Multiple institutions have submitted updated S-1 filings, planning to launch Solana spot exchange-traded funds (ETFs) on Friday, indicating that the U.S. Securities and Exchange Commission (SEC) may be closer to approving these products. The institutions submitting updated filings include Franklin Templeton, Galaxy Digital, VanEck, and Fidelity, with Fidelity filing the S-1 for a Solana spot trading product for the first time. The SEC has requested issuers to update explanations regarding physical redemption and staking methods, with VanEck including staking details in its updated filing. The SEC has approved Bitcoin and Ethereum spot ETFs but remains cautious about other token products, recently postponing decisions on products such as Avalanche, Dogecoin, and Hedera, and seeking public comments. Experts believe that under a more favorable SEC administration, the chances of Solana approval are higher, especially after the Chicago Mercantile Exchange (CME) listed SOL futures. Some issuers call on the SEC to follow the "first-come, first-served" review principle.
