A landmark trial against three of the largest social media companies in the world began on January 27, 2026, in Los Angeles County Superior Court, marking the first time that claims of social media addiction among young users have gone before a jury in the United States. Meta, the parent company of Instagram, ByteDance, which operates TikTok, and Google, the owner of YouTube, are all named as defendants in a case that could reshape how the technology industry approaches child safety and platform design.
The plaintiff, identified only as K.G.M. to protect privacy, is now 19 years old and alleges that prolonged exposure to social media platforms beginning at age 10 led to severe mental health consequences including depression, anxiety, and body dysmorphia. Attorneys representing K.G.M. argue that the companies were fully aware their products were designed in ways that created compulsive usage patterns among minors, yet prioritized engagement metrics and advertising revenue over the wellbeing of their youngest users.
Snap Inc., the parent company of Snapchat, was originally named as a co-defendant but reached a settlement last week for an undisclosed sum, leaving Meta, ByteDance, and Google to face the jury alone. The settlement by Snap is widely viewed as a signal that at least one major platform chose to avoid the reputational and financial risks of a public trial. Judge Carolyn Kuhl is overseeing the proceedings, which are expected to last several weeks and attract intense public scrutiny.
One of the most anticipated developments in the case is the expected testimony of Meta chief executive Mark Zuckerberg, who may be called to answer questions about internal company research that allegedly showed Instagram was harmful to teenage users, particularly young girls struggling with body image. His appearance on the witness stand would represent a rare moment of direct accountability for a technology executive in a courtroom setting focused on the mental health impact of social media.
The defense teams for all three companies have mounted a vigorous response, arguing that no clinical diagnosis of social media addiction currently exists within established psychiatric frameworks. They contend that their platforms have introduced numerous safety features in recent years, including parental controls, screen time limits, and age-verification tools, and that parents bear primary responsibility for monitoring their children's online activity. The companies also maintain that their platforms provide significant social and educational benefits to young users.
A key legal issue in the trial involves Section 230 of the Communications Decency Act, which traditionally shields technology companies from liability for user-generated content. Judge Kuhl has partially applied Section 230 protections, but has ruled that the jury will be allowed to evaluate whether specific platform design features, such as infinite scrolling, autoplay videos, and algorithmic recommendation systems, were intentionally engineered to maximize time spent on the apps regardless of harm to minors.
Legal analysts say the outcome of this trial could set a powerful precedent for thousands of similar lawsuits filed across the country by families alleging that social media platforms caused psychological harm to their children. A verdict against the companies could represent an existential threat to core elements of social media business models, potentially forcing sweeping changes to how platforms are designed and marketed to younger audiences. Regardless of the jury's decision, the trial has already elevated the national conversation about the responsibilities of technology companies toward their most vulnerable users.
