Does New York SB 8420-A apply to marketing agencies based outside New York?

Yes. The law's trigger is not where the agency is located — it's whether the advertisement is viewable by New York residents. If you produce ads for clients whose content reaches New York audiences (which is virtually any national or regional campaign), your agency must ensure compliant disclosures are in place. Both the advertiser and the producing agency can be held liable.

What counts as a 'synthetic performer' under New York's AI advertising law?

A synthetic performer is a digitally created human figure built or substantially modified using generative AI that appears to be a real person but is not a recognizable, identifiable individual. This includes AI-generated avatars, AI-produced human likenesses in stock-style imagery, and any human figure in an advertisement that was generated by an AI tool rather than photographed or filmed. It does not cover AI tools used to edit or enhance photographs of real, identifiable people — those are addressed under separate New York publicity rights law.

What does 'conspicuous disclosure' mean under SB 8420-A?

The law requires a disclosure that is prominent and unavoidable — not fine print at the bottom of a page. A clearly visible label reading 'Synthetically created performer' or 'AI-generated' placed near or on the AI-generated image is the most defensible approach. The disclosure must be legible and visible in the context in which the ad appears: if it's a digital display ad, the label should appear in the ad itself; if it's a video, an on-screen disclosure or prominent caption is appropriate. Disclosure buried in terms of service or a separate landing page does not meet the standard.

What are the penalties for non-compliance with New York's AI advertising disclosure law?

$1,000 for a first violation. $5,000 for each subsequent violation. Critically, each non-compliant advertisement counts as a separate violation — so if you have 15 client ads in rotation featuring AI-generated human figures without disclosures, the exposure is not $5,000 total. It is $5,000 per ad per violation. For an agency running multiple AI-generated campaigns, non-compliance at scale adds up quickly.

Does SB 8420-A apply to social media ads and digital campaigns, or only traditional advertising?

The law applies to any advertisement viewable by New York residents, which includes digital display ads, social media sponsored posts, video pre-rolls, programmatic placements, and website banners. There is no exemption for digital formats. If a New York resident can see the ad, the disclosure requirement applies.

NY AI Ad Disclosure Law: Agency Checklist

Last December, Governor Hochul signed a law that most marketing agencies have never heard of. In eight days, it takes effect.

New York SB 8420-A — the state's synthetic performer advertising disclosure law — goes live on June 9, 2026. If your agency produces advertising content featuring AI-generated human figures for any client whose ads reach New York audiences, you need a disclosure in place. Not a privacy policy update. Not a terms-of-service clause. A visible label on the ad itself.

This is not a law aimed at AI developers. It is aimed at advertisers and the agencies that produce their creative.

What the Law Actually Requires

New York SB 8420-A requires any advertiser whose content is viewable by New York residents to include a conspicuous disclosure when an AI-generated "synthetic performer" appears in the advertisement.

A synthetic performer is defined as a digitally created human figure built or substantially modified using generative AI that looks like a real person but is not a recognizable, identifiable individual. Think: AI-generated avatars, AI-produced lifestyle imagery with human figures, AI-created spokespersons that don't correspond to a real person. If an AI tool generated the human in the ad — and that human isn't a real, identifiable person — you have a synthetic performer.

What the disclosure must look like: Conspicuous. Prominent. Unavoidable. The law does not specify exact language, but legal guidance from firms like Lowenstein Sandler, Skadden, and Cooley points to language along the lines of "Synthetically created performer" or "AI-generated" placed visibly on or near the image. Fine print at the bottom of a landing page does not meet the standard.

Who it applies to: Both the advertiser and the producing agency. Your client may not know this law exists. Your agency does now. If you produce non-compliant ads for a client, both of you are exposed.

Penalties:

First violation: $1,000
Each subsequent violation: $5,000
Each non-compliant ad counts as a separate violation

Fifteen client ads in rotation with AI-generated figures and no disclosures is not a $5,000 problem. It is a $70,000 problem.

Who This Affects in Your Agency

If you are a marketing agency producing advertising content for clients, run this quick mental inventory:

You are directly affected if:

You use AI image generators (Midjourney, Adobe Firefly, DALL-E, Stable Diffusion) to create human figures in client ads
You license AI-generated stock imagery featuring synthetic human likenesses
You produce video, display, social media, or digital campaigns featuring AI-generated human figures for clients with any New York audience reach

You may not be affected if:

All human figures in your ads are real, identifiable people (models, talent, clients)
You use AI only to edit or enhance photographs of real people — not to generate the human figure itself
Your client's advertising does not reach New York residents (meaning no national campaigns, no programmatic, no social media placements that could appear to NY audiences)

The last category is an extremely narrow carve-out in practice. Most agencies producing national or regional digital campaigns have New York exposure.

The 30-Minute Compliance Checklist

This is not a months-long compliance project. The disclosure requirement is operationally simple. Here is what you need to do before June 9.

Step 1: Audit your current ad production queue (10 minutes)

Pull up every active client campaign your agency is running. For each one, ask: Does any ad in this campaign feature a human figure created by an AI tool?

Look specifically at:

Social media ad creative
Display ad imagery
Video creative featuring human figures
Any stock imagery you sourced from AI-generated stock libraries

Flag every instance where the human figure was AI-generated and is not a recognizable real person.

Step 2: Add the disclosure label to flagged creative (10 minutes)

For each flagged ad, add a visible disclosure. The label should read "Synthetically created performer" or "AI-generated performer" — placed clearly on or near the image. For display ads, embed it in the creative file. For video, add an on-screen text overlay or lower-third. For social media posts, include the disclosure in the post text if the ad format doesn't support embedded labels.

If your agency does not have direct access to the live creative files, contact the client immediately and explain that a disclosure update is required by June 9.

Step 3: Brief your client on the requirement (5 minutes per client)

Send a brief email to each affected client explaining:

New York SB 8420-A takes effect June 9, 2026
Any ad with an AI-generated human figure viewable by NY residents requires a visible disclosure
Your agency has updated the creative or is in the process of doing so
They should confirm with any other agencies producing their ads that the same update is in progress

Document this conversation. An email thread is sufficient. You want a record that you identified the issue, informed the client, and took action.

Step 4: Update your standard production process (5 minutes)

Add one question to your creative brief or production checklist: "Does this ad feature any AI-generated human figures?" If yes, a disclosure label is required before the ad goes live.

This is a one-time process change, not an ongoing audit burden. Build it in now so every future campaign starts disclosure-compliant.

The Bigger Pattern: This Is the First, Not the Last

New York SB 8420-A is the first-in-the-nation synthetic performer advertising disclosure law. It will not be the last. Several other states are actively watching how New York implements this, and the Federal Trade Commission has signaled ongoing interest in AI-generated content transparency in advertising.

For marketing agencies, the compliance posture worth building now is not "how do we respond to each new state law" — it is "how do we make disclosure a default part of our AI creative workflow." For a broader view of how state AI laws are landing across professional services sectors, see our multi-state AI compliance guide. Agencies that build disclosure into production today are ahead of a compliance wave that is still building.

The law is also a useful forcing function for something agencies should be doing anyway: being transparent with clients about when and how AI is being used in their creative work. Clients who discover AI-generated imagery in their campaigns without prior disclosure — through a law, a press story, or a consumer complaint — are more surprised and more upset than clients who were briefed in advance. The disclosure requirement is the floor; the relationship standard is higher.

One Action for This Week

Search your current ad production queue for AI-generated human images or avatars before June 9.

That is the single task. Flag every ad in your active rotation where the human figure was generated by an AI tool and is not a real, identifiable person. Once you have the list, the compliance fix — a visible label — takes minutes per ad.

The window is tight. The ask is minimal. Do it this week.
