Pump.fun MEV Whistleblower — 5,000 Internal Chat Leak (2026)
Auto-generated score, not yet verified against the scoring model. Under review — treat as indicative, not a verdict.
Summary
Beginning in September 2025, an anonymous confidential informant supplied plaintiffs' counsel in a federal class-action suit with two batches of internal Pump.fun chat logs totaling approximately 15,000 messages — the first batch numbering roughly 5,000. The messages were incorporated into a Second Amended Consolidated Complaint filed January 7, 2026 in Aguilar v. Baton Corporation Ltd. (S.D.N.Y. 1:25-cv-00880-CM), which accuses Pump.fun's founders of orchestrating a RICO 'Pump Enterprise' that allegedly extracted between $4 billion and $5.5 billion from retail traders through MEV-enabled front-running and misleading marketing. As of August 31, 2026, a federal judge dismissed securities and Solana-related claims but allowed RICO and unlicensed money-transmission allegations against Baton Corporation and three named founders to proceed.
