The jury in the landmark Los Angeles social media addiction trial involving Meta and YouTube resumed deliberations on March 25, 2026, after signaling a possible stalemate on at least one defendant just days earlier. The jury has been deliberating since March 13, 2026—more than a week into what could become a historic decision about whether major social media platforms bear legal responsibility for engineering addiction-like features that harm young people’s mental health.
This case involves K.G.M., a 20-year-old from Chico, California, who claims Meta and YouTube deliberately used “engineered addiction” design features to cause psychological harm. Meanwhile, a related but separate verdict just delivered on March 24 in New Mexico adds crucial context: a jury there found Meta liable for $375 million in damages for violations of the state’s unfair practices act, marking the first state to prevail at trial against a major tech company over claims it harmed children through its platforms.

What Does the Stalemate Mean in the Los Angeles Meta and YouTube Trial?
When a jury signals it may be “deadlocked”—unable to reach unanimous agreement—the judge must decide whether to push them to continue deliberating or declare a mistrial. In the LA trial, this signal came after approximately two weeks of jury discussion about whether meta and YouTube knowingly designed their platforms to create addictive engagement patterns that specifically harmed the young plaintiff. A deadlock on “at least one defendant” suggests jurors may have reached consensus against one company but remain divided on the other, or that they’re split across the board. The case itself is extraordinarily complex: the plaintiff’s legal team had to prove not just that the platforms caused harm, but that the companies intentionally designed specific features—like algorithmic recommendation systems, notification systems, and infinite scroll—knowing these would trigger compulsive use patterns in young users.
The deliberations that resumed on March 25 represent the jury’s effort to find common ground after this stalemate signal. California courts typically encourage jurors to continue deliberating rather than immediately declare a mistrial, so the judge likely gave them instructions (sometimes called “Allen instructions”) encouraging them to reconsider their positions and work toward unanimity. However, there’s no guarantee this will succeed. If the jury remains deadlocked after further deliberation, the judge will declare a mistrial, and the case would either proceed to a new trial or potentially settle—a significant outcome either way, since it would mean no clear liability finding against Meta or YouTube on these specific claims.
The New Mexico Verdict: $375 Million Against Meta for Child Safety Violations
Just one day before the LA jury’s continued deliberations, a jury in New Mexico delivered a verdict that fundamentally shifts the Meta litigation environment. On March 24, 2026, jurors found Meta liable for $375 million in damages for violating New Mexico’s Unfair Practices Act by engaging in “unconscionable” trade practices that harmed children’s mental health and concealed knowledge of child sexual exploitation on its platforms. This is not a settlement—it’s a verdict reached after a full trial, making it legally far more significant. The jury determined that Meta committed thousands of separate violations, with each one counting toward the penalty structure.
What makes the New Mexico verdict historic is that it represents the first state to prevail at trial against a major technology company over claims that the company’s platform design harmed children. Previous Meta settlements and legal actions have either settled before trial or resulted in regulatory fines, but this is a jury of ordinary citizens finding the company liable for harm to minors. The verdict also specifically found that Meta engaged in practices that “harmed children’s mental health” and “concealed knowledge of child sexual exploitation”—two distinct categories of harm that reinforce the narrative plaintiff lawyers are pushing in cases like the LA trial. Importantly, the judge will determine in May whether Meta created a “public nuisance,” which could result in additional damages for public remediation programs. Meta has stated it “respectfully disagrees with the verdict and will appeal,” signaling a lengthy appellate process ahead.
How the New Mexico Victory Influences the LA Trial Jury
The timing of the New Mexico verdict—coming right as the LA jury signaled a stalemate—creates what trial lawyers call a “demonstration effect.” Jurors in the LA case may be aware that another jury in a similar case just found Meta liable for massive damages. However, there are strict rules about what information jurors receive during deliberations, and the judge would only inform them if they explicitly asked whether other cases existed. The LA trial and the New Mexico case have significant differences: the New Mexico case focused on child safety and exploitation, while the LA trial centers on addiction-like design features and mental health impacts on a single young plaintiff. The defendants also differ (New Mexico was Meta alone; LA involves both Meta and YouTube), and the legal theories vary.
That said, the New Mexico verdict objectively proves that a jury of ordinary people found Meta’s practices regarding children’s harm to be legally actionable and damages-worthy. This reinforces arguments that the design and operation of social media platforms do cause documented injury to young users. The LA jury may be more likely to reach consensus knowing that another jury already sided with plaintiffs on a related Meta child safety case, though such reasoning would technically be improper. What’s undeniable is that the New Mexico verdict removes the “first company to lose at trial” barrier—it’s no longer unprecedented for a tech giant to face jury liability for platform design harms to children.
What Are the Specific Claims Against Meta and YouTube in the LA Case?
The LA plaintiff alleges that Meta (Facebook and Instagram) and YouTube employed “engineered addiction” features—deliberately designed mechanisms to maximize user engagement at the expense of mental health. These claims include algorithmic recommendation systems that promote content known to trigger excessive use, notification and alert systems designed to pull users back to the apps, infinite-scroll features that eliminate natural stopping points, and variable reward schedules (unpredictable content feeds) that mimic gambling mechanics. The plaintiff’s team presented evidence about internal Meta research and company documents showing that executives were aware these design choices could harm teenage mental health, yet continued or expanded these features to drive user engagement and ad revenue.
The defense strategy centered on distinguishing platform design from personal circumstances. Meta and YouTube argued that the plaintiff’s mental health struggles stemmed from family and social factors unrelated to platform features—essentially, that home life, not algorithm design, caused the harm. This is where the “deadlock” signal becomes critical: some jurors may believe the platform’s design contributed to harm, but disagree on whether the contribution was substantial enough to hold the company legally liable, or whether other factors were equally or more responsible. The approximately seven-week trial presented weeks of expert testimony, internal company documents, and personal testimony about the plaintiff’s experience with social media and mental health decline.
What Happens If the Jury Remains Deadlocked?
If the jury cannot reach unanimity after the judge encourages continued deliberation, the judge will declare a mistrial. This doesn’t mean the plaintiff lost—it means no verdict was reached. The case would then proceed to one of several outcomes. The plaintiff’s legal team could file for a new trial, which would require months or years of litigation, re-discovery, and re-trial preparation. Alternatively, the parties might negotiate a settlement now that a mistrial has been declared and the evidence has been aired in open court.
Settlement values after a deadlocked jury are often lower than they would be after a plaintiff victory, but higher than they might have been before trial. The defendants might use a mistrial to avoid the uncertainty of a retrial and settle to avoid the risk of an outright loss. From a broader litigation perspective, a mistrial in a high-profile case like this one doesn’t resolve the legal question of platform liability for addiction-like design. It leaves the question open for other plaintiffs and other courts. However, it does represent a failure to convince all jurors of the claims—a signal that the evidence, legal theories, or presentation may need refinement for future cases. Conversely, a deadlock also suggests the case is close, and the jury took the plaintiff’s claims seriously enough to deliberate intensely for more than two weeks.
Timeline and Procedural Next Steps
The LA trial began approximately seven weeks before March 25, placing the trial start around early February 2026. Jury selection, opening statements, plaintiff case presentation, defendant case presentation, expert testimony from both sides, and closing arguments all occurred within that seven-week window—a substantial but not unusually long timeline for a complex civil case. Deliberations began on March 13, meaning jurors spent about two weeks (with weekends off) discussing and debating the evidence before the stalemate signal around March 24. On March 25, the jury resumed deliberations, presumably under the judge’s instructions to continue working toward unanimous agreement.
No specific deadline has been announced for when the jury must reach a decision or declare itself deadlocked beyond repair. Typically, judges give jurors at least one additional week of deliberation time after a stalemate signal before declaring a mistrial. This means a decision or mistrial declaration in the LA trial could come by early April 2026. Meanwhile, the New Mexico case moves into its next phase: a May 2026 hearing where the judge will decide on the public nuisance question and potential additional damages for remediation programs. These parallel timelines mean Meta will be navigating critical liability determinations across multiple jurisdictions over the next several weeks.
The Broader Implications for Tech Platform Litigation
The New Mexico verdict and the LA trial deadlock together suggest that juries are willing to hold social media companies accountable for platform design choices affecting children, even in the absence of a single, dramatic injury or death. This marks a significant shift in how courts treat technology companies. For decades, tech firms argued that users choose to use their platforms and bear responsibility for their own engagement; this narrative appears to be eroding in jury proceedings. The legal claims in these cases—that algorithms and notification systems constitute “engineered addiction” akin to predatory design—are gaining traction in ordinary people’s eyes, even if not unanimously.
Looking forward, the outcomes in New Mexico and the LA trial will likely influence dozens of pending cases. If Meta loses the LA trial, the resulting damages award and legal precedent will embolden other plaintiffs and their lawyers. If a mistrial is declared, some will view it as a setback but others will see it as close enough to suggest a second jury might side with the plaintiff. Either way, Meta and YouTube face a cascade of similar litigation over the coming years, covering not just addiction claims but also mental health harms, child safety, data privacy, and algorithmic amplification of harmful content. The New Mexico verdict has already proven it’s possible for a state to prevail at trial; the LA jury’s ongoing deliberations will help determine whether the addiction-and-design theory specifically can command jury consensus.
