Governor Jared Polis signed SB24-205 on 17 May 2024, requiring developers and deployers of high-risk AI systems to use reasonable care against algorithmic discrimination (unfair treatment by automated decisions) from February 2026. In August 2025 the start was pushed to 30 June 2026. In May 2026 the state replaced it with SB26-189, a lighter law on automated decision-making that applies from 1 January 2027.
