As of March 25, 2026, a jury in Los Angeles Superior Court is in its ninth day of deliberations in a landmark case alleging that Meta and YouTube knowingly designed addictive features that harmed a young plaintiff’s mental health—marking the first case of its kind to reach trial among hundreds of pending social media addiction lawsuits nationwide. The jury, overseen by Judge Carolyn B. Kuhl, has already moved past the liability phase and is now determining the amount of damages owed, though they reported difficulty reaching consensus against one defendant earlier this week.

What Is the Central Claim in This Landmark Social Media Addiction Case?
The lawsuit was filed by K.G.M., a 20-year-old plaintiff from Chico, California, who alleges that social media platforms intentionally designed addictive features that caused her to develop anxiety, depression, and body dysmorphia beginning in adolescence. Unlike typical product liability cases involving physical injury or defective goods, this case challenges whether social media companies’ algorithmic designs and engagement-focused features constitute a form of harm to adolescent mental health. The plaintiff names meta and YouTube as defendants, though both TikTok and Snap previously settled the case before trial, suggesting their own assessment of litigation risk.
This case is significant because it is the first of hundreds of pending social media addiction lawsuits to actually reach a jury verdict phase. Many other cases have been filed across the country alleging similar harms—psychological injuries claimed to result from design features that maximize user engagement and time spent on platforms. The fact that this case proceeded to trial, rather than settling like others, means the jury’s decision will carry particular weight in shaping how future cases are negotiated and what damages might be recoverable.
How Far Have Jury Deliberations Progressed, and What Are They Deciding Now?
jury deliberations began on March 13, 2026, following closing arguments delivered on March 12. As of March 25, the jury has been deliberating for nine days—a substantial duration that suggests complexity in weighing evidence and reaching consensus. A key development occurred on Friday, March 22, when the jury moved beyond the liability phase (deciding whether defendants are responsible for the harm) and advanced to the damages phase (deciding how much to award if liability is found). This progression indicates the jury has reached agreement that at least one defendant bears responsibility for the plaintiff’s claimed injuries.
However, on Monday, March 24, the jury sent a note to Judge Kuhl indicating difficulty reaching a verdict against one defendant, raising the possibility of a partial deadlock. When a jury cannot reach unanimity on some counts or defendants, courts may declare a mistrial on those specific issues, potentially requiring a partial retry. Judge Kuhl ordered the jury to continue deliberating rather than declaring an immediate mistrial, a common judicial practice intended to allow jurors more time to reach consensus before abandoning the effort. The distinction matters because a retrial is costly and time-consuming for all parties, so judges typically encourage continued deliberation if there is reasonable hope of resolution.
What Is the Timeline of This Litigation and How Did It Reach Trial?
The case reached trial during a period of intense scrutiny on social media platforms’ effects on youth mental health. Closing arguments on March 12, 2026, marked the conclusion of what was presumably several weeks of testimony from mental health experts, social media design specialists, and the plaintiff herself regarding the causal link between specific platform features and her psychological injuries. The relatively quick timeline from closing arguments to advanced deliberations suggests the jury has been working through the evidence systematically rather than getting stuck early in the process.
Prior to this trial, both TikTok and Snap reached pre-trial settlements with the plaintiff, which means they negotiated financial resolutions rather than risk a jury verdict. These settlements, though their terms have not been disclosed, signal that defendants recognize exposure to liability in social media addiction cases. Meta and YouTube chose not to settle, instead proceeding to full trial, a strategic decision that suggests confidence in their legal position or disagreement about appropriate damages valuations. The stakes are clearly high: a jury finding of liability could result in substantial damages that set precedent for hundreds of similar pending cases.
What Are the Legal Arguments and Positions of the Remaining Defendants?
Meta and YouTube’s position in the trial centered on disputing either the causal link between platform design and the plaintiff’s psychological injuries, the extent of harm, or both. Social media companies typically argue that while their platforms do use engagement-focused algorithms, they are not uniquely responsible for mental health issues that are multifactorial and influenced by genetics, family circumstances, peer relationships, and other environmental factors. They may also argue that users (and their parents) have agency to limit time spent and manage their own experience on platforms.
The plaintiff’s legal team, by contrast, argued that Meta and YouTube engaged in knowing design practices specifically intended to maximize user engagement and addiction, making their products inherently harmful to adolescents whose brains are still developing. This argument mirrors tobacco litigation strategy from decades past—claiming that a company’s design choices created foreseeable, severe harm even if other risk factors also exist. The jury’s advancement to the damages phase suggests they accepted at least some version of this causation argument for at least one defendant, though the difficulty reported on Monday indicates disagreement on perhaps the other defendant or on damage amounts.
What Damages Might the Jury Award, and What Would That Mean?
The damages phase that the jury is currently navigating involves deciding what dollar amount adequately compensates the plaintiff for her claimed injuries. In personal injury cases, damages typically include economic losses (medical treatment costs) and non-economic damages (pain and suffering, emotional distress). Social media addiction cases present unusual challenges because the “product” in question is technically free to the consumer, so economic damages may be limited to mental health treatment expenses unless the court allows recovery for lost opportunities or wages. Non-economic damages, however, could be substantial if the jury believes the plaintiff’s anxiety, depression, and body dysmorphia caused significant impairment.
A key consideration is that any award must be proportional to the harm caused—juries cannot impose punitive damages (penalties beyond actual harm) unless that is specifically authorized by law, which varies by state. The deliberation difficulty reported Monday may stem from disagreement about whether $500,000 versus $5 million versus some other amount properly reflects the plaintiff’s suffering. It may also reflect disagreement about apportionment—how much harm to attribute to Meta versus YouTube versus other contributing factors like the plaintiff’s own social media usage choices or family dynamics. Some jurors may believe the plaintiff bears shared responsibility that should reduce the defendants’ liability proportionally.
What Happened in the Separate New Mexico Case Against Meta?
A significant parallel development occurred on the same week as these Los Angeles deliberations: a separate jury in New Mexico found Meta’s platforms harmful to children in violation of state statutes and awarded $375 million in damages. This verdict, while from a different jurisdiction with different facts and legal standards, suggests that juries are increasingly willing to find social media companies liable for mental health harms to minors. The New Mexico award is substantially larger than typical settlements in similar cases, potentially influencing expectations for this Los Angeles jury’s damage award.
However, the New Mexico case differed in that it involved state consumer protection laws and potentially different evidence regarding Meta’s knowledge of specific harms. The Los Angeles case focuses on Meta and YouTube, whereas the New Mexico case centered on Meta alone. Damage awards can vary significantly based on jurisdiction, the plaintiff’s particular circumstances, the breadth of evidence presented, and jury composition. Still, the New Mexico verdict provides a data point suggesting juries in different states are reaching conclusions about social media platform liability, which may embolden both future plaintiffs and the Los Angeles jury.
What Happens If the Jury Reaches a Deadlock, and What Could This Case Mean for Pending Litigation?
If the jury cannot reach unanimity after continued deliberation, Judge Kuhl has the authority to declare a mistrial on the disputed counts. A mistrial is not a victory for defendants—it simply means the case would require retrial. However, retrial is expensive and uncertain, so both sides might choose to settle rather than pursue a second jury trial if a partial deadlock occurs. The cost of retrials, combined with the fact that one jury has already found liability on some counts, creates settlement pressure regardless of the mistrial declaration.
What makes this case historically significant is its position as the first-to-trial among hundreds of pending social media addiction cases. A substantial verdict or even a settlement resulting from jury pressure would likely accelerate resolutions in other pending cases, as defendants’ litigation costs and risk exposure become clearer. Conversely, a complete acquittal or very small award might embolden defendants to resist settling future cases. The jury’s decision here will ripple through the litigation landscape for years, influencing how mental health experts testify, how companies defend their design practices, and what damages negotiations looks like in a field that barely existed as litigation a few years ago.
