BlackRock’s ETHB Tops $1 Billion, Highlighting Rise of Staking-Enabled Ether ETFs

BlackRock’s iShares Staked Ethereum Trust ETF, trading under the ticker ETHB, has crossed $1 billion in assets under management, marking an early milestone for a fund built to give investors exposure to ether while also generating staking income. Separate tracker data indicate the fund accumulated about $251.4 million worth of ETH over the last 20 trading days, with no daily outflows during that stretch.

That narrower accumulation figure is important because a widely circulated claim that ETHB drew $307.7 million over 20 straight inflow days could not be independently verified through BlackRock materials or the primary market trackers reviewed. The best-supported recent number comes from blockchain intelligence platform Arkham, which said, “Over the last 20 trading days, ETHB has bought $251.4M of ETH. It has not had a single day of outflows.” That should be treated as tracker and on-chain intelligence data, not issuer-reported fund flows.

ETHB is a staking-enabled Ether exchange-traded fund, meaning it is designed to hold ether and earn staking rewards on a portion of those holdings in addition to tracking the cryptocurrency’s market price. BlackRock product materials show the fund launched in mid-March 2026. In the firm’s product brief, BlackRock says the trust “Seeks to reflect the performance of the price of ether, as well as rewards from staking a portion of the Trust’s ether.”

BlackRock’s own fund listing supports the $1 billion asset milestone. A product listing snapshot dated Aug. 31, 2026, showed ETHB with about $1,051,809,438 in assets under management. That makes ETHB notable not just as another crypto fund, but as one of the first U.S.-listed products structured to combine spot Ether exposure with staking rewards in an ETF-like wrapper.

Staking-based crypto trusts became more feasible in the United States after IRS/Treasury Revenue Procedure 2025-31, issued in November 2025, created a safe harbor for certain exchange-listed trusts to stake digital assets without necessarily losing grantor-trust tax treatment. Products like ETHB are closely watched because they package crypto exposure with staking yield, and because staking can reduce the amount of ETH immediately available for trading.
