Meta Faces Landmark 29-State Trial Over Instagram and Facebook Youth Safety Claims

August 18, 2026

Meta Platforms is facing one of its most consequential legal challenges yet as a coalition of 29 U.S. states takes the company to federal court over allegations that Facebook and Instagram were designed in ways that could harm children and teenagers.

The trial began Tuesday in Oakland, California, with attorneys general from Colorado, California, New Jersey and Kentucky leading the case on behalf of the bipartisan group. The proceedings could eventually force significant changes to the way Meta operates its two major social-media platforms and could expose the company to enormous financial penalties.

What the states are alleging

At the center of the lawsuit is the claim that Meta deliberately built features that encouraged young users to spend extended periods on its services. The states argue that the company knew about potential risks to children and teenagers while continuing to operate products in ways that could contribute to those problems.

The legal action also includes allegations involving children's personal information. The 29 states accuse Meta of collecting and using data from minors in violation of federal law.

The case is therefore broader than a dispute about social-media design. It combines questions about youth safety, consumer disclosures and the handling of children's data, making it a closely watched test of how technology companies may be held accountable for the way their products affect younger users.

A trial with an unusual jury role

The proceedings have an unusual structure. An eight-member jury is hearing the case, but it is serving in an advisory role rather than having the final say.

U.S. District Judge Yvonne Gonzalez Rogers will ultimately decide the case. The advisory jury is expected to provide its assessment as the judge considers the evidence and arguments presented during the multiweek proceedings.

Meta CEO Mark Zuckerberg and Instagram chief Adam Mosseri are expected to testify, putting senior company leadership directly in the spotlight.

The states are expected to rely on internal company documents, research and testimony from former Meta employees and outside experts as they seek to establish their claims.

Meta rejects the allegations

Meta has strongly disputed the states' accusations. The company says it has invested substantially in protections intended to make its services safer for teenagers and rejects the suggestion that it misled consumers about the risks associated with its platforms.

The company has also argued that the states have not demonstrated that residents were actually deceived or harmed in the manner alleged in the lawsuit.

Meta has criticized the potential scale of the financial claims, describing the states' demands as excessive and arguing that some of the issues raised in the lawsuit, including age verification, are challenges affecting the wider social-media industry rather than problems unique to Meta.

Potential financial and business consequences

The financial stakes are unusually high.

Meta has said potential penalties could reach as much as $1.4 trillion, an amount approaching the company's reported market value. The states have not formally settled on a final penalty figure, although attorneys general indicated during a recent hearing that the eventual amount could be substantially lower, potentially around $200 billion.

Beyond monetary damages, the states are seeking changes to Meta's platforms that could affect millions of users.

Among the proposed measures are stronger age restrictions and the removal of infinite scrolling. The states also want other nationwide modifications to Instagram and Facebook if the court rules in their favor.

Such measures could have implications for how Meta designs engagement features and verifies the ages of users. They could also influence how other technology companies approach similar features on their own platforms.

The case began with a wider investigation

The lawsuit was filed in 2023 following a multistate investigation into the effects of Instagram and Facebook on young users.

That investigation gained momentum after former Meta employee Frances Haugen testified before a U.S. Senate committee in 2021. Haugen alleged that the company had information about potential risks to young users and understood ways its products could be made safer.

The states subsequently pursued their own investigation and litigation, eventually bringing together a large coalition of attorneys general.

The case now forms part of a much larger legal battle over the responsibilities of social-media companies. Meta, along with companies behind TikTok, YouTube and Snapchat, is facing thousands of lawsuits from governments, schools, communities and individuals concerning alleged harms to young users.

A decision that could influence the wider industry

The outcome could extend well beyond Meta.

If the states succeed in obtaining major financial penalties or court-ordered changes to Instagram and Facebook, other social-media companies could face greater pressure to alter youth-focused features, strengthen age controls and reconsider how children's information is collected and used.

A victory for Meta, meanwhile, could make it harder for governments pursuing similar cases to establish that platform design itself creates legal liability.

With the trial placing the business practices of one of the world's largest technology companies under intense scrutiny, the eventual ruling is likely to become an important reference point in the continuing debate over how social-media platforms should protect young users while operating commercially at enormous scale.
