Colorado 18 and Up Sports Betting Sites

Colorado flag and outlineDespite how open Colorado is to pretty much every form of gambling, the state has consistently given domestic sports betting the cold shoulder time and time again, until it was left up to the voters to decide. In November of 2019, CO voters passed Proposition DD to allow physical and mobile sportsbooks to operate within state lines. The state launched its regulated services in May of 2020. Mobile services followed shortly after the sportsbooks start accepting bets.

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 as well.

The minimum age required to gamble at a casino is 21 years old, but eighteen years 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.

There is no law preventing Colorado residents who are at least 18 years of age 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 years old 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.

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 who are 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.

The bill restricts domestic sportsbooks to the state casinos but also allows mobile betting. Domestic Colorado sportsbooks have now been issued licenses and have been in operation since May of 2020.
