The social media addiction lawsuit is a wave of product liability litigation accusing Meta, Google, TikTok, and Snap of deliberately designing Instagram, Facebook, YouTube, TikTok, and Snapchat to hook children and teenagers, causing depression, anxiety, body dysmorphia, and compulsive use. Thousands of cases are now moving through federal and state courts. In March 2026, the first case to reach a jury ended in a $6 million verdict against Meta and Google, and a New Mexico jury the day before ordered Meta to pay $375 million in civil penalties. Both companies are appealing.
What the Lawsuits Actually Claim
The claims are not about what users posted. They are about how the platforms were built. Plaintiffs argue that features like algorithmic feeds, infinite scroll, autoplay, push notifications, likes, streaks, and appearance-altering filters were engineered to maximize engagement in ways that exploit the developing brains of young users.1UCLA Law Review. Addicted by Design: Reassessing Section 230 in the New Era of Social Media Addiction Litigation
Three legal theories carry most of the cases:
- Design defect — the platforms are unreasonably dangerous products because of how they are built.
- Negligence — the companies failed to implement adequate age verification and parental controls.
- Failure to warn — the companies knew about the harms, often documented in their own internal research, and did not disclose them.
Internal company documents surfaced in the California trial gave the theory teeth. A YouTube strategy memo stated, “If we want to win big with teens, we must bring them in as tweens,” and another declared, “The goal is not viewership, it’s viewer addiction.” An internal Instagram message read, “We’re basically pushers… We’re causing reward deficit disorder, because people are binging on Instagram so much they can’t feel the reward.”2Courthouse News Service.

The First Verdict: $6 Million Against Meta and Google
The bellwether case was tried in Los Angeles Superior Court before Judge Carolyn Kuhl as part of coordinated proceeding JCCP 5255. The plaintiff, a 20-year-old woman identified as K.G.M., was randomly selected from among roughly 1,600 plaintiffs in the California coordinated docket.3PBS NewsHour.

K.G.M. testified that she experienced depression, anxiety, and body dysmorphia, and that she compulsively checked Instagram for likes. She attributed her body image struggles largely to augmented reality filters. Mark Zuckerberg and Instagram head Adam Mosseri both testified for the defense. Mosseri drew a distinction between clinical addiction and “problematic use,” and a YouTube vice president stated that the platform was “not designed to maximize time.”5NBC News.

On March 25, 2026, the jury found both companies negligent, concluding they knew their products could be dangerous to minors and failed to provide adequate warnings. The jury awarded $3 million in compensatory damages and, after finding the companies acted with “malice, oppression, or fraud,” added $3 million in punitive damages. Meta was assigned 70 percent of the liability ($4.2 million), Google 30 percent ($1.8 million).6ABC7 News.

Both companies moved to overturn the verdict. On June 9, 2026, Judge Kuhl denied the motions and upheld the full award. She wrote that there was “substantial evidence that Plaintiff was harmed by the design features of Instagram, regardless of any of the content found on that platform.”8CNBC.

The Section 230 Question
Section 230 of the Communications Decency Act shields internet platforms from liability for what their users post. For years it defeated cases like these at the pleading stage. What changed is how courts now treat the line between content and conduct.
Judge Yvonne Gonzalez Rogers, who runs the federal multidistrict litigation, drew that line in November 2023: claims treating platforms as publishers of user content were dismissed, but design-defect and failure-to-warn claims were allowed to proceed.1UCLA Law Review. Addicted by Design: Reassessing Section 230 in the New Era of Social Media Addiction Litigation Judge Kuhl adopted the same approach in California, barring claims that would hold companies liable for third-party content or online bullying but allowing claims targeting algorithms, notifications, infinite scroll, autoplay, likes, and filters.9Courthouse News Service.

In April 2026, the Massachusetts Supreme Judicial Court ruled unanimously in Commonwealth v. Meta Platforms, Inc., 497 Mass. 384, that state claims against Meta could go forward. Justice Dalila Wendlandt wrote that the claims “do not seek to impose liability on Meta for information provided by third parties” but instead “allege harm stemming from Meta’s own conduct.” The court declined Meta’s “invitation to read immunity so broadly.”10Courthouse News Service.

The Federal MDL and School District Cases
In October 2022, the Judicial Panel on Multidistrict Litigation consolidated federal social media addiction cases into In re: Social Media Adolescent Addiction/Personal Injury Products Liability Litigation, MDL No. 3047, in the Northern District of California. As of early 2026, at least 2,407 claims were pending, including cases filed by roughly 1,200 school districts alongside individual family claims.12U.S. District Court, Northern District of California. In Re: Social Media Adolescent Addiction/Personal Injury Products Liability Litigation13NPR. Meta, YouTube Social Media Trial Verdict
In November 2025, Judge Gonzalez Rogers denied motions by Meta, YouTube, Snap, and TikTok to dismiss the addictive-design claims. A year earlier, she had dismissed claims seeking personal liability against Mark Zuckerberg while letting the cases against Meta continue.14Tech Policy Press. Social Media Adolescent Addiction/Personal Injury Products Liability Litigation, MDL No. 3047
The first school district case to resolve was Breathitt County, Kentucky, the bellwether within the MDL. In late May 2026, weeks before trial, Meta settled for $9 million, TikTok and Snap for $8 million each, and YouTube for roughly $2 million — about $27 million total. The district had originally sought more than $60 million to fund mental health programs.15The New York Times. Meta Settlement in Social Media Addiction Lawsuit16TorHoerman Law.

State Attorneys General and the New Mexico Verdict
A separate government track is running alongside the private cases. In October 2023, a bipartisan coalition of 42 attorneys general sued Meta over Instagram and Facebook. Thirty-three states filed jointly in the Northern District of California, led by New York Attorney General Letitia James. Nine additional states and the District of Columbia filed in their own courts, and Florida filed independently in federal court.17Office of the New York State Attorney General.

The coalition alleges that Meta used algorithms, likes, infinite scroll, and alerts designed to addict young users; collected data on children under 13 without parental consent, in violation of the federal Children’s Online Privacy Protection Act; and concealed internal research documenting harms.18Office of the New Jersey Attorney General. AG Platkin, 41 Other Attorneys General Sue Meta for Harms to Youth From Instagram, Facebook More than 40 states have now filed some version of a suit.
One day before the California verdict, a jury in New Mexico’s First Judicial District Court in Santa Fe ordered Meta to pay $375 million in civil penalties after finding that the company violated the state’s Unfair Practices Act. The penalty was calculated at $5,000 per violation, across two counts, for 37,500 affected users.19Source NM.

Who Is Suing and Who Represents Them
The plaintiffs fall into four groups: individual users and families claiming personal injury; school districts seeking to recover mental health program costs; state attorneys general bringing consumer protection and public nuisance claims; and, in some filings, states pursuing damages tied to youth harms.
The Social Media Victims Law Center, founded in 2021 by Matthew Bergman after Facebook whistleblower Frances Haugen’s disclosures, represents more than 4,000 clients and bills itself as the first firm focused exclusively on suing social media companies on behalf of children. More than 1,300 of its clients are in the federal MDL, and roughly 1,500 of its cases have survived Section 230 challenges. Firm partner Laura Marquez-Garrett was counsel of record for K.G.M.21TIME.

What’s Next
Meta and Google are appealing the $6 million California verdict. Meta is appealing the $375 million New Mexico penalty. Thousands of federal and state cases remain pending, with more trials expected over the next two years. The Breathitt County settlement gives both sides a benchmark for the remaining school district claims. Courts have, so far, refused to expand Section 230 to cover design decisions, and the Supreme Court has declined to intervene.
Congress has not passed major federal legislation on the issue. The Kids Online Safety Act, which would impose a duty of care on platforms toward young users, passed the Senate in 2024 but stalled in the House. Senators Marsha Blackburn and Richard Blumenthal reintroduced it in May 2025 with bipartisan support; it remains pending. The updated version clarifies that the FTC and state attorneys general could not use it to bring lawsuits over content or speech, addressing earlier First Amendment concerns.22TIME. Kids Online Safety Act Status: What to Know California and New York have enacted state laws requiring mental health warning labels on platforms used by minors, with California’s taking effect in January 2027.
If you believe a child in your family was harmed by a social media platform and you are considering a claim, the practical next step is a consultation with a firm handling these cases. Time limits vary by state, and the coordinated proceedings have their own intake processes.
