No verdict has been announced yet in the landmark social media addiction trial currently captivating the legal world. As of late March 2026, a jury of 12 is deliberating in Los Angeles Superior Court in the case known as KGM v. Meta & YouTube—a bellwether trial that could reshape how social media companies operate. The jury began private deliberations around March 21, 2026, following closing arguments delivered just days earlier on March 12. A verdict is expected sometime in spring or summer 2026, but the exact timeline remains uncertain as jurors work through one of the most complex and consequential cases involving technology companies in recent years.
This trial represents far more than a single case. At stake is whether Meta, YouTube, and other social media platforms intentionally designed their products to maximize addictive engagement in ways that harmed young people. A 20-year-old woman brought the case, claiming social media addiction caused her psychological and emotional damage. Her lawyers presented approximately one month of testimony from addiction experts, therapists, platform engineers, and company executives. The defense then presented their own witnesses before resting on March 11. This article explains what happened during the trial, what the jury must now decide, and why the outcome could affect more than 10,000 other cases nationwide.

What Is Happening in the Jury Deliberations Right Now?
The jury is working through what may be the most complex evidence presented in any recent technology litigation. Over roughly six weeks of proceedings, jurors heard from dozens of witnesses—addiction experts explaining how social media can rewire the adolescent brain, former platform engineers describing how algorithmic systems are built to maximize engagement, and company executives defending their design choices. Now, in closed-door deliberations, the jury must answer a central question: did Meta, YouTube, TikTok, and Snapchat knowingly design features intended to addict young users? The jury’s job is to determine liability—whether the platforms are legally responsible for the harm alleged. This is different from calculating damages; that would come later if the defendants are found liable. The deliberation process typically involves jurors reviewing evidence, discussing competing arguments, and trying to reach unanimous agreement on the facts.
Given the complexity of the case, deliberations could take weeks rather than days. No verdict timeline has been publicly confirmed, but spring 2026 or summer 2026 remains the expected window. One important limitation to understand: this trial will not be the final word on social media addiction. Even if the jury rules in favor of the plaintiff, appeals will follow. The defendants have already signaled they will challenge any adverse verdict. This case is the first of several planned trials; Judge Rogers has already scheduled additional bellwether trials for June 15 and August 6, 2026, to test different theories and assess damages.
What Evidence Did Experts Present About Platform Design and Addiction?
During the evidence phase, the plaintiff’s team presented detailed testimony about how social media platforms employ addictive design patterns. Expert witnesses explained that endless scrolling feeds, algorithmically generated content recommendations, notification systems, and reward mechanics (like likes and shares) are deliberately engineered to keep users engaged as long as possible. The comparison to gambling addiction kept recurring in testimony—both exploit psychological vulnerabilities through variable rewards and intermittent reinforcement. Mark Zuckerberg himself took the stand on February 18, 2026, marking his first-ever testimony before a jury. His presence underscored the case’s significance. During his testimony, Zuckerberg faced questions about meta‘s design philosophy, internal documents about engagement metrics, and whether the company prioritized user well-being over engagement.
Documents presented to the jury included internal communications where Meta executives discussed the addictive nature of their platforms. However, Zuckerberg and other Meta leaders defended their design choices as efforts to create engaging products that users voluntarily use. The defense rested their case on March 11 after presenting ten witnesses. Meta and YouTube’s defense centered on the argument that users choose to spend time on their platforms, that social media use is not addiction in the clinical sense, and that the companies have implemented numerous safeguards for young users. However, if the jury believes the evidence that these platforms were designed specifically to exploit vulnerabilities in young people, the defense argument that use is merely “voluntary choice” loses much of its weight. The question before the jury is whether informed choice is even possible when a platform’s design is specifically engineered to manipulate behavior.
How Many People Could Be Impacted by This Trial’s Outcome?
The scale of this litigation extends far beyond the single plaintiff and her family. According to court filings, at least 2,407 claims are currently pending in the Multidistrict Litigation (MDL)—a consolidation of related cases handled in one court for efficiency. But the full scope is even larger: more than 10,000 individual cases involving social media addiction have been filed nationwide. Additionally, nearly 800 school districts have joined claims alleging that social media addiction has disrupted student learning and increased mental health crises in their schools. This means that if the jury returns a verdict finding Meta, YouTube, or other defendants liable, the outcome could establish legal precedent that applies to thousands of pending cases.
Plaintiffs’ attorneys could use a favorable verdict to settle cases en masse, or to convince other juries in different jurisdictions that the companies’ conduct was wrongful. Conversely, if the jury rules in favor of the defendants, it strengthens the legal position of these companies in the thousands of other cases still pending. The school district claims present a distinct issue. Schools argue they have incurred costs—for counseling services, mental health staff, security measures, and lost instructional time—specifically because social media addiction has affected their student populations. However, the school district claims face a different legal threshold than individual plaintiffs; they must prove not only that the platforms are addictive but also that the schools’ specific costs directly resulted from platform design rather than other factors affecting adolescent mental health.
What Are the Possible Outcomes and Their Consequences?
If the jury finds the defendants liable, the case would move into a damages phase, where another jury (or the same jury) would decide how much money the defendants owe to the plaintiff and potentially to a class of similarly affected users. Damages could be calculated on a per-user basis, which would create massive exposure for Meta and YouTube. A verdict against the defendants would likely trigger a wave of settlement negotiations for the thousands of pending cases. Conversely, if the jury finds in favor of the defendants, it sends a powerful signal that the current legal system does not hold social media platforms accountable for addiction-related harms. This would substantially weaken the cases of the remaining 10,000 plaintiffs. However, plaintiffs’ attorneys would likely appeal an unfavorable verdict and could pursue different legal theories in future cases.
Additionally, plaintiffs could argue that subsequent trials reveal facts not presented in this first bellwether trial—a common strategy in mass litigation. Judge Rogers has already scheduled two additional bellwether trials for June 15 and August 6, 2026. These are not trials of different cases entirely, but rather tests of different claims or fact patterns within the MDL. The strategic purpose is to gather information about how juries respond to various evidence presentations and legal arguments. If this trial’s outcome is favorable to plaintiffs, the June and August trials might present even stronger cases. If this trial’s outcome is unfavorable, the plaintiffs’ team might refine their approach for subsequent trials.
What Specific Design Features Are at the Heart of This Case?
The trial evidence focused heavily on three categories of platform design features that allegedly drive addictive behavior. First, algorithmically generated endless feeds: rather than showing users posts only from accounts they follow, platforms use algorithms to populate feeds with engaging content designed to keep users scrolling indefinitely. This is fundamentally different from a traditional social network where users decide what to view. Second, reward systems: likes, shares, comments, and follower counts create immediate social validation feedback loops. Every time a user posts, they receive notifications about engagement metrics.
This creates what behavioral psychologists call “variable ratio reinforcement”—an unpredictable reward schedule that is known to be more habit-forming than predictable rewards. Young users, whose brains are still developing in the prefrontal cortex (the region governing impulse control and decision-making), are particularly vulnerable to this mechanism. Third, notification systems: platforms send incessant notifications—messages, alerts about likes, reminders to return to the app, notifications about what friends are doing—designed to pull users back into the application repeatedly throughout the day. Testimony revealed that Meta and YouTube have internal teams dedicated to optimizing these notification systems for maximum re-engagement. However, the defendants argued that users can disable notifications and that they have provided parental controls and time-limit features to help manage usage. The jury must weigh whether the existence of these tools is sufficient protection if the overall product design actively works against them.
Who Is the Plaintiff and What Brought This Case?
The case is being brought by a 20-year-old woman whose identity is protected in court filings (referred to as KGM). She alleges that her heavy use of social media during her teenage years caused her addiction, psychological distress, and emotional harm. Her complaint is that Meta, YouTube, TikTok, and Snapchat knew their platforms were addictive and deliberately designed them that way—prioritizing engagement and advertising revenue over user well-being, particularly for young people. This individual case is representative of a broader category of claims brought by families and young people nationwide.
Some plaintiffs are parents suing on behalf of minor children. Others are young adults, like the plaintiff in this trial, alleging that their formative teenage years were shaped by addiction to social media. The commonality across all claims is the allegation that platform design—not mere platform availability—is the cause of harm. In other words, plaintiffs are not arguing that social media simply exists and people overuse it; they are arguing that the platforms were architecturally engineered to create addiction.
What Comes Next as the Legal Process Continues?
The immediate focus is on the jury’s verdict, expected spring or summer 2026. Once the jury returns a decision, both sides will likely have motions to file—the losing side challenging the verdict, both sides advocating for specific remedies. If the jury finds liability, a second phase will determine damages. If the jury rules for the defendants, appeals will begin.
Beyond this first trial, the June 15 and August 6, 2026 bellwether trials will test different aspects of social media addiction claims. These subsequent trials may involve different defendants (TikTok and Snapchat have already settled their portions of the case, removing them from this and future trials), different types of harm (mental health diagnoses versus educational impacts), or different age groups. The outcomes of all three bellwether trials combined will give both plaintiffs and defendants crucial information about how courts and juries view these claims. This information will likely drive settlement negotiations for the thousands of remaining cases. Whether this turns into a settlement landscape comparable to other mass torts—like tobacco litigation or opioid litigation—depends heavily on whether plaintiffs can win verdicts or secure favorable settlements early.
