California Governor Newsom signs AI chatbot, synthetic performer and AI transparency laws, Sept.-Oct. 2026
Governor Gavin Newsom signed a package of AI bills in September 2026. On September 10 he signed five of them into law: AB 1709, AB 2246, AB 1856, SB 867, and SB 1119, known as Adam's Law, which expands California's rules for companion chatbots used by children. SB 1000, authored by Sen. Becker, took effect immediately on September 30 as an urgency statute. It removes the 1 million-monthly-user threshold from the California AI Transparency Act's definition of "covered provider," extending disclosure duties to any publicly accessible generative AI system in the state. It also eliminates the requirement that providers offer users the option to include a manifest disclosure in AI-generated content. AB 2713, authored by Asm. Wicks, requires large platforms to show users whether content was AI-generated. On September 16 Newsom held a ceremonial signing of SB 1050, which regulates AI-generated "synthetic performers" in advertising, at SAG-AFTRA's Los Angeles headquarters. On September 28 he signed AB 1609, authored by Asm. Zbur. Starting January 1, 2027, businesses with more than $500 million in national gross annual revenue cannot represent a customer service chatbot as human and must clearly disclose its AI nature when a reasonable person would likely be misled.
