More than 130 altcoin ETFs have been filed with the U.S. Securities and Exchange Commission (SEC), with over 30 set to launch in November and December 2025. This surge in filings follows the success of Bitcoin and Ethereum spot ETFs and includes products focused on Solana, XRP, Dogecoin, and Chainlink. Leading firms such as Grayscale, VanEck, and Bitwise are spearheading these filings. Analyst James Seyffart has been closely monitoring the approval prospects of these funds, which are anticipated to boost institutional interest and liquidity in the altcoin market.
