The state launched its regulated services in May of 2020, with mobile services debuting shortly after.

Can you bet on sports at age 18 in Colorado?

In Colorado, state-licensed sports betting was legalized in CO and was rolled out in 2020, including approval for mobile options as well. Brick-and-mortar sportsbooks have been launched at select locations throughout Colorado’s historic mining districts and other authorized state casinos, and bettors in CO can place wagers on athletics via mobile apps, tablets, laptops, or PCs.

The minimum age required to gamble at a casino is 21 years old, but eighteen-year-olds in CO are able to wager at the betting sites we recommend. In this particular scenario, we advise following the age requirements at casinos when placing a bet online for sports, even though no one has ever been arrested, charged, or prosecuted for sports betting in Colorado.

Is it legal to bet at 18+ online sportsbooks in Colorado?

There is no law preventing Colorado residents who are at least 18 from signing up and betting at any of the licensed offshore sports betting sites we recommend. However, as stated above, the land-based casino gambling age in the state is 21, and we recommend following that required age for anyone betting in Colorado. State-regulated mobile sportsbooks will only accept bets from patrons over the age of 21.

Are sports betting sites safe for Colorado residents?

Yes, but we can only guarantee the safety and security of the online sportsbooks on our site since we’ve vetted each one and can safely recommend them to all Colorado residents at least 18 years of age.

How did PASPA’s repeal affect legal sports betting in Colorado?

The Professional and Amateur Sports Protection Act of 1992 had previously prevented Colorado lawmakers from crafting legislation to legalize state-licensed sports betting within its jurisdiction. That changed with the Supreme Court repeal of PASPA in May 2018, allowing lawmakers from each state the ability to legalize land-based and online sportsbooks within state lines. Almost two years later, voters passed domestic sports betting legislation at the polls.

Colorado Sports Betting Laws/Pending Bills

Proposition DD was passed by a voter referendum in 2019. This allowed state lawmakers to pass HB-19-1327, which authorizes domestic sports betting throughout the state. The bill restricts domestic sportsbooks to state casinos but also allows mobile betting. Domestic Colorado sportsbooks have now been issued licenses and have been in operation since May 2020.
