Judge Lets Pump.fun Class Action Add Over 5,000 Chat Logs on MEV

On 19 December 2025, a U.S. judge allowed plaintiffs to amend and refile a class-action complaint against Pump.fun, Solana Labs, the Solana Foundation, and Jito Labs. The motion cites over 5,000 internal chat logs from a confidential informant submitted in September, tied to maximal extractable value practices. The case, first filed in July, may influence how courts handle MEV-related disputes.
