SEC Extends Review Period for Grayscale’s Solana, Litecoin, and Ethereum ETF Proposals

The U.S. Securities and Exchange Commission (SEC) has extended the review period for several of Grayscale Investments’ proposed spot cryptocurrency exchange-traded funds (ETFs), including those tied to Solana (SOL), Litecoin (LTC), and Ethereum (ETH). The decision, announced on May 13, 2025, comes as the Commission seeks more time to evaluate the filings under its investor protection and market integrity standards. The delays affect Grayscale’s efforts to list spot Solana and Litecoin ETFs on the NYSE Arca exchange. These proposed products aim to provide traditional investors with regulated exposure to the underlying digital assets without requiring direct token custody. However, the SEC has not provided a definitive timeline for approval or rejection, emphasizing its responsibility to thoroughly review novel digital asset products that could have broad implications for market participants. In its public notice, the SEC stated that “the Commission finds it appropriate to designate a longer period within which to take action on the proposed rule change so that it has sufficient time to consider the proposed rule change and the issues raised therein.” The review period extension aligns with the SEC’s historically cautious stance on crypto-linked financial instruments. While the agency approved 11 spot Bitcoin ETFs in January 2025—a move seen as a major milestone in legitimizing crypto assets in traditional finance—it has continued to treat newer altcoin products with greater scrutiny. The decision to delay reflects concerns over market manipulation risks, custody protocols, liquidity, and overall investor protection. Ethereum staking proposal under extended review In a separate but related action, the SEC also extended its review of Grayscale’s proposal to introduce staking into its Ethereum Trust. The proposed amendment, submitted by NYSE Arca on February 14, 2025, would enable the fund to participate in Ethereum’s proof-of-stake mechanism while maintaining existing custodial safeguards. Initially expected to be decided earlier this year, the Commission has now pushed the deadline to June 1, 2025, with a final decision due by the end of October. The SEC’s hesitancy reflects ongoing regulatory uncertainty around staking services, particularly whether they should be considered securities or yield-bearing instruments requiring additional oversight. Legal experts note that the SEC’s approach to staking proposals could set a precedent for future products incorporating similar yield-generating components. “Staking within a fund vehicle presents unique regulatory questions that the SEC has yet to fully resolve,” said Angela Morris, a financial regulatory analyst at Stratwell Advisory. “This decision could impact the structure of many future ETFs.” Market outlook remains optimistic despite delay Despite the delays, crypto market participants remain optimistic about the eventual approval of these ETFs. Prediction platform Polymarket currently forecasts an 82% chance of approval for the Solana ETF and an 80% chance for Litecoin by December 31, 2025. Market watchers view the extensions as procedural rather than indicative of rejection. Grayscale has reiterated its commitment to engaging constructively with regulators. In a public statement, the firm emphasized its role in expanding access to digital assets through transparent and compliant investment vehicles. “We remain confident in the merits of our proposals and continue to advocate for fair access to innovative financial products,” the company said. The SEC’s ongoing extensions suggest it is not dismissing these proposals outright but rather seeking additional public input and detailed analysis. This regulatory pacing reflects a broader shift toward transparency, driven by evolving leadership at the Commission and increased institutional demand for exposure to cryptocurrencies within a regulated framework. As key deadlines approach, stakeholders across traditional and digital finance will be watching closely for signs of regulatory clarity or further procedural pauses that could shape the future of crypto investing in the U.S.
