A federal court in California has ruled that Meta Platforms can be held liable for fraudulent investment ads generated by its artificial intelligence advertising tools. The decision strips Meta of the immunity typically granted under Section 230 of the Communications Decency Act, which protects online platforms from being sued over content posted by third parties.
Chief Judge Richard Seeborg of the Northern District of California denied Meta’s motion to dismiss the case, Bouck v. Meta Platforms, a class-action securities fraud lawsuit involving penny stocks. The plaintiffs argued that Meta’s generative AI systems actively shaped the fraudulent advertisements, making the company a co-creator rather than a passive host. This ruling follows a similar outcome in Forrest v. Meta, where another judge found that Meta’s AI tools combine images, videos, text, and audio, creating a factual dispute over the platform’s role in developing illegal content.
The key distinction drawn by the court is that targeting an audience is considered protected distribution, but actively generating or transforming ad content is not. By using AI to create advertisements, Meta crosses the line from passive hosting to active development, removing its Section 230 shield.
This case also raises unresolved questions under securities law, specifically Rule 10b-5. The Supreme Court’s Janus Capital decision holds that the entity with ultimate authority over a statement’s content and communication is its maker. If Meta’s AI exercises this authority in assembling investment solicitations, Meta could be held directly liable for securities fraud, with no Section 230 defense available.
Other tech giants face similar risks. Companies like Alphabet, Snap, TikTok, and X deploy generative AI in their advertising systems and could be exposed under the Ninth Circuit’s material contribution test. As AI-driven fraud becomes more common, regulators and plaintiffs are increasingly targeting the infrastructure behind fraudulent content, rather than just the individual perpetrators. Meta has stated it will appeal both decisions, but the legal landscape for AI-generated ads is shifting significantly.
