U.S. Spot Ethereum ETFs Log 10 Straight Days of Inflows

BlackRock's iShares Ethereum Trust ETF attracted approximately $1.02 billion in net inflows over nine consecutive U.S. trading sessions between August 17 and August 27, 2026, driving a broader streak of institutional investment into Ethereum exchange-traded products. The sustained buying pushed cumulative net inflows into U.S. spot Ethereum ETFs past $1.42 billion during that period, according to data from Farside Investors and SoSoValue. The inflow streak continued on August 28, with U.S. spot Ethereum ETFs collectively recording another $102.1 million in net inflows. BlackRock's ETHA fund again led the group, attracting approximately $83.8 million. The firm's staking-enabled Ethereum ETF, ETHB, also contributed $42.6 million on the same day. This marked a tenth consecutive session of positive flows for the Ethereum ETF category. The performance stands in sharp contrast to the U.S. spot Bitcoin ETF market. On August 28, Bitcoin funds experienced approximately $202 million in net outflows, ending their own nine-session positive streak. Ark Invest and 21Shares' ARKB saw the largest withdrawal at about $114.89 million, followed by Bitwise's BITB with $49.
