ETHA well ahead of the JPMorgan Nasdaq Equity Premium Income ETF (JEPQ), which took 444 days to reach the $10 billion mark and currently ranks as the fourth fastest-growing ETF in history.Nate Geraci, the president of NovaDius Wealth Management, observed that the three fastest ETFs to reach $10 billion are now all spot crypto-based ETFs, highlighting their unprecedented growth pace compared to traditional finance products.“We’re talking about an ETF industry that’s been around for over 3 decades and has nearly 4,400 products,” Geraciquippedin a post on X.Growing Ether ETF Demand Signals Institutional ConfidenceSpot Ether ETFs, which now typically register daily net inflows of over $500 million, have been stealing the spotlight from their older BTC-denominated cousins in July.Datafrom SoSoValue shows that the nine U.S.-listed Ether ETFs enjoyed a 14-day positive inflow streak, with inflows totaling $4.4 billion since July 3– reinforcing long-term bullish sentiment.
