Summary
Cumulative net inflows into US spot Bitcoin ETFs have reached roughly $57–58 billion since the funds launched in January 2024, and total assets under management across the group have surpassed $100 billion. Bitcoin was trading in a range of $80,000 to $81,500 in late October, per the research findings cited by the publisher.
Spot Ethereum ETFs moved in the opposite direction, shedding $21.41 million on October 28. The outflow extended a pattern of consecutive withdrawals, and BlackRock's Ethereum fund, ETHA, was identified as a significant driver. Ethereum ETF outflows approached $1.3 billion for October as a whole. Spot Ethereum ETFs, which debuted in July 2024, have accumulated about $12.5 billion in cumulative net inflows since inception, with total assets of around $14 billion.
The month has been volatile for both products. Mid-October saw a $635 million outflow from Bitcoin ETFs, far larger than the $137 million inflow on October 28, and the turbulence coincided with a sharp increase in Ethereum outflows. The publisher notes that roughly $1.3 billion leaving a product group holding about $14 billion in a single month is significant. BlackRock's presence on both sides of the trade suggests dominant issuers can absorb rotation without losing clients, while smaller issuers more dependent on a single product may experience the swings more sharply.
