The Securities and Exchange Commission has published Amendment No. 2 to a proposed rule change that would allow NYSE Arca to list and trade shares of the Grayscale Solana Trust under commodity-based trust shares regulations. This latest filing, dated August 14, 2025, represents a significant step forward in the highly anticipated approval process for a spot Solana exchange-traded fund.
The amendment filing comes as part of an intensifying competition between major financial firms to bring the first Solana ETF to market. Grayscale’s Solana Trust has been under SEC review since January 2025, with the regulator repeatedly extending deadlines as it evaluates the application alongside competing proposals from other asset managers.
Market observers have been closely watching the regulatory progress of cryptocurrency ETFs beyond Bitcoin and Ethereum, viewing Solana as the next major digital asset likely to receive institutional investment vehicle approval. The latest NYSE Arca filing indicates that preparations for potential listing are advancing, even as the SEC continues its deliberative process.

Industry analysts suggest that the filing of multiple amendments demonstrates serious intent from both Grayscale and the exchange to address regulatory concerns. The SEC has historically required extensive documentation and multiple revisions before approving novel cryptocurrency investment products, making amendment filings a normal part of the approval process.
According to recent reports, Bloomberg analysts have assigned a 95% approval chance to Solana and XRP ETFs, indicating growing confidence in the regulatory pathway for alternative cryptocurrency investment vehicles. This optimistic outlook reflects the SEC’s evolving stance on digital asset products following the successful launch of Bitcoin and Ethereum ETFs.
The competitive landscape has intensified with Invesco Galaxy submitting its own Solana ETF application, creating a direct rivalry with Grayscale’s offering. Both applications are currently under SEC review, with regulators now faced with evaluating competing proposals from reputable financial institutions.
Grayscale’s ETF Development Progress
Grayscale’s Solana Trust has been trading over-the-counter under the ticker symbol ‘GSOL’ while awaiting regulatory approval for exchange listing. The trust structure allows investors to gain exposure to Solana without directly holding the cryptocurrency, following the same model that Grayscale has successfully employed for Bitcoin and Ethereum products.
The S-1 registration statement filed in April 2025 outlined Grayscale’s intention to list shares on NYSE Arca following SEC effectiveness. The trust operates as a Delaware statutory trust issuing fractional undivided beneficial interest shares, providing a familiar investment vehicle structure for institutional and retail investors.
Key features of the Grayscale Solana Trust include:
- Continuous share issuance with indeterminate number of shares registered
- Pricing based on Solana market value and share trading prices
- Over-the-counter trading availability during approval process
- Planned NYSE Arca listing under ‘GSOL’ ticker symbol
The trust structure differs from a registered investment company, meaning it operates outside Investment Company Act regulations. This approach has allowed Grayscale to launch similar products while navigating the complex regulatory environment surrounding cryptocurrency investment vehicles.
Solana’s Institutional Investment Appeal
Solana has emerged as a leading smart contract platform, attracting significant developer activity and institutional interest due to its high-performance blockchain architecture. The network’s ability to process thousands of transactions per second at low costs has positioned it as a viable alternative to Ethereum for decentralized applications and financial services.
The potential approval of a Solana ETF would mark a milestone for the cryptocurrency’s institutional accessibility, validating SOL as an investable asset within traditional markets. Investment professionals have been seeking regulated exposure to Solana, particularly given its role in powering decentralized finance protocols and non-fungible token marketplaces.
Recent developments in the Solana ecosystem include growing adoption of its blockchain for various applications, from payments to gaming to decentralized exchanges. This expanding use case portfolio has strengthened the investment thesis for Solana-focused financial products, contributing to the push for ETF approval.
Regulatory Landscape and Market Implications
The SEC’s approach to cryptocurrency ETFs has evolved significantly since initially rejecting Bitcoin ETF applications years ago. The successful launch and operation of Bitcoin and Ethereum spot ETFs have established precedents that benefit subsequent cryptocurrency ETF applications, including those for Solana.
Regulatory concerns historically centered on price manipulation, market surveillance, and investor protection have been addressed through improved market structure and institutional participation. The maturation of cryptocurrency markets and enhanced regulatory frameworks have created more favorable conditions for alternative digital asset ETFs.
The October 10 deadline for the SEC’s decision on Grayscale’s Solana ETF application creates a specific timeline for market participants. However, regulators maintain the flexibility to extend deadlines or request additional information as part of their comprehensive review process.
Competition between multiple Solana ETF applications may actually accelerate the approval process, as regulators face pressure to provide clarity and establish consistent standards for similar products. The presence of applications from both Grayscale and Invesco Galaxy demonstrates significant institutional commitment to Solana investment vehicles.
The SEC filing represents procedural progress in the complex approval process, though final authorization remains subject to regulatory discretion and market conditions.

The filing of Amendment No. 2 for the Grayscale Solana Trust listing signals continued momentum toward potential ETF approval, which could catalyze broader institutional adoption of Solana and establish the framework for additional alternative cryptocurrency investment products. Market participants will closely monitor SEC communications and regulatory developments as the October deadline approaches, with successful approval potentially opening the door for a new wave of digital asset ETFs beyond the current Bitcoin and Ethereum offerings.
