Meta Platforms Inc. (META) CEO Mark Zuckerberg testified on February 18, 2026, in Los Angeles Superior Court, disputing claims that Instagram was designed to addict minors. Jurors are reviewing internal documents and evidence that could influence a wave of coordinated litigation involving roughly 1,500 similar lawsuits nationwide.
Zuckerberg Challenges Addiction Claims
Zuckerberg told jurors that Meta views high user engagement as a sign of product value, not evidence of engineered addiction. The defense argued that "social media addiction" lacks clinical recognition and does not prove causation. Meta highlighted safety features such as parental-overview tools and restricted teen accounts as efforts to protect young users. The defense also attributed the plaintiff’s mental health struggles to difficult family circumstances rather than platform design.
During testimony, the judge issued a stern warning threatening contempt charges over the use of AI-generated media in the courtroom.
Trial Evidence and Legal Stakes
The case, docketed as Judicial Council Coordination Proceeding JCCP 5255 in Los Angeles Superior Court, names Meta and Google as defendants. Google has argued that YouTube should be classified as an entertainment service similar to streaming platforms, not a social-media product.
Plaintiffs allege that companies intentionally designed addictive features—including infinite scroll, like buttons, beauty filters, and push notifications—to maximize engagement. Their claims proceed under negligence and public-nuisance theories, framing harms as products of design rather than third-party content. Plaintiffs have compared their legal strategy to Big Tobacco litigation.
The bellwether plaintiff, identified as K.G.M., age 20, began using YouTube at age six and Instagram at age nine. Court filings say she sometimes spent up to 16 hours daily on the platforms and attributes anxiety, body dysmorphia, depression, and suicidal ideation to that use.
Internal Instagram emails entered into evidence include one stating, "IG [Instagram] is a drug. We are pushing users." The filings also reveal an internal debate over whether to reverse a ban on facial filters that mimic plastic surgery results. Some staff urged maintaining the ban while research on effects for teen girls continued.
About 1,500 similar lawsuits are pending nationwide, with multiple state attorneys general filing separate actions. School-district lawsuits consolidated in the Northern District of California are scheduled for argument beginning summer 2026.
The trial raises a novel question of Section 230 liability, a 1996 law shielding platforms from liability for third-party content. Defendants emphasize this content-based protection, while plaintiffs argue that platform features and algorithms differ from content and are not covered. A plaintiff verdict could increase settlement pressure and prompt operational changes. A defense verdict would likely hinder similar claims and alter plaintiffs’ litigation strategies.
