Colorado AI Law Takes Effect June 30, Further Fragmenting U.S. Regulation
Colorado legislature passed SB 189 on May 12, replacing its comprehensive AI law with a narrower disclosure-based framework, expected to be signed by Governor Polis.
Objective Facts
On May 12, 2026, the Colorado legislature passed SB 189, which repeals and replaces the Colorado AI Act by a vote of 34-1 in the Senate and 57-6 in the House. The decision followed a federal magistrate judge's stay of the original law on April 27, 2026, and the U.S. Department of Justice's intervention on April 24 to join xAI's constitutional challenge. The replacement represents a major scaling-back, eliminating the original law's risk management programs, annual impact assessments, and extensive algorithmic discrimination duties in favor of a narrower notice-and-transparency framework. Although the bill removes many obligations, Colorado still will have the most far-reaching legislatively enacted deployer/private sector AI law of any state, yet the bill's passage only adds to an increasingly complex state regulatory regime for businesses to navigate, including California's risk assessment regulations and soon-to-be Connecticut employment laws. A spokesperson for Governor Polis issued a public statement indicating SB 189 has achieved the governor's goals and that he will sign the bill.
Left-Leaning Perspective
Robert Lindgren with the Colorado AFL-CIO criticized the revised law, stating that "Gone are the risk management requirements, impact assessments, annual reviews and discrimination reporting," and characterized the framework as stripping away important worker and consumer protections. Kjersten Forseth, legislative director for AFL-CIO and spokesperson for PART (People's Alliance for Responsible Technology), called the bill "a good first step" while acknowledging that "there's still work to be done to ensure Big Tech companies are transparent and accountable," noting the law enables holding developers accountable only when technologies result in discrimination. Democratic Representative Brianna Titone, who sponsored the landmark 2024 bill, indicated that workers and consumer rights groups faced an obstacle because Governor Polis did not want to sign a bill without the tech industry on board. The Colorado AFL-CIO believes that the lack of discriminatory analyses and comprehensive program explanations in the new bill rolls back needed protections for consumers and workers. Representative Javier Mabrey, a Denver Democrat who voted for the bill, expressed concern that consumers and sometimes developers and deployers of AI themselves don't know how the technology works. Left-leaning coverage emphasized that the law's removal of explainability requirements and impact assessments represented a significant weakening of consumer protections, particularly compared to the EU AI Act model the original law was based on. Left-leaning outlets and advocates downplayed or did not emphasize the bipartisan consensus achieved in SB 189, focusing instead on the specific protections lost rather than provisions that remained (like consumer notice and appeal rights). They also underreported industry claims that the original law was unworkable, instead framing SB 189 as a political capitulation to tech industry pressure rather than a necessary compromise.
Right-Leaning Perspective
Brittany Morris Saunders, president and CEO of the Colorado Technology Association, said SB 189 "represents meaningful progress for Colorado and a more balanced path forward" creating "a framework that protects consumers while allowing Colorado companies to innovate, hire and grow." Business leaders pointed out that software giant Palantir moved out of state because of the 2024 AI law and other companies expressed hesitation to grow in Colorado because of it, saying the new bill corrects these issues. The Business Software Alliance stated that "the broad definitions and new liability regime proposed by SB26-189 make AI innovation and adoption more difficult in Colorado, contrary to state leaders' goals," arguing the law would "disrupt existing contracts between developers and deployers, and introduce a new, untested, and unworkable liability scheme that holds AI developers responsible for consequential decisions outside of their control." The tech industry consistently argued the original law was "unworkable and would stifle innovation," with President Donald Trump threatening to withhold federal funds if Colorado enforced it and calling it cumbersome in his executive order barring states from passing robust AI regulations. Right-leaning outlets and business advocates emphasized innovation and economic competitiveness concerns, characterizing the narrower SB 189 as a necessary correction to retain business investment. They downplayed or did not focus on consumer protection gaps created by removal of explainability requirements and impact assessments, instead framing the law as a reasonable transparency approach.
Deep Dive
Colorado became the first state in 2024 to enact comprehensive AI law (SB 24-205), which regulated developers and deployers of "high-risk" AI systems requiring them to use reasonable care to protect consumers from algorithmic discrimination and imposed a proactive compliance regime including documentation, disclosures, and impact assessments. Almost immediately after passage, the law drew sharp criticism from the business community, prompting the legislature to delay its effective date and Governor Polis to convene a policy workgroup, with the White House specifically referencing the law as "burdensome" in an executive order. In April 2026, the U.S. Department of Justice moved to intervene in xAI's lawsuit against the law—marking the first time the DOJ sought to intervene in a lawsuit challenging a state AI law—with xAI arguing that Colorado's law unconstitutionally forces private AI developers to embed the state's preferred ideological views into its products. A federal magistrate judge stayed enforcement on April 27, 2026, and the Colorado Attorney General joined the plaintiffs in filing a joint motion stipulating to a temporary stay, creating an opening for legislative revision. Governor Polis convened a workgroup that released a proposed framework in March 2026, which was introduced as SB 189 on May 1 by lawmakers led by Colorado Senate Majority Leader Robert Rodriguez (the original law's sponsor). SB 189 adds to the growing complexity of state AI regulation because, while it removes many Colorado AI Act obligations in favor of a more business-friendly regulatory regime, the bill joins a far more complex state regulatory landscape than existed when the original Colorado AI Act became law. Since 2024, California, Illinois, Texas, Connecticut and a dozen other states have passed AI-related laws, and SB 189 only adds to this state-by-state patchwork. The Colorado reversal is significant as the most prominent example of comprehensive AI legislation failing to survive contact with political and business reality. What to watch: xAI will file its motion for a preliminary injunction within 28 days after the state finalizes rulemaking for SB 189, and the court said xAI and the DOJ should file new motions within 28 days after lawmakers pass amended legislation. The DOJ's continued involvement signals the federal government intends to challenge state AI laws broadly, not just Colorado's.
