A new milestone has arrived for crypto investors in traditional markets. REX-Osprey™, a joint venture between REX Shares and Osprey Funds, has launched the first U.S.-listed Ethereum ETF that incorporates staking rewards.
The new fund, named ESK – REX-Osprey ETH + Staking ETF, gives investors regulated exposure to spot Ethereum while also distributing monthly staking yields from Ethereum’s proof-of-stake network. Structured under the 1940 Act, the ETF aims to provide a cost-efficient and accessible way for U.S. investors to capture both ETH’s market performance and its staking income.
According to the companies, the fund will hold a mix of directly staked ETH and exchange-traded products that themselves stake Ethereum. All staking rewards will be passed through to investors in full, with neither REX nor Osprey retaining a share.
Greg King, CEO of REX Financial, said the product builds on the firm’s vision of mainstreaming crypto staking within the ETF model. “With ESK, we’re giving investors access to Ethereum plus staking rewards in the broadest U.S. ETF format,” he noted.
The launch follows the earlier success of SSK – REX-Osprey Solana + Staking ETF, introduced in July 2025. That fund was the first U.S. product to pair spot Solana exposure with staking distributions. SSK has already surpassed $300 million in assets under management and recently converted into a Regulated Investment Company (RIC) structure to enhance tax efficiency.
While the ESK fund offers a new pathway into Ethereum for traditional investors, the companies emphasized that it is not a direct investment in ETH and carries significant risks, including potential loss of principal.
Still, the debut of an Ethereum staking ETF under U.S. regulation underscores the growing convergence between digital assets and traditional financial products, and positions REX-Osprey as an early leader in the staking ETF market.
