One Jury, Two Teens, Three Defendants: Judge Kuhl Consolidates the October Social Media Addiction Trial

What Judge Kuhl decided, and why

The defendants opposed trying the two cases together, arguing that two plaintiffs with different histories, different platforms, and different injuries would confuse a jury. Judge Kuhl disagreed. According to Beasley Allen's account of the order, she found that California law supports consolidation in mass tort cases and that proper trial management will allow jurors to distinguish between the plaintiffs' individual circumstances. Lawsuit Information Center's summary of the ruling puts it more plainly: the differences could be managed without confusing the jury.

Plaintiffs' counsel Mark Lanier, who tried K.G.M., told the court the cases involve similar allegations that social media platforms caused mental health injuries to adolescent users and can be presented together without confusing jurors. The practical argument for consolidation is efficiency: much of the evidence in these cases is about how the platforms were designed, not about any one plaintiff, and the same corporate witnesses and internal documents would otherwise be presented twice. Beasley Allen noted the combined trial reduces demands on witnesses such as Meta CEO Mark Zuckerberg, who testified in the K.G.M. trial in February.

Who is left in the case

Three plaintiffs were set for October. Now there are two. S.J. is a 15-year-old from Illinois; K.D.B. is an 18-year-old from Mississippi. Both were part of the group of California bellwethers that TikTok settled on confidential terms in the first days of August, and both are proceeding against the three remaining platform defendants: Meta, over Instagram and Facebook; Google, over YouTube; and Snap, over Snapchat.

The third plaintiff, P.M.Y., a 15-year-old from New Jersey, took a different path. After resolving her claims against TikTok, she dismissed her remaining claims against Meta, Google, and Snap rather than proceed to trial against them. Bloomberg Law reported the dismissal on August 20. No payment from the three remaining defendants has been reported, and no reason for the dismissal has been made public. It is the second time in this coordination that a bellwether plaintiff has exited claims against Meta without a reported payment: in July, the second bellwether plaintiff, R.K.C., dismissed his Meta claims after settling with Google, TikTok, and Snap.

TikTok's record is now complete. It settled with K.G.M. on January 27, the day jury selection was to begin; it settled with R.K.C.; and it settled with S.J., P.M.Y., and K.D.B. in August. TikTok has not let a California addiction-injury jury hear a case against it.

Why this trial matters more than the first one

K.G.M. was the proof of concept. A Los Angeles jury found on March 25, 2026 that Meta and Google were negligent in the design of their platforms and awarded $6 million, split $3 million in compensatory damages (Meta 70 percent, Google 30 percent) and $3 million in punitive damages. Judge Kuhl denied the defendants' motions for judgment notwithstanding the verdict and for a new trial on June 9. Meta filed its notice of appeal in July, and Google (YouTube) filed its own days later.

The October trial is the first test of whether that result repeats. Two plaintiffs instead of one, a jury that will hear two different fact patterns against the same design evidence, and three defendants who have now watched the states extract a court-ordered redesign of Instagram and Facebook from Meta in the federal case. The settlement Meta reached with the state attorneys general on August 26 released only the states' claims; it expressly preserved the personal-injury cases, and it did nothing to change the October calendar.

For the roughly 3,300 cases in the California coordination and the 3,208 pending in the federal MDL, a second plaintiff verdict would strengthen the hand of every claimant in settlement talks; a defense verdict would do the opposite. Neither outcome would set an amount any individual case is worth. There is still no global settlement and no per-person payout in this litigation, and any dollar figure presented as one is an estimate.

The federal calendar behind it

The California trial runs alongside a federal schedule that is now focused on the school-district track. The official MDL-3047 document site lists a case management conference before Judge Yvonne Gonzalez Rogers on September 21, 2026, a hearing on X Corp's motion to strike the short-form complaints naming it on September 29, a first school-district pretrial conference on November 6 and a second on December 14, and school-district bellwether jury selection beginning February 3, 2027 with trial to begin February 8. The court notes that it may change any of those dates.

What it means for families with a claim

A bellwether is a test case, not a deadline and not a closing bell. The October trial involves two plaintiffs; everyone else's case continues in the coordination or the MDL on its own track, and new cases continue to be filed each month (the federal docket grew by 71 in the September JPML report). What the trial changes is leverage, not eligibility.
