As of March 24, 2026, the jury in a high-profile social media addiction lawsuit remains deadlocked after more than eight days of deliberations, with no verdict in sight. The Los Angeles Superior Court jury, which began deliberating on March 13, is hearing a landmark case brought by a 20-year-old woman from Chico, California—referred to in court documents as K.G.M. and called “Kaley” by her legal team—against Meta (Facebook) and YouTube for allegedly using addictive design practices that contributed to mental health harms. The jury sent a note to Judge Carolyn B.
Kuhl on March 23 indicating they were having difficulty reaching a consensus on at least one of the remaining defendants, prompting the judge to order continued deliberations rather than declare a mistrial. This case has become a closely watched touchstone for the legal system’s approach to social media platforms and consumer protection, with hundreds of similar lawsuits pending across the country as this jury continues its work. The extended deliberation period itself signals the complexity and contentiousness of the issues before the jury. When jurors signal they are struggling to agree after more than a week of discussions, it typically means the evidence presented has genuine ambiguity or that the legal standards themselves present challenges for reaching consensus.

What Is This Lawsuit Actually About, and Who Are the Remaining Defendants?
The lawsuit centers on allegations that meta and YouTube employ design features specifically engineered to maximize user engagement through addictive mechanisms—infinite scrolling, algorithmic recommendations, variable reward schedules, and notification systems designed to trigger compulsive checking behavior. The 20-year-old plaintiff claims these practices contributed to mental health deterioration, including anxiety, depression, and other documented harms during her formative years as a heavy user of both platforms. Rather than arguing she should have simply used the apps less, her legal team contends that the platforms deliberately structured their products to override user self-control, making resistance to excessive use unreasonably difficult. The case treats social media addiction as an intentional design outcome, not an incidental side effect—a critical distinction in how courts assess liability.
Meta and YouTube remain as defendants because they rejected settlement offers before the trial began. TikTok and Snap, by contrast, chose to settle prior to trial. The settlements by TikTok and Snap did not require admission of wrongdoing but provided the plaintiff financial compensation in exchange for dropping claims against them. This divergence in settlement strategy reflects different corporate risk calculations: some platforms determined that settling a single-plaintiff case was more cost-effective than facing jury uncertainty, while Meta and YouTube apparently believed they had stronger legal defenses or wanted to contest the underlying claims more aggressively. The jury must now evaluate whether Meta’s and YouTube’s documented design practices constitute actionable harm under existing product liability and consumer protection law.
Why Has This Trial Become a Bellwether Case for Social Media Litigation?
this trial has become a focal point because hundreds of nearly identical lawsuits are pending against social media companies, filed by teenagers, young adults, and sometimes parents on behalf of minors. The legal system generally permits certain cases—called bellwether cases—to proceed to trial first when many similar cases are filed, allowing early resolution or establishing precedent that can guide settlement negotiations in the remaining lawsuits. If this jury returns a verdict holding Meta and youtube liable, it would strengthen the legal theory underlying hundreds of other claims and likely accelerate settlement discussions. Conversely, if the jury returns a defense verdict, it could narrow the legal pathway for future plaintiffs and potentially lead to dismissals of pending cases.
The significance extends beyond mere case logistics. This trial is one of the first opportunities for a jury to evaluate the scientific evidence about social media’s addictive design mechanisms in a formal legal setting. Expert testimony in the trial has addressed neurological research on reward systems, internal company documents about engagement optimization, and comparative data on platform design choices. The jury’s verdict—or deadlock—will signal whether a lay jury finds that evidence persuasive when presented in the context of legal standards like foreseeability, duty of care, and causation. No landmark verdict on this issue has yet been established, making this jury’s decision inherently consequential.
What Specifically Happened With the Jury’s Difficulty in Reaching a Verdict?
On March 23, the jury sent a note to Judge Carolyn B. Kuhl stating that members were unable to reach unanimous agreement on the verdict against one of the two remaining defendants. Under California law, jury verdicts in civil cases require unanimity—all twelve jurors must agree on the outcome. When a jury signals an impasse after substantial deliberation time, judges face a decision: order jurors to continue deliberating in hopes they can reach consensus, or declare a mistrial due to a hung jury.
Judge Kuhl chose to order the jury to continue, which is a legal option judges may exercise to encourage jurors to persist in their discussions and attempt to break through disagreement. The fact that jurors signaled difficulty regarding “one of the defendants” is particularly revealing. It suggests that the jury may have reached consensus on Meta but is divided on YouTube, or vice versa—meaning the jury possibly agrees that one company’s conduct was actionable but cannot agree on both, or conversely, cannot agree that both companies are equally culpable. This partial disagreement is common in multi-defendant cases and often reflects differing jury perceptions about which company bore primary responsibility or whose design practices were most clearly problematic. The inability to reach unanimity on one defendant, while potentially agreeing on another, keeps the jury in a stalemate.
What Does Judge Kuhl’s Action Mean for the Case if the Jury Remains Deadlocked?
Judge Kuhl issued what’s known as a deadlock admonition—a formal instruction reminding jurors of their duty to attempt to reach a verdict and encouraging continued deliberation. She also warned that if the jury remains unable to achieve unanimity, the case may require a partial retrial. A partial retrial would mean that the jury would be discharged, and a new jury would be empaneled to retry the case against whichever defendant the jury could not agree on. This is a significant development because it introduces the possibility that even after the current trial concludes, additional litigation may be necessary to reach a final verdict.
The prospect of a partial retrial presents both plaintiff and defendant considerations. For the plaintiff, a retrial is costly and time-consuming but may offer another opportunity to convince a jury of her claims. For Meta and YouTube, a retrial is also expensive and perpetuates legal uncertainty, but it avoids an unfavorable verdict if the current jury eventually deadlocks. Judges generally prefer to encourage continued deliberation and exhaust the possibility of unanimous agreement before declaring a mistrial, because retrials consume additional court resources and delay resolution. However, if the jury remains truly divided after further deliberation, Judge Kuhl would likely have no choice but to declare a mistrial on that defendant and schedule a new trial.
What Are the Key Legal Theories Driving This Case, and What Makes Them Difficult for Juries to Assess?
The lawsuit relies on several legal theories: product liability (claiming the social media platform is a defective product because its addictive design poses unreasonable risks), negligence (claiming the companies failed to exercise reasonable care in designing their platforms), consumer fraud (claiming misrepresentations about the harms of use), and statutory violations related to unfair or deceptive practices. Each theory requires the jury to find that the company either knew or should have known that its design practices would cause harm, that those harms were foreseeable, and that the company’s conduct failed to meet a reasonable standard of care. The difficulty lies in the tension between user choice and design manipulation.
Social media platforms argue that users choose to use their services and can choose to stop or limit use at any time. Plaintiffs counter that sophisticated, neuroscience-informed design practices override typical decision-making in ways analogous to how deceptive practices in other industries (tobacco, gambling, financial services) have been regulated. The jury must decide whether algorithm-driven recommendations and engagement mechanics constitute manipulation or merely optimization for user engagement—a philosophical distinction about which reasonable people can disagree. The fact that the jury has signaled difficulty suggests they are grappling sincerely with this distinction rather than reflexively accepting either the plaintiff’s or defendants’ framing.
How Did TikTok and Snap Navigate This Litigation Differently, and What Does That Mean?
TikTok and Snap both reached settlements with the plaintiff before trial commenced. These settlement agreements, while typically confidential, generally involve monetary payments to the plaintiff in exchange for dismissal of claims against those companies. By settling, TikTok and Snap avoided the uncertainty of a jury trial but also avoided the opportunity to establish a complete legal victory. Settlement can be strategically advantageous when the range of possible outcomes includes both substantial jury awards and the costs and management burden of trial.
The platforms’ legal teams apparently determined that the probability-weighted cost of trial exceeded the settlement amount they offered, or that a jury verdict against them would be damaging to their broader litigation posture in the hundreds of pending similar cases. The fact that two defendants chose to settle while two chose to proceed to trial may reflect differences in internal risk assessment, company culture, or the strength of evidence specific to each platform. Meta and YouTube may have believed their design practices were more defensible in court, or they may have wished to establish legal precedent clarifying that their practices do not constitute actionable harm. Alternatively, they may simply have calculated that a jury trial, despite its uncertainty, was preferable to the cumulative cost of settling this case plus negotiating settlements in hundreds of subsequent cases. The settlement decisions by TikTok and Snap have created an unusual trial dynamic where the remaining defendants are essentially trying to prevent a verdict that could accelerate liability findings against them in other pending litigation.
What Could This Case Mean for Future Social Media Regulation and Product Design?
If this jury returns a verdict finding Meta and YouTube liable for addictive design practices, it would establish a significant legal precedent that social media companies can be held accountable for harms arising from deliberately manipulative design. Such a verdict would likely trigger rapid settlement activity in hundreds of pending cases and could encourage legislative action to codify restrictions on certain engagement-maximization techniques or mandate transparency about algorithmic recommendation systems. Conversely, a defense verdict would suggest that current legal frameworks are insufficient to address social media design harms, potentially shifting attention toward legislative solutions or regulatory action by the Federal Trade Commission rather than private litigation.
The broader context includes increasing scrutiny of social media platforms from multiple directions: Congressional inquiries into the effects of social media on youth mental health, FTC enforcement actions against Meta for allegedly deceptive privacy practices, and state-level legislation like California’s age-verification laws. This jury’s decision, whatever it may be, will influence the trajectory of these parallel efforts. Even a hung jury on one defendant could signal to legislators that the existing private litigation framework creates uncertainty and delay, arguing for more direct regulatory intervention. The outcome of this case—or the uncertainty surrounding it, if the jury remains deadlocked—will likely accelerate discussions about how society wants to balance platform innovation and user engagement optimization against consumer protection.
