BlackRock’s Ethereum Exchange Traded Funds (ETFs), including the iShares Ethereum Trust (ETHA) and the iShares Staked Ethereum Trust ETF (ETHB), have demonstrated significant asset accumulation and captured substantial market share within the US spot Ethereum ETF landscape. By late September 2026, ETHA alone had amassed over $13 billion in net inflows since its inception in July 2024, establishing BlackRock as a leading entity in this evolving sector.
On September 28, the iShares Ethereum Trust (ETHA) recorded net inflows of $15.35 million, equivalent to approximately 5,730 ETH. This daily inflow contributed to a strong weekly performance, with ETHA attracting $326 million in net capital for the week ending September 28. This figure represents nearly half of the total $690 million gathered by all US spot Ethereum ETFs combined during the same period.
The overall US spot Ethereum ETF market reached approximately $17.78 billion in assets under management by late September 2026. ETHA’s substantial inflows have secured it a significant portion of this market. The pace of accumulation, with ETHA gathering over $13 billion in roughly two years since its July 2024 launch, highlights robust investor demand for regulated Ethereum investment products.
BlackRock also introduced the iShares Staked Ethereum Trust ETF (ETHB) in March 2026. This ETF provides investors with exposure to Ethereum’s staking yield, enabling them to earn consensus rewards without the complexities of running a validator node. ETHB has maintained consistent investor interest since its launch, notably achieving zero outflow days—meaning that on no trading day has more capital exited the fund than entered it.
Collectively, ETHA and ETHB represent approximately 5.4% of Ethereum’s total market capitalization as of late September 2026. The strong performance and significant asset gathering by BlackRock’s Ethereum ETFs indicate a growing investor appetite for regulated digital asset investment vehicles and underscore the increasing maturity of the cryptocurrency market.
