Keith Gill, known as "Roaring Kitty" on social media, is at the center of a class-action lawsuit alleging he manipulated GameStop's stock price through his influential posts.

The lawsuit, filed on June 28 in the Eastern District of New York, accuses Gill of participating in a "pump-and-dump" scheme by secretly buying GameStop call options before his May 12 meme post, which sparked a 74% stock surge the next day.

On June 2, Gill revealed his massive GameStop stake, leading to another 70% premarket price jump. The complaint claims Gill failed to disclose his intent to sell the options, misleading followers and causing investor losses. However, legal experts are skeptical about the lawsuit's viability, citing issues like Gill's options expiration and lack of fiduciary duty to disclose.

The case highlights the ongoing debate around social media influencers' impact on stock markets and the challenges of regulating such interactions.
