The lawsuit against Pump.fun has broadened to encompass Solana Labs and Jito Labs, as investors react to the volatile meme coin market. The amended legal complaint, due by January 7, 2026, accuses these entities of operating an unregistered securities platform and engaging in money laundering. The case includes over 15,000 internal communications as evidence. Since January 2025, Pump.fun's trading volume has plummeted by over 80%, and its PUMP token has depreciated by 78% from its peak value. The legal developments are drawing attention to altcoins as market dynamics shift under mounting legal scrutiny.
