The world’s biggest social media companies have reached a dozen confidential settlements in recent months with teen plaintiffs over claims the platforms damaged their mental health. The payouts were secret, but Bloomberg Businessweek has learned that most ranged from $2 million to $2.5 million.

And in just the past two weeks, Meta Platforms Inc. agreed to pay two of these teens a combined $7 million, according to people familiar with the payments who didn’t want to be identified discussing confidential information.

These settlement numbers, reported for the first time, provide a rare glimpse into what the companies are willing to pay to avoid high-profile trials with teen users — and the looming financial risk such cases present. Roughly 9,800 personal injury cases are pending in state and federal court against Meta, Google’s YouTube, Snap Inc. and TikTok Inc.

A single $2 million settlement, reached with one teen, is a fraction of the $18 billion that Meta agreed in August to pay a group of states that had sued the platform for harming children by designing addictive features, such as nonstop scroll or the “like” button. It is also a fraction of the billions of dollars the companies might end up paying to the 2,000 school districts that have filed similar suits and are awaiting their day in court. But what makes these multimillion-dollar settlements with individual teens so noteworthy is the volume of cases.

Combined, these personal injury lawsuits, which are being filed around the country, could potentially expose the companies to yet another multibillion-dollar liability.

Mark Lanier, lead trial attorney for two of the four plaintiffs, said in an interview that he couldn’t confirm or deny the individual settlement amounts. But, he said, the companies “offered so much money that my clients could not refuse. These are not insignificant numbers. I believe they are the first dominoes to fall in what will be a succession of dominoes to come.”
