Colorado Comprehensive AI Law Takes Effect June 30 — First US State High-Risk AI Statute

Cooley LLP·medium signal

Colorado's comprehensive AI legislation — one of the most substantive state-level AI governance statutes in the US — takes effect June 30, 2026. The law imposes disclosure and governance requirements on high-risk AI systems, modeled on EU AI Act concepts. This is occurring amid active federal-vs-state tension, with the Trump administration's March 2026 National AI Policy Framework explicitly calling on Congress to preempt state AI laws it deems innovation-limiting. Developers deploying AI systems in Colorado have 28 days to ensure compliance.
