U.S. spot Ethereum exchange-traded funds attracted $2.85 billion of net inflows in the week ended Aug. 15, the largest weekly haul since the products debuted last year and the third-biggest for any digital-asset ETF on record. The surge accounted for 77% of the $3.75 billion that moved into crypto investment products overall, according to fund-flow data compiled by CoinShares. Bitcoin spot ETFs drew $548 million over the same five-day period, underscoring a sharp shift in investor preference toward ether. BlackRock’s iShares Ethereum Trust (ticker ETHA) led the pack with about $2.32 billion of subscriptions and has notched nine consecutive trading days of inflows, bringing its cumulative intake to roughly $8 billion. Total year-to-date inflows into Ethereum ETFs now stand near $11 billion. The buying spree translated into roughly 649,000 ether being absorbed by the funds and helped push the token’s price to around $4,500, briefly touching $4,740 before easing over the weekend. Analysts said the flows highlight deepening institutional participation in the second-largest cryptocurrency as investors diversify beyond bitcoin. Momentum cooled at the start of the new week: preliminary disclosures show Ethereum ETFs suffered $196.6 million of net outflows on Aug. 18, the second-largest single-day withdrawal on record, while Bitcoin ETFs lost $122 million. Ether traded near $4,200 after the pull-back as the market weighed whether the prior week’s record inflows marked the start of a longer trend or a short-term allocation shift.
