Online Gambling CO – Complete Guide for Legal Apps and Sites in Colorado

Horse racing has been popular in Colorado since the 19th century, although there is only one racetrack left, Arapahoe Park in Aurora, that’s been open and operating for more than two decades. Up until 2020, this was the only sports betting that was allowed. However, in May 2020, the governor signed the necessary bill and online sports betting went live and Colorado finally joined the online gambling USA scene. 


Aside from sports betting, Colorado online gambling fans can also enjoy fully legalized daily fantasy sports play and horse betting. At present, online lottery play, online casino games, and online poker rooms are not legal. If you want to know more about your Colorado online gambling options, this How To Bet guide is just what you need.

Is Online Gambling Legal in Colorado?

See the answer of the question ‘is online gambling legal in Colorado’

A series of events led to the legalization of Colorado online gambling. Casino gambling had been legal in the Centennial State for many years but it wasn’t until 2018 that sports betting looked like it was going to be a reality. 

It was in 2018 that the Supreme Court made its historic ruling that allowed states to create their own sports gambling laws. One more obstacle was removed in the same year when state Attorney General Cynthia Coffman said that the state couple pass new sports gaming laws without having to change the constitution. This made it much easier for lawmakers and things got underway.

In early 2019, lawmakers passed proposition DD. in May, the governor signed it and in November voters approved it. On May 1, 2020, online sports betting went live in Colorado. Colorado House Majority Leader Alec Garnett placed the first ceremonial legal bet in the state. He bet $10 through the DraftKings mobile app on the Denver Broncos (+4000) to win the Super Bowl.   

Colorado Online Gambling Revenue

Compared to many other states, Colorado doesn’t offer up the same breadth of stats, for example, it doesn’t divulge how each operator is performing. Nor do the state revenue reports denote what bets were placed online and which were placed at brick-and-mortar sportsbooks. Nonetheless, there are some pretty impressive numbers that they provide.

Colorado online sports betting has rocketed over the fall season thanks to an abundance of football and basketball activity. For the last four months of 2021, total sports betting handle was steady between $400 and $500 million. While it never topped the magical $500, the highest month of the year was in October with over $491.4 million wagers taken. 

For the whole of 2021, nearly $3.85 billion in wagers were accepted by Colorado sportsbooks online and at retail locations. Mobile sports betting accounted for over 98% of total wagering throughout the same year.

Legal Online Casinos in Colorado

Poker fans can enjoy a game at one of four land-based poker rooms in Colorado Springs, Denver & Black Hawk, and Greater Colorado.

Online poker in Colorado is prohibited and there aren’t any legal options in the state, apart from sweepstakes sites such as Global Poker. It’s unlikely that this will change anytime soon as state legislators seem very hesitant to move online gaming expansions forward.
