March 30, 2026 A US jury has ruled against Meta in a landmark social media addiction case, awarding $4.2 million in damages and finding the company deliberately designed addictive features that harmed a young user. The decision found that Meta deliberately designed addictive product features and also implicates YouTube, which was ordered to pay $1.8 million.
The verdict follows a Los Angeles jury finding that YouTube’s design contributed to youth harm, adding to mounting legal scrutiny of social media business models.
The ruling centres on how platforms are built. Plaintiffs argued that features such as infinite scroll and autoplay were intentionally designed to maximise engagement, contributing to compulsive use and mental health issues. Internal communications presented during the trial suggested employees were aware of these dynamics, with messages describing Instagram as “a drug” and its operators as “pushers.”
Meta’s defence focused on external factors, including family environment and offline experiences, arguing that mental health outcomes could not be attributed to a single app. The company has stated it will appeal, maintaining that “teen mental health is profoundly complex and cannot be linked to a single app.”
The jury was not persuaded. In a 10–2 decision, jurors concluded that product design choices played a direct role in harm, signalling a shift in how courts may interpret liability for digital platforms. As one juror said, the testimony from CEO Mark Zuckerberg “didn’t sit well.”
Public sentiment appears aligned with that shift. Surveys cited during the case show around 64 per cent of US adults believe social media has a negative impact on society, while nearly half of teens now say it harms people their age, a sharp increase in recent years.
The implications extend beyond individual cases. Legal arguments are now focusing on product architecture – how algorithms, feeds and engagement loops are designed – rather than solely on moderation or user behaviour. That reframing could challenge long-standing legal protections that platforms have relied on, particularly if courts continue to treat design decisions as intentional and actionable.
The verdict also coincides with increasing policy momentum globally, including age restrictions and platform accountability measures, suggesting legal and regulatory pressures are converging.
