Meta goes on trial over social media addiction and child privacy claims

A federal jury trial kicked off this week in Oakland, California, that could reshape how social media companies interact with their youngest users. Meta Platforms is facing allegations from four states that its platforms, Facebook and Instagram, were engineered to be addictive for children while the company quietly buried evidence of the mental health damage they caused.

The states of California, Colorado, Kentucky, and New Jersey are seeking up to $1.4 trillion in penalties. For context, Meta’s entire market capitalization sits at roughly $1.5 trillion.

What the states are arguing

The trial is expected to last four to six weeks. The states’ attorneys general say Meta knowingly built products that harmed kids. Their case focuses on specific design choices, things like infinite scroll and recommendation algorithms, that they argue were deliberately calibrated to maximize engagement and advertising revenue at the expense of user wellbeing.

A core legal thread involves the federal Children’s Online Privacy Protection Act, known as COPPA. The states allege Meta collected data on users under 13 without obtaining parental consent, a direct violation of the law. COPPA has been on the books since 1998, long before Instagram existed, and it sets a hard line: companies must get verifiable parental consent before harvesting personal data from young children.

Meta has dismissed these claims as unfounded and disproportionate, maintaining that it has robust protective measures in place for young users.

The trial will feature testimony from Meta CEO Mark Zuckerberg and Instagram head Adam Mosseri.

The legal track record so far

In March 2026, a jury in New Mexico found Meta liable for contributing to mental health harm in minors and ordered the company to pay $375 million. A separate California jury awarded $6 million in a case that involved both Meta and YouTube.

The current trial stems from a broader lawsuit initiated in 2023 that originally involved roughly 30 states accusing Meta of violating youth safety and privacy standards. The case was consolidated into a multidistrict litigation. The four states going to trial now represent the sharpest edge of that broader effort.

Former Facebook employee Frances Haugen’s 2021 disclosures, which included internal research showing Instagram’s negative effects on teen mental health, cracked open a conversation that hasn’t closed.

What this means for Meta and the broader tech landscape

The financial stakes here are genuinely existential, at least in theory. A $1.4 trillion penalty would be unprecedented in American legal history. The states aren’t just seeking money. They want product changes, which could mean restrictions on features like algorithmic recommendations, autoplay, and push notifications for minors.
