The financial markets welcomed a groundbreaking addition this week: the first U.S. exchange-traded fund (ETF) offering direct exposure to Solana (SOL) and on-chain staking rewards. The REX-Osprey Solana + Staking ETF (SSK) debuted on the Cboe exchange on July 2, 2025, attracting significant investor interest with $33 million in trading volume** and **$12 million in inflows on its first day.
Key Highlights of the SSK ETF
- Structure: Classified under the Investment Company Act of 1940, ensuring robust investor protections and custody standards.
- Custodian: Anchorage Digital, the only federally chartered crypto bank authorized for custody and staking, serves as the ETF’s custodian.
Asset Allocation:
- 80% allocated to SOL, with at least half staked via institutional validators like Galaxy and Figment.
- Remaining holdings include liquid staking tokens (e.g., JitoSOL) and other SOL-linked exchange-traded products.
- Pricing Model: Tracks the CME CF Solana-Dollar Reference Rate, ensuring accurate market price alignment.
How the ETF Stands Out
👉 Why this Solana ETF is a game-changer for crypto investors
Unlike futures-based ETFs, SSK offers spot price exposure and monthly staking rewards distributed as cash payouts—a first for U.S. investors seeking passive income from crypto. Its launch outperformed early trading of Solana and XRP futures ETFs but trailed the historic volumes of spot Bitcoin and Ethereum ETFs.
Regulatory Journey
The ETF’s approval followed months of scrutiny from the U.S. Securities and Exchange Commission (SEC), which initially raised concerns about fund classification and staking mechanisms. By late June 2025, the SEC’s silence effectively greenlit the product, paving the way for similar offerings.
Market Implications
With nine other Solana ETF applications pending and growing interest in staking-based crypto products, SSK’s success could shape the future of U.S. cryptocurrency ETFs. Analysts speculate it may accelerate demand for yield-generating investment vehicles in the digital asset space.
FAQ Section
Q: How does staking work within the SSK ETF?
A: The fund stakes SOL through institutional validators, converting rewards into monthly cash distributions for investors.
Q: What’s the advantage of a spot Solana ETF over futures?
A: Spot ETFs track SOL’s live market price more closely, avoiding the roll costs associated with futures contracts.
Q: Are there risks to staking via an ETF?
A: While staking carries slashing risks, SSK mitigates these by using federally regulated custodians and professional validators.
Q: Will more staking ETFs follow?
A: Likely. The SEC’s tacit approval of SSK sets a precedent for similar products, especially with rising demand for crypto passive income.
