Asset management giant BlackRock launched the “iShares Staked Ethereum Trust ETF (ETHB)” on Thursday. On its first day of trading, it achieved impressive results, with a trading volume exceeding $15.5 million, marking a new milestone for institutional investment in the Ethereum ecosystem.
Bloomberg ETF analyst James Seyffart posted on social platform X: “Most of the trading has already been completed, with a trading volume of $15.5 million.”
He added that, for a first-day ETF launch, this is definitely a “very solid start.” Additionally, Seyffart also revealed earlier that ETHB’s asset size at launch had already exceeded $100 million.

ETHB is BlackRock’s third cryptocurrency ETF and also the company’s first product to incorporate staking mechanisms into its structure.
Specifically, ETHB will hold Ethereum spot assets directly and stake a portion of the ETH. In other words, investors can participate in Ethereum price movements directly and also enjoy staking rewards.
In fact, BlackRock hinted as early as 2025 that it was interested in entering the “staking crypto ETF” blue ocean. According to the latest S-1 registration statement filed with the U.S. Securities and Exchange Commission (SEC), BlackRock quietly accumulated Ethereum in the market as early as February this year to pave the way for ETHB’s listing.
Operationally, under normal market conditions, ETHB will stake between 70% and 95% of its ETH holdings and keep the remaining 5% to 30% to meet fund subscription, redemption, and daily liquidity needs.
Regarding the most concerned “income distribution mechanism,” approximately 82% of staking rewards will be paid monthly to ETF holders; the remaining 18% will be distributed to the issuer and the executing agent.
