Class Action Lawsuit Against Pump.fun and Solana Gets Green Light

December 17, 2025

Judge Colleen McMahon of the U.S. District Court for the Southern District of New York has approved the plaintiffs’ request to file a second amended complaint in their lawsuit against token launch platform Pump.fun and blockchain network Solana, following the submission of new evidence supporting their case.

Key Points

  • A New York federal judge approved a second amended complaint in the Pump.fun and Solana class action.
  • Plaintiffs say new evidence from a confidential source supports claims of unfair market structure.
  • The case could shape how courts view accountability in crypto platforms.

The lawsuit covers individuals who purchased tokens launched on Pump.fun from March 2024 onward and experienced financial losses. While Pump.fun and Solana sought to dismiss the motion on legal grounds, the court denied their request, allowing plaintiffs additional time to include new evidence reportedly obtained from a confidential informant.

Recent court documents indicate that the plaintiffs have been permitted to file an amended complaint, with allegations spanning violations of the Securities Act, RICO violations, and claims of unjust enrichment. “What appeared to be a fair, automated marketplace was, Plaintiffs say, structurally tilted to extract value from ordinary users while rewarding those with privileged access to Solana’s infrastructure and Jito Lab’s transaction ordering tools,” the lawsuit claimed.

Furthermore, the plaintiffs claim they obtained new information from a source who had previously gone missing but later reestablished contact, allegedly providing thousands of chat messages. After reviewing the material, the court found the proposed amendments adequate to move forward and either denied or deferred related defense motions.

The chat records are expected to be submitted as evidence and are said to reference individuals connected to Pump.fun, Solana Labs, Jito Labs, and other third parties. While the defendants argued the request should be rejected because a proposed amended complaint was not attached, the court disagreed and granted permission to file a second amended complaint. The plaintiffs also sought adjustments to the case schedule to allow time to review the new material and integrate it into the forthcoming filing.
