Meta, YouTube Liable for Addiction; $3M Verdict

The verdict, delivered in March 2026 in the case of _K.G.M. v. Meta & YouTube_, determined that platform design features like infinite scrolling and autoplay were substantial factors in causing mental health harm.

This case is significant because it focused on defective product design rather than user-generated content, potentially circumventing Section 230 protections. The jury also found evidence of "malice or oppression," leading to a separate punitive damages phase.

This outcome establishes a precedent for future social media addiction lawsuits, influencing how claims against digital platforms are framed and evaluated, particularly regarding design choices and corporate responsibility for user well-being. The National Library of Medicine and Science News Today are cited for research linking prolonged social media use to anxiety/depression and behavioral conditioning.
