A California jury has ordered Meta Platforms and Google to pay $6 million in damages to a 20-year-old plaintiff after finding that design features on Instagram and YouTube contributed to harmful addiction patterns during her childhood, marking a significant development in U.S. litigation over social media's impact on minors.
The decision, handed down in Los Angeles County Superior Court after more than 40 hours of deliberations, concluded that the companies' platforms were negligently designed. Jurors determined that features such as autoplay and infinite scrolling were a "substantial factor" in causing harm to the plaintiff, identified in court as Kaley G.M.
The financial award includes:
- $3 million in compensatory damages
- $3 million in punitive damages
- Allocation of liability: 70% to Meta, 30% to YouTube
Jurors further found that the companies "acted with malice, oppression, or fraud" in the way their products were built and marketed, a legal threshold that opens the door to punitive penalties.
The case, closely watched by regulators and legal analysts, is being treated as a potential bellwether for hundreds of similar lawsuits filed across the United States. Plaintiffs in those cases argue that social media companies engineered engagement systems that disproportionately affect minors' mental health.
During the six-week trial, testimony detailed the plaintiff's early and sustained exposure to digital platforms. She began using YouTube at age six and joined Instagram at nine, spending extended periods on both services throughout her formative years.
Attorneys for the plaintiff argued that platform architecture-including algorithm-driven recommendations, continuous content feeds, and autoplay-was deliberately designed to maximize user retention. Expert witnesses described these mechanisms as behavioral reinforcement systems that can amplify compulsive usage patterns among younger users.
The defense rejected those claims. A Meta spokesperson said that "teen mental health is profoundly complex and cannot be linked to a single app," adding, "We will continue to defend ourselves vigorously as every case is different, and we remain confident in our record of protecting teens online."
Google similarly disputed the findings, stating that the case "misunderstands YouTube, which is a responsibly built streaming platform, not a social media site."
