U.S. spot Bitcoin ETFs recorded $731 million in net inflows on September 3, marking their strongest single day since January, according to SoSoValue. BlackRock's IBIT led the group, attracting $454 million of the total.
The inflow figures indicate renewed institutional interest in Bitcoin as a regulated investment vehicle. Ethereum spot ETFs attracted $141 million in inflows on the same day.
BlackRock's dominant share of the inflows underscores the asset manager's influence in digital asset investment products. Sustained demand through one of the world's largest asset managers affects market liquidity.
The ETF flows suggest institutional capital is favoring established cryptocurrencies over a broader rotation into alternative digital assets. Financial institutions continue to view Bitcoin as a core holding rather than a speculative position.
