California has enacted a disclosure rule for advertisements that prominently use performers created with generative AI. Senate Bill 1050 requires viewers to be told when the apparent human performance is synthetic—but it is a transparency law, not a general ban on AI performers.
The scope matters: SB 1050 applies to commercial advertising for goods and services when a synthetic performer is prominent. It does not create a universal label for every AI-assisted image, every film, or every piece of promotional material.
What happened
Governor Gavin Newsom approved SB 1050 on September 16, 2026, and the measure was filed with California’s secretary of state the same day as Chapter 246. State Senator Angelique Ashby authored the bill, and SAG-AFTRA sponsored and helped develop it.
Once operative, the new law will make it an unlawful advertising practice to create and cause the publication of an advertisement that prominently includes a synthetic performer without a clear and conspicuous disclosure. The chaptered text suggests wording such as “this performance features a synthetic performer” or “no human performer is depicted.”
What counts as a synthetic performer
SB 1050 defines a synthetic performer as a digital figure, voice, or representation created in whole or in part with generative AI that gives the realistic impression of a human performance but is not recognizable as a specific natural person.
The bill treats that performer as “prominent” when the figure is in the foreground demonstrating a product or service, provides or voices the narration or commercial message, or illustrates or reacts to that message. The disclosure must be difficult to miss, easy to understand, and suited to the format and context of the ad.
That definition is narrower than the rules governing a digital replica of an identifiable actor. California already has separate protections involving performer likenesses and contract consent. SB 1050 addresses the different situation in which an advertisement presents an apparently human salesperson, spokesperson, or voice that is not an identifiable real person.
What the law does—and does not—require
The law requires disclosure; it does not prohibit the creation, distribution, or exhibition of synthetic content. It also does not set a performer pay scale, create a blanket consent regime, or guarantee work for a human performer.
Two exclusions are especially relevant to filmmakers. The rule does not apply to advertising for expressive works—including motion pictures, television programs, streaming content, documentaries, and video games—when the synthetic performer’s use in the promotion is consistent with its use in the underlying work. It also excludes generative-AI use limited to language translation of a human performer or other accessibility features.
Those exclusions are fact-specific. A trailer accurately reflecting a synthetic character in a film is not the same as a separate product advertisement fronted by a synthetic spokesperson. Productions and agencies should obtain advice on their own campaigns rather than treating the expressive-work exception as a universal pass.
What it means for actors and production teams
For performers, the disclosure rule is intended to create a visible distinction between a human performance and a fully synthetic one in covered ads. That can make casting choices more legible to audiences, but disclosure alone does not resolve the larger questions of consent, compensation, training data, or displacement.
For producers, agencies, editors, VFX teams, and post supervisors, covered AI use will carry an additional delivery and review question: does the finished ad prominently present a synthetic performer, and if so, is the disclosure clear in every version and format? The bill covers audio, video, audiovisual messages, online platforms, streaming services, broadcasters, publishers, and other advertising media reaching California consumers.
The enforcement mechanism is also narrower than a general platform-monitoring duty. An advertising medium must stop distributing a violating ad after a court of competent jurisdiction issues an order and the medium is served with that order plus enough information to identify the ad.
What happens next
Advertisers and production vendors will need to translate the statutory standard into practical review steps for scripts, casting, voice generation, finishing, captions, and platform deliveries. Courts and enforcement agencies will eventually clarify how “clear and conspicuous” works across different screens and audio formats.
California is the second state, after New York, to enact this type of synthetic-performer disclosure for advertising. The two laws add momentum to a state-by-state framework while federal proposals on digital likeness and synthetic media remain a separate debate.
