A 9th Circuit court in San Francisco ruled that social media addiction lawsuits against Meta can proceed. The path was set in March, when a California jury found that using both Meta and YouTube can cause significant health impacts through intentionally designed addictive systems. The court found both companies ignored risks in order to maximize business opportunities, and ordered each to pay $3 million in damages to a single plaintiff.
That finding established a new precedent — that social media addiction can cause significant harm and stress — which now opens Meta to a broad range of claims from others alleging pain and suffering caused by its apps.
Meta sought to dismiss the California ruling by arguing that social media addiction is not a psychological condition recognized in the Diagnostic and Statistical Manual of Mental Disorders, the reference guide courts lean on for rulings of this type. The latest decision means other cases move forward regardless: Meta has not produced arguments convincing enough to halt proceedings.
The company is simultaneously preparing for a federal trial on the merits of these claims, as reported by the LA Times. Alongside the DSM argument, Meta contends there is equal evidence that its products benefit older adolescents, and it is seeking Section 230 protections to shield itself from liability.
Reuters has reported that total potential payouts could exceed $1.4 trillion. Meta's market cap sits around $1.5 trillion, which frames the exposure. If precedent hardens and social media addiction is treated as real harm, this becomes an existential business problem rather than a legal cost line. Meta may also lean on the U.S. government for protection if things go badly, which could stretch the cases out for years.
First, this can become an inventory stability question. Depending on outcomes, restrictions on teen-facing delivery and recommendation systems would change how campaigns targeting that cohort are built.
Second, keep platform trust in the regular brand-safety review. On how trust already constrains Meta's AI ambitions, see Meta's AI Plans Run Into a Trust Problem, Not a Technical One; for the long-range plan itself, Zuckerberg's 6,500-Word AI Manifesto.
Third, no short-term action is required. Federal proceedings and settled precedent take time. Brands heavily weighted toward teen audiences should still keep an alternative channel scenario ready.
The 9th Circuit ruled that social media addiction lawsuits against Meta can proceed, meaning Meta failed to present arguments strong enough to stop the proceedings.
A jury found that using Meta and YouTube can have significant health impacts due to intentionally designed addictive systems, and ordered each company to pay $3 million in damages to one plaintiff.
Reuters reported that total payouts could exceed $1.4 trillion. Meta's market capitalization is roughly $1.5 trillion.
