Pennsylvania signs the AI Deceptive Advertising Act; AI ad disclosures required from December 21

Pennsylvania Governor Josh Shapiro signed Senate Bill 806, the Artificial Intelligence Deceptive Advertising Act, on October 22, 2026. The measure is Act 99 of 2026 and takes effect 60 days after signing, on December 21, 2026. It bars an advertiser from creating or disseminating an advertisement that uses synthetic content, meaning an image, video, audio clip or text significantly modified or generated by AI, in a way that creates a false consumer perception about the nature, origin or authenticity of the goods or services advertised, unless the ad carries a clear and conspicuous disclosure stating that it contains AI modified or generated content.

The disclosure must appear at the first presentation of the synthetic content, in the same medium as the content, and, where technically feasible, be permanent or extraordinarily difficult to remove. Content limited to text, and content that is evidently fictional or is parody, satire, commentary or criticism, is exempt. There is no private right of action: the attorney general and district attorneys can seek injunctions or civil actions, with a civil fine capped at $3,000 plus attorney fees and court costs. The trigger terms, including "significantly modified" and "false consumer perception", are not defined in the act, and the law applies regardless of where an ad was produced, so national campaigns aired in Pennsylvania are expected to standardize the disclosure rather than geofence it.
