The US financial market has taken another bold step toward embracing digital assets with the official launch of the first exchange-traded fund (ETF) dedicated to Solana (SOL), a high-performance blockchain platform. The REX-Osprey Solana + Staking ETF (SSK.US) began trading on the Cboe BZX Exchange, opening new investment pathways for traditional investors and signaling a pivotal moment in the mainstream adoption of cryptocurrencies.
This milestone positions Solana—currently the sixth-largest cryptocurrency by market capitalization—as a growing contender in the decentralized application ecosystem, often viewed as a strong competitor to Ethereum. Unlike direct crypto ownership, which requires managing private keys and navigating volatile exchanges, SSK allows investors to gain exposure to Solana through a regulated, familiar vehicle: an ETF.

A New Chapter for Alternative Asset Investment
SSK is not just another crypto fund—it’s a strategic evolution in how digital assets are accessed. Developed jointly by REX Financial and Osprey Funds, this ETF enables both retail and institutional investors to participate in Solana’s growth without the technical complexities of self-custody or exchange-based trading.
Greg King, CEO and founder of REX, emphasized that while early interest is expected to come from retail investors, the long-term vision includes broader adoption by registered financial advisors and institutional portfolios. This dual-target approach reflects growing confidence in crypto’s durability as an asset class.
On its debut day, SSK opened with strong momentum, rising 43 cents to close at $25.90—a 1.69% gain. Concurrently, Solana’s native token (SOL) surged 4.2% to $153.81, though still down nearly 48% from its all-time high of $294.43 set in January 2025. According to ETF expert Eric Balchunas, trading volume reached $20 million by midday, placing SSK among the top 1% of new ETF launches by first-day activity.
How SSK Differs from Bitcoin and Ethereum ETFs
While Bitcoin and Ethereum spot ETFs paved the way, SSK introduces several structural innovations:
- Hybrid Investment Model: Only about 60% of the fund directly holds Solana tokens. The remaining 40% is allocated to overseas-issued Solana ETFs, diversifying access channels and potentially mitigating custody risks.
- Staking Integration: For the first time in a US-listed crypto ETF, SSK incorporates staking—a process where tokens are locked into the blockchain network to validate transactions and earn rewards. With current Solana staking yields averaging around 7.3% annually, this feature enhances potential returns for shareholders.
- Regulatory Framework: Unlike most major crypto ETFs built under the 1933 Securities Act, SSK operates under the stricter 1940 Investment Company Act, which imposes more rigorous operational standards but increases investor protections.
However, these advantages come at a cost. The fund charges a 0.75% management fee, plus an estimated 0.65% in tax-related expenses, bringing total annual costs to 1.4%—significantly higher than Bitcoin ETFs, many of which operate below 0.25%. Still, Greg King defends the pricing, noting that compared to Grayscale’s Bitcoin Trust (which charges 1.5%) and offshore Solana products that retain staking rewards, SSK offers a fair value proposition.

Regulatory Shifts Pave the Way for Broader Crypto Access
The approval of SSK reflects a notable shift in the US regulatory landscape. While the Securities and Exchange Commission (SEC) previously rejected Solana ETF proposals under the Biden administration—citing concerns over market manipulation and investor protection—the current political climate appears more accommodating.
With growing bipartisan support for blockchain innovation, including pro-crypto stances from key political figures, analysts believe the door is now open for additional altcoin-based ETFs. Products linked to XRP, Cardano (ADA), Litecoin (LTC), and other mid-cap cryptocurrencies are widely expected to receive approval in the coming months.
Nine major financial institutions—including Fidelity, Franklin Templeton, and VanEck—have already filed applications for their own Solana ETFs. Should any be approved, they may challenge SSK’s first-mover advantage with stronger brand recognition, lower fees, and larger distribution networks.
Market Demand: Will Altcoin ETFs Catch Up?
Despite SSK’s promising debut, questions remain about sustained demand for non-Bitcoin crypto ETFs.
Since the launch of spot Bitcoin ETFs in early 2024, total assets have ballooned to $131.6 billion**, with net inflows reaching **$38.6 billion. In contrast, Ethereum ETFs—launched in July—have attracted only $9.9 billion in assets, highlighting a significant gap in investor appetite.
Experts attribute this disparity to perception and utility:
- Bitcoin is widely regarded as “digital gold”—a store of value with clear narrative appeal.
- Ethereum and Solana, while technologically advanced as smart contract platforms, face higher comprehension barriers among average investors due to their complex use cases in DeFi, NFTs, and Web3 infrastructure.
Alex Thorn, head of research at Galaxy Digital, cautions that ETFs like SSK must offer compelling advantages over direct purchase options such as Coinbase (COIN.US). If investors can easily buy SOL on regulated exchanges with lower fees and full control over staking rewards, the value proposition of an ETF narrows.
