## 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Its effective date was postponed by a 2025 special-session bill and, before it arrived, SB 26-189 (signed 14 May 2026) repealed and re-enacted the framework as a narrower automated-decision-making-technology law applying from 1 January 2027.

## 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SB 24-205 was repealed and replaced by SB 26-189 on 14 May 2026, before its delayed 30 June 2026 effective date.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.

## What is binding and what is guidance

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