NY AI Synthetic Performers Disclosure Law Takes Effect Monday: What Advertisers Running AI Campaigns Must Do Now

Four days. Monday. That’s the deadline.

New York’s AI Synthetic Performers Disclosure Law, SB-8420A, takes effect June 9. It applies to commercial advertisements featuring AI-generated synthetic human-like models, spokespeople, or background performers that are shown to New York consumers. If your brand is running that kind of campaign and it reaches New York, you need a disclosure in place by Monday.

The law doesn’t specify required disclosure text or format, according to legal analysis from Hunton Andrews Kurth, the source for all specific legal claims in this brief (the primary government URL for SB-8420A is currently non-resolving). Hunton Andrews Kurth advises defaulting to visible on-screen text. The law uses the word “conspicuous” without defining it. Until the state issues formal guidance or enforcement actions create case precedent, “conspicuous” means prominently visible to a reasonable viewer, not a fine-print footer.

Penalties are civil. First violation: $1,000. Subsequent violations: $5,000 per violation, per Hunton Andrews Kurth’s analysis. These are per-violation figures, not per-campaign figures. A national advertising campaign running across multiple placements to New York consumers without the required disclosure isn’t one violation. The math compounds quickly.

Two exemptions apply, according to Hunton Andrews Kurth. First: promotional materials for expressive works, motion pictures, television productions, video games, where the synthetic performer use is consistent with the work itself. If you’re running a trailer for a film that uses AI-generated extras, the exemption may cover that use. Second: audio-only advertisements. No visual component, no disclosure obligation under this law.

Before/after June 9 is the useful frame for compliance teams. Before Monday: any AI-generated synthetic performer in a New York-facing commercial ad runs without a legal disclosure obligation under this specific law. After Monday: every such ad carries a civil penalty exposure if the disclosure is absent. The campaign doesn’t need to change. The disclosure needs to be added.

The practical steps, in order: Audit every active commercial advertising campaign for AI-generated human-like performers, models, spokespeople, background figures, animated human characters that a reasonable viewer would understand as representing a human. Assess whether the campaign reaches New York consumers (digital geo-targeting makes this answerable; broadcast reach makes it less clean). Apply the exemption criteria: is this promotional material for an expressive work? Is the ad audio-only? Where neither exemption applies, add a conspicuous on-screen disclosure before Monday.

The catch is that “AI-generated” isn’t always a clean category in production workflows. Composited imagery, digitally altered human talent, and fully synthetic figures sit on a spectrum. Hunton Andrews Kurth’s analysis doesn’t resolve that production-layer ambiguity, nor does any publicly available guidance as of this brief. Compliance teams should consult legal counsel on where their production workflows fall, not assume the answer.

The legislative text of SB-8420A provides the primary authority. The Hunton Andrews Kurth analysis is the strongest currently available secondary source; all specific claims in this brief are attributed to that analysis. Compliance teams should review the primary text directly once a resolving URL is available.

New York isn’t alone. This law is one node in a state-level synthetic content disclosure pattern that includes California and Texas and connects directly to the Copyright Office’s finding that Congress needs to act on deepfakes. The companion deep-dive for addresses the full multi-state pattern and its implications for national advertisers.
