AI Compliance for 📢 Marketing & Advertising in Michigan

What this means for Marketing & Advertising in Michigan

Marketing & Advertising companies in Michigan are navigating the intersection of two accelerating trends: the rapid integration of AI tools into content generation, audience targeting, campaign optimization, and sentiment analysis, and a growing body of state law that places direct obligations on businesses that deploy these systems. Whether you generate marketing copy with AI or build predictive audience segments, the regulatory landscape in Michigan has concrete implications for how your business must operate today.

While Michigan does not yet have a dedicated AI law in effect, marketing & advertising businesses operating here are not without compliance obligations. Federal statutes — including FTC Act Section 5 and the FCC Telephone Consumer Protection Act — apply regardless of state law status. If your business serves customers in states with active AI laws, those laws may also reach your operations. Michigan has not enacted a comprehensive AI law. Proposed HB 4668 would require large developers of AI foundation models to implement safety and security protocols to manage critical risks, prescribe developer duties and whistleblower protections, and provide civil sanctions and remedies.

Within the marketing & advertising sector, AI systems commonly scrutinized by regulators include AI content generators, programmatic advertising algorithms, sentiment analysis tools, social media automation, and AI-powered creative testing platforms. MI regulators have called out AI-generated content labeling and synthetic media in advertising as areas of elevated concern under HB 4668 (2025-26). Importantly, these requirements apply regardless of whether a business built the AI system internally or purchased it from a third-party vendor — organizations that deploy AI bear compliance responsibility for the systems they use.

The sector risk classification for Marketing & Advertising is Medium, reflecting the reality that AI-generated marketing materials can mislead consumers, and undisclosed use of AI in persuasive content is a growing regulatory target in multiple states. AI-generated content disclosure increasingly required. Deepfake prohibitions affect marketing materials. In Michigan, businesses that process audience behavioral data, campaign performance records, and customer communication histories through automated decision systems face the greatest exposure. The law's scope, however, typically captures a broad range of operators — not just large incumbents — so smaller marketing & advertising businesses should not assume they are below the regulatory threshold.

The most effective starting point for marketing & advertising businesses in Michigan is an AI inventory: a documented list of every AI system in use, the decisions it influences, and whether those decisions affect individuals in ways the law covers. From there, companies typically need written disclosure notices, a designated internal owner for AI compliance, and a regular review cadence to track the technology and regulatory landscape as both continue to evolve. Disclosure and documentation requirements are often achievable in a matter of weeks; technical controls around bias testing and impact assessment require longer runway. Given Michigan's deadline of TBD, the time to begin is now.
