ETHB: Everything We Know About BlackRock's New Ethereum Staking ETF

‍

BlackRock is increasing preparations for the launch of its iShares Staked Ethereum Trust, which will trade under the ticker ETHB. 

The world’s largest asset manager has filed for the product following the success of its spot Ethereum ETF, ETHA, which has already amassed over $6 billion in assets. An SEC filing from 17th December shows that a BlackRock “Seed Capital Investor” has bought 4,000 shares at $0.25. This initial capital will be used as initial capital for the fund. 

No official launch date is set but it is likely to be launched in the first half of 2026. This follows a shift in regulatory sentiment that now permits staking rewards to be incorporated into exchange-traded products, a move previously considered unfeasible by the SEC.

The ETHB ETF is designed to transform Ethereum from a passive asset into a total-return product. According to the latest filings:

• Staking Ratio: BlackRock intends to stake between 70% and 95% of the Ether held by the trust. To manage the 95% staking target, BlackRock will maintain a "Liquidity Sleeve" of 5-30% in unstaked ETH. This buffer ensures the fund can meet redemptions even when the majority of assets are locked.

• Revenue Split: The fund will share 82% of staking rewards with investors, while the remaining 18% is split between BlackRock and its prime execution agent, Coinbase.

• Fees: The trust will carry a 0.25% sponsor fee in addition to the cut taken from gross staking rewards.

‍Tracking ETHB on Arkham

Just like existing spot ETFs, investors can track ETHB’s performance and holdings in real-time via the Arkham Intel Platform. BlackRock is currently the 4th largest entity on Arkham, with over $57 billion in on-chain holdings as of February 2026.

Traders should note that because of T+1 settlement in traditional finance, on-chain evidence of BlackRock's ETH purchases typically appears one business day after the initial trade. Monitoring BlackRock’s entity page allows users to observe these massive movements of capital as they settle on the blockchain.

Despite a "crypto winter" that has seen Ethereum's price dip below $2,000, institutional integration into DeFi is expanding. The launch of ETHB will be a pivotal moment where institutional yield-seeking meets decentralized infrastructure.
