All Betting Sites Available in Colorado

Here’s a full list of sports betting sites currently available in Colorado in alphabetical order: 

Best Colorado Betting Sites Bonuses and Promotions

There are no legal restrictions in terms of the size and type of bonuses CO betting sites can offer players, which gives them considerable wiggle room and a chance to be creative. The only restriction applies to advertising purposes and bonuses deemed free bet bonuses. Namely, if you see a free bet bonus on the site or our page, the bonus is truly free, so you need not stake real money to get the bonus. 

21+ only, must be present in Colorado, terms and conditions apply. If you or someone you know has a gambling problem, call 1-800-522-4700 where trained counselors can refer you to treatment options in Colorado.

Type of Bonuses and Promotions Available in Colorado

Colorado sportsbooks rely heavily on bonuses to appeal to new players and retain the existing account holders. The competition is fierce, so the quality of prizes can be the only thing to get bettors to decide on one sportsbook over the other. 

Below are some of the most common types of bonuses and portions in Colorado sports betting apps:

  • Deposit match bonus: CO sportsbooks may match a portion of your first deposit in bonus funds. The bonus funds are either issued as site credit or a bonus bet. You can spread site credit on multiple events and markets, whereas with a bonus bet, you might be required to use the entire sum on a single event. 
  • First bet bonus: First bet bonuses are usually part of sign up promotions. When you deposit and place a first bet on the site, the sportsbook will match your initial stake in site credit or bonus bet. If you are successful in betting with the bonus, you can cash out only the winnings generated from the wager, not the bonus stake. 
  • Odds boost: While odds boost may not be considered a separate promotion, they can make all the difference in the world for bettors. Colorado betting sites may boost the odds for specific events between 10 and 25% on average, thus willingly reducing their juice and giving players a chance to win more if the bets are settled in their favor. 
  • Cashback bonus: Cashback bonuses are particularly useful when it comes to easing the pain from a loss, especially if you lose that final leg of the parlay. A sportsbook will give you back a percentage of your losses accrued over a designated period back as bonus bets. Usually, you will get up to 10% back. 
  • VIP/Loyalty program: Most sportsbooks have a dedicated promo campaign directed towards regular depositors and players to reward them for their loyalty. These VIP/loyalty programs, such as Caesars Rewards or BetMGM’s MGM Rewards, give players tier and rewards credits every time they place a wager. Reward credits can be exchanged for free bets, bonus bets, and other perks, while tier credits contribute towards higher levels of the program and more generous rewards. 
  • Free bets: Free bets are the rarest forms of bonuses found on Colorado sports betting sites and the most coveted ones. Namely, CO betting apps will give players a certain amount in bonus bets absolutely for free. No deposit or payment is needed. 
  • Matched bet: When bettors place a bet with qualifying odds averaging -120 or longer on a select market or event, the bookies will match a percentage of that stake in bonus bets.  
  • Insurance Bets: Insurance bets provide a safety net should your parlays or other wagers go wrong. Sportsbooks will issue bonus bets in case your moneyline bet falls through in the overtime or your 4+ leg parlay loses. 
  • Refer a friend:  If you spread the good word about a Colorado betting app among friends, a refer them to that book, both you and the friend that registers, verifies, and deposits into the sportsbook will receive additional bonus bets. 

Type of Bets Available in Colorado

Colorado online sportsbooks offer a plethora of betting markets with no restrictions on how much you can stake, unlike their retail counterparts, which can only take $100 bets max. This allows sportsbooks to offer huge payouts, such as Ceasars with its $25 million max payout. 

Here’s a quick list of the most popular wagers in the state:

  • Moneyline: Moneyline bets are the simplest forms of bets where you bet on the match winner. 
  • Point spreads: With point spreads, you bet on the match’s winner and the point margin. The favorite must cover the point spread in its win, whereas the underdog will have to win or lose by fewer points than the indicated spread for the bet to be successful. Point spread in baseball is called a run line. 
  • Totals: Totals are wagers where you choose whether the number of points in a match will be over or under the benchmark number set by the sportsbook. 
  • Props: Props or proposition wagers are bets on the specific outcome of a play in a game, such as will Nikola Jokic score the next basket or will the Broncos score the next touchdown. There can be both team and player props. 
  • Futures: Futures are long-term bets on an event that will happen down the road, such as the Super Bowl or the Stanley Cup. 
  • Parlays: Parlays are wagers where you include several selections on a betslip, and each of these selections needs to come through for the parlay to pay. 
  • Same Game Parlays: With Same Game Parlays, you can include several betting markets from a single event, such as the team’s win, the total number of points, and the number of points from the leading scorer. Most sportsbooks allow you to put between 6 and 10 markets for an SGS. 
  • Teasers: Teasers allow you to shift the game lines a bit to your advantage for better odds but smaller payouts. 

Popular Sports and League to Bet on in Colorado

Colorado hosts a significant number of college and professional teams, which draws a lot of attention from the bettors. State-regulated sportsbooks boast excellent coverage of sports and leagues from across the globe, with a particular emphasis on the Big Four and national college championships. 

  • NFL: The Denver Broncos secured their last Super Bowl championship back in 2016, but with Peyton Manning’s retirement came a bit of a dry spell. However, with new additions to the roster, such as the WR Nick Williams and others, the team looks to improve their 5-12 record in the 2022 season. 
  • NBA: The Denver Nuggets are firing up on all cylinders. Behind a killer duo of Jokic and Murray, the franchise reached its first-ever NBA Finals. In fact, according to the Colorado Division of Gaming’s report, basketball accounted for 24.7% of all bets placed on sports between May 2020 and April 2023. 
  • MLB: Colorado Rockies have been struggling a bit lately but are still generating a lot of betting handle for CO sportsbooks. Last year, the team signed a 3-year partnership deal with bet365 to boost the sportsbook’s visibility in the market. 
  • NHL: Hockey is a beloved sport in Colorado, and the Avalanche always gives the fans something to look forward to. The 2022 NHL Champions are looking solid and are considered contenders every season. 
  • College sports: College sports betting in Colorado is hugely popular, despite the ban on player props. NCAA Basketball and NCAA Football account for the most college wagers.

  • Reliable payment methods: The banking methods in Colorado betting sites include PayPal, Visa, Mastercard, Discover, ACH, PayNearMe, online banking, and even cash at casino options for facilitating fast deposits and withdrawals.

Sports Betting Law and Regulations in Colorado

Colorado has a long history of gambling, led by casinos in the towns of Black Hawk, Central City, and Cripple Creek. Following the fall of the Professional and Amateur Sports Protection Act (PASPA), legislators started working on the legalization of sports betting in the state.

Colorado Sports Betting History

Colorado lawmakers championed the HB19-1327 law in 2019, which passed through the state’s legislation. As per Colorado’s TABOR (Taxpayer’s Bill of Rights) laws, a vote on a general election was required before sports betting could become legal.

Proposition DD was found on the November 2019 ballot and received the backing of over 1 million votes. It’s worth noting that the difference between the “Yes” and “No” votes was less than 50,000. Colorado Governor Jared Polis signed HB 1327 into law, and the first sportsbooks launched in 2020.

Current Situation in Colorado for Sports Betting

As per the sports betting law, each of the 33 casinos in the state can apply for a license to operate an online sportsbook. Currently, there are 24 betting apps with an operating permit from the Department of Revenue, Division of Gaming.

The Next Step for Sports Betting Regulation in Colorado

In 2023, the Colorado Division of Gaming rejected requests for the approval of NHL Draft Lottery Winner, Coin Toss Winner to Defer or Receive, and similar types of wagers. In the past, the governing body rejected appeals for the legalization of betting on entertainment. 

Responsible Gambling in Colorado

Colorado sports betting operators are obligated to offer deposit, spend, session, and other types of limits to help players keep their betting in check. Time-outs and self-exclusion programs are also mandatory responsible gambling tools, as well as partnerships with independent, helpful organizations such as the National Council on Problem Gambling, all in order to help players bet responsibly. 

Colorado Sports Betting Tax Rate

Sports betting operators must pay a 10% tax on net sports betting proceeds. Players are also required to pay income tax on gambling winnings.
