Another first was achieved in the USA yesterday, and the first staking ETF in the USA was approved and opened for trading. The US’s first Solana (SOL) Staking ETF (SSK), launched by REX-Osprey, attracted a lot of attention on its first day. The REX-Osprey Solana + Staking ETF, the first approved spot staking crypto ETF in the U.S., saw $33 million in first-day trading volume, Bloomberg Senior ETF Analyst Eric Balchunas said. Bloomberg analyst James Seyffart also noted the success of the Solana ETF and said, “The first Solana Staking ETF in the US has been launched. SSK recorded approximately $8 million in trading volume in just 20 minutes after its launch.” The ETF also achieved $1 million in assets under management. The Solana ETF's performance has outpaced the Solana and XRP futures ETFs and the average ETF outflow. However, it still fell short of spot Bitcoin (BTC) and Ethereum (ETH) ETFs. Admitted under stricter oversight and regulations under the Securities Act of 1940, the ETF chose Anchorage as its custodian. $SSK ended day with $33m in volume. Again, blows away the Solana futures ETF and XRP futures ETFs (or the avg ETF launch) but it is much lower than the Bitcoin and Ether spot ETFs. pic.twitter.com/t6LkQwDXLc — Eric Balchunas (@EricBalchunas) July 2, 2025 *This is not investment advice.
