The K.G.M. v. Meta & YouTube trial in Los Angeles Superior Court has reached a critical juncture—there is no final ruling yet, and as of March 25, 2026, jurors are in their eighth day of deliberations with growing signs of potential deadlock on at least one defendant.
This landmark case, brought by a 20-year-old from Chico, California, alleges that Meta and YouTube deliberately engineered addictive features causing significant mental health harm. The lack of a verdict so far signals that the questions at stake in this case—how social media companies are legally responsible for addiction-related injuries—are far more complex than either side may have anticipated during closing arguments on March 12, 2026. If you’ve been affected by social media addiction or have concerns about pending litigation, understanding where this trial stands and what happens next is essential context for your own potential claims.

Where Is the K.G.M. Trial Now? Current Jury Deliberations and Deadlock Risks
jury deliberations began on March 13, 2026, just one day after closing arguments wrapped up on March 12. As of late March 2026, jurors have been deliberating for eight days, a timeframe that suggests they are grappling with complex liability questions and potential damages. According to reports from Fox 11 Los Angeles and NBC Los Angeles, there are growing signs that at least one defendant—most likely YouTube—may be facing potential deadlock among jurors. Judge Carolyn B.
Kuhl has warned that if the jury cannot reach a consensus on one defendant, the court may need to declare a mistrial on that defendant alone, which would trigger a partial retrial specifically for that party. The fact that jurors have requested information about compensatory damages in recent weeks suggests that they may have already reached liability conclusions on at least one defendant. Jurors asking about damages is a strong indicator that they believe someone should be held responsible, but they’re now determining the financial scope of that responsibility. This is a critical distinction: some jurors may be voting to hold meta liable while others push for YouTube liability or split the responsibility differently, preventing full consensus.
Understanding the Claims Against Meta and YouTube
Plaintiff K.G.M., represented by attorneys specializing in product liability and consumer protection, alleges that both Meta (which owns Instagram and Facebook) and YouTube used what the case describes as “engineered addiction” features to harm her mental health. The defendant companies rested their case on March 11, 2026, after calling ten witnesses who presumably challenged the causation link between social media features and mental health injury. This is important to understand: Meta and YouTube don’t dispute that social media can affect mood or behavior, but they likely argued that there’s insufficient evidence that their design choices—like infinite scroll, algorithmic recommendations, or notification systems—were specifically intended to cause the psychological damage K.G.M.
Claims. However, internal Meta documents (including the now-famous “Facebook Papers”) have shown that the company conducted internal research on the mental health effects of its platforms, particularly Instagram, and chose not to alter certain features despite knowing the risks. This pattern of knowledge-plus-inaction is precisely what product liability cases hinge on: did these companies know about a serious risk and fail to warn consumers or redesign their products to reduce that risk? K.G.M.’s case must prove that Meta and YouTube’s conduct fell below the standard of reasonable care, which is the legal threshold for negligence and design defect claims.
The Broader Landscape—4,000+ Pending Cases and Multiple Defendants
K.G.M. v. Meta & YouTube is the first bellwether trial among hundreds of similar lawsuits still pending nationwide. Approximately 4,000 cases overall have been filed against social media companies alleging addiction-related harms, and roughly 2,407 claims are consolidated in multidistrict litigation (MDL 3047). A bellwether trial is essentially a test case: its outcome will heavily influence how the remaining cases settle or proceed. If K.G.M.
Wins a significant damages award, expect a flood of settlement negotiations and possibly class certification motions in the pending claims. If she loses, many other claimants may drop their cases or see their settlements values plummet. Not all social media platforms have remained as aggressive in their defense. TikTok and Snapchat have already settled their claims before trial, signaling that those companies chose to avoid the risk and expense of jury litigation. Meta and YouTube, by contrast, have fought through the trial process, which reflects their confidence in their legal position or their belief that settling would create costly precedent for the hundreds of other pending claims. This defense strategy has real consequences: the longer Meta and YouTube litigate, the more legal fees accrue, and the more time passes for other potential claimants to file or pursue their own cases.
What Happens If the Jury Deadlocks or Reaches a Verdict?
If jurors cannot reach a unanimous decision on one or both defendants, Judge Carolyn B. Kuhl will likely declare a mistrial (or a partial mistrial) for the defendant or defendants on which consensus broke down. This would not mean either side “won”—it would simply mean the trial is abandoned and the case may be retried with a new jury, potentially with adjusted claims or settlement discussions. A partial mistrial for YouTube (while Meta receives a verdict) is possible; this scenario would reflect different jury conclusions about each defendant’s conduct and liability.
If jurors do reach a verdict and find at least one defendant liable, the remaining question is the damages amount. Product liability cases involving emotional distress and mental health claims can result in significant compensatory damages (medical treatment costs, therapy expenses, lost wages if the plaintiff couldn’t work) plus potential punitive damages (meant to punish companies for reckless conduct). Compare this to a verdict of “not guilty,” where no damages are awarded and the defendant walks away legally vindicated. A partial verdict—Meta liable but YouTube not liable, or vice versa—is also possible and would set different precedent for each company’s future litigation.
Meta’s Insurance Dispute and Defense Challenges
A complicating factor in this case emerged on March 3, 2026, when a Delaware judge ruled that Meta’s liability insurers are not obligated to provide a defense for the addiction-related claims. Meta has 30 days from that ruling to appeal the decision, but the implication is significant: Meta may be bearing the full cost of its legal defense without insurance coverage reimbursement. This is unusual in product liability cases, where companies typically rely on their commercial general liability or product liability insurance to cover defense costs and damages.
The reason for this insurance denial is that Meta’s policies were likely written with exclusions or limitations for “advertising” or “media” related claims, and insurers have argued that social media platform design and algorithmic amplification don’t fit within the coverage. This means Meta is in a high-stakes situation: a large damages verdict would come directly from its corporate coffers, not from an insurer. Additionally, on March 17, attorneys threatened sanctions against Meta for producing 73,841 documents late in the litigation, suggesting Meta’s legal team has struggled with the volume and complexity of discovery. These procedural missteps can damage jury perception and indicate a company that is not operating transparently.
What This Trial Means for Your Own Potential Claim
If you or a family member has experienced mental health challenges related to social media use, K.G.M. v. Meta & YouTube is the foundational case that could determine whether you have a viable claim. The trial is not a class action lawsuit—K.G.M. is an individual plaintiff—but the verdict (or lack thereof) will directly influence settlements and legal strategy for the 4,000+ other cases filed nationwide.
In multidistrict litigation (MDL 3047), a bellwether verdict often triggers settlement discussions, as companies and plaintiffs’ attorneys use the outcome to value the remaining claims. More importantly, a K.G.M. victory would strengthen your legal position if you ever file your own claim. Courts and insurers use bellwether results to adjust settlement ranges; a jury finding that Meta or YouTube engaged in “engineered addiction” and caused mental health injury would establish that this type of harm is legally cognizable (provable in court). Conversely, a defense verdict would make future claims harder to pursue and settle for lower amounts.
The Future of Social Media Addiction Litigation
Regardless of the K.G.M. verdict, social media addiction litigation is likely to continue evolving. Legislative efforts in Congress have stalled on comprehensive social media regulation, which means the civil court system remains the primary venue where companies can be held accountable for platform design choices. Federal law and state consumer protection laws, combined with product liability doctrine, give plaintiffs tools to challenge social media companies, but the legal bar for proving “engineered addiction” and causation is high.
State attorneys general have also filed separate claims alleging that social media companies unfairly target minors and create addictive environments. These regulatory actions, while different from the K.G.M. civil case, contribute to the broader legal pressure on Meta, YouTube, TikTok, and Snapchat. As regulations evolve and more bellwether trials conclude, we can expect either greater settlement activity or clearer jury guidance on how courts will value addiction-related mental health claims going forward.
