The launch of the REX-Osprey Solana Staking ETF marks a pivotal development in the convergence of traditional finance and digital assets. On its debut day, the fund attracted $12 million in inflows and achieved $33 million in trading volume—early but compelling evidence of growing institutional appetite for staking-enabled crypto investment products.
Listed on the Cboe BZX Exchange under the ticker SSK, this exchange-traded fund (ETF) stands out as the first staking-enabled Solana ETF based in the United States. By offering direct exposure to spot Solana (SOL) while allowing investors to earn staking rewards, it bridges a critical gap between passive income strategies and institutional-grade crypto access.

A Strong Start Amid Competitive Landscape
While still modest compared to the record-breaking $4.6 billion combined first-day volume of Bitcoin and Ether spot ETFs in January 2024, the performance of the Solana staking ETF surpassed initial trading activity seen with Solana and XRP futures ETFs. According to Bloomberg ETF analyst Eric Balchunas, the opening day demonstrated solid market engagement.
James Seyffart, another prominent Bloomberg analyst, described the launch as a “healthy start,” highlighting that the fund recorded $8 million in volume within just the first 20 minutes of trading. This rapid uptake suggests that institutional and retail investors alike are eager for regulated, income-generating crypto products.
Nathan McCauley, co-founder of Anchorage Digital and a key custody partner for the ETF, called the launch “a watershed moment for digital assets” and emphasized its role in expanding full ecosystem access for mainstream investors.
Regulatory Innovation Behind the Scenes
One of the most significant aspects of the REX-Osprey Solana Staking ETF is how it navigated regulatory hurdles. Unlike other proposed spot Solana ETFs still awaiting SEC approval, this fund bypassed traditional clearance processes by structuring itself to invest at least 40% of its assets in non-U.S. exchange-traded products (ETPs). This approach allows it to sidestep a standard 19b-4 filing with the SEC under the Investment Company Act of 1940.
While some industry observers have questioned whether this makes it a “true” domestic Solana ETF, the structure has opened a new regulatory pathway for crypto-based financial products. Nate Geraci, president of The ETF Store, referred to the move as a “regulatory end-around”—a creative workaround that could inspire similar innovations across the altcoin ETF space.
Despite not being a fully domestic spot ETF, its approval and strong market reception signal increasing regulatory tolerance and institutional readiness for advanced crypto investment vehicles.
Market Reaction and Price Impact
Although Solana’s price did not surge dramatically post-launch, SOL saw a steady 3.6% increase within 24 hours, trading around $155.58 at publication time. Over the prior week, Solana had gained 5%, reflecting broader market optimism. However, it remains down 48% from its all-time high reached in January 2025.
The more telling indicator of institutional momentum came from derivatives markets. Open interest in CME Solana futures spiked to $167 million following the ETF’s debut—a clear sign of rising institutional participation and hedging activity.
This surge underscores that sophisticated investors are not only watching but actively positioning themselves around Solana’s expanding financial infrastructure.
Path Forward: Spot ETFs on the Horizon?
The success of the REX-Osprey fund may pave the way for broader acceptance of spot Solana ETFs in the near future. Analysts James Seyffart and Eric Balchunas estimate a 95% probability that spot ETFs for Solana, XRP, and Litecoin will be approved by U.S. regulators within 2025.
This projection aligns with recent regulatory movements, including the SEC’s approval of Grayscale’s conversion of its Digital Large-Cap Fund—an ETF that includes Solana among its top five holdings by market capitalization.
As staking-enabled and altcoin-focused ETFs gain traction, they could fundamentally reshape how traditional investors access digital assets—moving beyond speculation into structured, yield-generating investment strategies.

Frequently Asked Questions (FAQ)
Q: What is the REX-Osprey Solana Staking ETF?
A: It’s the first U.S.-based exchange-traded fund that provides exposure to Solana (SOL) while enabling investors to earn staking rewards. Listed under ticker SSK, it combines traditional investment structures with blockchain-native yield mechanisms.
Q: How does it differ from a spot Solana ETF?
A: Unlike a pure spot ETF, which directly holds SOL and tracks its price, the REX-Osprey fund invests partially in non-U.S. ETPs to comply with regulations. This structure allows it to offer staking benefits while bypassing certain SEC requirements.
Q: Why is staking important in an ETF?
A: Staking allows token holders to earn passive income by supporting network security. Including staking in an ETF gives investors yield on top of price appreciation—making crypto investments more attractive to conservative and institutional players.
Q: Did Solana’s price jump after the ETF launch?
A: Not dramatically. SOL rose 3.6% within 24 hours and was trading near $155.58. The bigger impact was seen in futures markets, where CME open interest hit $167 million, indicating strong institutional positioning.
Q: Is this ETF fully approved by the SEC?
A: It operates under a regulatory workaround by investing in offshore ETPs, avoiding direct SEC approval for a traditional 19b-4 listing. While not a conventional spot ETF, it is legally compliant and available for trading.
Q: Could this lead to a spot Solana ETF approval?
A: Yes. Analysts believe this launch demonstrates demand and regulatory feasibility, increasing the likelihood of formal spot ETF approvals for Solana and other altcoins by late 2025.
