Colorado narrows its first-in-nation AI law as a federal draft seeks to preempt states

Colorado has rewritten the first comprehensive state AI law in the United States before it could take effect. Governor Jared Polis signed SB 26-189 in May 2026, replacing the original Colorado AI Act and pushing the effective date from June 30, 2026 to January 1, 2027. The rewrite narrows the statute's reach considerably.

The original law, SB 24-205, governed broadly defined "high-risk AI systems." The replacement covers "covered automated decision-making technology" — systems that process personal data to materially influence a consequential decision, per the bill text. Consumers keep the right to disclosure, explanation, correction and meaningful human review of automated decisions in employment, housing, lending, insurance, healthcare, education and essential government services, with a notice required within 30 days when such technology materially influences an adverse decision.

What is gone matters as much as what stays. The rewrite drops the original law's broad reasonable-care duty, its impact-assessment and risk-management regime and its exemptions for federal entities. There is no private right of action; enforcement rests solely with the Colorado attorney general, who must complete rulemaking by January 1, 2027.

The state action lands as Congress weighs whether to override states entirely. On June 4, 2026, Representatives Jay Obernolte and Lori Trahan released a bipartisan discussion draft of the Great American AI Act, which would preempt state laws that specifically regulate AI model development for three years, according to Obernolte's office. The draft does not cover deployment or use, and would require third-party audits of large AI developers.

The proposal is far from law. It is a discussion draft released for public feedback with no scheduled vote, and it drew opposition from labor unions and consumer advocates. Analysts also noted a limit even if it passes: because the preemption targets model development, it would not reach Colorado's deployment-focused rules.

The sequence captures the current standoff — states writing AI rules and then narrowing them, while Washington debates whether to take the pen away.
