A New Mexico jury ruled Tuesday that Meta knowingly harmed children's mental health and concealed what it knew about child sexual exploitation on its social media platforms.

The landmark decision comes after a nearly seven-week trial, and as jurors in a federal court in California have been sequestered in deliberations for more than a week about whether Meta and YouTube should be liable in a similar case.

Jurors sided with state prosecutors who argued that Meta — which owns Instagram, Facebook and WhatsApp — prioritized profits over safety. The jury determined Meta violated parts of the state's Unfair Practices Act on accusations the company hid what it knew about about the dangers of child sexual exploitation on its platforms and impacts on child mental health.

The jury agreed with allegations that Meta made false or misleading statements and also agreed that Meta engaged in "unconscionable" trade practices that unfairly took advantage of the vulnerabilities of and inexperience of children.

Jurors found there were thousands of violations, each counting separately toward a penalty of $375 million.
