On September 16, 2026, California Governor Gavin Newsom signed SB 1050 into law, which establishes new disclosure requirement for advertisements that prominently use AI-generated “synthetic performers.” When the law takes effect on January 1, 2027, advertisers, agencies, production partners, and media distributors will need to assess California-directed audio and video campaigns for covered AI-generated human figures or voices and provide a clear, conspicuous disclosure—or face false-advertising exposure and potential private litigation.
What Types of Ads are Covered?
SB 1050 makes it unlawful to create and cause the publication of an advertisement that prominently includes a synthetic performer without a clear and conspicuous disclosure. A “synthetic performer” is a digital figure, voice, or representation created wholly or partly using generative AI that realistically appears to be a human performer but is not an identifiable natural person.
The “prominence” standard reaches does not necessarily embrace any digital actor shown on screen. It covers a synthetic performer used in the foreground to demonstrate or illustrate a product or service, to deliver narration or a commercial message, or to illustrate or react to that narration or message.
In other words, the statute is directed at AI-generated or enhanced human-seeming spokespersons, voices, presenters, and other performers used to sell goods or services. It does not appear to regulate every use of generative AI in advertising—for example, an ad’s AI-generated background image may fall outside the law if it does not constitute a prominent synthetic performance. Likewise, the law does not cover AI-generated characters that cannot pass as human beings, such as animals or animated figures.
Ads and Media Covered
The disclosure obligation applies to audio and audiovisual advertisements disseminated to consumers in California through broadly defined “advertising media.” Covered channels include:
- Broadcast television and radio
- Cable operators
- Online platforms and social-media advertising
- Streaming services
- Digital advertising networks
- Publishers and other entities distributing audio or audiovisual ads to California consumers
The law therefore has broad operational consequences for national campaigns. A brand, agency, production company, publisher, platform, or media buyer may need a California-specific compliance review whenever an ad featuring a realistic AI-created person or voice is shown or heard in California.
Required Disclosure
The disclosure must be “clear and conspicuous,” meaning it must be difficult to miss and presented so a reasonable consumer would notice, read, and comprehend it. SB 1050 provides safe-harbor-style wording substantially similar to: “This performance features a synthetic performer” or “No human performer is depicted.”
The statute’s focus on audio and audiovisual media raises implementation issues that advertisers should resolve before launch. For video ads, the disclosure should be visually prominent and sufficiently timed for consumer comprehension; for audio-only ads, a spoken disclosure will likely be necessary to provide a meaningful equivalent. Those choices should be documented in campaign-approval records.
Enforcement Structure
SB 1050 expressly provides that a violation constitutes a violation of California’s False Advertising Law, Business and Professions Code section 17500, and may be enforced under the California Unfair Competition Law (UCL), Business and Professions Code section 17200 et seq.
That enforcement structure matters because the UCL permits private plaintiffs to seek restitution and injunctive relief if they establish standing, which usually requires an injury in fact and a loss of money or property caused by the challenged conduct. The statute also authorizes orders stopping continued use of advertising found to violate the law, and advertising media served with a court order may have to cease transmission of the offending ad.
Class Action Risk
SB 1050 does not establish a fixed per-violation civil penalty or an express statutory-damages award for individual consumers. That omission may constrain cases in which a plaintiff cannot plausibly allege a concrete economic loss, but it does not eliminate private enforcement risk.
Instead, the principal litigation path is likely a representative UCL and false-advertising case alleging that consumers purchased, paid more for, or otherwise lost money or property because an undisclosed synthetic performer rendered the advertising deceptive or misleading. Plaintiffs may also test related claims under the Consumers Legal Remedies Act, depending on the product, transaction, alleged deception, and available remedies.
Class actions remain a realistic possibility despite the absence of a clearly stated damages remedy. A standardized ad campaign, uniform omission of the disclosure, and statewide dissemination create familiar ingredients for putative class allegations; plaintiffs may seek injunctive relief, restitution, and attorneys’ fees where another applicable claim permits them.
Practical Compliance Steps
In light of the rapidly approaching January 1, 2027, effective date, advertisers using generative AI should implement a prepublication review process for California-facing audio and video campaigns:
- Identify whether a human-like figure, voice, or representation is AI-generated in whole or in part.
- Determine whether that performer is prominent under the statute’s foreground, narration, commercial-message, or reaction criteria.
- Add a disclosure that is difficult to miss, consumer-comprehensible, and appropriately adapted to the medium.
- Retain substantiation records showing the origin of the performance, the disclosure format, placement, duration, and campaign versions.
- Address the obligation in agency, production, influencer, platform, and media-buying agreements through AI-use warranties, approval rights, indemnities, and takedown cooperation provisions.
- Monitor pending judicial interpretation, particularly standing, causation, restitution, and class-certification issues under the UCL.
SB 1050 should be viewed as a disclosure and litigation-risk statute rather than merely a labeling rule. Its broad media coverage, incorporation into California’s false-advertising framework, and potential use in UCL-based class actions make compliance especially important for advertisers relying on AI-created human voices or likenesses.
