Solana's meme coin market experienced significant whale activity in September 2025, with major buying observed across several tokens. TRUMP led the market with over $529 million in buy volume, followed by FATCOIN at $248 million and TROLL at $148 million. Newer tokens such as USELESS and BONK also attracted strong inflows, while legacy coins like POPCAT and PENGU regained prominence. Whale wallets displayed diverse strategies, with some focusing on accumulating well-known tokens and others engaging in isolated, high-value trades. This activity underscores a polarized market, where trading is concentrated among a few large holders in some instances, while more distributed in others.
