Zuckerberg Testifies in Landmark Social Media Addiction Trial
Meta CEO Mark Zuckerberg took the stand on Wednesday, February 18, 2026, in a Los Angeles courtroom to defend his company against allegations that its social media platforms are intentionally addictive and harmful to young users. The trial, which began in late January, centers on a lawsuit brought by KGM, a 20-year-ancient plaintiff who claims social media use from a young age led to addiction and mental health issues.
The Core of the Lawsuit
KGM alleges that Facebook, Instagram, and YouTube—through their recommendation algorithms and infinite scrolling features—are designed to be addictive. The outcome of this case could significantly impact the thousands of similar lawsuits filed against social media companies. TikTok and Snapchat previously settled similar claims before the trial commenced. CBS News reports that Meta strongly disputes these allegations, asserting its commitment to supporting young users and claiming KGM experienced mental health challenges prior to using social media.
Zuckerberg’s Testimony and Key Questions
Zuckerberg’s testimony marks the first time the Meta CEO has had to defend his company in front of a jury. The Independent details that attorneys questioned Zuckerberg about internal documents, including a “Zuckerberg comms plan” outlining strategies to avoid appearing “fake, robotic, corporate and cheesy.”
He was also pressed on his previous statement regarding platform design, to which he reiterated his belief that companies should focus on creating “useful” products that naturally attract users. Sky News reported on this exchange.
Age Verification and User Data
During questioning, Zuckerberg addressed concerns about the age of Instagram users. He stated that a “meaningful amount” of users lie about their age when signing up for the platform. CNBC reports that he acknowledged the company removes identified underage users and includes age-related terms in the sign-up process, but faced scrutiny over the expectation that a nine-year-old would read the fine print.
Comparisons to the Tobacco Industry
Experts have drawn parallels between this social media trial and the legal battles waged against the tobacco industry in the 1990s, suggesting a similar effort to hold companies accountable for the potential harms of their products and marketing practices. CBS News highlighted this comparison.
Looking Ahead
The outcome of this landmark case is expected to have far-reaching implications for the social media industry, potentially shaping future regulations and legal challenges. The trial continues, with further testimony and evidence expected to be presented in the coming weeks. AP News provides ongoing coverage of the proceedings.
