A new financial product designed to open investment channels into digital assets began trading in the United States on Wednesday. The REX-Osprey Solana + Staking ETF (ticker: SSK) is the first US exchange-traded fund to offer direct exposure to Solana cryptocurrency, debuting on the Cboe BZX Exchange. This launch signals another step toward mainstream acceptance for crypto assets and has sparked discussions about the future of smaller cryptocurrency ETFs.
Unlike the widely followed spot Bitcoin and Ethereum ETFs, SSK introduces traditional investment platforms to Solana, a comparatively niche asset. Solana is currently the sixth-largest cryptocurrency by market cap and is often viewed as a strong competitor to Ethereum. Through SSK, US investors can gain indirect exposure to Solana without directly holding the cryptocurrency, bypassing complexities like wallet management and crypto exchange accounts.
The ETF is a joint offering from REX Financial and Osprey Funds. Greg King, Founder and CEO of REX, noted in an interview that initial investors are expected to be primarily retail participants, with gradual expansion to institutional investors and registered investment advisors over time.
According to FactSet data, SSK rose 43 cents on its first trading day, closing at $25.90—a gain of approximately 1.69%. On the same day, Solana’s price increased by 4.2% to $153.81, though it remains nearly 48% below its all-time high of $294.43, set in January of this year.
ETF senior analyst Eric Balchunas reported on social media platform X that, as of 11:44 AM ET on Wednesday, SSK had already reached $20 million in trading volume, placing it in the top 1% for first-day trading volumes among new ETFs.
It’s important to note that SSK is not a "pure" spot Solana ETF. According to its prospectus, roughly 40% of the fund’s assets will be invested in other Solana ETFs, primarily issued outside the US, with the remainder invested directly in Solana. Additionally, the fund intends to engage in staking—locking up a portion of its holdings in the blockchain network to earn rewards—and will pass those earnings on to investors. Based on current rates from major staking providers, Solana staking offers an estimated annual yield of around 7.3%.
This also makes SSK the first crypto ETF in the market that incorporates staking. By comparison, even though Ethereum supports staking, the spot ETH ETFs launched last year excluded staking functionality due to regulatory considerations.
SSK is structured differently from the Bitcoin and Ethereum ETFs launched last year. It operates under the Investment Company Act of 1940, while most mainstream crypto ETFs are based on the Securities Act of 1933. The 1940 Act imposes stricter operational requirements on investment companies, resulting in higher management costs. SSK carries a management fee of 0.75%, plus a 0.65% expense ratio, bringing the total annual cost to 1.4%—significantly higher than most Bitcoin ETFs, which typically charge around 0.25% or less.
In response, King argued that compared to the Grayscale Bitcoin Trust ETF’s 1.5% fee, and considering that many offshore Solana products retain a portion of staking rewards, SSK’s fee structure represents a "fair trade" for investors.
The launch of SSK has been facilitated by a more favorable political and regulatory environment. The Trump administration is perceived as supportive of cryptocurrency, having not only helped establish Bitcoin reserves but also launched crypto meme coins endorsed by the former president and his wife, Melania.
In 2024, the US Securities and Exchange Commission (SEC), under the Biden administration, approved spot Bitcoin and Ethereum ETFs but had previously rejected a Solana ETF citing market manipulation and insufficient investor protection. However, analysts note that regulatory attitudes are gradually softening, and expect ETFs for other mid- and small-cap cryptocurrencies—including XRP, Cardano, and Litecoin—to gain approval within the year.
Currently, nine major financial institutions—including Fidelity, Franklin Templeton, and VanEck—have submitted applications for Solana ETFs and are awaiting SEC review. Analysts point out that some investors may prefer ETFs from these established firms due to their long-term credibility, asset management experience, and potentially lower fee structures.
Despite SSK’s strong debut, questions remain about the overall demand for Solana and other small-cap crypto ETFs. For example, since their launch in January 2024, Bitcoin ETFs have accumulated $131.6 billion in assets under management, while Ethereum ETFs, launched in July, have attracted only $9.9 billion. Net inflows into Bitcoin ETFs reached $38.6 billion—nearly ten times that of Ethereum ETFs.
Industry experts suggest that one reason for this disparity is that Bitcoin’s role as "digital gold" is more clearly defined, while Ethereum and Solana are seen as smart contract platforms whose use cases may be less intuitive to the average investor.
Alex Thorn, Head of Research at Galaxy Digital, noted that ETFs like SSK will hold value particularly if there are no other convenient, legal channels for gaining exposure to these crypto assets. Otherwise, some investors may still prefer buying cryptocurrencies directly through exchanges like Coinbase.
