Meta has settled with both teenage plaintiffs in the fourth Los Angeles social media addiction bellwether trial, leaving Snap as the only defendant. NBC News reports Meta settled with S.J. on 29 October and K.D.B. on 30 October, with terms kept confidential. Opening statements against Snap are set for 4 November.
What happened
A California state judge consolidated the claims of two young women, known as S.J. and K.D.B., into one trial against Meta, Snap, TikTok and YouTube. TikTok and YouTube settled in the weeks before trial; Meta settled with both plaintiffs during jury selection. Snap now faces the jury alone.
The plaintiffs allege the apps were designed to be addictive and harmed their mental health after they started using them as young teens. A Meta spokesperson told AFP that trials, dismissals and settlements are all common in the bellwether process. Meta has repeatedly denied that its apps are purposefully harmful or addictive.
The bigger legal picture
This is one of a consolidated group of cases that NBC News says includes more than 1,600 plaintiffs, among them over 350 families and over 250 school districts. In March 2026 a Los Angeles jury found Meta and YouTube negligent in an earlier bellwether. In August, Meta agreed a settlement of about $18 billion with state attorneys general that included changes to how Instagram and Facebook work for teens, such as time limits and no notifications during school hours.
AFP notes that settling before trial keeps executives off the witness stand; Mark Zuckerberg and Adam Mosseri had been expected to be key witnesses.

Why media buyers should care
None of this changes Ads Manager today. But the steady run of verdicts and settlements keeps teen safety at the centre of Meta's product and policy decisions, and the August settlement already reshaped teen experiences on Instagram and Facebook. Further limits on how much time, reach or engagement younger users give the platform would also shrink the inventory advertisers can buy against them.
If your offers skew young, assume teen inventory will keep shrinking and get more expensive to reach compliantly.
What to do
Audit campaigns for any reliance on 13–17 audiences, check age gating on landing pages, and make sure creatives and offers are clearly appropriate for every age you allow. Brands near the youth market should keep an eye on the Snap trial, which opens 4 November, for what it signals about platform design claims.
