Colorado Trims Back Its AI Law After Two Years of Fighting

Colorado's legislature passed Senate Bill 189 on 12 May, gutting most of the country's first comprehensive AI anti-discrimination law and replacing it with a transparency-only framework that takes effect in January 2027. The vote was 57-6 in the House and 34-1 in the Senate. Governor Jared Polis has said he will sign it, ending a two-year fight that pitted civil-rights advocates against the state's tech industry and, in the closing weeks, the White House.

The original 2024 law, SB 205, would have forced companies using AI in hiring, lending or housing decisions to disclose how those systems worked and to run mandatory bias audits and impact assessments. The new version keeps the consumer notification (you have to be told an AI is making a consequential call about you) and adds a right of appeal, but drops the disclosure and audit requirements that gave the original its teeth.

What survived and what didn't

Senate Majority Leader Robert Rodriguez, who sponsored both versions, was candid about the compromise: "We still have consumer protections. It's not as much as I would have liked." The Colorado Technology Association, which lobbied hard against the original, called the rewrite "a more balanced path forward." A coalition of labour and consumer groups called PART described it as "a good first step" while making clear they intend to keep pushing.

Critics inside the legislature were sharper. Representative Javier Mabrey of Denver, one of the six no-votes in the House, told colleagues that "black boxes are deciding who gets hired, who gets housing" and that an after-the-fact notice does not change that. He has said he will return with stronger language in the next session.

The federal pressure

The rewrite happened against a backdrop the original drafters did not anticipate. A December 2025 executive order from the White House calls for federal preemption of state AI rules and proposes withholding federal funds from states that pass conflicting ones. With roughly two dozen state AI bills now in motion and Connecticut's SB 5 just over the line, the question of how much room states have to set their own rules is no longer hypothetical.

For now, Colorado has chosen the milder version of its own law. Whether that buys cover from federal preemption, or simply delays the next round of arguments to January 2027, is what remains unsettled.
