BlackRock's iShares Ethereum Trust pulled in $15.35 million in net inflows on September 28, extending a week that saw US spot Ethereum ETFs draw roughly $690 million combined. The fund's cumulative inflows have now crossed $13 billion, while its staking-focused sibling has yet to post a single outflow day.
BlackRock's iShares Ethereum Trust, ticker ETHA, pulled in $15.35 million in net inflows on September 28, equal to roughly 5,730 ETH bought in a single day through the asset manager's regulated vehicle.
The September 28 inflow capped a week in which US spot Ethereum ETFs collectively attracted approximately $690 million in net capital. ETHA alone accounted for $326 million of that weekly haul, nearly half the total across all competing products.
By the end of September 2026, ETHA's cumulative net inflows had crossed the $13 billion mark, a pace built up in roughly two years given the product didn't exist before July 2024. The broader Ethereum spot ETF category has reached assets under management of approximately $17.78 billion, with ETHA commanding the lion's share of that figure.
BlackRock has not stopped at plain-vanilla ETH exposure. The firm launched the iShares Staked Ethereum Trust ETF, ticker ETHB, in March 2026. The product offers investors exposure to Ethereum's staking yield on top of price appreciation without running a validator node.
ETHB has posted a remarkable record since launch: zero outflow days, with no session where more money left the fund than entered it. Together, ETHA and ETHB represent about 5.4% of Ethereum's overall market capitalization as of late September 2026.
