BlackRock's iShares Staked Ethereum Trust ETF (ETHB) is bucking the trend as other Ethereum ETFs experience net outflows. On March 20, 2026, Ethereum spot ETFs saw a total net outflow of $41.97 million, marking the third consecutive day of net outflows. However, BlackRock's ETHB stood out with a net inflow of $5.47 million, making it the Ethereum spot ETF with the largest single-day net inflow.
ETHB's success can be attributed to its staking mechanism. The fund stakes between 70% and 95% of its ether holdings, distributing approximately 82% of the gross staking rewards to investors monthly. BlackRock and Coinbase retain the remaining 18% as a staking service fee. This approach allows investors to participate in staking rewards without the operational complexities of direct ETH staking.
Launched on March 12, 2026, ETHB quickly amassed $254 million in assets under management within its first week. The fund provides investors with exposure to ether within a traditional brokerage account, offering a convenient way to access the Ethereum ecosystem. The ETF launched with $107 million in assets, with roughly 80% already staked on-chain.
BlackRock is temporarily waiving a portion of the sponsor fee for the first 12 months, setting it at 0.12% of the net asset value for the first $2.5 billion of the Trust's assets. After this period, the sponsor's fee will be 0.25%. ETHB's ability to attract inflows while other Ethereum ETFs face outflows highlights the growing interest in staking and yield-generating crypto products.
