Meta and CEO Mark Zuckerberg are in a bind.

The platform, worth about $1.43 trillion, is being sued by 29 states over alleged violations of the Children's Online Privacy Protection Act (COPPA). In the Big Tobacco-like case, the suit accuses Meta of knowingly selling an addictive product to teenagers as young as 13.

Meta's stock fell about 4.5% on Tuesday, continuing a long slide from its August 2025 high.

The suit was first filed in 2023 by a group of 29 states, ranging from deep red to bright blue, like California, New York, Kentucky, and Louisiana, along with others.

A core group of four states — California, Colorado, Kentucky, and New Jersey — are now leading the charge in Oakland, for the six-to-eight-week trial set to kick off on Wednesday. Zuckerberg, Instagram head Adam Mosseri, and Sheryl Sandberg, the former COO, are all scheduled to appear.

The core complaint is that Meta purposefully designed its revenue model around habit-forming "features" like infinite scroll, push notifications, and the social gamification of one's personal and social life in order to drive engagement and ad impressions. Which ultimately equals revenue.

It's clearly been working. Advertising makes up about 98% of Meta's total revenue based on their most recent earnings report.

The company's execs, the lawsuit alleges, knew how addictive their products were and did it anyway. The suit alleges Meta employees concealed internal research about the dangers of its products.

Between social comparison, harmful beauty filters, and Mosseri scrapping an AI tool meant to shield kids from risky content, it's no wonder a study called "Project Mercury" found that people who quit Facebook and Instagram saw their depression, anxiety, and loneliness drop. Instead of acting on it, they buried it, the suit alleges.

A spokesperson for Meta didn't immediately respond to a request for comment.

If this case goes south for Meta, the company has a lot to lose, and not just money. Let's start with the fine.

The 29 states are seeking roughly $200 billion in damages, a figure their lawyers put on the record during a pre-trial hearing. But state consumer protection laws let regulators calculate fines per individual violation, and if the court allows that math, the ceiling increases to a whopping $1.4 trillion.

That's roughly Meta's market cap, which makes this less a slap on the wrist and more like an extinction-level event.

The attorneys general are stacking at least three sets of statutes at once — false advertising, unfair competition and data privacy — on top of a COPPA claim, which carries built-in penalty multipliers whenever the user in question is under thirteen.

Every additional theory of liability is another lever on the same number. Judges have historically avoided doing this in the past because it could destroy the company, but given that Chief U.S. District Judge Yvonne Gonzalez Rogers, who is presiding over the case, is known to have zero tolerance for big tech companies breaking rules, hiding evidence, or misleading consumers, anything could be possible.

The timing of all of this couldn't be coming at a worse time for Meta. The stock hasn't caught a bid since August 2025, down from its all-time high of almost $800 to $547, about a 30% drop.

Social media writ large has been in steady decline according to a 2022 report from the Financial Times, citing, "adults 16 and over spent an average of two hours and 20 minutes per day on social platforms by the end of 2024, down almost 10% since 2022."

This case is structural, meaning if Meta loses, they will be forced to forever change how they operate.

The ruling could force the end of uninterrupted feeds and content autoplay functions, restrict visible "like" counts and social validation metrics for younger users, block push notifications, and more.

All this would be a death blow for their algorithms, which have driven Meta from a Harvard dorm room to one of the largest companies in the world in two decades.
