Instagram and YouTube Face Addiction Lawsuit
A landmark civil trial in Los Angeles is putting Instagram and YouTube on trial over accusations that their platforms are “designed to be addictive” and harmful to children’s mental health — a case that could reshape how social media companies are legally held accountable for the effects of their products on young users. ## The lawsuit, filed in 2023 by a California woman identified only as K.G.M., is the first of many similar claims pending nationwide. The plaintiff alleges that prolonged use of social media, beginning in early childhood, contributed to serious mental health issues including depression and suicidal thoughts. Opening arguments in the case began on February 9, 2026, before a jury at the Los Angeles County Superior Court. The two remaining defendants are Meta Platforms (parent company of Instagram) and Google’s YouTube — while TikTok and Snap have settled earlier lawsuits related to this case.
Plaintiff’s lawyers argue that these technology giants intentionally engineered features that exploit psychological vulnerabilities in children to extend engagement and increase profits. They contend that elements such as infinite scrolling, algorithm-driven recommendations, autoplay videos, and social feedback mechanisms were designed to maximize user attention and can function similarly to addictive substances, leading to compulsive use and long-term mental health harm. The attorney for the plaintiffs, Mark Lanier, told jurors that the case is “as easy as ABC” — standing for Addicting the Brains of Children — and drew comparisons to the historic lawsuits against the tobacco industry.
Opening statements painted the companies as entities aware of the risks yet unwilling to act. Lawyers for the plaintiffs presented internal documents and communications suggesting that company employees had at times described platform use in addictive terms. They also pointed to studies indicating that adolescents and children are particularly vulnerable to algorithmic design that prioritizes engagement over safety. At one point, a witness told the jury that children as young as six were using YouTube and later joined Instagram as tweens, exposing them to endless streams of content.
The defendants strongly reject the core accusations. Instagram head Adam Mosseri testified that social media platforms are not clinically addictive, and stressed a distinction between clinical addiction — a recognized medical condition — and what he described as “problematic use,” where someone spends more time on a platform than they feel is healthy. Mosseri said that Instagram tries to balance safety and freedom, and argued that the term “addiction” is misused outside clinical definitions. He pointed out that tools and features that may encourage engagement are not the same as deliberate attempts to harm users.
YouTube’s legal team went further, asserting in opening arguments that YouTube is not even a social media platform in the traditional sense, but rather an entertainment service where users choose content they want to watch. They argued that features like infinite scroll and recommendations are meant to enhance user choice and are not designed to rewire brains. YouTube’s defense also highlighted user data suggesting that average watch times do not support claims of addictive behavior on their platform, and emphasized tools users have to manage their own viewing habits.
The trial is being treated as a bellwether case — essentially a test case for how similar lawsuits might fare in courts across the United States. There are hundreds of related lawsuits alleging that social media companies have minimized known harms, failed to protect young users, and designed their products for profit at the expense of well-being. If the plaintiff prevails, it could lead to significant financial liabilities, changes to platform design practices, and potentially new regulatory expectations for social media giants.
Emotional testimony has already emerged during proceedings, with discussions touching on the experiences of young individuals whose mental health struggles they attribute, at least in part, to heavy social media use. At times, observers in the courtroom reacted visibly during testimony about body image issues and compulsive usage patterns linked to platform features. The judge has warned the public not to show support or opposition during proceedings, underscoring the high-profile nature of the case.
The outcome of this trial may also influence ongoing and future legislative efforts both in the United States and abroad to address children’s safety online, content moderation standards, and the responsibility of technology companies to mitigate harm.
