CO Horse Betting Rules

Colorado horse betting is legal. The state has had legal horse betting for quite some time since pari-mutuel betting was legalized in the 1950s. Betting on races online is a relatively new phenomenon in Colorado, but the industry is growing.

Betting on horse racing is legal with the one provision that websites must be licensed to offer Advance Deposit Wagering. Websites that are legal in Colorado will clearly state that fact on their account sign up page.

According to the Colorado Department of Revenue, only a certain number of betting sites are authorized to allow ADW or any kind of online wagering in the state. Please refer to the Dept. of Revenue’s page on ADW found here.

CO Horse Racing Tracks

There is only one live venue to enjoy Colorado horse betting, and that’s at Arapahoe Park in Aurora. There are about a dozen locations for Coloradans to enjoy off-track betting, and that doesn’t include their options for online horse betting.

Coloradans looking for races other than thoroughbred and quarter horses will not have many options. Greyhound racing was banned in Colorado in 2014, but it is possible to bet on legal greyhound races across the country using horse betting apps like TVG and TwinSpires.

More and more services are being added to the list of available operators. Colorado laws are changing regarding betting on live events, so it’s entirely possible that horse betting options will expand in the near future.
