Meta Faces $1.4 Trillion Threat, Stock Drops as Landmark Youth-Safety Trial Begins

The Meta trial over child safety opened in Oakland federal court on Tuesday, and Meta Platforms stock fell 4.45% to $543.67.

Four US states accuse the company of hooking teenagers through addictive design. Meta’s own filing put the theoretical penalty as high as $1.4 trillion.

Where the Meta Trial’s $1.4 Trillion Number Came From

California, Colorado, Kentucky and New Jersey brought the case. The states never demanded a fixed $1.4 trillion, however. Meta produced that number itself in July, when it responded to the states’ brief on how penalties should be calculated.

Meta called those calculations outlandish and without precedent in consumer protection enforcement. The states, meanwhile, told the judge that roughly $200 billion is the more likely figure.

California Attorney General Rob Bonta has framed the case around restitution rather than damages. Judge Yvonne Gonzalez Rogers is presiding, and the trial should run about six weeks.

Tuesday’s drop extends a longer slide. META has now lost 6.38% over five days and 16.06% across the past month. The stock also sits 29.86% lower than a year ago.

Why the Remedies Threaten the Stock More Than the Fine

The states argue that Meta built infinite scroll, autoplay, and beauty filters to trigger compulsive use. They also claim the company knew about the mental health damage and played it down in public.

“Meta said it prioritized safety over profits, but…profits won.”

Therefore, the Meta trial’s injunction risk matters more than the headline number. The states want Meta to delete data collected from users under 13, scrap AI models trained on that data, and strip out the addictive features. Any such order would reach the recommendation systems behind Meta’s advertising engine.

That revenue funds Meta’s entire AI push, from record AI infrastructure spending to a compute deal with Anthropic and the open weight superintelligence push. Its second quarter earnings report already showed margins shrinking.

Meta rejects the allegations and points to stronger teen privacy defaults plus Instagram’s one-hour usage reminder. Its lawyers also lean on the First Amendment and Section 230 of the Communications Decency Act, the law shielding platforms from liability over user posts.

Jim Cramer blames the venue of the Meta trial, not the merits, for Tuesday’s selloff.

Meta trial in the worst possible district for corporate defendants, hence why the stock is being hammered. But the case, while strong enough, might not survive a supreme court review. Contrary view but i didn't go to law school for nothing

Precedent gives both sides something. A New Mexico jury found Meta liable in March and ordered $375 million, far below the $1.9 billion sought there. Penalties in that case ran at $5,000 per violation, the same math that scales into the trillions here.

Mark Zuckerberg is expected to testify, alongside whistleblower and former Meta engineer Arturo Bejar. In the meantime, investors will watch whether the Meta trial produces documents as damaging as the opening statement.
