The debut of the first Solana call ETF in U.S. history—$SSK—marked a pivotal moment for the crypto investment landscape. Launched on July 2 by issuer REX Shares, the ETF recorded a robust $33 million in trading volume on its first day, with $12 million in net inflows. Notably, $8 million of that volume occurred within the first 20 minutes of trading, surpassing $20 million within just two hours. According to Bloomberg ETF analyst Eric Balchunas, this performance places $SSK among the top 1% of all ETF launches by initial activity.

Strong Performance Despite Structural Limitations
While $SSK’s debut volume doesn’t match the eye-popping numbers seen during the launches of Bitcoin and Ethereum spot ETFs earlier in 2025, context is critical. The Bitcoin and Ethereum products entered the market with support from multiple major issuers—Ethereum’s spot ETF, for example, launched with eight different providers, enabling broader distribution and immediate liquidity.
In contrast, $SSK is backed by only two relatively niche players in the ETF space: REX Shares and Osprey Funds. Despite their smaller market footprint, the combined effort generated more initial volume than previous Solana and XRP futures ETFs. This outperformance signals strong underlying institutional interest in Solana (SOL) exposure and suggests even greater potential when larger financial institutions enter the arena.
The fact that a limited-release product can achieve such traction underscores a growing appetite for regulated Solana investment vehicles. If firms like Fidelity or VanEck were to launch their own versions, the influx of capital could easily multiply current volumes.
Hybrid Structure Enabled Faster Regulatory Approval
One of the key reasons $SSK was approved ahead of pure spot ETFs lies in its unique composition. The fund consists of 55.02% direct Solana (SOL) holdings and 44.95% exposure to the 21Shares Solana Staking ETP, creating a hybrid structure that blends spot and staking-linked assets.
This innovative design allowed regulators to greenlight the product without fully endorsing a traditional spot ETF—a category still under review by the SEC. By incorporating an existing European-listed staking ETP, the structure sidestepped some of the regulatory hurdles typically associated with pure spot applications.
Moreover, this blend introduces staking yield potential into the ETF framework, differentiating it from conventional products and offering investors both capital appreciation and passive income opportunities—a compelling value proposition in today’s yield-sensitive markets.

Growing Pipeline Points to Strong Spot ETF Demand
Despite $SSK’s early success, it remains a partial solution. True spot ETFs—offering direct ownership of SOL without reliance on derivatives or foreign instruments—are still pending approval. However, there are currently nine major applications under review, filed by industry titans including:
- Fidelity
- Franklin Templeton
- VanEck
- ARK Invest
- BlackRock
These firms collectively manage trillions in assets and have vast retail and institutional distribution networks. Their interest in a Solana spot ETF is not speculative—it reflects serious conviction in SOL’s long-term viability as a digital asset.
Given that a small issuer like REX Shares achieved $33 million in day-one volume, projections for a Fidelity- or BlackRock-led launch are highly optimistic. Historical data from Bitcoin and Ethereum ETF rollouts suggests that initial trading volumes could reach hundreds of millions within days of approval.
CME Futures Activity Confirms Institutional Momentum
The launch of $SSK coincided with a record surge in Solana futures trading on the Chicago Mercantile Exchange (CME). Open interest for Solana futures spiked to **$167 million**, reflecting heightened institutional demand for regulated derivatives exposure.
This dual momentum—both in ETFs and futures—signals that traditional finance is increasingly embracing Solana as a credible asset class. The combination of growing on-chain activity, improving network stability, and expanding DeFi and NFT ecosystems has bolstered confidence among professional investors.
CME’s role as a trusted derivatives platform adds another layer of legitimacy, making it easier for pension funds, hedge funds, and asset managers to gain exposure without holding crypto directly.
What This Means for Solana’s Future
The success of $SSK is more than just a one-day headline—it's a leading indicator. It demonstrates that:
- There is proven demand for regulated Solana investment products.
- Hybrid structures can serve as regulatory stepping stones to full spot approval.
- Institutional players are actively preparing for broader market access.
As more issuers await SEC decisions, the pressure for a pure Solana spot ETF approval intensifies. With Bitcoin and Ethereum already cleared, the argument for Solana’s inclusion grows stronger—especially given its performance, scalability, and developer momentum.
Frequently Asked Questions (FAQ)
