BlackRock has purchased $1.5 billion in Ethereum over the past 20 days through its spot ETF products. The asset manager acquired $1.27 billion via ETHA and an additional $296.5 million through ETHB during this period. ETHB has recorded zero outflows throughout the entire 20-day accumulation window, indicating sustained investor demand for the fund. This consistent buying activity across both vehicles highlights continued institutional interest in Ethereum exposure through regulated investment products.
