NY Synthetic Performer Law: What Ad Agencies Need to Know Before June 2026

New York Just Set the Hardest AI Ad Deadline in the US

There are few compliance deadlines in advertising that apply equally to a 500-person holding company agency and a five-person boutique — and carry penalties that scale with programmatic volume. The NY Synthetic Performer Law is one of them.

Governor Hochul signed Senate Bill S.8755-A into law in late 2024. The bill amends New York's Arts and Cultural Affairs Law to create explicit protections for performers whose voice, face, or likeness could be replicated using generative AI. For advertising specifically, the effective date is June 2026 — meaning campaigns running on June 1 are subject to the law from day one.

The window to build compliant workflows is closing. Here is what the law actually requires and what agencies need to do before the deadline.

What the Law Requires: Two Parallel Obligations

For advertising, NY S.8755-A creates two distinct compliance requirements that operate independently. Meeting one does not satisfy the other.

1. Written Consent (Pre-Production)

Before any AI-generated replica of a performer's voice or likeness is created or used in an ad, you must obtain:

• A signed written agreement from the performer or their authorized representative
• Agreement terms that specifically describe the nature, scope, and intended commercial use of the replica
• Compensation that is "reasonably consistent" with what the performer would have earned for the actual performance

This applies regardless of whether the performer is living or deceased. Estates of deceased performers retain full standing to enforce these provisions — including where likeness rights have been assigned to rights-holding companies.

2. Prominent Disclosure (At Publication)

At the point of publication, every ad featuring a synthetic performer replica must carry a clearly visible or audible disclosure that meets three standards:

• Conspicuous — not buried in fine print, end-card legal text, or a URL
• Format-matched — audio disclosures for audio ads, on-screen text for video, visible labels for display
• Persistent — not dismissible before a viewer or listener has had reasonable opportunity to receive it

Who Is In Scope

The Synthetic Performer Law's coverage is deliberately broad. It applies to:

• Ad agencies creating AI-generated content on behalf of clients
• Brand in-house creative teams producing their own AI campaigns
• Ad platforms and publishers running synthetic content in paid placements
• Production companies generating AI media under agency or brand contracts

The most important thing to understand about jurisdiction: the law applies based on where the ad is shown, not where the agency is headquartered. A Chicago-based agency serving AI-generated ads to New York residents on streaming, social, or OTT is fully within scope.

What Counts as a "Synthetic Performer Replica"?

The law's definition is intentionally wide, and identifiability is the controlling standard: if a reasonable viewer or listener would associate the synthetic output with a specific, real performer, living or deceased, the law applies.

The Penalty Math

The number that gets compliance teams into the room: $1,000 to $5,000 per violation, where "per violation" means per instance of publication — not per campaign.

Consider the exposure in practice:

• A single AI-generated video ad served across YouTube, Instagram, TikTok, and connected TV? That may be four separate violations.
• A six-week campaign running the same non-consented synthetic voice across 12 markets? The exposure compounds fast.
• A programmatic campaign at scale? The math becomes genuinely alarming.

Statutory damages do not require the plaintiff to prove actual harm — they are available automatically. Performers and rights holders can enforce without complex litigation over lost earnings. Secondary liability is an additional risk: agencies producing non-compliant creative could face indemnification demands from brand clients whose campaigns are challenged.

How the IAB Framework Maps to the NY Law

The IAB AI Transparency and Disclosure Framework (January 2026) was written explicitly to harmonize with New York's requirements. Agencies that adopt the IAB framework as their internal standard will find it substantially easier to demonstrate good-faith compliance with the NY law.

The key alignments:

Disclosure label text: The IAB specifies exact strings — "AI-generated person," "AI-generated likeness," "AI-generated voice" — that are designed to meet the NY standard for "conspicuous disclosure." Using these standardized strings, rather than improvised wording, is the fastest path to defensible compliance.

Format-matched placement: The IAB framework defines placement rules by content type — persistent labels for full-duration video, spoken disclosure before or after AI audio segments (with a twice-required rule for spots over 60 seconds), visual labels adjacent to synthetic personas in display. This maps directly onto the NY law's format-matching requirement.

Materiality thresholds: The IAB's three-prong materiality test — deception potential, material impact, expectation alignment — helps agencies distinguish regulated from exempt content in a documented, repeatable way. If all three prongs are met, disclosure is required, and the IAB's threshold was designed to satisfy the NY law.

C2PA metadata: The IAB endorses embedding machine-readable disclosure assertions in creative assets using the C2PA standard (com.iab.threshold and com.iab.disclosure). While not legally required under the NY law, C2PA metadata creates an auditable record of AI use and good-faith compliance — exactly the kind of documentation that matters in an enforcement proceeding.

Before June 2026, every agency needs to have answered each of these questions for every AI-produced campaign targeting New York.

Run Your Campaigns Through the IAB Materiality Checker

Not sure whether a specific piece of AI creative triggers the NY law? The IAB Materiality Checker at TheAlgoBrief walks you through the three-prong test — deception potential, material impact, expectation alignment — in under 60 seconds. Input your ad format, content type, and the AI tools used in production.

If You Miss the June Deadline

Enforcement under the NY Synthetic Performer Law can be initiated by performers or their estates filing civil actions directly, by the New York Attorney General pursuing systemic or egregious violations, or by rights-holding companies acting under assigned likeness rights. Campaigns running non-compliant synthetic performer content on June 1 are exposed from day one.

A broader jurisdiction comparison: NY is the most immediately urgent US deadline, but it is not the only one.

Building your workflow around the NY law now gets you a compliance foundation that scales directly to California in August and positions you for EU alignment in 2027.

Key Takeaways

The NY Synthetic Performer Law is the most immediately actionable AI advertising regulation on the US calendar. June 2026 is close, penalties are per-use, and the consent requirement imposes pre-production obligations that take time to build into agency workflows.

The IAB AI Transparency and Disclosure Framework gives you the disclosure infrastructure needed to operationalize compliance across formats. Used together, the IAB framework and the IAB Materiality Checker provide a clear, repeatable path from creative brief to compliant publication.
