Meta liable for teen harm, will appeal

Meta Platforms Inc. was found liable in two separate U.S. court decisions last week tied to the safety and mental health of teenage users, according to the rulings described in the cases.

In the first decision, a court in New Mexico ruled against Meta on March 24, 2026 , finding the company violated the state’s Unfair Practices Act . Officials described the outcome as the first time Meta has been held legally accountable for endangering child safety. The judgment imposed a $375 million fine, calculated using a maximum penalty of $5,000 per violation .

A day later, a jury in Los Angeles found Meta and YouTube negligent for designing addictive product features that harmed a 20-year-old plaintiff. In that case, the jury assigned 70% of liability to Meta and 30% to YouTube. The verdict resulted in a combined fine of $6 million , based on the allocation of responsibility described in the judgment.

Together, the two outcomes are being closely watched because they center on platform design choices—such as endless scrolling and constant notifications —rather than focusing on user-generated posts. The distinction matters in U.S. litigation because user content is typically shielded under Section 230 of U.S. law, while the cases described here emphasize product features and how they are built and presented to users.

The decisions are expected to shape the trajectory of a large volume of related litigation. The verdicts were described as likely to influence thousands of pending lawsuits involving Meta, including cases filed by 40 state attorneys general . While the penalties in the two cases were characterized as relatively small compared with Meta’s overall scale, the source material notes that the cumulative exposure could grow if similar claims succeed across many jurisdictions and plaintiffs.

Meta said it disagrees with the outcomes and intends to appeal . The timing and results of those appeals remain uncertain, and the longer-term legal impact will depend on how higher courts treat the underlying theories of liability focused on product design rather than user content.
