Summary
Repeals and reenacts the Colorado AI Act as a narrower, disclosure-based law on automated decision-making technology (ADMT) that materially influences consequential decisions in education, employment, housing, lending, insurance, health care and government services. Developers must document systems for deployers. Deployers must give point-of-use notice and a plain-language explanation within 30 days of an adverse outcome. Consumers get data correction and meaningful human review. Enforcement is by the Attorney General, with a 60-day cure period.

Status notes
Introduced in the Senate on 1 May 2026; passed the Senate on 7 May 2026 (34-1) and the House on 9 May 2026 (57-6), and the Senate concurred in the House amendments on 12 May 2026. Approved on 14 May 2026 (Session Laws 2026, chapter 131). The act takes effect on 1 Jan 2027 and applies to consequential decisions made on or after that date; its rule-making provisions, a joinder clause and the appropriation took effect on passage. The Attorney General must adopt rules on post-adverse outcome disclosures and on the consumer rights to correction and human review by 1 Jan 2027, and may adopt rules clarifying 'materially influence'. The 60-day notice-and-cure provision is repealed on 1 Jan 2030, and annual enforcement reports begin in January 2028. The act creates no new private right of action and allocates fault between developers and deployers in discrimination actions by relative fault.

Recheck of 18 Oct 2026: re-read the leg.colorado.gov page for SB26-189 and the two PDFs stored on 11 Oct 2026, the revised bill (second-reading version in the second house) and the session law (Session Laws 2026, chapter 131). The page now shows the Governor's signature on 14 May 2026 and the session law ends 'Approved: May 14, 2026', which settles the signing date that version 1 took from law-firm sources (one of which gave 20 May 2026). Section 5 of the session law gives the effective date of 1 Jan 2027 and lists the provisions that took effect on passage. The Governor's name is not in the stored files; issuing_body keeps it from version 1. On 17 Oct 2026 robots.txt of leg.colorado.gov disallowed the two PDF download paths, so the copies of 11 Oct 2026 were used.
