After more than eight days of deliberations, the jury in Los Angeles still has not reached a verdict in a landmark lawsuit that alleges Meta and YouTube deliberately designed addictive features to harm users’ mental health. As of March 25, 2026, jurors remain deadlocked, struggling to reach consensus on at least one of the defendants in what has become the first trial to emerge from over 2,000 pending social media design lawsuits. This case centers on whether platforms intentionally built infinite scroll, push notifications, and beauty filters to maximize user engagement—and whether that design strategy caused measurable psychological harm to a young plaintiff identified as K.G.M.
The extended deliberation period itself signals the complexity of proving intentional harm through product design choices that platforms argue are industry standard. Meanwhile, just one day before the Los Angeles jury began struggling toward a verdict, a New Mexico jury reached a very different conclusion: they found Meta liable and ordered the company to pay $375 million in civil penalties for consumer protection violations related to child safety.

How Long Can a Jury Deliberate Without Reaching a Verdict in a Social Media Design Case?
The Los Angeles jury’s inability to reach consensus after eight or more days of deliberations is not unusual for complex civil cases, but it does signal genuine disagreement among jurors about the evidence and legal standards they’ve been asked to apply. In trials involving product liability and consumer harm, jurors often grapple with fundamental questions: Did the company know what it was doing? Did the company intend to cause harm? Can you prove that intention from internal documents and testimony? These questions require jurors to interpret evidence—emails, design documents, expert testimony about algorithms—and weigh competing expert opinions about how social media affects mental health. When deadlock occurs in a civil case like this one, judges typically allow deliberations to continue for an extended period before declaring a mistrial.
Unlike criminal cases, where a hung jury may result in a new trial or acquittal, a civil hung jury creates uncertainty: the case may need to be retried, settled, or potentially appealed on procedural grounds. The longer jurors deliberate without resolution, the more pressure they may face to compromise—but compromise on liability in a multi-million-dollar case raises its own questions about fairness and the integrity of the verdict. For the plaintiffs, a hung jury is neither victory nor defeat; it’s a reset button that comes with additional legal costs and delays.
What Specific Design Features Are Meta and YouTube Accused of Using to Hook Users?
The lawsuit targets three specific design elements that have become ubiquitous across social platforms: infinite scroll, push notifications, and beauty filters. Infinite scroll removes the natural stopping point that older social media designs had—when you reached the end of a page, you had to consciously choose to load more content. With infinite scroll, the feed simply continues as you swipe or scroll, creating a seamless experience that makes it easy to lose track of time. Meta pioneered this feature years ago, and youtube adopted similar mechanics through its autoplay function, where the next video automatically begins without user intervention.
Push notifications serve a different but equally powerful function: they interrupt whatever a user is doing with an alert that someone has liked their post, commented on their content, or that new content is available. These notifications create a variable reward schedule—the psychological mechanism behind slot machines—where users check their phones hoping for positive social feedback. Beauty filters, meanwhile, allow users to digitally enhance their appearance in photos and videos, creating a gap between how they look online and in real life. The lawsuit argues that this gap encourages continued use as users chase the dopamine hit of seeing themselves look “better” and receiving likes on filtered images. However, if users simply stop opening the app, none of these features matter—the argument is that the features are designed specifically to make stopping difficult.
Why Is This Los Angeles Trial Being Called the First Bellwether Case, and What Does That Mean?
A bellwether case is the first to go to trial from a large group of similar lawsuits, and its outcome often influences how thousands of other cases are resolved. The legal landscape surrounding social media design and mental health involves more than 2,000 pending lawsuits, with 20 cases designated as formal bellwether cases that will be tracked closely by judges, other plaintiffs’ attorneys, and defendants. The Los Angeles trial is the first bellwether case to actually reach a jury verdict—or in this case, attempted verdict. If the jury finds Meta and YouTube liable, the verdict sends a signal to the defendants and the broader litigation ecosystem: juries will hold social media companies accountable for design choices that they view as deliberately harmful.
A successful verdict in the Los Angeles case could accelerate settlement discussions in the other 1,999 pending cases, as defendants calculate the cost of defending each case against the cost of resolving them en masse. Conversely, if the jury hangs or rules against the plaintiffs, defendants gain use to push for dismissals or unfavorable settlements in the backlog of cases. The judge in the Los Angeles case must still rule on what happens next—whether to declare a mistrial, allow further deliberations, or explore a partial verdict on some counts. This decision will ripple across the entire litigation landscape and affect the timeline for thousands of plaintiffs waiting for their day in court.
What Could Happen Now That the Jury Is Deadlocked on at Least One Defendant?
If the jury has reached consensus on one defendant but not the other—for example, finding Meta liable but not YouTube, or vice versa—the judge may accept a partial verdict while continuing deliberations on the holdout defendant. Alternatively, if the jury indicates that further deliberation is unlikely to produce agreement on any count, the judge may declare a mistrial. In that scenario, the case could be retried with a new jury, a settlement could be negotiated based on the information the current jury revealed (through jury interviews after the verdict is recorded), or the plaintiffs could appeal procedural errors they believe prejudiced the case.
The practical timeline matters for plaintiffs like K.G.M., who has already spent years in litigation waiting for this trial to begin and conclude. A mistrial followed by a retrial could add two to three more years before a final verdict is reached. A settlement, by contrast, could be reached within weeks or months if both sides see a hung jury as a signal that neither side has a clear path to victory. For Meta and YouTube, the cost calculation includes not just this trial but the precedent it sets: a hung jury or partial verdict is murkier than a clear win, and it may make settlement more attractive than gambling on a retrial where a new jury might be more sympathetic to the plaintiffs.
How Does the New Mexico Verdict Change the Equation for These Cases?
Just one day before the Los Angeles jury entered its eighth day of deliberations, a different jury in New Mexico reached a clear and decisive verdict: Meta was liable under the state’s consumer protection laws and must pay $375 million in civil penalties. The New Mexico case followed a different legal theory—focusing on whether Meta violated consumer protection laws by misleading residents about the platform’s safety and allowing predators unfettered access to minors—but the core question overlaps with the Los Angeles case: Did Meta deliberately create conditions it knew would harm users? The New Mexico verdict, reached after a six-week trial with 40+ witnesses and hundreds of reviewed documents, suggests that juries are willing to hold social media companies accountable.
However, the New Mexico case involved child exploitation and predator access, which may be a more sympathetic claim to jurors than the mental health and addiction arguments in the Los Angeles case. Not all juries will reach the same conclusion on the same evidence, and mental health causation is notoriously difficult to prove compared to child safety violations. Additionally, Meta has already announced it “respectfully disagree[s] with the verdict and will appeal,” suggesting the New Mexico verdict is not the final word—it may take years of appellate litigation before that $375 million penalty is actually paid or upheld by a higher court.
What Does the Mental Health Argument Actually Require a Jury to Believe?
To find Meta and YouTube liable in the Los Angeles case, the jury must believe that the defendants’ design choices were intentional, that those choices caused measurable psychological harm to the plaintiff, and that the defendants understood the risk of that harm when they deployed these features. This is a higher bar than simply saying, “These design features are addictive.” The jury has seen expert testimony arguing that infinite scroll, notifications, and beauty filters trigger dopamine responses similar to gambling; they’ve likely seen internal Meta documents discussing engagement metrics and user retention.
But they’ve also heard testimony from defense experts arguing that correlation between social media use and mental health issues does not prove causation, and that billions of users experience these features without serious psychological harm. The plaintiff’s case lives or dies on the credibility of this causal chain: Does Meta’s design cause depression, anxiety, or body dysmorphia, or do depressed, anxious, and body-conscious people simply use social media more? Did Meta know this distinction existed and proceed anyway? These questions require jurors to interpret scientific evidence, weigh expert credibility, and make judgments about corporate intent based on circumstantial evidence. A hung jury suggests that not all jurors agree on where that burden of proof has been met—a powerful reminder that even in cases with substantial evidence of harm, proving intentional wrongdoing through product design remains legally and conceptually complex.
What Could These Cases Mean for the Future of Social Media Regulation?
The 2,000+ pending social media design lawsuits represent a shift in how courts and juries are asked to evaluate platform responsibility. Rather than waiting for legislative action or regulatory enforcement, plaintiffs’ attorneys are building a case law record that could eventually force changes to how social platforms operate. If enough juries side with plaintiffs, or if settlements reflect substantial financial liability, platforms may face pressure to redesign core features—removing infinite scroll, limiting notification frequency, or disclosing the mental health risks of beauty filters in the same way tobacco products carry health warnings.
However, the Los Angeles jury’s prolonged deliberations and the appeal Meta has already filed in the New Mexico case suggest that this transition will not happen quickly or decisively. The legal system moves slowly, and even a $375 million verdict is often viewed as a cost of doing business rather than a fundamental change in operations. The real pressure will come not from individual verdicts but from the cumulative weight of 2,000+ cases, the insurance costs of defending them, and the reputational damage of losing repeatedly. For now, users and parents concerned about social media’s mental health impact must rely on individual choices, school initiatives, and advocacy—while lawsuits like the one in Los Angeles slowly work their way through the system.
