Meta's $1.4T trial: 29 states say Instagram hooked kids

The number to sit with: $1.4 trillion. That's Meta's own estimate of its damages exposure in the trial that opened this week in Oakland federal court — and it's within shouting distance of the company's roughly $1.5 trillion market cap. A bipartisan coalition of 29 state AGs filed in 2023; California, Colorado, Kentucky and New Jersey are trying this first bellwether case, arguing Meta deliberately built Facebook and Instagram to hook minors and then misled parents about the risk. Jury selection is done, opening statements land August 18, and the thing is scheduled to run seven weeks, with Zuckerberg and Instagram chief Adam Mosseri expected on the stand.

The money is the headline, but the requested remedies are the part builders should read twice. The states want the court to mandate age gates, hard time limits for young users, the end of infinite scroll and constant notifications, an algorithm retuned for wellbeing over engagement — and deletion of AI models trained on children's data. That last one is a model-disgorgement demand, the AI equivalent of a product recall.

Meta's defense is definitional: "social media addiction" isn't a recognized psychiatric diagnosis, so consumers can't have been deceived about it. Over 6,000 related suits are stacked behind this one.

Why it matters: if a court can order trained models deleted because of how the training data was collected, every engagement-optimized AI system just acquired a new legal risk.
