Colorado has one of the nation’s largest sports betting industries, with 13 online operators and 12 retail facilities. Here, we’ll explore the Colorado sports betting landscape and offer guidance for beginners.
Colorado launched its sports betting industry in May 2020 in the midst of the COVID-19 pandemic, but the industry has flourished since then. As of March 2025, Colorado ranks sixth in lifetime sports betting handle (more than $22.6B wagered) among the 38 states that have legalized the practice.
With 13 online sportsbooks in Colorado, along with 12 brick-and-mortar betting facilities, the state’s gambling landscape can be a bit tricky to navigate. Fortunately, Bettor in Green is here to clear things up!
With this guide to Colorado sports betting, we’ll discuss the top sportsbooks in the state and review the history of sports gambling in CO. We’ll also provide tips for new bettors and highlight responsible gambling resources.
Below are our picks for the Top 5 best sportsbooks in Colorado. These bookmakers were selected for their bonus frequency and generosity, mobile app performance, customer service quality, ease of money management, and much more.
DraftKings had already begun growing its brand in Colorado well before sports betting was legalized as the company started by running daily fantasy sports (DFS) contests. It has since become one of the most popular sportsbooks in the country and is a dominant force in the Colorado market; it is the only entry in our Top 5 with a retail option in the state.
One of the biggest strengths DraftKings Sportsbook CO has to offer is its in-play betting array, with live odds of many matchups that are in progress. DK is also quite generous in offering bonus bets and odds boosts, which you can access on a daily basis with email and push notifications turned on.
Bettor In Green’s Opinion: DraftKings is a very well-rounded sportsbook that provides a solid platform for gamblers of all bankrolls and experience levels.
bet365 Sportsbook Colorado is a reliable choice for odds and line shopping, especially for international soccer betting enthusiasts. It also boasts impressive depth in niche sports markets, which makes for a respectable counter to mainstream sports and leagues.
In our experience, bet365 frequently provides promos with the lowest minimum qualifying wagers for welcome bonuses among Colorado sportsbooks. Wagers with a stake as low as $1 can lead to hundreds in platform credits; additionally, users are occasionally able to choose a welcome offer that aligns well with their gambling objectives.
Bettor In Green’s Opinion: bet365 offers top-notch customer support, and outside of a few minor areas, we don’t have a ton to criticize. However, we would like to see additional deposit and withdrawal options added to the bookie’s methods list.
Fanatics Sportsbook CO acquired PointsBet’s U.S. gambling licenses in the summer of 2023 and has been a surprisingly good addition to the industry. Despite not having a background in a gambling space (Fanatics is a titan in the world of sports merchandising and memorabilia), the bookie has delivered with an impressive mobile app.
Gamblers on Fanatics receive “FanCash” for every bet they place which can then be used to acquire betting bonuses. However, it can also be redeemed while making purchases at any Fanatics-affiliated e-tail site.
Bettor In Green’s Opinion: Fanatics’ merchandising vertical provides strong financial backing, allowing the gambling platform to develop and thrive while raising the bar for both businesses. Expansion to a web browser platform will be the next major step, and unlike other bookies, Fanatics does not need to pursue retail development.
Since it launched at the Rivers Casino in Pittsburgh in March 2020, BetRivers has provided sports gamblers with a rewarding betting experience through its web platform and mobile app. It was one of the first sportsbooks to launch in Colorado, and its app is one of the highest-rated in the industry.
The website and mobile platforms saw major upgrades in 2024 as BetRivers unveiled a more modern aesthetic while addressing issues with slow load times; both platforms are noticeably better. Furthermore, the iRush rewards program continues to benefit loyal BetRivers users.
Bettor In Green’s Opinion: We found BetRivers to be a go-to option for odds shopping in niche sports, and it offers a good change of pace in mainstream leagues as well. The iRush Rewards program is essential for regular users.
Another worthy addition to our Top 5 is FanDuel Sportsbook CO, which, like DraftKings, was already a major DFS operator in Colorado before bringing its sports betting platform to the Centennial State. It has the highest-rated mobile app of any Colorado operator, with an intuitive, easy-to-use interface that is great for beginners.
FanDuel facilitates some of the fastest payout times among Colorado sports betting sites; on several occasions, we were able to get money into our bank accounts within a few hours of submitting a withdrawal request. While this does depend on the size of your withdrawal and the method you’re using, FanDuel can accommodate in most cases.
Bettor In Green’s Opinion: FanDuel is sure to please Colorado gamblers, especially same game parlay enthusiasts. The bookie’s SGP availability is second to none.
In addition to our top sportsbooks list above, these other sportsbooks in Colorado can get the job done, though they may not be as beneficial or enjoyable overall.
Bally Bet fell short of a place in our Top 5 because it has a smaller array of available markets than nearly every other retail and online bookie in Colorado. In our testing, it also had the longest withdrawal times by a wide margin.
BetMGM Sportsbook Colorado is our favorite sportsbook for futures betting, as the bookie is often the earliest to post lines and odds for long-term wagers. We’re also fans of BetMGM’s rewards program that offers a range of betting perks and non-gambling-related benefits
Operating solely on mobile apps for Apple and Android devices, BetMonarch has a smaller list of available sports than most other Colorado operators, but we found that odds tended to be slightly more bettor-friendly than the big-name competitors. It lists that promos are “coming soon” in the app, but BetMonarch has yet to hint at a release date.
Caesars Sportsbook Colorado has the largest retail presence, accounting for four of the state’s 12 brick-and-mortar sportsbook options. For online and mobile bettors, Caesars has a tendency to offer lucrative welcome bonuses that can exceed $1,000 in platform credits.
Another smaller operation, Circa Sports is known for having “high limit” sports betting, accepting stakes that are significantly larger than the amounts that are accepted through other mobile platforms. In lieu of offering a rewards program or betting bonuses, Circa has reduced the “juice” so that however you bet, the odds will be more bettor-friendly than any of our Top 5.
ClutchBet is only available in two other states (Iowa and Louisiana), and its odds listing reflects the smaller geographic reach. However, to offset this, ClutchBet introduced ClutchCash, which allows gamblers to create custom head-to-head props bets for NFL and NBA matchups.
ESPN Bet replaced Barstool Sportsbook as the brand face of PENN Entertainment’s betting platform. It offers loads of content from ESPN’s on-air talents, and users can cash in with the PENN Play Rewards Program.
Finally, SBK Sportsbook comes with a Price+ tool to allow you to instantly compare odds for betting markets across Colorado sportsbooks. The Parlay Picker suggests additional entries based on your betting preferences, and the bookie earns just 2% commission on all profits, compared to a 10-15% vig at most other Colorado operators.
The process for betting on sports in Colorado will largely follow these steps, regardless of which sportsbooks you’re using:

Colorado sports betting is changing—here’s what’s new:
Colorado legalized sports betting in 2019 with the passage of HB1327. The Legislature passed the bill in May, though it needed voter approval because of the proposed tax increase.
This led to Proposition DD, which voters narrowly approved (51.4% to 48.6%). With the passage, Colorado legalized sports betting and was able to launch its industry in May 2020.
Bettors in Colorado must be at least 21 years old to place a wager. When betting online, you must be physically located within state borders, and you’ll be blocked from wagering if the app or browser cannot detect your location.
College sports betting is growing in popularity, and Colorado bettors will be happy to learn they can wager on collegiate athletics, including games with in-state teams. However, player props are prohibited at all times.
Here is a timeline of important events in the history of sports betting in Colorado.
Below is a list of all 13 online sportsbooks in Colorado:
Additionally, the following sportsbooks have since shut down their Colorado operations:
In addition to the online operations listed above, you can also gamble at any or all of the 12 retail sportsbooks in Colorado listed below:
When you register for a Colorado sportsbook, you’ll almost certainly receive a welcome bonus promotion. Thus, knowing the different types of bonuses that may be offered to you will help you time your registration to maximize the benefits.
Here are a few of the most commonly offered Colorado sportsbook promotions and bonuses that you’ll want to get to know.
Promo codes are not issued nearly as often as they used to be, as sportsbooks primarily offer opt-in promotions instead. Instead, referral codes are offered by sportsbooks so newly registered users can access the rewards while the referring user gets a kickback for bringing a new gambler to the platform.
If a promo code is available at a Colorado sportsbook, follow this process to redeem the code and claim your benefits.
In Colorado, roughly 99% of sports betting revenue comes from online sources, according to the Colorado Department of Revenue. The majority of this online revenue comes from mobile sports betting, as the apps are far more convenient than driving to a retail gambling facility.
With those figures in mind, having a great mobile app can lead to a large user base, as is the case for FanDuel and DraftKings, while a bad app can lead to closing down online operations altogether.
Below, we’ve compiled the ratings of all the mobile sports betting apps in Colorado in the Apple App Store and Google Play Store. These ratings are accurate as of March 2025.
| Sportsbook | Apple App Store Rating | Google Play Store Rating |
|---|---|---|
| Bally Bet | 4.3/5 | 4.4/5 |
| bet365 | 4.8/5 | 4.6/5 |
| BetMGM | 4.8/5 | 4.4/5 |
| BetMonarch | 4.3/5 | 3.5/5 |
| BetRivers | 4.8/5 | 4.7/5 |
| Caesars | 4.7/5 | 4.3/5 |
| Circa Sports | 3.4/5 | 2.4/5 |
| ClutchBet | 3.2/5 | 3.3/5 |
| DraftKings | 4.8/5 | 4.5/5 |
| ESPN Bet | 4.8/5 | 4.5/5 |
| Fanatics | 4.8/5 | 4.5/5 |
| FanDuel | 4.9/5 | 4.7/5 |
| SBK Sportsbook | 3.8/5 | 3.5/5 |
Sports betting winnings are a form of taxable income in Colorado, so you’ll need to report the totals when filing your returns. Colorado has a 4.4% tax rate on sports betting winnings regardless of your income bracket; this is in addition to the 24% federal rate.
If you make at least $600 from sports betting at a single bookie, that operator will send you a copy of Form W-2G to complete in your tax preparations. Otherwise, you will need to download the form from the IRS website.
Regardless of the amount of money you’re wagering, every sports bet carries risk; this is why most gambling operators have done away with the term “risk-free bets” (consider it a red flag if you see any that still use the term).
Ethical marketing practices are just one of the ways sportsbooks can practice responsible gambling, though the burden falls on all involved parties. Bookies should provide the tools for users to self-impose limits on money and time spent on their platforms while gamblers should abide by those limitations and inform themselves on warning signs of gambling compulsion.
Below are a few of the Colorado-specific responsible gambling resources:
One of the above resources is an application for Colorado’s gambling self-exclusion program. This allows individuals to voluntarily prohibit themselves from entering (or attempting to enter) gambling facilities and from accessing (or attempting to access) online betting accounts or face civil and/or criminal penalties.
While the program seems extreme, it can be a very effective deterrent for high-risk individuals. If you think you may be at risk, we strongly encourage you to consider applying for the program; if you’re already in the program, please keep with it!!
Colorado’s gambling history has already been turbulent, making predictions for the future of sports betting in the state a challenge. Betting handle numbers are strong, but nine online operators left Colorado in 2024; five others shut down in 2023.
We’ve seen similar mass exodus events in other states, and usually, this is a sign of market stabilization. There may yet be a few more sportsbooks that shut down in Colorado, but we don’t expect this would significantly impact betting revenue or the gambling experience.
Another area of concern is the potential for legalizing online casino gambling. This would likely lead to a drop in betting handle, with bettors wagering their money elsewhere; however, there is little legislative momentum, and Colorado’s retail casinos are strongly against legalization efforts.
Colorado’s sports betting industry has already been successful in generating tax revenue, with nearly $100 million raised so far. This money goes to responsible gambling initiatives, water projects, infrastructure operations, and other important efforts around the state.
Now that you’ve learned about the available sportsbooks, bonuses, and responsible gambling resources, it’s time to dig deeper to find the bookies that best align with your gambling objectives. Our sportsbook reviews have loads of info about the available sports each betting site has to offer along with details about their rewards programs, app functionality and features, customer service, and much more!
Good luck, have fun, and always gamble responsibly!!
Yes, there are many bonuses and promotions available for sports betting in Colorado. Sportsbooks will offer many daily promos like odds boosts and profit boosts, as well as new user bonuses like second chance bets and bet/get offers. Check out BettorInGreen.com for the latest promotional news at Colorado sports betting sites.
You can responsibly manage your sports betting activities by setting limits on the amount of time you’re spending at online and retail sportsbooks, setting a budget to ensure you’re only wagering within your financial limits, and keeping a manual record of the bets you’re making. We strongly recommend talking with someone you trust about your betting habits so they can help keep you accountable as you place your wagers.
If you have a dispute with a sports betting operator in Colorado, the first thing you should do is attempt to resolve the issue directly with the sportsbook. Failure to do so will cause more headaches down the line. If you cannot resolve the issue directly with the operator, you will need to file a written complaint to the Colorado Division of Gaming.
Sports betting impacts the Colorado economy by generating tax revenue for the state and through tourism dollars at retail sportsbooks. Colorado is expected to surpass $100 million in lifetime sports betting tax revenue in 2025.
Many of the same sports betting options that are available at online sportsbooks will also be available at Colorado casinos. You’ll still be able to craft parlays, as well as place your moneyline, spread, and totals wagers. However, you are unlikely to receive betting bonuses while gambling in person.
