Colorado’s position
Legal sports betting began in Colorado on May 1, 2020, after voters approved it in 2019, and it’s regulated by the Division of Gaming. Bettors must be 21.
Attorney General Phil Weiser joined other attorneys general in an April 2026 comment urging the CFTC to recognise state authority over sports-related prediction markets, and signed the October 2026 states’ brief at the US Supreme Court. Speaking to KUNC in May 2026, Weiser said of Kalshi: “You’re undermining the will of Colorado voters.” The Division of Gaming said it is “monitoring the various cases making their way through the courts.” KUNC also reported that a 2026 sports betting reform bill (SB26-131) would not apply to Kalshi.
