U.S. Judge Lets Pump.fun and Solana Class Action Add New Claims After Fresh Evidence
On December 15, 2025, a New York federal judge allowed plaintiffs in the class action against Pump.fun and Solana to file a second amended complaint based on newly submitted evidence. The suit targets investors who bought tokens launched on Pump.fun from March 2024 and alleges an unfair market structure, securities law violations, RICO violations, and unjust enrichment. Plaintiffs say thousands of chat messages from a reestablished confidential source link individuals associated with Pump.fun, Solana Labs, Jito Labs, and others, and the court found the proposed amendments sufficient to move forward.
