US spot Ethereum ETFs attracted $1.75 billion in August 2026, their strongest monthly inflow since August 2025, after losing more than $1 billion across May and June. About $1.42 billion arrived during a nine- to 10-session run that began around August 17, including a record daily inflow of $225.8 million on August 27. BlackRock's ETHA accounted for roughly 72% of the monthly surge, or about $1.02 billion, while Fidelity's FETH and BlackRock's staking-enabled ETHB supplied most of the remainder. The inflows were driven largely by institutional and traditional-finance channels, with lower Treasury yields and improved digital-asset regulation reducing some barriers to allocation. Since the July 2024 launch, cumulative net inflows into US spot Ethereum ETFs have reached approximately $12 billion to $13 billion, while category assets under management stood between $12 billion and $15 billion as of August 2026. ETHB also highlights Ethereum's proof-of-stake-based staking rewards, giving its ETF structure a yield component that Bitcoin products do not have.
