Key Requirement
The most comprehensive US state AI law. As amended by SB 26-189 (2026) it takes effect January 1, 2027 and centers on transparency/disclosure for consequential automated decisions (the original algorithmic-discrimination duty of care was repealed). Attorney General rulemaking is underway; no final rules have been published yet.
Employers must notify employees when AI assists in hiring, reviews, promotions, or discipline, and may not use AI that discriminates against protected classes (including via ZIP-code proxies).
