As of March 25, 2026, the landmark social media addiction trial in California remains awaiting its verdict—a jury in Los Angeles Superior Court has been deliberating for over a week after six weeks of testimony, with no decision yet announced. However, the landscape shifted dramatically just days earlier when a New Mexico jury delivered a verdict on March 24-25, 2026, finding Meta liable and awarding $375 million in damages for harming children’s mental health and violating state consumer protection laws. These two cases represent the most significant legal tests of whether social media companies knowingly designed addictive platforms that damaged young users’ mental health—and they’re happening simultaneously.
The California case involves a 20-year-old plaintiff, K.G.M., who claims Meta’s Instagram and Facebook were designed to exploit psychological vulnerabilities, leading to her addiction, depression, and suicidal thoughts. The defendants remaining in the trial are Meta and Alphabet’s YouTube, though TikTok and Snapchat settled before trial for undisclosed amounts.

What Is the Status of the California Social Media Addiction Trial?
The jury in Los Angeles Superior Court began deliberating on March 13, 2026, after closing arguments concluded on March 12. The case itself started on January 27, 2026, meaning jurors heard six weeks of testimony before retiring to decide whether meta and YouTube designed their platforms to addict users. As of mid-March, the jury was still working through the evidence—a sign that they’re carefully weighing a complex case involving product design, algorithm manipulation, and psychological harm. One critical moment in the trial came on March 3, 2026, when Mark Zuckerberg testified to defend Meta against claims that Instagram and Facebook were intentionally designed to keep users scrolling. His testimony on whether the company knowingly exploited addiction mechanics became a focal point of the plaintiff’s case.
The jury had to weigh Zuckerberg’s defense against expert testimony and internal company documents presented by K.G.M.’s legal team. No verdict date has been announced, and deliberations have taken more than a week—suggesting the jury is not rushing to judgment on this unprecedented case. This trial is a bellwether case, meaning its outcome could set legal precedent for thousands of similar pending lawsuits. If the jury finds Meta and YouTube liable, it opens the door for many other plaintiffs to advance their addiction claims. If they find the defendants not liable, it could slow momentum in other cases. The stakes extend beyond the parties in the courtroom to the broader litigation landscape.
The New Mexico Verdict—What Changed on March 24-25, 2026?
While California jurors were still deliberating, a jury in New Mexico reached a decision on March 24-25, 2026, finding Meta liable for harming children’s mental health and violating New Mexico’s Unfair Practices Act. The verdict awarded $375 million in damages—a substantial sum that reflects the jury’s finding that Meta failed to protect children from sexually explicit content and knowingly hid what it understood about the dangers of child sexual exploitation and mental health impacts on its platform. The New Mexico finding is significant because it represents the first jury verdict definitively holding Meta liable in a social media addiction context, though the specifics differ slightly from the California case. The New Mexico jury focused on Meta’s failure to protect children from predatory content and the mental health consequences, while the California case centers more directly on addiction design.
Meta has stated it disagrees with the New Mexico verdict and plans to appeal, signaling that this decision will likely be contested in appellate courts. However, if X then Y applies here: if the New Mexico verdict survives appeal, it could serve as persuasive authority for other state courts considering similar claims. Conversely, if Meta successfully appeals and reduces or eliminates the $375 million judgment, it could undermine the credibility of the New Mexico jury’s findings in the eyes of other juries. The appeals process for this verdict will take months or potentially years.
Why These Cases Matter—The Bellwether Effect and Legal Precedent
Both the California and New Mexico cases are testing whether courts will formally recognize social media addiction as a cognizable injury in law. For decades, addiction claims have centered on substances like drugs or alcohol, with clear physiological mechanisms. Social media addiction presents a novel legal theory: that algorithmic design and engagement manipulation can create psychological dependence that causes measurable mental health damage. A California verdict finding Meta and youtube liable would validate this theory for the first time in a jury trial. The California case is explicitly recognized as a bellwether—a test case whose outcome signals how similar cases might proceed. As of February 2026, there are approximately 2,325 active claims involving social media addiction, up from 1,867 in July 2025.
Nearly 800 school districts across the nation have also joined lawsuits alleging that Meta, TikTok, and Snapchat designed addictive platforms that harmed students’ ability to learn. If a California jury returns a verdict for K.G.M., these thousands of claims gain momentum. If they return a verdict for the defense, plaintiffs’ attorneys will need to reassess strategy, though the New Mexico verdict would still provide some precedent. The precedent question extends to regulatory support as well. In September 2025, a 9th Circuit panel upheld California’s Protecting Our Kids from Social Media Addiction Act, including a requirement for platforms to offer a private mode for minors. This regulatory validation of concern about social media addiction strengthens the legal argument that companies have a responsibility to mitigate addictive design—a position that bolsters plaintiffs’ cases.
TikTok and Snapchat’s Pre-Trial Settlements—What Did They Know?
Before the California trial even began, TikTok and Snapchat chose to settle their roles in the case rather than face a jury. While the settlement amounts remain undisclosed, the decision to settle rather than defend speaks volumes about the defendants’ risk calculation. Both companies apparently determined that the cost of settling was preferable to the uncertainty of a jury verdict or the reputational damage of a trial. When defendants settle before trial in a high-profile case, it typically signals they viewed their legal position as weak or saw trial as an unacceptable business risk. Meta and YouTube decided to stay in the fight, arguing their case in court, while TikTok and Snapchat opted out.
This creates an interesting dynamic: if Meta and YouTube lose, they’ll have paid the price of defending the case and still owed a verdict. If they win, they’ll claim vindication, though TikTok and Snapchat will have already paid for settling. For future plaintiffs, the settlement itself—even with undisclosed terms—becomes evidence that these platforms understood the addiction risk. The comparison here matters: defendants that believe they can win typically don’t settle, but those that see liability as likely do. Snapchat and TikTok’s settlements suggest their legal teams advised caution, while Meta’s decision to try the case reflects either greater confidence in their position or a corporate decision that losing to one plaintiff is preferable to mass settlement that implies guilt.
The Broader Litigation Landscape—Thousands of Cases Pending
Beyond the California trial, social media addiction claims are accumulating across the country. As of February 2026, approximately 2,325 active claims have been filed, representing individuals who believe social media platforms harmed their mental health. This number has grown steadily—it was 1,867 just seven months earlier in July 2025. Each of these claims is potentially affected by the outcomes in California and New Mexico. School districts represent another major litigation front. Nearly 800 school districts nationwide have joined lawsuits alleging that Meta, TikTok, and Snapchat designed addictive platforms that interfered with students’ ability to focus and learn.
These district claims take a different angle than individual addiction claims: they frame the problem as a public nuisance affecting institutional operations, not just individual mental health. If school district claims succeed, they could result in massive damages and injunctive relief forcing platform redesigns. A critical limitation to note: not all of these 2,325 claims will survive to trial or settlement. Many will be dismissed on procedural grounds, lack sufficient evidence, or be consolidated into larger class actions. The legal system moves slowly, and many of these claims won’t be resolved for years. However, each verdict or settlement provides data that informs whether future claims are likely to succeed, making the California and New Mexico outcomes pivotal for case management.
How Courts Are Recognizing Mental Health Damage from Algorithm Design
What makes these addiction cases novel is that they require courts to accept a theory of harm based on algorithm and design rather than a toxic substance. The plaintiff in California, K.G.M., presented expert testimony about how Instagram and Facebook’s engagement algorithms—which prioritize content that triggers strong emotional reactions—can manipulate dopamine responses and create psychological dependence. The New Mexico verdict suggests at least one jury found this theory credible.
Mark Zuckerberg’s March 3 testimony addressed whether Meta knowingly designed Instagram and Facebook to be addictive. This is the crux: if Meta understood its platform’s addictive properties and intentionally amplified them for engagement and profit, it crosses from negligence into deliberate wrongdoing. The jury in California had to evaluate whether internal company knowledge—documents about “time spent” goals and engagement metrics—constituted proof of intentional addiction design. The New Mexico jury apparently decided that Meta’s knowledge of child exploitation risks and mental health harms, combined with its failure to adequately protect children, was sufficient for liability.
What Comes Next—Appeals, Regulatory Action, and Future Litigation
The next chapter for both cases involves appeals. Meta will likely appeal the New Mexico verdict, arguing either that the evidence didn’t support the jury’s findings or that the $375 million award is excessive. If the California jury delivers a verdict, whichever side loses will probably appeal. These appellate processes typically take 1-2 years, during which the cases will be on hold and the verdicts technically stay in effect but enforceable.
Meanwhile, regulatory momentum is building alongside litigation. The 9th Circuit’s September 2025 decision upholding California’s social media addiction law suggests that courts and legislatures are prepared to impose requirements on social media platforms to protect minors. Additional regulation—requiring private modes, limiting algorithmic recommendations, or mandating clearer disclosure of addiction risks—could emerge from state legislatures or potentially federal action. If regulation passes, it may accelerate settlement of pending litigation by raising the cost of continued non-compliance. The combination of jury verdicts and regulatory pressure creates a convergence that favors future plaintiffs and settlement momentum.
