Meta Found Liable for Social Media Addiction: $6M Verdict Upheld

In March 2026, a California jury delivered the first verdict in a social media addiction lawsuit, ordering Meta and Google to pay $6 million to a young woman who said Instagram and YouTube were designed to hook her as a child. The case, K.G.M. v. Meta Platforms, Inc., was the first of thousands of similar suits to reach a jury, and the panel found both companies negligent, defectively designed, and acting with malice.

What the Jury Decided

On March 25, 2026, after deliberations that began on March 13, twelve jurors in Los Angeles Superior Court found that Instagram and YouTube were defectively designed to be addictive and that the design was a “substantial factor” in causing the plaintiff’s harm.¹ The specific features the jury identified included infinite scroll, algorithmic recommendations, autoplay, constant notifications, and beauty filters. The established harms were depression, anxiety, body dysmorphia, and suicidal thoughts.²

The jury also found that Meta and Google acted with “malice, oppression, or fraud,” the finding required under California law to award punitive damages.³

The $6 million total broke down as follows:

$3 million in compensatory damages
$3 million in punitive damages

Liability was split 70 percent to Meta ($4.2 million) and 30 percent to Google ($1.8 million).²

The Legal Theory That Made It Possible

Social media companies have long relied on Section 230 of the Communications Decency Act, which shields platforms from liability for what users post. The plaintiff’s lawyers steered clear of that shield. They did not sue over content. They sued over the product itself, arguing that features like infinite scroll, autoplay, algorithmic recommendations, push notifications, and beauty filters were engineered to maximize time on the app and foreseeably harmed developing brains. Lead counsel Mark Lanier compared the platforms to a “digital casino.”¹

The design-versus-content distinction had already cleared major pretrial hurdles. In September 2025, Judge Carolyn B. Kuhl issued an 87-page ruling that Section 230 did not bar the plaintiffs’ claims because their expert testimony focused on platform design rather than content.⁴ In the parallel federal multidistrict litigation, Judge Yvonne Gonzalez Rogers had reached a similar conclusion, letting claims for defective design, failure to warn, inadequate age verification, and weak parental controls proceed.⁵

The Plaintiff

The plaintiff, identified in court records as K.G.M. and known publicly as Kaley, started watching YouTube at age six and joined Instagram at nine. At her peak, she spent more than 16 hours on Instagram in a single day. She testified that notifications gave her a “rush,” that she left class to check them, and that she created multiple accounts and bought likes to appear popular. She said her attempts to set limits never held: “Anytime I tried to set limits for myself, it wouldn’t work and I just couldn’t get off.”⁶

Nearly all of the photos she posted used filters to alter her appearance, and she testified that she did not have the feelings associated with her body dysmorphia diagnosis before she began using social media and those filters.⁶ Her lawyers presented evidence that she avoided telling her therapist about her social media use out of fear that her parents would take her phone away.⁷

What Meta’s Executives Said on the Stand

Mark Zuckerberg testified on February 18, 2026, his first time addressing child safety allegations before a jury. Lanier confronted him with internal Meta documents, including a 2018 strategy memo stating: “If we wanna win big with teens, we must bring them in as tweens.” Another document from 2020 showed that 11-year-olds were four times more likely to return to Meta’s apps than older users.⁸

Asked about internal research showing beauty filters worsened body-image problems, Zuckerberg said removing them would be “paternalistic,” and that Meta had opted to keep the filters but not recommend them.⁸ Pressed on the estimate that four million children under 13 used Instagram despite the platform’s stated age requirement, Zuckerberg acknowledged that enforcing age restrictions is “very difficult.”⁹

Instagram head Adam Mosseri had testified a week earlier. Asked about Kaley’s 16-hour days on the app, he called it “problematic use” but refused to call it addiction, comparing the behavior to watching too much television and saying he was not qualified to draw the medical line.¹⁰ Lanier also introduced an internal Meta survey in which 60 percent of roughly 269,000 respondents said they had experienced or witnessed bullying on the platform in the previous week. Mosseri testified he was unaware Kaley had filed more than 300 bullying reports.¹¹

How Meta and Google Defended the Case

Meta and Google argued that complex mental health issues cannot be traced to a single app, and that the companies were being used as a “scapegoat” for problems with many causes. Defense lawyers pointed to medical records indicating Kaley had experienced emotional and physical abuse at home, and noted that none of her therapists had documented social media as a factor in her mental health struggles.¹

Google took a separate line, arguing that YouTube was being mischaracterized as social media at all. A Google spokesperson described it as “a responsibly built streaming platform, not a social media site.”³ Both companies maintained there was no scientific proof linking social media use to mental health harm.¹

The Verdict Held Up in Post-Trial Motions

In May 2026, Meta and Google asked Judge Kuhl to overturn the verdict or order a new trial, arguing it violated Section 230 and the First Amendment.¹²

On June 10, 2026, Judge Kuhl denied both motions. In her ruling, she wrote that Section 230 “does not address the companies’ design choices” and that “there was substantial evidence that Plaintiff was harmed by the design features of Instagram, regardless of any of the content found on that platform.” She noted that jurors had been “repeatedly instructed not to consider content” during deliberations.¹³

Both companies said they will appeal to a California appellate court. Meta called the plaintiffs’ theory an attempt to “improperly circumvent Section 230 and the First Amendment.”¹³

Why This Verdict Matters Beyond $6 Million

The dollar figure is small compared to what is coming. K.G.M. was a bellwether, one of three test cases selected from California’s coordinated proceeding (JCCP 5255) to give both sides real data on how juries receive the evidence. Bellwether outcomes set benchmarks for damages and drive settlement pressure across the broader pool.

That pool is large. The federal multidistrict litigation, In re Social Media Adolescent Addiction/Personal Injury Products Liability Litigation, MDL No. 3047, in the Northern District of California, now encompasses more than 10,000 individual cases and nearly 800 school district claims.¹⁴ Federal bellwether trials in that MDL, including six school district cases and five individual cases, are expected to begin in late 2026.¹⁵

Two things will decide where the litigation goes from here. The first is whether federal juries hearing the same defective-design arguments reach the same conclusion this California jury did. The second is whether the appellate courts accept the design-versus-content line that let plaintiffs get past Section 230 at trial. If both hold, the industry is looking at either a global settlement or years more of litigation on the same theory. If the appeals succeed, the K.G.M. verdict may not survive to guide anything.
