BlackRock has filed with the SEC to launch the iShares Staked Ethereum Trust, an ETF that plans to stake up to 95% of its Ethereum holdings. Trading under the ticker ETHB, the fund will share 82% of staking rewards with investors, while BlackRock and Coinbase retain 18%. This move marks a significant shift in U.S. policy, now permitting staking rewards in exchange-traded products. The ETF aims to transform Ethereum from a passive asset into a yield-generating investment, offering institutions a way to earn from Ethereum without managing complex staking processes. The fund will maintain a liquidity reserve of 5% to 30% in unstaked ETH to meet redemption demands. BlackRock's initiative follows the success of its spot Ethereum ETF, ETHA, which has amassed over $6 billion in assets. The launch of ETHB is anticipated in the first half of 2026, pending regulatory approval.
