The jury in a landmark social media addiction trial in Los Angeles has been deliberating for over eight days as of late March 2026, with jurors reporting difficulty reaching consensus on at least one of the two defendants. Judge Carolyn B. Kuhl, presiding over the case in downtown Los Angeles Superior Court, warned that if the jury deadlocks on either defendant, that portion of the case would need to be retried—a significant outcome that could reshape how platforms face accountability for addiction-related harms.
The case centers on K.G.M., a 20-year-old plaintiff from Chico, California, who alleges that Meta and YouTube (owned by Google) deliberately engineered their platforms with addictive features that targeted her during her teenage years and contributed to serious mental health damage. This trial represents one of the first major cases to go to verdict in the wave of social media addiction litigation that has swept across the country in recent years. The case is notable not just for its legal claims but because two major defendants—TikTok and Snap—chose to settle before trial even began, while Meta and YouTube decided to fight the case in court.

How Long Have Jury Deliberations Been Underway in This Social Media Addiction Trial?
The jury began deliberations on March 13, 2026, meaning that as of late March, they had been wrestling with the evidence and legal instructions for more than eight days. This extended deliberation period is not unusual in complex cases involving multiple defendants and competing narratives, but it does signal that jurors are taking the case seriously and are not rushing to judgment. The trial itself spanned approximately one month, during which testimony covered Meta’s and YouTube’s product design practices, internal documents about user engagement algorithms, expert testimony about the addictive nature of social media, and evidence about the plaintiff’s personal experience with these platforms.
The length of deliberations often reflects the difficulty of the legal and factual questions at hand. In this case, jurors must weigh whether the platforms’ design features constitute an “engineered addiction” under California law, whether those practices directly caused the plaintiff’s alleged harms, and whether the defendants are legally responsible for her mental health struggles. By March 24, 2026, the jury’s slow progress had become visible to observers, with judge’s inquiries revealing that consensus was proving elusive on at least one defendant—a sign that jurors may be split on liability, damages, or both.
What Are the Key Allegations Against Meta and YouTube in This Case?
The plaintiff’s legal team argues that meta (owner of Facebook and Instagram) and YouTube deliberately designed their platforms using psychological principles and algorithmic features specifically intended to maximize user engagement and time spent on the services, with full knowledge that such designs would be particularly addictive to young users. The core claim is not simply that the platforms are engaging—it’s that the companies made calculated choices to create addiction-like patterns of use, similar to how tobacco companies designed cigarettes for maximum addictiveness. During the trial, the plaintiff’s lawyers presented internal Meta and YouTube documents, algorithms, and testimony from former employees and addiction experts to support this narrative.
However, a critical limitation of addiction liability cases is that they require proving not just that a product is habit-forming, but that the company knew it would cause specific harm to the individual plaintiff and proceeded anyway. The plaintiff must show a direct causal chain between the platform’s design features and her personal mental health injuries—depression, anxiety, or other documented conditions. This is more difficult than proving a general risk; it requires tying the defendant’s behavior to this particular 20-year-old’s suffering, which is where the defense’s counterargument becomes relevant.
What Is the Defense Argument in This Social Media Addiction Trial?
Meta and YouTube’s legal teams have argued that the plaintiff’s mental health problems and addictive social media use stem primarily from her home life, family dynamics, and personal circumstances rather than from the platforms’ design. This defense strategy shifts focus away from what the companies built and toward the plaintiff’s own environment and vulnerabilities.
The defense suggests that even if the platforms are engaging, thousands of other young people use them without experiencing the same level of harm, and that the plaintiff’s particular struggles cannot be attributed to Meta or YouTube’s design choices. This argument touches on a broader tension in addiction liability: where is the line between a company’s responsibility for designing a compelling product and an individual’s responsibility for their own choices and personal circumstances? The defense essentially contends that the plaintiff’s case is not about social media addiction as a general phenomenon, but about her specific situation—and her home life, not platform design, is the determining factor in that situation. The jury must decide whether this explanation is persuasive or whether the plaintiff has proven that Meta and YouTube’s deliberate design choices were the primary cause of her harms.
Why Did TikTok and Snap Settle Before Trial While Meta and YouTube Proceeded to Court?
Before the trial began, both TikTok and Snap reached settlement agreements with the plaintiff and exited the case entirely. The exact terms of those settlements were not publicly disclosed, but their decision to settle before trial suggests that the companies evaluated the legal risk, the strength of the plaintiff’s evidence, and the potential liability exposure and decided that negotiated settlement was preferable to the uncertainty and expense of a full jury trial. Settlement before trial is common in civil cases and often reflects a strategic calculation rather than an admission of guilt. Meta and YouTube, by contrast, chose to defend the case fully in court.
This decision carries both risks and potential rewards. If they lose, the verdict could expose them to larger damages awards and establish precedent that could fuel hundreds of similar cases across the country. If they win, they send a message that social media addiction claims are legally insufficient and may protect them from broader liability exposure. The fact that two defendants settled while two proceeded to trial illustrates the strategic complexity of these cases and the different risk calculations that even similarly situated companies may make.
What Does a Jury Deadlock Mean for This Case and Future Litigation?
A jury deadlock occurs when jurors cannot reach the unanimous verdict required in most civil trials. If the jury deadlocks on Meta (meaning some jurors vote for liability and damages while others vote for the defendant), then the case as to Meta would be declared a mistrial and would need to be retried from scratch—new jury selection, new trial, new evidence presentation. The same applies if the jury deadlocks on YouTube. Judge Kuhl explicitly warned that if a deadlock occurs on either defendant, “at least partial” retrial would be necessary.
This is a significant procedural outcome that benefits neither side: the plaintiff does not get a final judgment, the defendants do not get final closure, and the entire process must begin again. A critical limitation of deadlock outcomes is that they do not resolve anything and create enormous uncertainty. They consume judicial resources, extend litigation timelines by months or years, and leave all parties unable to move forward. However, if a jury deadlocks after extensive deliberation, it often signals that the evidence was genuinely ambiguous or that the legal theory itself is problematic—information that could influence how future similar cases are litigated. As of late March 2026, the jury was still working toward a decision, but the judge’s warnings suggested that deadlock was a real possibility.
What Do the Jury’s Reported Difficulties Tell Us About This Case?
On March 24, 2026, jurors communicated to the judge that they were struggling to reach consensus, specifically reporting difficulty with respect to one of the two defendants. This communication suggests that the jury may have reached agreement on one defendant but remained deadlocked on the other, or that jurors were deeply divided on the core questions of liability and causation. In some cases, juries struggle with a particular defendant because the evidence regarding that defendant was weaker or more ambiguous, or because jurors interpreted the legal instructions differently as applied to that company.
The fact that jurors felt comfortable communicating their struggle to the judge indicates a fair and transparent jury process. Judges often receive these reports and may provide clarifying instructions, ask jurors to continue deliberating, or in some cases accept a partial verdict if some defendants have consensus while others do not. The outcome of that judge-jury dialogue would determine whether deliberations continued or whether the case was partially or fully resolved.
What Is the Broader Significance of This Landmark Social Media Addiction Trial?
This case is part of a larger wave of litigation attempting to hold social media platforms accountable for alleged addictive design practices and mental health harms. Unlike product liability cases involving physical injury or traditional consumer fraud, these cases require courts and juries to grapple with novel questions about psychological manipulation, algorithmic design, and corporate responsibility for behavioral harms. A verdict—whether for or against the plaintiff—will provide important guidance on whether such claims are legally viable under existing law or whether new legislation is needed.
The outcome will also influence how TikTok, YouTube, Meta, and other platforms develop their services going forward. If the jury returns a verdict for the plaintiff with substantial damages, platforms may face pressure to redesign features, reduce algorithmic recommendations, and add friction to their services—changes that could fundamentally alter how billions of people interact with these tools. Conversely, if the jury sides with the defendants, it may signal that social media addiction claims lack legal merit and that the burden of managing social media use rests primarily with individuals and families rather than with platforms themselves.
