- Meta, TikTok, and Google’s YouTube face a Los Angeles jury accused of designing their apps to addict children
- This case marks the first “social media addiction” lawsuit scheduled to go before a jury this year
- Snap has resolved the same plaintiff’s claims through a confidential settlement
This week, a U.S. jury will hear the first major trial accusing Meta Platforms, TikTok, and Google’s YouTube of designing their social media platforms to addict children and damage their mental health.
This case arrives amid growing pressure from lawmakers, parents, and regulators demanding stricter limits on teens’ screen time, while companies battle to keep legal responsibility for online harms tightly restricted.
Plaintiffs’ lawyers see this as a bellwether case, a preview of how juries might react, with more youth mental health lawsuits expected to hit courtrooms throughout the year. The verdict could influence settlement talks in a wider batch of cases filed by families, school districts, and state attorneys general.
The plaintiff, a 19-year-old woman from California named K.G.M. in court documents, claims she got hooked on the apps early on due to their attention-grabbing design. She alleges the platforms worsened her depression and suicidal thoughts, and is pursuing unspecified damages.
Jurors must determine if the companies were negligent and if K.G.M.’s app usage played a significant role in her mental health issues, relative to other potential causes. The defendants argue that third-party content and offline factors offer alternative explanations.
Meta CEO Mark Zuckerberg is set to testify, with Meta insisting its products didn’t trigger the plaintiff’s mental health issues. A YouTube executive argued the platform is fundamentally different from Instagram and TikTok, urging the court not to treat them the same. TikTok, meanwhile, has chosen not to comment on its legal strategy.
Plaintiff lawyer Matthew Bergman warned the companies will undergo a form of cross-examination on Capitol Hill they can’t dodge: “They will be under a level of scrutiny that does not exist when you testify in front of Congress.” Media attorney Clay Calvert summed it up: “This is really a test case.” 1
Snap, the company behind Snapchat, was also named as a defendant but has reached a settlement with K.G.M. on undisclosed terms. That leaves Meta, TikTok, and YouTube as the primary defendants heading into trial. A Snap spokesperson declined to provide details about the agreement.
Both companies have worked to soften the blow to their reputations by launching new safety features and promoting them through public campaigns targeting parents. Meta sponsored school workshops in partnership with parent groups, TikTok showcased PTA-led sessions, and Google emphasized youth programs that include digital safety lessons.
Child-safety advocates argue these hearings will finally hold executives accountable for their product decisions after years of empty promises. “These are the tobacco trials of our generation,” said Sarah Gardner, CEO of the nonprofit Heat Initiative. Meta, meanwhile, insists it has “made real changes” and continues to “stand by our record of putting teen safety first.” The companies are also relying heavily on Section 230—a federal law that usually protects platforms from liability over user posts—even as the judge has directed jurors to weigh whether design elements themselves, beyond just content, played a role in causing harm. 2
The case may ultimately depend on evidence rather than outrage. “It’s a complex issue. Research doesn’t show that all digital media use is bad or addictive,” said Tamar Mendelson, a professor at Johns Hopkins Bloomberg School of Public Health, noting there’s no official psychiatric diagnosis for social media addiction. Eric Goldman, associate dean at Santa Clara University School of Law, pointed out the court still faces fundamental questions about causation: “How do we measure the causal components of that?” 3
The trial will stretch over several weeks. A win for the companies would weaken a rapidly expanding litigation tactic, while a decisive verdict for plaintiffs might reshape settlement values across the board.
