Institutional demand for Ether is accelerating, with assets held by spot Ethereum exchange-traded funds surpassing $30 billion, according to multiple fund-flow trackers. When combined with the tokens parked in public company treasuries, the total climbs above $51 billion—equivalent to almost a tenth of the cryptocurrency’s circulating supply. BlackRock is at the forefront of the buying spree. The asset manager’s iShares Ethereum ETF attracted about $968 million of net subscriptions in the past week, placing it second only to the Vanguard S&P 500 ETF for inflows across more than 4,400 U.S. funds. Separate blockchain-ledger data show BlackRock also lifted 15,006 ETH worth roughly $67 million off exchanges on 29 Aug, alongside a purchase of 568 bitcoin valued at $63 million. Across the industry, Ethereum ETFs are on pace for roughly $4 billion of new money in August, while Bitcoin products have leaked cash. Over the last five trading sessions alone, spot Ether funds drew $1.83 billion—about ten times the haul for comparable Bitcoin vehicles. Blockchain analytics firm Glassnode adds that Ethereum’s realised market capitalisation has grown 9.4 % over the past month, outstripping Bitcoin’s 2.6 % gain and reflecting the sustained inflows. The swelling ETF demand comes as Ether trades near record highs and market participants look ahead to potential U.S. approval of staking-based products. For now, the rapid accumulation by heavyweight issuers underscores a shift in institutional preference toward the world’s second-largest digital asset.
