No public action found
Colorado regulators are monitoring prediction-market litigation but have taken no enforcement action; the attorney general has urged federal limits.
No Colorado cease-and-desist letter, lawsuit, or prediction-market bill was found. The Division of Gaming told reporters in May 2026 that it is monitoring the court cases involving Kalshi and declined further comment. Attorney General Phil Weiser joined a 41-attorney-general comment letter asking the CFTC to recognize state authority over sports event contracts, and Colorado joined a 37-state Sixth Circuit amicus brief.
