Opening arguments began Monday in a federal trial alleging Meta Platforms designed its social media apps to addict children [1].

The case centers on whether the parent company of Facebook and Instagram intentionally harmed the mental health of young users. A ruling against the company could establish new legal precedents for platform liability and child safety standards across the tech industry.

The trial is taking place in a U.S. District Court in California [2]. Attorneys general from several states said that Meta created addictive features to keep minors engaged while failing to disclose the associated mental health risks [1].

Reports on the scale of the litigation vary. Some sources said that four states are suing Meta in this specific action [1], while other reporting indicates as many as 29 states are involved in legal challenges against the company [4].

Meta is currently facing thousands of child-safety lawsuits [4]. The company has already lost two child-safety trials and settled a third [5].

The financial stakes are significant. Some estimates suggest Meta's potential liability could reach $1.4 trillion [4].

Meta has denied the allegations. The company said that its platforms provide value to users and that it implements safety measures to protect minors.

Meta Faces Federal Trial Over Alleged Child Social Media Addiction

This trial represents a critical test of whether social media algorithms can be legally classified as defective products. If the court finds that Meta intentionally engineered addiction, it could open the door for massive systemic damages and force a fundamental redesign of how platforms interact with minors.
