Who can bet on sports in Colorado?

Anyone 21-years of age and over and located in the state may place a sports bet in Colorado. Players can visit a physical sportsbook or use a computer or mobile device to wager online.

Here’s everything you need to know before placing your first sports bet in Colorado.

The pros and cons of Colorado sports betting

Fully remote registration is a massive win for Colorado sports bettors. With nearly all of the state’s casinos situated in three sparsely populated rural areas, accessibility could have been a significant hurdle otherwise.

There’s not much to gripe about when comparing Colorado sports betting laws to those of other states. The absence of college prop bets is the only real significant betting opportunity omitted from Colorado law.

Low barrier to entry for online operators

Fully online registrations and deposits

No limit on the size of bets

No college prop bets

Glitchy geolocation software

Retail outlets in remote areas

How to start betting in Colorado

With remote registration and online betting, it’s easy to get started with sports wagering in the Centennial State. Alternatively, Coloradans may visit a brick-and-mortar sportsbook in a state-licensed casino if physical bets are preferred.

What you can't bet on in Colorado

Colorado may have the least restrictive sports betting law in the country. Flush with betting opportunities, Coloradans and visitors of the Centennial State can lay a sports bet on just about any event imaginable.

However, there are a few exceptions highlighted here:

NFL Draft

Colorado sports betting does not include wagers on political events.

Awards ceremonies

While popular with offshore sites, celebrity and pop-culture events such as the Academy Awards are off-limits at Colorado sports betting sites

Colorado sports betting handle

Colorado has quickly become a significant market for sports betting in the United States. The state has registered over $3 billion in sports bets in the year following the legalization of sports wagering.
