Colorado Sports Betting 2026
Colorado's voter-approved sports betting market launched in May 2020 with a 10% tax, and it remains one of the most operator-friendly and competitive in the country heading into 2026.
Overview
- Launched: May 1, 2020
- Regulator: Colorado Division of Gaming (Department of Revenue)
- Tax rate: 10% of net sports betting proceeds
- 2025 handle: $6.519 billion
- Active online operators: 14+
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.
Regulatory Backstory
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.
Current Market Landscape
Colorado's handle topped $6.519 billion in 2025, a 5.4% increase over 2024, with statewide revenue of $442.8 million, according to the Colorado Division of Gaming. October 2025 was a standout month with $680.5 million in handle. The state hosts 14+ active online operators, including DraftKings, FanDuel, BetMGM, Bet365, Caesars, and Fanatics.
What Makes This State Different
Colorado's 10% tax rate is among the lowest in the country and has helped attract a crowded operator field. The state also allows promotional deduction (free bets) against the tax base, though starting in July 2025 that deduction is capped at 2.5% of handle and drops a quarter percent annually until it hits 1.75% in July 2026. Colorado is also the rare state where sports betting tax is constitutionally committed to water projects.
How to Sign Up
Bettors must be 21 or older and physically located in Colorado. All registration is remote; no in-person visit is required. Sportsbooks verify identity with full name, date of birth, address, and the last four digits of your SSN, and geolocation software confirms your location for every wager.
2026 Outlook
Expect continued pressure on promotional deductions as the cap steps down to 1.75%. With 14 operators fighting for share, Colorado bettors will continue to see some of the most aggressive promo competition in the US. Water funding advocates and legislators have also floated ideas for raising the 10% rate, but no serious proposal has advanced.
Responsible Gaming Resources
Colorado's official responsible-gaming system directs players to 1-800-GAMBLER and the Division of Gaming's statewide self-exclusion list. That list covers casino gambling plus on-site and online sports wagering for one, three, or five years, can be requested online, by PDF/email/mail, or in person, and bars a person from collecting winnings, points, bonuses, comps, or free play while excluded.
The Bottom Line
Colorado's low tax rate, deep operator roster, and water-conservation funding story make it one of the most distinctive and bettor-friendly US sports betting markets. Expect price competition and promo offers to remain strong through 2026.
