US appeals court declines to halt thousands of lawsuits over social media addiction against Meta (META), TikTok and others

The ruling is procedural rather than a merits judgment: an appeals court declining to halt a consolidated docket means the mass-tort machinery proceeds toward discovery, bellwether selections and eventual test trials, the sequence that has defined prior product-liability waves against large US corporates. In comparable episodes, equity impact has tended to arrive in stages rather than at the headline: an initial re-rating of legal risk at the defendant, followed by a longer drift as bellwether outcomes and any settlement architecture take shape, with the peer set named in the suits moving together. The relevant distinction for the named platforms is between defendants with deep cash generation able to absorb settlement or judgment costs and smaller co-defendants where the same liability overhang weighs more heavily relative to balance sheet. Discovery in cases of this kind has historically been the phase that produces headline risk, since internal documents on product design and internal research have tended to surface and shape both the legal posture and the political and regulatory backdrop around child safety. Worth noting is the calendar of follow-ons: trial scheduling, any motions to dismiss at the merits stage, and parallel state-level or legislative actions that have on past occasions compounded the pressure beyond the courtroom. As a procedural decision, the read is that the overhang extends rather than resolves.
