MichiganAI regulation

Regulation Status

• Michigan has not enacted a comprehensive or risk-based AI statute and has focused its AI-specific lawmaking on election integrity. In November 2023 the legislature passed a package (Public Acts 263-266 of 2023) amending the Michigan Campaign Finance Act and Michigan Election Law; the two AI-focused measures, HB 5141 (PA 263) and HB 5144 (PA 265), both took effect on February 13, 2024.
• HB 5141 requires political advertisements generated in whole or substantially by AI, including those communicated by phone, radio, or print, to carry a clear disclaimer; the source data does not specify an enforcement mechanism. HB 5144 prohibits distributing materially deceptive AI-generated media within 90 days of an election where the distributor intends to harm a candidate or change voter behavior, unless an appropriate disclaimer is provided; penalties for the deepfake offense include imprisonment, injunctive relief, and fines up to $1,000. On August 26, 2025, the Governor also announced signing legislation addressing AI-generated sexual-exploitation imagery. Michigan has not adopted a comprehensive automated-decision or frontier-model AI statute in the legislative coverage summarized here.
• Executive and agency developments: Attorney General opposes proposed federal preemption of state AI laws: Announces Michigan's participation in a bipartisan coalition of 36 attorneys general opposing proposals to bar state AI laws. The statement emphasizes preserving state consumer-protection and enforcement authority while federal comprehensive protections remain limited.
