Colorado legislature passes revised AI regulation bill watering down original law
Colorado legislature passed a compromise measure watering down the state's first-in-the-nation AI law, with the narrower version moving key requirements to disclosure-only obligations and delaying implementation to January 2027.
Objective Facts
After attempting to amend its first-in-the-nation AI law for two years and three legislative sessions, on May 9, 2026, the Colorado legislature passed SB 26-189. SB 26-189 replaces the original law's broad "high-risk artificial intelligence system" and "algorithmic discrimination" framework with a narrower regime focused on "automated decision-making technology" (ADMT) that processes personal data used to "materially influence" a "consequential decision," and shifts compliance obligations away from broad governance and impact assessments toward targeted consumer disclosures, post-adverse-outcome explanations, correction rights, and meaningful human review. SB 189 passed by a bipartisan 34-1 vote out of the Colorado Senate and bipartisan 57-6 vote out of the House. The bill will next head to Colorado Governor Jared Polis, who is expected to sign it, having been a driving force in the drafting of the bill. The law is expected to be signed into law and will go into effect January 1, 2027.
Left-Leaning Perspective
Robert Lindgren with the Colorado AFL-CIO, representing the left-leaning labor constituency, stated the bill allows "corporations with more wealth than most nations on Earth" to evade meaningful accountability. Left-leaning critics argue the bill doesn't go far enough because it eliminates the requirement for developers to disclose how AI systems are created and trained, removes risk management requirements, impact assessments and annual reviews, and lacks testing requirements. State Rep. Javier Mabrey, a Denver Democrat, highlighted a key concern: that consumers and sometimes the developers and deployers of AI themselves don't know how the technology works. The left's coverage emphasizes what was lost—comprehensive risk assessment and transparency requirements—and views the bill as capitulation to tech industry lobbying pressure. According to reporting, Senate Majority Leader Robert Rodriguez acknowledged that "the massive amounts of money and investment that would be put on this" by the tech industry, noting lawmakers "could have probably built a wing here at the Capitol, build us our own ballroom with the amount of money that's been spent on this topic," language that echoes progressive frustration with corporate influence. However, Kjersten Forseth, legislative director for AFL-CIO and a spokesperson for PART (People's Alliance for Responsible Technology), acknowledged the bill is "a good first step to protect the interests of everyday Coloradans from some of the negative consequences of AI" while noting "there's still work to be done to ensure Big Tech companies are transparent and accountable." This suggests left-leaning groups adopted a pragmatic stance accepting incremental progress while reserving criticism.
Right-Leaning Perspective
Brittany Morris Saunders, president and CEO of the Colorado Technology Association—a trade group central to the negotiations—said SB 189 "represents meaningful progress for Colorado and a more balanced path forward," and the CTA "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." Business leaders expressed relief that the new bill corrected existing issues, noting the out-of-state move of software giant Palantir and other companies' hesitation to grow in Colorado due to the original 2024 AI law. Loren Furman, CEO of the Colorado Chamber of Commerce and member of the AI policy working group, told lawmakers that "creating this balancing act was really important" because "this bill is probably going to be used as a model in other states," and it took the working group six months and 11 drafts to settle on the proposal. Bryan Leach, CEO of Ibotta, the Denver-based shopping app, said SB 189 "is a marked improvement over the original bill that was passed," feeling it's a much more practical approach even though he was not happy with everything in the measure. The right's framing emphasizes practical workability, economic competitiveness, and stakeholder consensus. However, Meghan Pensyl, director of policy for the Business Software Alliance, had mixed reactions, praising some parts but worrying other modifications could expand the law's scope in unwarranted ways and risk developers being held responsible for deployer actions, calling SB 189 "really a mixed bag." This shows that even tech advocates have concerns about specific provisions.
Deep Dive
Colorado's AI regulation saga began in 2024 when the legislature passed Senate Bill 205, the nation's first comprehensive law governing AI. Almost immediately after Governor 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. Attempts to reach a deal between businesses and consumer advocates during the regular 2025 lawmaking term and a special legislative session in August failed, so the legislature extended the law's effective date from February to June to allow more time for compromise. To break the legislative logjam, a working group of lawmakers, the Governor's office, the Attorney General's office and stakeholders convened in fall 2025. Although the group released a proposal on March 17, 2026, even its members stated it needed further work, but the proposal provided a framework from which the legislature could negotiate a consensus bill. The Colorado reversal is significant because it represents comprehensive AI legislation failing to survive contact with political and business reality. Some Colorado policymakers argued that state-level AI law more stringent than what the federal government or other states require creates a compliance burden that pushes AI development activity out of Colorado—a "race to the bottom" on AI regulation dynamic that SB 189 reflects. Business leaders cited the out-of-state move of software giant Palantir and other companies' hesitation to grow in Colorado as evidence the original law was counterproductive. The shift also reflects pro-innovation sentiments sweeping the U.S.—the original AI Act was passed when global jurisdictions sought firm safety measures, but in the years since, the tone around AI shifted toward allowing technologies to reach their potential and addressing safety only where it won't stifle innovation. Federal pressure compounded the pressure: President Trump threatened to withhold federal funds if Colorado enforced the original law and called it cumbersome in an executive order, and Elon Musk's xAI company filed a lawsuit challenging the law's constitutionality. The bill's passage raises questions about the sustainability of state-level AI regulation. Critics have expressed concerns from multiple directions—some technology advocates argue the rules remain burdensome for AI developers, while some consumer advocates believe the bill weakens protections compared with earlier proposals. Even among business supporters, the Business Software Alliance's Meghan Pensyl offered mixed assessment, praising some parts but worrying other modifications could expand the law's scope unwarrantedly and risk developers being held responsible for deployers' actions, calling SB 189 "really a mixed bag." Key unresolved questions include whether disclosure-only requirements will prove adequate to prevent algorithmic discrimination in employment, lending, housing and other consequential domains, and whether other states will follow Colorado's narrower model or maintain more comprehensive frameworks as the national regulatory landscape evolves.
