REX-Osprey’s Solana staking ETF (SSK) has surpassed $100 million in assets under management less than a month after launch. It is the first U.S.-listed ETF to combine spot SOL holdings with onchain staking rewards, enabled by its structure under the Investment Company Act of 1940. The fund appeals to institutional investors and financial advisers seeking recurring yield. REX-Osprey is also planning similar ETFs for XRP, DOGE, and ETH. As global interest rates plateau and U.S. regulations clarify, staking is becoming an increasingly attractive strategy for institutional capital.
