01 · Market Overview

Sports Betting in the Centennial State

Colorado operates one of the most established, operator-friendly regulated online sports betting markets in the United States. Approved by voters via Proposition DD in November 2019 and launched on May 1, 2020, legal mobile wagering is open to anyone 21 or older physically inside Colorado state lines.

Colorado bettors can wager on in-state college programs such as the Colorado Buffaloes and Colorado State Rams on game lines and totals, while individual college athlete prop bets are prohibited under state regulations.

02 · CDG Regulation

Colorado Division of Gaming Oversight

All online sportsbooks in Colorado are licensed through master casino licenses in Black Hawk, Central City, and Cripple Creek under the supervision of the Colorado Division of Gaming (CDG) and the Colorado Limited Gaming Control Commission, with tax revenue supporting the Colorado Water Plan.

CDG regulation mandates strict financial reserve requirements, certified odds integrity, verified PayPal/ACH/debit payouts, and accessible responsible gaming controls on every licensed mobile app.

03 · Licensed Operators

Top Sportsbooks & Welcome Offers in CO

Colorado’s competitive licensing framework attracted premier national sportsbooks including DraftKings Sportsbook, FanDuel Sportsbook, and Caesars Sportsbook. Because operators compete fiercely across the Front Range, Colorado players enjoy top-tier welcome bonuses, daily odds boosts, and loyalty rewards.

Maintaining accounts with two or three CDG-licensed sportsbooks lets Colorado bettors compare NFL spreads, NBA player props, and NHL puck lines in seconds.

04 · Local Teams

Mile High Pro Franchises & Local Action

Denver is one of the select US cities home to franchises in all four major professional sports leagues. The Denver Broncos (NFL), Denver Nuggets (NBA), Colorado Avalanche (NHL), and Colorado Rockies (MLB) generate heavy year-round betting volume across the state.

Combined with college football Saturdays in Boulder and Fort Collins, plus winter sports and championship golf events, Colorado’s sports betting calendar stays active all 12 months of the year.
