Meta Platforms faces a landmark federal jury trial starting August 18, 2026, in Oakland, California. Thirty US states allege Meta deliberately designed Facebook and Instagram to encourage compulsive use by children and teens, violating privacy and consumer protection laws [1, 2, 3, 4].

The lawsuit claims Meta harmed young users through addictive features and collected data from children under 13 without parental consent [1, 3]. Plaintiffs seek financial penalties up to $1.4 trillion, nearly equal to Meta’s $1.5 trillion market value, though legal experts view this maximum as largely theoretical and unlikely to be fully imposed [5, 3, 6, 7, 8]. About two-thirds of the US population is represented by these 30 states [1, 2].

The trial’s initial phase includes four states—California, Colorado, Kentucky, and New Jersey—with others scheduled to join later [3, 7]. Plaintiffs demand wide-ranging platform changes: removing "like" counts for users under 18, ending infinite scrolling and autoplay videos, disabling certain filters, requiring parental verification, banning multiple accounts, ending ephemeral formats like Instagram Stories, and restricting push notifications to daytime hours [1, 2, 4].

Past rulings have cautioned Meta’s platforms cause public health harms. A New Mexico judge labeled Meta a "public nuisance" and ordered limits on likes, notifications, and content [1, 2, 4]. Meta lost related cases in New Mexico and Los Angeles earlier this year but plans to appeal [2, 7, 8].

Meta denies the allegations and says it is committed to supporting young users. A company spokesperson said, "We strongly oppose these allegations and believe the evidence will prove our longstanding commitment to supporting young people." The company also notes it has submitted over 2 million documents including internal research showing Instagram can drive social comparison, loneliness, and negative emotions among youth [1, 2, 7].

Legal experts warn the stakes are high. Eric Goldman, law professor at Santa Clara University, said, "The stakes could not be higher in this case" [5]. The federal jury will weigh both monetary penalties and potential court-ordered changes to Meta’s platforms nationwide.

The trial is scheduled to begin tomorrow, marking a major test of accountability for social media’s role in youth mental health and privacy.
