Plaintiffs still have individual cases because the social media addiction litigation is a mass tort, not a class action. Each family must still prove defective design, causation, and a specific injury, so bellwether trials only guide settlement value. There is no global personal-injury payout. The federal personal-injury cases are coordinated as MDL No.
3047 before Judge Yvonne Gonzalez Rogers in the Northern District of California for pretrial proceedings. The U.S. Judicial Panel on Multidistrict Litigation issued the coordination in a transfer order from the Panel. Individual, school-district, and attorney-general cases remain separate within that structure.

What this mass tort covers
This litigation groups claims that social platforms were defectively designed to addict adolescents. Defendants include Meta, Google, TikTok, and Snap. The claims focus on design features, not merely on posts by other users.
The Minnesota Attorney General reported a bipartisan coalition of 42 attorneys general sued Meta in October 2023. The suits allege Instagram and Facebook used features that purposefully addict children and teens. Related school-district claims and California coordinated cases proceed on parallel tracks for their own injuries and costs.
Why Section 230 did not end the cases
Judge Gonzalez Rogers denied dismissal motions in November 2023 for claims targeting addictive design features. Reuters reported the court held product-liability and negligence claims were not categorically barred by Section 230 or the First Amendment. The ruling kept design-defect theories alive for discovery and trial.
A Ninth Circuit panel then dismissed appeals by Meta, TikTok, Google, and Snap on Aug. 10, 2026. The Lanier Law Firm update on the decision reports the court treated Section 230 as a defense to liability rather than immunity from suit in its summary of the Ninth Circuit ruling. That holding allowed more than 3,000 individual, school-district, and attorney-general cases to proceed.

What each plaintiff must still prove
The court narrowed the litigation by dismissing some theories. Each plaintiff must still connect a specific product feature to personal harm. General concern about social media is not enough. The American Psychological Association identified features that make disengagement difficult, including like buttons, endless scrolling, autoplay video, push notifications, and AI recommendations.
The U.S. Surgeon General warned in May 2023 that adolescents spending over three hours daily face double the risk of depression and anxiety symptoms. Plaintiffs use that research as context, not as proof for any one child. A family claim generally needs three links:.
- defective design tied to particular features the child used
- causation connecting that use to the mental-health harm
- specific injury such as depression, eating disorders, or suicidal ideation
What the first bellwether verdict signals
A Los Angeles jury in California coordinated proceeding JCCP 5255 returned the first individual bellwether verdict in K.G.M. v. Meta and Google on March 25, 2026. LawyersTrend reporting on the Superior Court proceeding states the jury found negligent design caused addiction and awarded $6 million in its report on the bellwether verdict.
Liability was split 70 percent to Meta and 30 percent to Google. The verdict does not set payment for other families. Later plaintiffs must still present medical records, usage history, and expert testimony about design and causation. Families considering a claim should preserve account histories, device data, treatment records, and a timeline before contacting counsel.
