AI-Generated Advertising: The New Legal Landscape for Agencies

Advertising agencies have embraced AI-generated content rapidly — for good reason. The efficiency gains in creative production are substantial. But the regulatory landscape has shifted faster than many agencies anticipated, and the legal obligations around AI-generated advertising are now material.

The Regulatory Landscape for AI Advertising

EU AI Act: The Act's transparency obligations apply directly to AI-generated advertising content. Ads that use AI-generated or significantly AI-modified imagery, video, or audio must carry machine-readable provenance signals. The August 2026 enforcement date is approaching.

California SB 942: In effect since January 1, 2026, requires latent provenance disclosures on AI-generated content — including advertising — distributed to California audiences. Given California's market size, this is effectively a national US requirement for any significant advertising campaign.

FTC Guidance: The Federal Trade Commission has issued guidance making clear that AI-generated endorsements and testimonials are subject to the same disclosure requirements as any other form of paid or incentivized endorsement. Synthetic influencers and AI-generated customer testimonials require explicit disclosure.

South Korea and India: Both markets require disclosure labeling on AI-generated advertising content, with specific provisions for synthetic media depicting real individuals.

The Agency Liability Question

One of the more complex questions in AI advertising compliance is liability allocation. When an agency produces AI-generated content for a client, who is responsible for provenance compliance — the agency or the brand?

The emerging answer is: both, depending on the jurisdiction and the specific obligation. The EU AI Act creates obligations for deployers — organizations that deploy AI systems to produce content. California SB 942 creates obligations for the companies whose AI systems generated the content. Both frameworks create potential exposure for agencies that produce non-compliant content on behalf of clients.

The practical implication: agencies need provenance infrastructure that generates compliant records for client work, and contracts need to address compliance responsibility explicitly.

What Compliant AI Advertising Looks Like

For agencies deploying AI in creative production, compliance requires:

• Provenance at creation: Every AI-generated or AI-modified asset exits the production workflow with a C2PA manifest documenting the AI tools used and the human oversight applied
• Client attribution: Manifests should attribute content to the brand client, not the agency's infrastructure provider — requiring white-label provenance capability
• Disclosure metadata: AI involvement must be recorded in the manifest in a way that satisfies multi-jurisdictional disclosure requirements simultaneously
• Retention: Provenance records must be retained for the periods required by applicable regulations (five years under California SB 942)

The White-Label Requirement

For agencies, white-label provenance infrastructure isn't optional — it's necessary. Client content must carry the client's brand identity in the provenance manifest, not the agency's tool stack. This requires an infrastructure partner capable of issuing C2PA credentials under the client's organizational identity.
