- REX-Osprey ETF debuts with impressive $20M volume.
- First U.S.-listed ETF offering Solana staking rewards.

In a notable cryptocurrency market development, the REX-Osprey Solana + Staking ETF commenced trading on July 2, 2025. The fund is a collaboration between REX Shares and Osprey Funds, debuting in the U.S. financial markets.
Launched by REX Shares and Osprey Funds, this ETF represents a major entry into U.S. markets, reflecting increased mainstream acceptance of cryptocurrency-based investing.
The REX-Osprey Solana + Staking ETF is now operational, marking a significant milestone in the U.S. for digital asset investment vehicles. REX Shares and Osprey Funds have combined their expertise to offer this ETF, which includes spot Solana (SOL) and direct staking rewards. The ETF’s first day of trading saw a remarkable $20 million in volume, placing it in the top 1% of new launches by trading volume.
The ETF holds directly staked Solana along with other products, like JitoSOL, facilitating rewards at an annual rate of 7.3%. These benefits are passed directly to investors without retention by the managing companies. The CME CF Solana-Dollar Reference Rate is used for pricing, partnering with established crypto index providers.
“SSK is the first ETF to deliver spot SOL exposure alongside direct, on-chain staking rewards in a regulated investment vehicle.” — REX Shares
This launch could potentially increase demand for Solana-related assets, spurring liquidity on Solana-based protocols. Notably, the ETF is positioned to attract institutional and sophisticated retail investors, leveraging its regulated status to offer protocol-native yield in the U.S.
Historically, this ETF aligns with market-adaptive crypto products, illustrating how new financial tools can enhance investor accessibility to digital asset markets. This innovation recalls the impacts of previous Bitcoin spot ETFs, though the REX-Osprey offering uniquely integrates staking yields in a regulated package.
The debut of a product like the SSK ETF emphasizes the financial industry’s shifting landscape toward integrating cryptocurrency investment opportunities. As regulatory frameworks continue adapting, such initiatives indicate how blockchain and crypto assets may be woven more directly into traditional finance architectures.
