Social Media Adolescent Addiction Litigation: MDL 3047 Status

The social media adolescent addiction litigation is the consolidated federal proceeding for claims that the design of social media platforms led to compulsive use and mental health harm in adolescents. It is MDL No. 3047 in the Northern District of California, before Chief Judge Yvonne Gonzalez Rogers. The Judicial Panel on Multidistrict Litigation counted 3,824 actions pending as of October 1, 2026, out of 4,009 filed. The court has set bellwether trials for February 3, 2027, with a pretrial conference on November 13, 2026. No document reviewed for this article contains a judicial finding that a platform causes addiction or any other injury.

What the litigation is

The panel created MDL 3047 by transfer order dated October 6, 2022. The order states that the litigation then consisted of “28 actions pending in 17 districts” and that the panel had been notified of “56 related actions in 24 districts” (transfer order). It transferred the actions to the Northern District of California and assigned them to Judge Gonzalez Rogers for coordinated or consolidated pretrial proceedings.

The order described the common question before the panel:

These actions present common factual questions arising from allegations that defendants’ social media platforms are defective because they are designed to maximize user screen time, which can encourage addictive behavior in adolescents. Plaintiffs allege defendants were aware, but failed to warn the public, that their platforms were harmful to minors.

That passage reports allegations. It is not a finding that any platform is defective or that screen time causes harm.

An MDL is not a class action. Each plaintiff keeps a separate case, and the panel consolidates pretrial proceedings before one judge. The difference is explained in MDL versus class action.

The defendants named in the appellate caption include Meta Platforms, Instagram, TikTok and ByteDance, Google and YouTube, and Snap. Case Management Order No. 37, dated September 28, 2026, stays “all claims and proceedings against any non-primary defendants, including X Corp., Roblox, and Discord” (case management order).

How the court organized the claims

The Ninth Circuit’s August 10, 2026 opinion describes five tracks in the district court:

1. priority personal injury claims brought by individual plaintiffs;
2. claims brought by state attorneys general, plus three related non-priority individual claims;
3. the remaining non-priority individual claims;
4. claims brought by school districts and local governments;
5. claims against Meta chief executive Mark Zuckerberg in his individual capacity.

The opinion also records the dismissal rulings. On the first track, the district court granted Meta’s motion to dismiss in part and denied it in part, holding that section 230 of the Communications Decency Act bars some claims “only to the extent that they concern allegedly defective platform features targeting Meta’s role as a publisher of third-party content.” On the fourth track and most of the second, the court “generally denied” the motions and allowed the claims to proceed, while finding that section 230 provides “a fairly significant limitation” on the claims at issue (Ninth Circuit opinion).

What the Ninth Circuit decided

Meta and TikTok appealed the refusals to dismiss on section 230 grounds. On August 10, 2026, a Ninth Circuit panel dismissed the appeals for lack of appellate jurisdiction. The panel held that section 230 “merely provides a defense to liability, not immunity from suit,” so an order denying the defense can be reviewed after a final judgment. It also found that the district court “did not conclusively determine the disputed question because the district court indicated its willingness to revisit the issue of section 230 immunity at a later stage.”

The decision is about when an appeal may be taken. It does not decide whether section 230 protects any particular claim at trial, and it does not resolve the merits.

Where the state attorneys general claims stand

The states pursue their claims in a separate action coordinated with the MDL, No. 23-cv-05448-YGR. The MDL docket records proposed findings of fact and conclusions of law filed by the state attorneys general on July 31, 2026, an unredacted version on August 15, 2026, and a Meta bench brief concerning objections to trial testimony on August 17, 2026. Case Management Order No. 37 refers to exhibits “admitted in 23-cv-5448” and orders the attorneys general to deliver a thumb drive of those exhibits to the court “for purposes of any enforcement or appellate proceeding” (docket). The documents reviewed for this article contain no findings of fact or conclusions of law entered by the court in that action.

What this does not establish

The record reviewed here contains no verdict, no finding of causation and no approved settlement in MDL 3047. The panel’s transfer order and the complaints it summarizes describe allegations. The Ninth Circuit’s ruling addressed appellate jurisdiction, not whether any platform caused any person’s harm. Case Management Order No. 37 sets a schedule and resolves case management disputes; it does not decide the claims.

A bellwether trial is a test case. Its outcome does not bind plaintiffs whose cases remain in the MDL, and the 3,824 figure counts actions not yet closed or remanded rather than the number actively ready for trial.

Frequently asked questions

Is MDL 3047 a class action?

No. It is a multidistrict proceeding in which individual plaintiffs keep separate cases consolidated for pretrial purposes. See MDL versus class action.

Has a court found that social media causes adolescent addiction?

Not in the documents reviewed here. The transfer order recites allegations about design and warnings, and the dismissal rulings concern the legal sufficiency of claims. Neither is a finding of causation.

What did the Ninth Circuit hold in August 2026?

It dismissed Meta’s and TikTok’s interlocutory appeals for lack of appellate jurisdiction. The panel held that section 230 provides a defense to liability, not immunity from suit, so the ruling can be reviewed after a final judgment.

When are the first trials?

Case Management Order No. 37 lists bellwether trials beginning February 3, 2027, with a pretrial conference on November 13, 2026. The order calls them the Tucson and Charleston bellwether trials.

Is there a settlement in MDL 3047?

No settlement or court-approved resolution appears in the documents reviewed for this article. The docket shows pretrial and trial preparation activity.

Which companies are defendants?

The primary defendants identified in the court documents include Meta and Instagram, TikTok and ByteDance, Google and YouTube, and Snap. Claims against non-primary defendants, including X Corp., Roblox and Discord, are stayed under Case Management Order No. 37.
