On September 27, 2025, REX Shares and Osprey Funds launched the REX-Osprey ETH Staking ETF (ESK) on the Cboe exchange, marking the first spot Ethereum ETF in the United States that incorporates staking rewards. This product allows shareholders to receive a portion of the rewards generated by the ETF’s staked Ethereum assets.
The ETF is structured under the Investment Company Act of 1940, rather than the Securities Act of 1933, enabling a faster approval process compared to other crypto funds. ESK invests directly in Ethereum, while the trust’s structure permits staking, with rewards distributed to shareholders, creating a new passive income opportunity for investors.
This launch follows earlier filings for Ethereum and Solana-based ETFs with staking capabilities submitted in June 2025. The ESK fund joins three other crypto-focused ETFs by REX and Osprey already listed on Cboe, which are based on Solana, Dogecoin, and XRP.
Currently, the ETF manages $625,000 in assets under management (AUM), with 25,000 shares in circulation. Although Ethereum’s price remains below $4,000, the ETF represents a notable step in integrating traditional investment products with digital asset staking. Analysts suggest that while the immediate impact on ETH’s market price is modest, the introduction of staking ETFs may drive long-term institutional adoption of Ethereum.
For investors, the ESK ETF offers a regulated, U.S.-based vehicle to gain exposure to Ethereum while earning staking rewards—blending traditional investment structures with decentralized finance mechanisms.
