California’s SB 1050, the synthetic-performer advertising disclosure bill authored by Sen. Ashby, was amended and ordered to third reading on Aug. 19 and is now positioned for a final Senate concurrence vote before the legislature adjourns sine die at end of business Aug. 31, according to a Transparency Coalition AI update published today.

The bill treats it as an unlawful advertising practice to “create and cause to be published” an ad that prominently features an AI-generated figure, voice, or narrator without a clear, conspicuous label using wording substantially similar to “this performance features a synthetic performer” or “no human performer is depicted.” The statute defines “prominently” to include any synthetic performer “in the foreground” demonstrating a product, voicing narration, or reacting to a commercial message. Every medium is in scope: broadcast, streaming, social, digital.

The enforcement architecture is what makes it bite. The Senate Judiciary Committee analysis frames SB 1050 as an update to California’s False Advertising Law, and the CalMatters bill record confirms an FAL violation is already a misdemeanor. A court order finding a violation also bars advertising platforms served with it from continuing to distribute the ad.

Committee posture has been lopsided. Assembly Judiciary approved the bill 9-0. Assembly Appropriations moved it out of suspense 12-1 on Aug. 13.

After concurrence, Gov. Newsom has 30 days to sign or veto. The amended version doesn’t yet specify an effective date, which leaves a narrow but real audit window for the 5-to-30-person consumer brands most likely to be running AI voiceovers or on-camera synthetic figures in paid creative right now. The regulatory posture here’s familiar: California writes the disclosure regime, and the rest of the country’s ad supply chain quietly conforms.
