On September 25, 2025, the first spot ETF based on Ethereum with staking was launched in the US on the Cboe exchange — the REX-Osprey ETH Staking ETF (ESK), created in collaboration between REX Shares and Osprey Funds. This new financial product offers investors the opportunity not only to own shares that reflect the value of Ethereum but also to earn a portion of rewards through staking the trust’s assets.

Features of ESK and Its Differences from Other ETFs
The REX-Osprey ETH Staking ETF has become the first fund in the US that allows purchased Ethereum to be used for staking within the trust. Shareholders of ESK receive additional income in the form of a share of the rewards for locking the assets. The current assets under management for ESK amount to $625,000, with 25,000 shares in circulation.
In early June 2025, REX Shares and Osprey Funds submitted applications to launch staking ETFs based on Ethereum and Solana. Both products are registered under The Investment Company Act of 1940, which distinguishes them from the vast majority of other crypto funds that fall under the Securities Act of 1933 and are classified as C Corporations. This structure has allowed the companies to avoid a lengthy approval process for their applications.
Market Dynamics and Future Prospects
According to data from the official Cboe website, the REX-Osprey ETH Staking ETF has become the fourth cryptocurrency fund from these companies on the exchange, following the launch of products based on Solana, Dogecoin, and XRP. ESK directly invests in Ethereum and allows the use of assets for staking, distributing rewards among the fund’s shareholders.
“Shareholders are entitled to a portion of the rewards for locking the assets in the trust.”
Despite the positive news about the launch of the first spot Ethereum ETF with staking in the US, the price of Ethereum remains below the $4000 mark. Analysts note that the launch of ESK has not significantly impacted the market value of ETH. 
It is worth noting that other ETF issuers are currently awaiting a decision from the US Securities and Exchange Commission (SEC) regarding the possibility of adding staking to existing spot ETFs on Ethereum. The regulator has not yet made a final decision, although it has already published clarifications stating that cryptocurrency staking does not contradict current securities legislation.
