While Centennial State residents have considerable options for US-licensed sports betting in Colorado, there are a few restrictions. In this Colorado sports betting guide, we’ll answer the question ‘Is sports betting legal in Colorado?’ in detail, explain the best options for sports betting in the state, and explore why most Coloradans favor overseas sportsbooks. We’ll also list the best CO sports betting sites for betting on the NBA, NFL, MLS, and NHL.
Is Sports Betting Legal in Colorado?
Sports betting has been legal in Colorado since 2019. In 2018, the US Supreme Court repealed the Professional and Amateur Sports Protection Act (PASPA), which gave each state the right to regulate all forms of gambling. Within a year, Colorado became the seventh state to legalize and launch sports betting in 2020.

Current Legal Standing
Is online sports betting legal in Colorado? As of 2025, it is live and legal. Retail and online sportsbooks in Colorado can operate under a Colorado Division of Gaming license. In addition, the state’s two tribes are also authorized to offer sports betting under their respective compacts.
Each of the state’s 33 licensed casinos can obtain a license to offer retail and online sports wagering via virtual sportsbooks in Colorado or betting apps, and there are currently 14 licensed operators. A few months after Colorado’s first anniversary of sports betting, the state recorded an increase in revenue in August and an all-time revenue record in November, a sign of the industry’s rapid growth.
Recent Legislation Changes
Since launching sports betting in 2020, there have been a few ongoing efforts to expand Colorado’s betting market further and refine its existing legislative framework. On June 14, 2024, Colorado voters approved Proposition JJ, allowing operators to retain sports betting tax revenue for the Water Project Measure.
Most recently, in May of 2025, Governor Jared Polis signed HB 1311 into law. The new bill will phase out the law that allows sportsbooks to deduct promotional bets and credits from taxable revenue by 2026.
When Did Colorado Legalize Online Sports Betting?
Online sports betting in Colorado was approved in 2019, when voters approved Proposition DD, which authorized retail and online sports wagering. The legal market officially launched in May 2020, and the Colorado Division of Gaming has issued 14 online sportsbook licenses.
How Do the Gambling Laws in Colorado Compare with Neighboring States?
Colorado has established a dynamic sports betting market that has grown consistently since 2020. Compared to other states, Colorado betting laws are relatively progressive and flexible. Let’s take a closer look at how CO online sports betting laws compare with those of neighboring states.
Arizona
Arizona sports betting has been live and legal since 2021, roughly a year after Colorado’s launch and on the first day of the NFL season. The state allows retail and mobile sports betting exclusively via tribal casinos. Under the current legislation, Arizona can have up to 20 licensed operators.
Kansas
Sports betting in Kansas is also allowed at both the retail and online levels. The state launched its sports betting market almost exactly a year after Arizona, allowing residents to place in-person bets through its casinos or online sportsbook operators. Kansas is one of the few states allowing wagers on college sports (except for under-18 players).
Nebraska
Nebraska approved casino gaming at licensed racetracks in 2020. Retail Nebraska sports betting launched in November 2023, but it’s only permitted through state-authorized gaming operators. Online sports betting is still prohibited in the state, making overseas sportsbooks licensed outside the US the only viable option for betting in the state.
New Mexico
New Mexico online sports betting is still illegal, but promising legislative efforts are ongoing to bring mobile sports wagering to the state. Retail sports betting has been available through the state’s six tribal casinos.
Oklahoma
Oklahoma sports betting is still illegal, despite several attempts to bring some form of betting to the state. Residents cannot place sports wagers through tribal casinos or online sportsbooks.
Utah
Any form of betting or gambling in Utah is completely banned. The state prohibited gambling in 1927, and no active plans exist to lift the ban. There are no land-based casinos, racetracks, or even state lotteries. Only social sports betting, which doesn’t use real money, is permitted in Utah.
Wyoming
By contrast, online sports betting in Wyoming has been legal and operational since 2021. The state is known for its unusual approach to sports betting because it only allows online sports wagering. Residents can place bets via six online operators.
Texas
Despite several promising legislative efforts and progress over the years, Texas sports betting is still unregulated. Retail and online sports betting are prohibited, but things may change later this year. If HJR 134 passes for voter approval, we could see an amendment to the current retail sports betting laws.
Can You Play at Online Colorado Sportsbooks?
Online betting via Colorado sports gambling sites is permitted, provided the operator holds a valid gambling license from the Colorado Division of Gaming. The state currently allows up to 33 licensed sportsbooks, but there are currently 14 online operators. This number will likely increase as Colorado’s sports betting industry reports consistent growth.
Coloradans looking for more betting opportunities with a more diverse sports betting experience can turn to offshore sportsbooks. In many states where sports betting is legal, online sportsbooks licensed outside the US tend to be the go-to choice for bettors for several reasons.
Besides being able to rely on an established reputation, bettors choose offshore sites because they typically provide more competitive odds and a full slate of betting options across core sports. These sites might also have special features like odds boosts, large prize pool contests, March Madness offers, and risk-free bets.

Popular Sports
The Centennial State has a vibrant sports culture with teams in each major US sports league and high-profile collegiate teams. Whether you’re cheering the Denver Nuggets from Ball Arena or rooting for the Rockies, there’s plenty of action for Colorado online sports betting all year round. These are the most popular teams and events you can bet on at Colorado betting sites.
Denver Broncos (NFL)
Football betting made up nearly half of the Colorado wagers recorded in 2019, with thousands of Coloradans backing the Broncos. The Denver Broncos are a storied franchise in the NFL, boasting three Super Bowl titles and a passionate fan base. Despite facing several challenges in recent seasons, the Broncos are set to make a comeback and restore their standing in the AFC.
Denver Nuggets (NBA)
The Denver Nuggets are a powerhouse in the NBA’s Western Conference. The team has had several years of success, but the past three years have elevated them to greater success. They secured their first NBA title in the 2022-23 season, and their star player Nikola Jokic became the ninth player to win three MVPs over four seasons, joining legends like Larry Bird and Kareem Abdul-Jabbar.
Colorado Avalanche (NHL)
The Colorado Avalanche is the state’s NHL team, competing in the Western Conference of the Central Division. They’ve been a consistently popular choice for NHL betting in Colorado, and their recent 2022 Stanley Cup win has further solidified their status as an elite NHL team. Star players like Nathan MacKinnon and Cale Makar are favorites for player props and player futures betting.
Colorado Rockies (MLB)
The Rockies are an MLB team based in Denver that competes in the West Division. Despite struggling in recent years, they remain a betting favorite among local baseball fans, particularly for over/under betting due to Coors Field’s reputation as the most hitter-friendly ballpark in the MLB. They have yet to win a World Series and have made a single appearance in the series, where the Red Sox defeated them. In 2023, the Colorado Division of Gaming reported a betting revenue increase of 146.8% at Colorado betting sites, where basketball attracted the most wagers.
Colorado Buffaloes (NCAA Football)
Betting on NCAA football surges at online sports betting CO sites during Buffalo games, especially when they come into the game as underdogs under Coach Prime. Colorado bettors rally around the Buffaloes and often back them against the spread or place futures bets on conference wins. State-licensed Colorado sportsbooks restrict college player props.
Colorado Rapids (MLS)
The Colorado Rapids are the state’s MLS team, competing in the Western Conference. Their first and only MLS Cup win was in 2010, before they hit a three-year slump, missing the playoffs in three consecutive seasons. However, they still enjoy a loyal fan base and are a fairly popular option for Colorado online sports betting, particularly on goal totals, in-game lines, and live betting.
