Best Gambling Sites in Colorado 2026

175 platforms available across 16 categories in Colorado. Regulated by the Colorado Division of Gaming.

Legal data last verified April 7, 2026

Fact-checked 2026-04-07

Colorado voters narrowly approved Proposition DD in November 2019, authorizing sports wagering tied to the state's 33 commercial casinos. Mobile betting launched on May 1, 2020, just as the pandemic paused live sports, yet the market has grown every year since.

Proposition DD earmarked sports betting tax revenue for the Colorado Water Plan, meaning nearly every dollar the state collects funds water conservation and protection projects. The Colorado Division of Gaming, housed under the Department of Revenue's Specialized Business Group, handles licensing and rulemaking. Each retail casino can partner with one online skin, though most mobile operators enter via master license agreements.
