The wave of litigation currently sweeping through U.S. courts brings claims against the world’s most powerful companies. It targets the "Big Four" technology companies, which dominate how American teenagers spend their time online.
Compulsive use, excessive scrolling (sometimes called doomscrolling), anxiety and depression, and failure to protect minors are among the allegations and harms cited in these lawsuits. Plaintiffs alleged that features such as infinite scroll, autoplay, and recommended content driven by algorithms were partly responsible for the negative impacts on mental and physical health.
They also argue that platforms failed to protect minors by designing products that exploit psychological vulnerabilities while providing insufficient warnings, and the courts are examining these issues in current proceedings.
Influent tech firms are not being sued for the content on their apps, but for the deliberate design of the apps themselves, which attorneys argue were engineered to function like "digital casinos," exploiting the human brain’s limits of self-control.
While many platforms are being monitored, the primary defendants named in the federal Multidistrict Litigation (MDL 3047) and state court actions are:
As the largest defendant, Meta faces thousands of claims. The plaintiffs introduced internal documents at the February 2026 trials, showing discussions of features such as "infinite scroll" and beauty filters, which affect children’s ability to self-regulate and lead to body dysmorphia and eating disorders, all while allegedly ignoring internal research (see the “Facebook Papers”) that warned of these dangers. Meta executives, including CEO Mark Zuckerberg, are expected to testify in a California courtroom on 18 February 2026.
Google is being sued for YouTube’s “Autoplay” and recommendation engines. The lawsuits claim these features push children down ‘rabbit holes’ of content that can make it difficult for minors to ignore and direct them toward harmful material they didn’t ask for.
Unlike other platforms, YouTube is more often used by very young children, making the allegation regarding “targeting minors” particularly severe.
Out of all these platforms, TikTok’s short video design and “For You” algorithm is arguably the most finely tuned dopamine delivery system. Plaintiffs argue that the rapid-fire nature of short films can put children in a sort of trance, making it nearly impossible for them to disconnect.
TikTok reached a settlement with the plaintiff during the recent K.G.M. v. Meta et al. proceedings, which served as a bellwether (test) trial to test key issues for cases of this kind.
Similar to TikTok, Snap Inc. has moved toward settling the “bellwether” cases in early 2026. The lawsuits against Snap are likely to focus on features such as “Snapstreaks,” which encourage users to exchange messages daily or risk losing the streak.
The lawsuits against these defendants are based on claims of defective design and failure to warn, using legal theories similar to product liability.
Note: This litigation is fast-moving. While Snap and TikTok have settled specific individual cases as of early 2026, the broader federal litigation against all four companies continues. If you believe you have a claim, time is of the essence.
