The U.S. Securities and Exchange Commission (SEC) faces a series of decision deadlines in October for several altcoin ETFs, including those for Solana, XRP, Litecoin, and Dogecoin. Approvals could pave the way for increased institutional investment in these cryptocurrencies, potentially enhancing market liquidity. Major financial firms such as Grayscale, VanEck, 21Shares, and Canary Capital are actively seeking to convert existing funds and launch new ETF listings. Analysts anticipate a continuous stream of altcoin ETF decisions extending into mid-2025, which could significantly boost institutional exposure to these digital assets. The potential approvals are seen as a critical step in broadening investor access and reshaping the cryptocurrency market landscape.
