Meta faces landmark trial over social media addiction claims as states seek up to $1.4 trillion in penalties

Four US states have hauled Meta into federal court in Oakland, California, alleging the company deliberately engineered Instagram and Facebook with addictive features designed to hook children and teenagers. The trial, which began on August 18, represents the most significant legal challenge Meta has faced over claims that its platforms harm minors.

California, Colorado, Kentucky, and New Jersey are collectively seeking penalties estimated between $200 billion and $1.4 trillion.

What the states are arguing

The core allegation is straightforward: Meta knew its platforms were causing mental health damage to young users and chose profits over protection. The states claim the company violated the Children’s Online Privacy Protection Act, known as COPPA, by collecting data on users under the age of 13.

The plaintiffs also argue Meta actively concealed known mental health risks associated with its platforms.

This bellwether trial stems from a broader multi-district lawsuit initiated in 2023, originally involving 29 states. The four states selected for this initial trial are essentially test cases. Their outcome will likely shape how hundreds of remaining claims proceed.

The trial is expected to run four to six weeks, and Mark Zuckerberg himself is scheduled to testify.

A pattern of courtroom losses

In March 2026, a jury found both Meta and YouTube liable in a similar case, resulting in a $6 million damages award to a single plaintiff.

A separate ruling in New Mexico went considerably further, ordering Meta to pay $567 million for mental health harms suffered by children on its platforms. Meta has appealed at least one earlier verdict related to social media addiction claims.

Meta’s defense centers on the argument that it has implemented multiple safety features across its platforms. The company denies the core allegations.

The stakes beyond the courtroom

Even if the final penalty lands well below the $1.4 trillion ceiling, the operational reforms the states are seeking could prove more consequential than any dollar figure. Court-ordered changes to how Facebook and Instagram function would represent a fundamental shift: a tech company’s product design being dictated not by its engineering teams or growth metrics but by judicial mandate.

The timing is notable as well. This trial arrives amid a broader global regulatory push to constrain how tech platforms interact with minors. Australia has moved to ban social media for children under 16. The European Union’s Digital Services Act imposes stringent obligations on platforms regarding minor safety.
