Abstract
(SB0991 · 103rd Legislature) Trade: consumer goods and services; use of certain algorithms and protected class data to set prices; prohibit. Amends sec. 3 of 1976 PA 331 (MCL 445.903) & adds sec. 3j. Sponsor: Sen. Mallory McMorrow (D) + 12 co-sponsors In committee: S Economic And Community Development Latest action (2026-05-20): Referred To Committee On Economic And Community Development
Why this matters
SB0991 targets a specific consumer-harm mechanism — algorithms trained on or using protected-class data (race, sex, etc.) to set prices — layering an anti-discrimination lens onto Michigan’s broader surveillance-pricing debate. For businesses using dynamic or personalized pricing, this would create new Consumer Protection Act liability tied to how inputs are chosen, not just outputs; for consumers, it establishes a statutory hook against discriminatory algorithmic pricing distinct from general surveillance-pricing bans.
