The First Ethereum-ETF with Staking Launched in the US by REX Shares and Osprey Funds

On September 25, 2025, REX Shares and Osprey Funds announced the launch of a new investment product on the Cboe exchange — the REX-Osprey ETH + Staking ETF (ESK). This is the first Ethereum-based fund in the US that provides the possibility of asset staking.

The companies filed applications for the launch of such products back in June 2025. The key feature is registration under the Investment Company Act of 1940, rather than the Securities Act of 1933, which allowed the fund to be classified as a C Corporation and avoid lengthy regulatory review.

ESK invests directly in Ethereum and also provides for the use of purchased coins for staking. Staking rewards are distributed among the fund’s shareholders. According to Cboe’s website, the assets under management amount to $625,000, with 25,000 shares in circulation.

For REX Shares and Osprey Funds, this is already the fourth cryptocurrency ETF on Cboe. Previously, the companies launched funds based on Solana, Dogecoin, and XRP.

Despite the launch, no significant price effect for Ethereum has been recorded. According to Binance, ETH remains below the $4000 level, although the asset showed a slight increase on the daily chart.
