Colorado voters clear revised AI regulation law amid court battles
Colorado legislature passed SB 189, which repeals and replaces the Colorado AI Act, narrowing AI regulations to focus on consumer notice rather than risk assessment.
Objective Facts
On May 12, the Colorado legislature passed SB 189, which repeals and replaces the Colorado AI Act. The House voted 57 to 6 on May 9, 2026, sending the bill to Governor Jared Polis with strong bipartisan support. The legislature passed a compromise measure watering down the state's first-in-the-nation law, replacing a requirement that companies disclose how their AI systems help make decisions on hiring, loans and housing with a requirement to just notify consumers when the technology is being used. It represents the most detailed statutory framework for automated decision-making technology regulation adopted by any U.S. state legislature so far in 2026, arriving at a moment when federal courts are simultaneously reviewing the constitutional limits of state-level AI regulation. Passing the legislation did not eliminate the legal uncertainty surrounding it: on April 27, 2026, a U.S. District Court ordered the Colorado Attorney General not to initiate enforcement of SB 24-205 or any legislation amending it until the Attorney General completes rulemaking and the court issues a ruling in the case X. AI LLC v. Weiser.
Left-Leaning Perspective
The People's Alliance for Responsible Technology (PART), a coalition of labor and consumer groups, expressed guarded support for SB 189. PART legislative director Kjersten Forseth of the AFL-CIO called the bill "a good first step to protect the interests of everyday Coloradans from some of the negative consequences of AI," but added "there's still work to be done to ensure Big Tech companies are transparent and accountable" and expressed encouragement that "there's now a path to hold developers accountable when their technologies result in discrimination and other harm". Dennis Dougherty of the Colorado AFL-CIO, speaking for PART, expressed that the coalition was "cautiously optimistic" about the working group compromise, saying "it provides a path to hold developers and businesses using AI accountable when the technology makes consequential decisions for everyday Coloradans". However, some progressive legislators voiced concerns about specific gaps. State Rep. Javier Mabrey, a Denver Democrat who voted for the bill, said it's a problem that consumers—and sometimes developers and deployers themselves—don't know how the technology works. The left's framing highlighted this as a weakening of consumer protections compared to the original 2024 law, which required explainability and risk assessments. The left's coverage emphasized that while the bill maintains some consumer protections and provides accountability mechanisms, the most significant change is the elimination of the requirement that companies explain how their AI systems work, eliminating the framework requiring companies to provide consumers with specific explanations of decision logic.
Right-Leaning Perspective
Business and technology leaders celebrated SB 189 as a critical correction to what they viewed as an overly burdensome regulatory regime. Brittany Morris Saunders, president and CEO of the Colorado Technology Association, a trade group central to the negotiations on Colorado's AI policy, said the bill "represents meaningful progress for Colorado and a more balanced path forward," noting the group "has worked with policymakers, member companies, and partners across the business and technology communities to advance a framework that protects consumers while allowing Colorado companies to innovate, hire and grow". Bryan Leach, CEO of the Denver-based shopping app Ibotta, said the bill "is a marked improvement over the original bill that was passed" and feels it's "a much more practical approach". Business representatives framed SB 189 as essential to keeping Colorado competitive. Business leaders, citing the out-of-state move of software giant Palantir because of the 2024 AI law and other companies expressing hesitation to grow in Colorado, said the new bill corrects the biggest existing issues. Colorado Chamber of Commerce President/CEO Loren Furman said the bill strikes the balance "that addresses the interests of businesses and consumers and keeps Colorado a place where companies want to do business". The right's framing emphasized that comprehensive risk assessment and explainability requirements would "stifle innovation," making the narrower notification-based approach more workable. Business groups viewed the bill's focus on transparency and notice rather than pre-deployment risk management as pragmatic and protective of both consumer and business interests.
Deep Dive
Colorado's passage of SB 189 marks a significant retreat from comprehensive AI regulation, driven by a collision between AI industry concerns about competitiveness and consumer advocates' desire for strong protections. Colorado's AI regulation saga began in 2024 when the legislature passed Senate Bill 205, the nation's first comprehensive law governing the technology. Almost immediately after Polis signed it into law, he, Rodriguez and Attorney General Phil Weiser signed a letter vowing to revisit and change the policy, citing concerns from the tech industry. The departure of Palantir Technologies, with a market capitalization of $328 billion, from Denver to Miami in February underlined concerns that regulatory issues, including the 2024 artificial intelligence law, had motivated the move. This business exit became a powerful argument for weakening the law. The bill represents what observers have called a "race to the bottom" in state AI regulation. Some Colorado policymakers argued that a state-level AI law imposing obligations more stringent than federal or other state requirements creates compliance burdens that push AI development out of Colorado, a "race to the bottom" dynamic that SB 189 reflects. The compromise framework emerged from private working group negotiations rather than public legislative debate, which occurred after Polis, frustrated by unhealed divisions in public task force debate, called together a second working group that met in private and produced a working document in March signed off by unions, consumer groups, and business associations. This procedural shift insulated the negotiations from public scrutiny. Looking ahead, significant uncertainty remains. A U.S. District Court issued an order on April 27, 2026, ordering the Colorado Attorney General not to initiate enforcement until the Attorney General completes rulemaking and the court issues a ruling in X. AI LLC v. Weiser, a case in which the DOJ has intervened. Even if Polis signs SB 189, xAI's lawsuit may challenge the new law under constitutional grounds. SB 189 is structured as a repeal and replacement rather than a simple amendment, but whether that distinction is sufficient to place the new bill outside the scope of the court's April 27 order is a question Colorado's Attorney General and courts will need to resolve.
