Overview

Colorado enacted the first comprehensive US state law on algorithmic discrimination, Senate Bill 24-205 (the Colorado Artificial Intelligence Act), signed on 17 May 2024. It imposes a duty of reasonable care on developers and deployers of "high-risk" AI systems that make or substantially influence consequential decisions in areas such as employment, lending, housing, education, healthcare, insurance and government services. Its effective date was postponed by a 2025 special-session bill and, before it arrived, SB 26-189 (signed 14 May 2026) repealed and re-enacted the framework as a narrower automated-decision-making-technology law applying from 1 January 2027.

What is the current regulatory status?

SB 24-205 was repealed and replaced by SB 26-189 on 14 May 2026, before its delayed 30 June 2026 effective date. The replacement law, built around automated decision-making technology in consequential decisions, applies from 1 January 2027 and is enforced by the Colorado Attorney General. Recorded from secondary reporting on 26 September 2026, pending review against the enrolled bill.

Binding rules versus guidance

Binding: SB 24-205 as amended. The Attorney General may adopt rules; none were confirmed at the last check.

Key policy instruments

Colorado (United States) Act / statute Repealed Binding

Colorado AI Act

Colorado Senate Bill 24-205: Consumer Protections for Artificial Intelligence (Colorado AI Act)

The Colorado AI Act requires developers and deployers of high-risk AI systems to use reasonable care to protect consumers from known or reasonably foreseeable risks of algorithmic discrimination. High-risk systems are those that make, or are a substantial factor in making, consequential decisions about education, employment, financial or lending services, essential government services, healthcare, housing, insurance or legal services. Deployers must run risk-management programmes and impact assessments, notify consumers, and explain adverse decisions; developers must document systems and disclose known risks.

Colorado ADMT law (SB 26-189)

Colorado Senate Bill 26-189: Automated Decision-Making Technology (replacement of the Colorado AI Act)

SB 26-189 replaces the Colorado AI Act's regulation of "high-risk" AI systems with duties that attach when automated decision-making technology materially influences a consequential decision about a Colorado consumer in areas such as employment, lending, housing, education, healthcare, insurance and government services. It drops the earlier duty of reasonable care, the mandatory risk-management programme, impact assessments and Attorney General notification, and substitutes advance notice to the consumer, disclosure after an adverse outcome, meaningful human review, three-year record keeping and developer documentation obligations.
