In a December 19 ruling, a U.S. court has taken up MEV practices again, granting a motion to amend and resubmit new evidence in the collective lawsuit against Pump.fun, Jito Labs, and the Solana Foundation.

According to the complaint, Pump.fun allegedly employed MEV technology to enable insiders to front-run upcoming token launches at favorable prices, fueling a price surge and using retail participants as exit liquidity.

The filing also accuses Solana Labs, Jito Labs, and related entities of facilitating the described activity within the MEV ecosystem, amplifying concerns about market integrity in crypto launches.

Market observers should monitor ongoing regulatory and litigation risk as the case unfolds, noting implications for token launches, platform governance, and crypto market structure.
