Meta and YouTube Just Lost Their First Big Social Media Trial

On March 25, 2026, a Los Angeles jury delivered a verdict that advocates had been waiting years to see. After more than eight days of deliberation and a seven-week trial, jurors found Meta and Google’s YouTube negligent in the design of their platforms — deliberately built to be addictive, the jury concluded, in ways that caused measurable harm to a young user. The jury awarded a total of $6 million in damages, split equally between $3 million in compensatory damages and $3 million in punitive damages. Meta bears 70 percent of the liability; Google the remaining 30.

The decision did not arrive in a vacuum. One day earlier, a separate jury in New Mexico had ordered Meta to pay $375 million after finding the company misled users about the safety of its platforms and failed to protect young users from predatory behavior on Instagram and Facebook. Two verdicts, two states, two days. The legal landscape for social media companies shifted visibly.

Who the Case Was About

The plaintiff, a now-20-year-old California woman identified in court documents only by her initials KGM and referred to publicly as Kaley, began using YouTube at age six and Instagram at age nine. By the time she finished elementary school, she had posted nearly 300 videos on YouTube. She told the court she stopped engaging with family because she was spending all her time on social media, and that she began suffering anxiety and depression at age ten. She was later diagnosed with both, along with body dysmorphia — a condition she said developed directly from her social media use.

Kaley was in the courtroom when the verdict was read. Her attorneys called it a historic moment. “A jury of Kaley’s peers heard the evidence, heard what Meta and YouTube knew and when they knew it, and held them accountable,” they said in a statement reported by CNN.

What the Internal Documents Showed

The verdict validated a legal strategy built not around the content users see on social media, but around how the platforms were designed. Plaintiff attorneys introduced internal Meta documents during the trial that made for striking reading. One memo described the company’s goal of attracting users as tweens, noting that 11-year-olds were four times as likely to keep returning to Instagram compared to competing apps — despite the platform’s stated minimum age of 13. Another document, attributed to CEO Mark Zuckerberg, outlined efforts to attract and retain young users on the platforms.

The jury found that Meta had been negligent in designing and operating Instagram, and that this negligence was a substantial factor in Kaley’s harm. Google was found negligent in the design and operation of YouTube on the same grounds. Both companies said they disagreed with the verdict and planned to appeal. “This case misunderstands YouTube, which is a responsibly built streaming platform, not a social media site,” a Google spokesperson said.

What Comes Next

The Los Angeles case was selected as a bellwether — a test case chosen to help determine outcomes in similar consolidated litigation across California. Attorneys involved in the broader litigation against social media companies drew immediate comparisons to the legal campaign against Big Tobacco in the 1990s, which ultimately forced an industry-wide reckoning over the targeting of minors.

More than 2,000 pending cases involving similar claims now await resolution, and a federal trial involving school districts and parents nationwide is scheduled to begin later in 2026. TikTok and Snap, originally defendants in the Los Angeles case, settled with Kaley before the trial began and remain involved in separate proceedings. The Los Angeles verdict does not bind those cases, but it signals to defendants and plaintiffs alike that juries are willing to hold platforms accountable.

A Cultural Reckoning in Real Time

The trial unfolded against a backdrop of years of public debate about what social media platforms have done to a generation of young people. Parents, educators, pediatricians, and lawmakers have raised alarms about the mental health toll of these apps on children and adolescents. The platforms have consistently argued that correlation does not equal causation, and that complex mental health outcomes cannot be attributed to app design.

The Los Angeles jury disagreed. The judge retains final authority over the damages amount before a formal judgement is entered. Whether the verdict holds through that process and any subsequent appeal remains to be seen — but its weight extends beyond the courtroom. It names what many have long argued: that these platforms were not passive hosts of content, but active architects of behavior. In 2026, a jury put that argument in writing.
