A California jury will hear the first courtroom test of claims that major social media platforms used addictive design features that harmed a teenager’s mental health.

A landmark trial accusing major social media companies of fueling youth addiction and mental health harm opened this week in California, marking the first time Meta, TikTok, and Google-owned YouTube have been required to defend such claims before a jury.

According to Reuters, the bellwether case is being heard in Los Angeles County Superior Court and centers on a 19-year-old California woman identified in court filings as K.G.M. She alleges that she became addicted to social media platforms at a young age due to their attention-driven design features, contributing to depression and suicidal ideation.

The trial represents the first in a series of lawsuits expected to proceed this year alleging that social media companies negligently designed products that harmed children and teenagers. Jurors will be asked to decide whether the platforms materially contributed to K.G.M.’s mental health struggles and whether their conduct outweighed other potential influences, including third-party content and factors in her offline life.

Matthew Bergman, the plaintiff’s attorney, said the proceedings mark a turning point because the companies will face scrutiny that goes beyond congressional hearings, with sworn testimony and cross-examination before a jury.

Legal observers described the case as a test of whether emerging theories linking social media design to psychological harm can withstand judicial review. Clay Calvert, a media law expert at the American Enterprise Institute, said the trial will reveal how well such claims hold up under evidentiary standards applied in court.

Meta CEO Mark Zuckerberg is expected to testify during the proceedings. Meta has said it will argue that its platforms did not cause K.G.M.’s mental health challenges. Snap CEO Evan Spiegel had also been expected to testify, but Snap reached a settlement with the plaintiff on Jan. 20, according to Breitbart. A Snap spokesperson declined to disclose the terms of that agreement.

YouTube plans to argue that its services are fundamentally different from platforms such as Instagram and TikTok and should not be treated as traditional social media in the context of addiction claims. TikTok has declined to comment publicly on its legal strategy.

At the same time they face litigation, the companies have expanded efforts to demonstrate a commitment to teen safety. Meta has sponsored parent workshops at high schools nationwide since 2018, including a Screen Smart event held in Los Angeles in 2024 featuring National PTA President Yvonne Johnson and Meta safety chief Antigone Davis. Meta has said these efforts reflect its broader focus on youth protection, as outlined in a company blog post.

TikTok has promoted similar initiatives through its Create with Kindness program, partnering with more than 100 local and regional Parent-Teacher Associations to educate families on parental control tools and screen-time limits. Google, YouTube’s parent company, has partnered with the Girl Scouts to provide digital safety education, offering badges to participants who complete lessons on online behavior and privacy.

The outcome of the California trial is expected to influence how courts nationwide handle a growing wave of lawsuits alleging that social media platforms played a direct role in a youth mental health crisis.
