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 in the US 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 Best Bonus Bets guide is just what you need. 

We’re going to look at the history of CO online gambling and examine in more detail its online sportsbooks. In addition, we’ll look at some of the ways you can benefit from the best betting offers, bonuses and promotions in the many online sportsbooks Colorado has to offer.

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. 

Complete List of Legal CO Online Gambling Sites and Apps

While Colorado punters don’t get to enjoy as many gambling opportunities as some other US states, there is a full selection of online sportsbooks to choose from. 

Legal Online Casinos in Colorado

The Centennial State is home to a wide selection of land-based casinos, most of which are in Black Hawk or Cripple Creek. 

Online casinos are prohibited in Colorado, however, residents and visitors who want to play casino games online can do so at sweepstakes casinos such as Luckyland Slots or Chumba Casino. A sweepstakes model is used and this allows them to offer their games. To win on these sites, it’s not necessary to purchase.  

Legal Online Sportsbooks in Colorado

There are 33 retail casinos in the state that are eligible to apply for a sports betting license and so far, more than 20 have been granted. Colorado has the potential to become one of the most crowded online sports betting markets in the US. The table below gives the details of the sportsbooks that have officially launched online operations so far.   

Legal Online Poker Rooms 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.

In the table below, there are some examples of the most interesting markets you can bet on, as well as their average rates in Colorado. 

Online Gambling in Colorado in Comparison With Other States

In Colorado, you can enjoy most forms of gambling at physical locations, but for now, only sports betting, horse racing, and Daily Fantasy sports betting are legal. It has this in common with a number of other states, however, New Jersey and United States also allow online casino gambling and online poker rooms. 

Benefits of Legal CO Online Gambling over In-Person Gambling

While your online gambling CO options aren’t as wide as a few other states, its sports betting market does have many benefits which can’t be denied. 

Let’s compare the two options further in this table:
