# Colorado Senate Bill 26-189: Automated Decision-Making Technology (replacement of the Colorado AI Act) - **Record type**: Policy instrument - **Jurisdiction**: Colorado (United States) - **Instrument type**: Act / statute - **Status**: Adopted - **Binding**: Yes - **Issuing body**: Colorado General Assembly - **Adopted**: 2026-05-14 - **Published**: 2026-05-14 - **Applies from**: 2027-01-01 ## In brief The Colorado ADMT law (SB 26-189) is a binding act of Colorado (United States), issued by Colorado General Assembly. It was adopted on 14 May 2026 and applies from 1 January 2027. Applies to developers and deployers of automated decision-making technology used to make, or to materially influence, consequential decisions about Colorado residents. ## Summary 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. ## Scope Applies to developers and deployers of automated decision-making technology used to make, or to materially influence, consequential decisions about Colorado residents. Exemptions and thresholds follow the enrolled bill, which a reviewer must read; secondary reporting describes exemptions for certain regulated financial institutions and federally approved systems. Enforcement is by the Colorado Attorney General. ## Who it applies to Developers and deployers of automated decision-making technology that materially influences consequential decisions about Colorado residents. ## What organisations must do Inventory the automated tools that influence consequential decisions about Colorado residents; give consumers notice before such a tool is used; when an outcome is adverse, tell the consumer that the technology was used, the principal reasons, and how to seek meaningful human review; keep records of those decisions for three years; and, as a developer, supply deployers with the documentation the statute lists. ## Key dates Signed 14 May 2026; applies to consequential decisions made on or after 1 January 2027 (pending review against the enrolled bill). ## Penalties Enforcement by the Colorado Attorney General under the Colorado Consumer Protection Act, according to secondary reporting, with no private right of action. Confirm the enforcement provisions against the enrolled bill. ## Notes on dates Effective date and the "consequential decisions made on or after" formulation come from secondary reporting on the enrolled bill; confirm on the Colorado General Assembly site. ## Obligations recorded against this instrument (5) - **Notify consumers before automated decision-making technology influences a consequential decision** — Deployers must tell a consumer, before the decision is made, that automated decision-making technology will be used to make or materially influence a consequential decision about them.
