Ethereum ETFs Draw 17-Day Cash Surge as BlackRock Fund Joins Top Tier

U.S. spot Ethereum exchange-traded funds notched their 17th straight day of inflows on 28 July

U.S. spot Ethereum exchange-traded funds notched their 17th straight day of inflows on 28 July, pulling in about $65 million and lifting the month-to-date haul to almost $5.2 billion. Data compiled by Farside Investors show cumulative July inflows into the category at roughly $9.3 billion through 25 July—120 percent more than at the start of the month—leaving funds on course to breach the $10 billion mark before month-end.

BlackRocks iShares Ethereum Trust (ticker ETHA) has driven the surge. The vehicle absorbed an estimated $3.9 billion over the past 30 days, making it the fourth-largest U.S. ETF by net inflows across all asset classes, according to Bloomberg and Farside figures. Fund disclosures indicate BlackRock added about $132 million of ether on 29 July alone, underscoring rising institutional appetite for the token.

Bitcoin products remain in demand but have ceded momentum. Spot Bitcoin ETFs logged $157 million of net purchases on 28 July—$147 million of which went into BlackRocks IBIT—after attracting a record $1.179 billion on 10 July and $2.39 billion during the week of 14-18 July. By contrast, market trackers show only $73 million flowed into the asset class last week as earlier outflows moderated.

Across the broader digital-asset complex, institutional products hauled in $17.8 billion during the first half of 2025, led by $2.2 billion for Bitcoin funds. The recent pick-up in ether buying, coupled with uninterrupted inflows spanning 11 consecutive weeks, suggests a rotation toward Ethereum as investors look beyond the original cryptocurrency.
