As of March 2026, no verdict has been reached in the landmark trial claiming Instagram and YouTube are addictive—the case remains ongoing with the first trial having begun in January 2026 in Los Angeles Superior Court. A 20-year-old plaintiff identified as K.G.M. has become the first person to take major social media companies to trial over addiction allegations, with the case now in active proceedings before a California judge.

What’s Happening in the First Social Media Addiction Trial?
The trial began on January 27, 2026, in Los Angeles Superior Court as a consolidated JCCP case. The plaintiff, K.G.M., claims she used Instagram without parental knowledge starting at age 9, then increasingly relied on both Instagram and YouTube through her teenage years. Her legal team argues that the companies deliberately designed their platforms to be addictive, using features like beauty filters that manipulated her appearance (making eyes larger, noses smaller, adding makeup simulation) to keep her engaged and returning to the app.
As of March 2026, the trial remains active with no final verdict announced, meaning the court has not yet decided whether Meta (Instagram’s parent company) and YouTube engaged in deceptive or harmful practices. What makes this trial major is that it marks the first time a social media addiction claim has made it through initial dismissals and pretrial motions to reach actual trial testimony. Previous lawsuits were dismissed on various procedural grounds, but this case survived enough legal scrutiny to proceed to evidence presentation and witness examination.
The Plaintiff’s Mental Health Claims and Alleged Harm
K.G.M. alleges that her use of Instagram and YouTube led to significant mental health consequences, including the development of cutting behavior, depression, and other psychological harm she claims were directly caused or exacerbated by the addictive design of the platforms. Starting in her early teens, she reports that she began staying up late scrolling through content and skipping classes to use these apps—behavior patterns that addiction researchers recognize as hallmarks of compulsive platform use.
The plaintiff’s legal theory centers on the idea that the companies knew their platforms were addictive and chose not to implement safeguards, instead optimizing for engagement and advertising revenue at the expense of user mental health. However, causation in these cases is complex. While K.G.M.’s mental health struggles are real and documented, proving that Instagram and YouTube specifically caused them—rather than contributing to pre-existing vulnerabilities or being one factor among many—is the core dispute the trial is designed to resolve. The judge and jury will have to weigh evidence about the platform’s design choices, internal company research about addiction risks, and expert testimony about adolescent psychology and brain development.
How Many People Are Part of This Litigation?
This single trial is the tip of a much larger litigation wave. As of March 2026, there are over 2,407 social media addiction claims pending in the multidistrict litigation, with more than 1,600 plaintiffs total in consolidated cases specifically against Instagram, YouTube, TikTok, and Snap. Beyond individual claims, over 350 families and more than 250 school districts have joined litigation against these platforms, suggesting that concerns about social media’s impact on child development extend well beyond single teenagers.
Many of these claims follow similar patterns—young users alleging that the platforms’ design features deliberately fostered addiction, leading to mental health consequences. This scale is significant because if K.G.M. prevails, or even if she loses but establishes a clear legal standard for how these cases should be evaluated, it will affect the trajectory of all those pending claims. Conversely, if the defendants win decisively, they’ll likely cite this case when opposing similar lawsuits.
What Have Company Executives Testified?
During the trial, high-ranking executives from Meta and YouTube have taken the stand. Instagram head Adam Mosseri testified, as did Meta CEO Mark Zuckerberg himself—an unusually high-profile appearance that signals the case’s importance to the companies. YouTube VP of Engineering Cristos Goodrow also provided testimony.
The companies’ legal strategy appears to focus on arguing that user choice, parental responsibility, and individual differences in susceptibility to addiction—rather than deliberate company design—explain why some users develop problematic usage patterns. By having Zuckerberg testify directly, Meta took the risk of exposing its CEO to cross-examination by the plaintiff’s attorneys, but the company may have calculated that his presence would lend credibility and control the narrative around Meta’s intentions regarding user safety. YouTube’s participation with a VP-level executive shows Google/Alphabet also takes the litigation seriously.
Why Have TikTok and Snapchat Already Settled While Meta and YouTube Haven’t?
TikTok and Snapchat have already reached settlements with plaintiffs in this litigation, while Meta (Instagram’s parent) and YouTube (Google’s subsidiary) remain as active defendants with no settlement announced. This divergence likely reflects different legal risk calculations. By settling early, TikTok and Snapchat avoided the costs and exposure of a trial, but they also preserved the ability to deny wrongdoing as part of typical settlement agreements.
Meta and YouTube’s decision to proceed to trial suggests they believe their legal position is strong enough to justify the reputational and financial risks of a public verdict. However, this strategy carries a significant downside: if the jury rules against Meta or YouTube, the verdict could become a roadmap for thousands of other plaintiffs in the pending 2,407 claims. Settlements, by contrast, often include confidentiality provisions that limit how they can be used in future cases.
When Are the Next Trials Scheduled?
The judge has scheduled bellwether trials for June 15, 2026, and August 6, 2026. Bellwether trials are test cases selected to help the parties and the court understand how juries might respond to similar claims.
If these upcoming trials produce results that either side views as favorable, it could accelerate settlement negotiations for the remaining 2,400+ pending claims. If results are mixed or unpredictable, litigation could continue for years. The June and August trials will likely involve different plaintiffs with different fact patterns—perhaps older users, users from different platforms, or users with different documented harms—allowing both sides to test which arguments resonate with juries.
What Does No Verdict Yet Mean for Pending Claimants?
For the thousands of people with pending social media addiction claims, the lack of a verdict represents a critical moment of uncertainty. Until K.G.M.’s case concludes and the bellwether trials in June and August are completed, there is no legal precedent establishing whether these platforms can be held liable for addiction-related harm.
This means claimants cannot predict their own cases’ likely outcomes, and attorneys evaluating claims cannot confidently assess their value. This period of uncertainty may actually pressure both sides toward eventual settlements, since the defendants face exposure to potentially massive liability if they lose, while plaintiffs face the risk of verdicts that establish unfavorable legal standards if they lose. By late 2026 or 2027, the landscape will likely look very different depending on how these trials conclude.
