Key takeaways

Colorado Governor Jared Polis signed SB 26-189 into law on May 14, 2026.

The new legislation explicitly repeals and replaces the prior Colorado Artificial Intelligence Act (SB 24-205).

The new regulatory framework is officially titled the Colorado Automated Decision-Making Technology in Consequential Decisions Bill, or the ADMT Act.

The statutory requirements under the ADMT Act are scheduled to take effect on January 1, 2027.

Legal media first reported on this major legislative development on or about June 8, 2026.

The Legislation

On May 14, 2026, Colorado Governor Jared Polis signed SB 26-189 into law, fundamentally altering the state's approach to regulating artificial intelligence. The new legislation explicitly repeals and replaces the state's previous regulatory framework, which was established under SB 24-205 and known as the Colorado Artificial Intelligence Act.

In its place, the legislature enacted the Colorado Automated Decision-Making Technology in Consequential Decisions Bill, commonly referred to as the ADMT Act. The new statutory regime is scheduled to take effect on January 1, 2027. Legal media first reported on this major legislative development on or about June 8, 2026. By replacing the prior framework entirely, Colorado lawmakers have signaled a definitive shift in how the state intends to govern automated systems that impact its residents. The May 14, 2026, signing date initiated a countdown for developers and deployers of automated systems operating within the jurisdiction to adjust their compliance strategies.

Why It Matters

Repealing a major technology regulation and replacing it with an entirely new framework demonstrates the difficulty states face when attempting to govern rapidly advancing software. The original Colorado Artificial Intelligence Act represented an early attempt to establish guardrails for artificial intelligence. By discarding that framework in favor of the ADMT Act, the legislature indicates that early statutory models may require complete overhauls rather than minor amendments.

State-level regulation often serves as a testing ground for broader national policies. When a jurisdiction as active in technology regulation as Colorado decides to scrap its initial approach, it suggests that the original statutory language may have created unintended consequences or failed to adequately address the specific harms associated with automated decision-making. This legislative pivot forces technology companies, employers, and service providers to discard their existing compliance roadmaps built around SB 24-205. Organizations must now redirect their resources toward understanding and implementing the requirements of SB 26-189. The shift demonstrates that state-level artificial intelligence regulation remains highly fluid, requiring companies to maintain agile compliance programs.

Who Should Care

For lawyers

Corporate counsel and compliance attorneys advising clients on artificial intelligence deployment must immediately update their guidance. Legal teams that previously spent time preparing clients for the requirements of SB 24-205 must now analyze the ADMT Act to identify new obligations, altered definitions, and revised liability standards. Outside counsel will need to draft new policies for clients who develop or use automated systems, ensuring those policies align with the January 1, 2027, effective date. Litigators should also monitor how the shift in statutory language might alter potential causes of action or enforcement mechanisms, as the new text will dictate future regulatory enforcement actions.

For consumers and businesses

Businesses that integrate automated decision-making into their operations face a new set of rules governing how those tools are deployed. For the general public, the ADMT Act alters the legal framework protecting individuals from algorithmic harm. Residents who interact with automated systems—particularly in areas where those systems make consequential decisions—will be governed by the protections outlined in the new bill rather than the discarded AI Act. Companies will need to adjust their consumer-facing disclosures and operational safeguards accordingly.

Legal Background

State legislatures nationwide have struggled to draft durable laws governing artificial intelligence, often finding that statutory language becomes obsolete as software capabilities expand. Colorado initially addressed this challenge by passing SB 24-205, which established the Colorado Artificial Intelligence Act. That earlier law was designed to create a baseline regulatory structure for developers and deployers of algorithmic tools within the state.

However, as the technology evolved and stakeholders analyzed the practical implications of SB 24-205, the original framework apparently proved insufficient or misaligned with the state's regulatory goals. Rather than passing a series of amendments to patch the existing law, lawmakers drafted SB 26-189. The drafting and passage of this new bill reflect a legislative determination that a clean slate was necessary to properly regulate automated decision-making technology in consequential decisions.

What the Legislature Did

Through the passage of SB 26-189, the Colorado legislature executed a complete statutory replacement. Lawmakers formally repealed the Colorado Artificial Intelligence Act established under SB 24-205. In the same legislative stroke, they enacted the ADMT Act.

Governor Jared Polis formalized this legislative action by signing the bill on May 14, 2026. The legislature structured the bill to provide a transition period, setting the effective date for January 1, 2027. This deliberate delay provides the state government and regulated entities with a window to prepare for the new regulatory environment. By focusing the title of the new law specifically on "Automated Decision-Making Technology in Consequential Decisions," the legislature narrowed the semantic focus from the broad concept of "artificial intelligence" to the specific mechanisms and impacts of automated systems.

How It May Be Applied

The primary question moving forward is how regulatory agencies and courts will interpret the ADMT Act compared to the repealed framework. Because the new law takes effect on January 1, 2027, companies have a specific statutory window to audit their automated systems and ensure compliance.

Regulators will likely spend the intervening months drafting administrative rules or guidance to clarify the ADMT Act's provisions. Legal practitioners will be watching closely to see how the state defines a "consequential decision" in practice and what specific documentation, auditing, or transparency requirements the state will enforce against companies. Furthermore, the transition period raises questions about how businesses should handle automated systems currently in development. Software engineers and product managers must align their development cycles with the January 1, 2027, deadline to ensure that any new artificial intelligence tools deployed in Colorado meet the updated statutory criteria. Until the effective date arrives, organizations must operate in a transitional phase, preparing for the new enforcement regime while winding down their reliance on the repealed framework.

Framework Comparison

Feature	Previous Regime	New Regime
Enabling Legislation	SB 24-205	SB 26-189
Statutory Title	Colorado Artificial Intelligence Act	Colorado Automated Decision-Making Technology in Consequential Decisions Bill (ADMT Act)
Status	Repealed	Signed May 14, 2026
Effective Date	N/A (Replaced)	January 1, 2027

The Bottom Line

Colorado has entirely rewritten its approach to regulating artificial intelligence. By repealing the Colorado Artificial Intelligence Act and enacting the ADMT Act, the state has forced businesses to adopt a new compliance framework for automated systems. Companies have until January 1, 2027, to adjust their operations to meet the requirements of the new law.
