Boston has joined a growing legal battle against major social media companies. The city filed a lawsuit this week against Meta, TikTok, Snapchat, and YouTube, claiming their platforms harm children’s mental health. This lawsuit will be combined with over 1,500 similar cases from school districts nationwide, becoming part of a multidistrict litigation case in Northern California. This move adds momentum to an ongoing legal effort that is looking toward upcoming high-profile trials.
The lawsuits claim social media companies designed their platforms to keep young users online longer. Features like infinite scroll, autoplay videos, and push notifications encourage excessive usage. Plaintiffs argue these features exploit children’s developmental vulnerabilities, harming sleep, social skills, academic performance, and overall mental well-being. The companies deny these accusations, stating they have invested in parental controls and safety tools.
The action by Boston follows a rural Kentucky school district settlement with Meta and YouTube for around $27 million. This case was the first federal bellwether in the multidistrict litigation. Now, focus shifts to test cases in Tucson, Arizona, and Charleston, South Carolina. These cases are scheduled to begin in February 2027, according to Previn Warren, co-lead counsel for the plaintiffs.
U.S. District Judge Yvonne Gonzalez Rogers selected six school districts as bellwether cases to test the legal arguments. Aside from Tucson and Charleston, districts in Maryland, Georgia, and New Jersey were also chosen. A separate trial is set for August against Meta, initiated by state attorneys general. They claim Facebook and Instagram promote excessive use by children, misleading the public about platform risks. This trial is part of the broader litigation and will take place in California.
Several states have pursued their own legal actions, separate from the multidistrict litigation. Nine states have brought cases in their own courts, advancing claims that companies, including Meta and YouTube, designed features to retain young users. Although many government and school district cases are unresolved, some plaintiffs have achieved early successes. In March 2026, a Los Angeles jury held Meta and YouTube liable in a youth addiction case, awarding $6 million to a young woman harmed by social media addiction. Meta plans to appeal.
Plaintiffs view these outcomes as evidence that their legal campaign is gaining strength, even as companies continue to contest the allegations. This multidistrict litigation was originally filed in 2022, with more plaintiffs joining over time, as stated by Warren to Newsweek.
