HB 24-1147 · candidate election deepfake disclosures

The act regulates covered generative AI deepfakes in communications about candidates for elective office. It requires a clear disclosure and prohibits knowing or reckless distribution of a covered deepfake with no proper disclosure. The secretary of state receives complaints; the act also allows a candidate to seek civil relief. Its stated exclusions and proof requirements matter to the scope.

Who should read it: campaign communicators, media buyers, and publishers of candidate-related synthetic media. Exposure: administrative penalties and a candidate's civil claim under the act.

SB 24-205 · current high-risk AI framework

The 2024 act addresses algorithmic discrimination in high-risk AI systems used for consequential decisions. It sets developer and deployer reasonable-care duties, with specified disclosures, risk management, impact assessments, consumer notices, correction and appeal paths, and attorney general enforcement. SB 25B-004 moved the core requirements' start from February 1 to June 30, 2026. SB 26-189 repeals and reenacts this framework on January 1, 2027; its replacement duties should not be read as the current 2024 rules.

Who should read it: developers and deployers of covered high-risk systems and businesses using consumer-facing AI interactions. Exposure: attorney general enforcement under the Colorado Consumer Protection Act, subject to statutory terms and exceptions.

SB 26-189 · automated decision-making technology

Chapter 131 repeals and reenacts the consumer-protection provisions introduced by SB 24-205. Starting January 1, 2027, it addresses covered automated decision-making technology used to materially influence consequential decisions. It provides for developer technical documentation, deployer notices, post-adverse-outcome information, consumer data and human-review requests, record retention, and attorney general enforcement. It covers specified domains including employment, education, housing, financial services, insurance, health care, and essential government services, with defined exclusions.

Current status: enacted, but the main duties are not yet in force as of this review. The act's rulemaking, appropriation, and specified provisions took effect on passage; section 5 sets January 1, 2027 for the rest and applies the act to consequential decisions made on or after that date. Check the enacted text and any rules before implementing a duty.

Scope and method

This is a selected Colorado reference, not a complete inventory of Colorado AI measures. The national directory lists selected provisions already in force; this page also describes one enacted future framework because it changes how the current statute should be read. No pending proposal is presented as law. Rules, litigation, local measures, and other state acts require separate review.

Each link below is an official Colorado General Assembly record. The dates above were checked on September 28, 2026. A source's retrieval date records when it was consulted; this page's update date records this editorial publication. A bill-page summary may retain its original dates after an amendment, so use the later enacted session law and effective clause to resolve timing.
