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.

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.
