Background
In the first social media addiction case to reach a jury verdict in the coordinated Social Media Cases proceeding (JCCP 5255), a Los Angeles jury found Meta Platforms, Inc. and Instagram, LLC (collectively, Meta) and Google LLC and YouTube, LLC (collectively, YouTube) liable to plaintiff K.G.M. on negligence and negligent failure-to-warn theories. The jury awarded $3,000,000 in compensatory damages — allocating 70% of the responsibility to Meta and 30% to YouTube — plus punitive damages of $2,100,000 against Meta and $900,000 against YouTube.
Meta and YouTube each moved for judgment notwithstanding the verdict and for a new trial. Meta’s 50-page memorandum led with Section 230 and the First Amendment, then challenged the sufficiency of the evidence, the punitive damages award, the jury instructions and verdict form, several evidentiary rulings, and the inclusion of Instagram, LLC as a defendant. YouTube principally attacked the punitive damages award, while acknowledging it raised Section 230 “for the purposes of preserving arguments for appeal.” In a 26-page ruling issued June 9, 2026, Judge Carolyn B. Kuhl denied both motions in full.
Section 230: Design Features Are Not Publishing
The court again rejected Meta’s contention that the verdict holds it liable for publishing third-party content. There was “substantial evidence that Plaintiff was harmed by the design features of Instagram, regardless of any of the content found on that platform,” and the jurors were pre-instructed, instructed mid-trial, and instructed at close that they could not base liability on protected publishing activity — including recommending third-party content. The court refused to adopt a “but-for” content test: a claim is not barred by Section 230 merely because third-party content is one but-for cause of the harm, and the fact that a feature like infinite scroll “impelled a user to continue to consume content” does not immunize the feature itself. The court noted recent agreement from other jurisdictions, citing Commonwealth v. Meta Platforms, Inc. (2026) 497 Mass. 384 and TikTok, Inc. v. Eighth Judicial District Court (Nev. 2025) 578 P.3d 640, while observing in a footnote that the Third Circuit’s Anderson v. TikTok goes further than current California law by holding Section 230 inapplicable even to affirmative recommendations of harmful content to minors.
First Amendment: No Evidence That Algorithms Convey Meta’s Message
Relying on Moody v. NetChoice, LLC (2024) 603 U.S. 707, Meta argued its design features are protected expression. The court held Moody inapposite: addictive design features “cannot be analogized to how a publisher chooses to make a compilation of information,” and Moody itself reserved the question of algorithms that respond solely to user behavior “without any regard to independent content standards.” Critically, Meta “presented no evidence of how its algorithm works” beyond conceding it serves users content their prior usage suggests will keep them on the platform — and the burden of proving the factual basis for a First Amendment defense was Meta’s. The court likewise rejected Meta’s compelled-speech attack on the failure-to-warn verdict under NIFLA: health and safety warnings about a commercial product are permissible, and although Meta designated experts to testify that social media addiction lacks scientific support, “none of those experts testified at trial.” Free Speech Coalition v. Paxton was distinguished because Meta made no showing that the verdict burdens adult users’ access to speech.
Sufficiency, Causation, and the Continuing Duty to Warn
The court found the verdict amply supported: Dr. Lembke’s general-causation testimony that Instagram’s design features cause addiction in minors; specific-causation testimony from Dr. Bagot that the features were a substantial factor in K.G.M.’s harm to a reasonable degree of medical certainty; treating-therapist testimony linking the harms to social media use; and Meta’s own internal documents showing employee awareness that its features harmed children. Plaintiff was not required to quantify the share of harm attributable to Meta, and the court reiterated that juries “may determine emotional distress damages without testimony from an expert.” On failure to warn, the court rejected Meta’s argument that any duty froze when K.G.M. joined Instagram in 2015: “Meta did not sell a stagnant product that stayed in the form in which it was purchased,” and as the platform grew more addictive, a duty to warn of the new dangers arose. The court also dispatched Meta’s industry-custom defense — “[t]he fact that other social media companies may have also engaged in unreasonable conduct does not immunize Meta from negligence liability.”
Punitive Damages Stand Against Both Defendants
As to Meta, the evidence showed it designed Instagram to be addictive in pursuit of user time, knew at the highest corporate levels that its features harmed minors, suppressed research into those harms, and failed to warn users or parents — sufficient to establish conscious disregard under Civil Code section 3294. As to YouTube, jurors could conclude from YouTube’s own internal documents that “its intention was to design an addictive platform, with a goal of ‘viewer addiction.’” YouTube’s rejoinder that “addiction” was used colloquially was, the court held, “a quintessential jury issue.”
Instructions, Evidence, and Instagram, LLC
The court stood by its Section 230 instruction and its refusal of Meta’s proposed First Amendment instruction, which would have “invited the jurors to make lay judgments about what may and may not be protected speech.” It rejected the demand for a feature-by-feature verdict form: plaintiff was entitled to try the case on “the overall architecture of the Instagram platform.” Evidence of ineffective age verification was properly admitted — there was evidence K.G.M. began using Instagram at age 9, and that Meta knowingly failed to enforce its publicly announced under-13 ban. Cyberbullying evidence was admitted for the limited purpose of showing addiction (plaintiff kept returning despite bullying), with a limiting instruction. Finally, Instagram, LLC’s eleventh-hour claim that it does not own or operate Instagram was deemed an argument “induced by Meta’s own litigation conduct” — Meta itself proposed instructions treating the defendants collectively — and in any event the testimony of Instagram head Adam Mosseri sufficed to support the entity’s liability.
Key Takeaways
- The first social-media addiction bellwether verdict survives post-trial review intact — compensatories and punitives against both Meta and YouTube.
- Design-feature liability continues to thread the Section 230 needle in California: platform architecture (infinite scroll, filters, notifications, likes, autoplay) is the defendant’s own conduct, not third-party content publishing.
- Moody v. NetChoice is no safe harbor without proof: a platform invoking the First Amendment for its algorithms must put on evidence that they embody expressive choices — Meta’s decision not to call its designated experts proved costly.
- The duty to warn evolves with the product: continuous feature updates can create new warning obligations long after a user signs up.
- Industry-wide practice is not a defense; conformity with other platforms’ design choices does not establish ordinary care.
Why It Matters
Thousands of coordinated cases — in JCCP 5255 and the parallel federal MDL — assert the same design-defect and failure-to-warn theories pressed here. Judge Kuhl’s ruling is the first to validate those theories all the way through a jury verdict, post-trial motions included, and it provides a detailed roadmap distinguishing Moody, Paxton, NIFLA, and NetChoice v. Bonta in the design-feature context. Appellate review is a certainty, and the ruling’s careful record — repeated Section 230 limiting instructions, an evidentiary burden placed on the platforms’ First Amendment defense, and punitive awards grounded in internal documents — frames the issues the Court of Appeal (and likely the California Supreme Court) will confront. For platforms, the message is immediate: design-feature claims by minor users are reaching juries in California, and juries are awarding punitive damages.
