Analysts are increasingly optimistic about the approval of Solana (SOL) and XRP exchange-traded funds (ETFs), estimating a 95% chance of approval. This confidence is fueled by underestimated investor demand and recent updates to Solana ETF filings by issuers such as Grayscale, VanEck, and Franklin Templeton. ETF analyst Nate Geraci noted similarities between current skepticism and the initial reception of Bitcoin and Ethereum ETFs, which eventually experienced strong demand. Regulatory decisions on these ETFs are expected in October, with Solana rulings anticipated around October 16 and XRP between October 18 and 23. However, the SEC's final decision remains uncertain.
