Colorado AI Act

The Colorado AI Act (SB 24-205), signed in 2024, was the most advanced AI employment-discrimination statute in the United States. It required employers to Conduct algorithmic-impact assessments, maintain risk-management programmes, and disclose AI use in consequential employment decisions including hiring and promotion. On 27 April 2026, a federal magistrate judge stayed the law pending a constitutional challenge brought jointly by Elon Musk's xAI and the US Department of Justice, which argued the statute overreached into interstate commerce.

Colorado's governor responded by replacing SB 24-205 with the weaker SB 26-189, signed in mid-May 2026. The replacement strips out the risk-management obligations, annual impact assessments, and anti-discrimination duties. What survives is a notice-only regime: employers must give pre-use notice of AI in employment decisions and run an adverse-action process. The substantive protections that made the original law distinctive were abandoned entirely.

The Colorado sequence established a template other state legislators will recognise: pass a statute with teeth, face a joint industry-and-federal challenge on constitutional grounds, retreat to a notice-only Shell. The DOJ's participation alongside a frontier-model firm signals a federal preemption posture, treating state AI labour protections as constitutionally suspect under interstate-commerce doctrine. Every comparable bill in other states now faces the same roadmap for dismantling it.
