Sports Betting in Colorado

Colorado has a thriving sports betting industry with dozens of online sportsbooks and retail sportsbooks at casinos in Black Hawk, Central City, and Cripple Creek. Since launching in 2020, Colorado has become one of the most open markets in the U.S.

DFS and the state lottery are legal. Colorado casinos (land-based) offer slots, table games, and poker, but online casinos remain illegal.

Sports betting covers all professional leagues and college sports, but proposition bets on college players are restricted. Otherwise, bettors 21+ can enjoy single-game, parlay, futures, and live betting on nearly every market.
