Colorado AI Act
The template for US state comprehensive regulation and the first law actually halted under the federal preemption push. Its litigation-driven rewrite shows how fragile state AI regimes are while DOJ contests them.
What it is
The first comprehensive US state AI law, now re-enacted: developers and deployers of AI used in consequential decisions (employment, lending, housing, healthcare) owe duties against algorithmic discrimination, with documentation, notices and Attorney General rulemaking. The original 30 June 2026 start never took effect after a court suspended enforcement; the replacement law applies from 1 January 2027.
Enforcement of the original SB 24-205 was suspended by court order on 27 April 2026 (X.AI v. Colorado, with DOJ intervening). In May 2026 SB 26-189 repealed and re-enacted the law as an automated decision-making technology act effective 1 January 2027.
