Key Takeaways
- • BlackRock operates two distinct Ethereum ETFs: ETHA (spot price exposure only) and ETHB (price exposure plus staking yield), with ETHA holding $6.5 billion in assets as of March 2026 and ranking as the largest U.S. Ethereum ETF by AUM.
- • ETHB, launched March 12, 2026, stakes 70–95% of its ETH holdings and distributes approximately 82% of gross staking rewards to investors monthly, introducing slashing risk as a new consideration absent from ETHA.
- • Both funds charge 0.25% annual sponsor fees and hold real ETH in direct custody through Coinbase Prime, benchmarked against the CME CF Ether-Dollar Reference Rate rather than futures contracts.
- • Staking rewards distributed through ETHB are taxed as ordinary income under current IRS guidance, creating a material tax consideration for institutional and high-net-worth investors.
- • BlackRock's iShares platform captured approximately 95% of all flows into digital asset ETPs in 2025, signaling dominant institutional adoption of crypto exposure products; the firm's broader tokenized asset strategy (BUIDL fund) exceeded $1 billion in AUM by March 2025.
Summary
BlackRock, the world's largest asset manager, has significantly expanded its Ethereum exposure through the launch and scaling of two separate spot ETFs that serve different institutional and investor mandates. ETHA, which launched on Nasdaq in July 2024, holds direct ETH custody through Coinbase Prime and provides pure price exposure to Ethereum without active yield generation. By March 2026, when the firm debuted its second offering, ETHA had accumulated $6.5 billion in assets under management, establishing itself as the largest U.S. Ethereum ETF by this metric.
ETHB, launched on March 12, 2026, introduces a materially different risk-return profile by staking between 70% and 95% of its ETH holdings and distributing approximately 82% of gross staking rewards to investors on a monthly basis. This dual-product strategy allows BlackRock to address two distinct investor segments: those seeking pure spot exposure through ETHA and those willing to accept additional complexity and risk in exchange for yield through ETHB. Both funds charge identical 0.25% annual sponsor fees, standard for the spot crypto ETF category, and benchmark performance against the CME CF Ether-Dollar Reference Rate.
The introduction of ETHB carries a material distinction in risk profile. Unlike ETHA, which presents only market price risk, ETHB introduces slashing risk—the possibility that validators' stakes could be partially forfeited due to protocol violations or misconduct. Additionally, institutional investors must account for the tax treatment of staking rewards, which are generally classified as ordinary income under current IRS guidance rather than capital gains, creating a meaningful after-tax return differential.
Beyond these two Ethereum-focused products, BlackRock's broader digital asset strategy demonstrates significant institutional traction. The firm's BUIDL tokenized fund, launched on the Ethereum network in March 2024, surpassed $1 billion in assets under management by March 2025—a rapid adoption trajectory for a specialized tokenized asset product. BlackRock's iShares platform captured approximately 95% of all flows into digital asset ETPs during 2025, underscoring the firm's dominant market position in channeling institutional capital into cryptocurrency exposure vehicles.
