Colorado Sports Betting Overview 2025 (Updated: December)

Colorado sports betting is live and legal. The table below summarizes the legality status of different forms of betting in the state.

Is Sports Betting Legal in Colorado?

Yes, sports betting in Colorado is legal and accepted. The Centennial State has about 20 licensed operators, providing a great mix of sports betting markets and player bonuses. State residents can wager on their favorite sports and teams using these online sportsbooks as well as offshore sites, betting apps, or retail outlets.

Online Sportsbooks

Online sports betting in Colorado is legal. This came about after the State-wide referendum held in 2019. As a result of the new law, online sportsbooks could partner with existing casinos to offer both in-person and online betting. This means that if a casino wanted to start offering sports betting, it’d have to partner with a sportsbook to develop a sports betting app. As of December 2025, there are 20 active state-licensed sportsbooks in Colorado.

Land-based Betting in Colorado

Just like online betting, land-based sports betting in Colorado is allowed and legal. You can find a variety of establishments across the state accepting sports bets, including:

• Barstool Sportsbook at Ameristar Black Hawk
• Betfred Sportsbook at Saratoga Casino
• BetRivers Sportsbook at McGill’s Hotel and Casino
• Caesars Sportsbook at Isle Casino Blackhawk
• Caesars Sportsbook at Lady Luck Casino
• Colorado Grande Casino
• DraftKings Sportsbook at Mardi Gras Casino Black Hawk
• Elite Sportsbook at Red Dolly Casino
• Johnny Nolon’s Casino
• Maverick Sports at Grand Z Casino
• Sasquatch Casino
• Sportsbook at Monarch Casino Black Hawk
• TwinSpires Sportsbook at Bronco Billy’s
• Wild Card Saloon
• Woody’s Sportsbook at Wildwood Casino
• Johnny Z’s Casino
• The Lodge Card
• Z Casino

Colorado Horse Racing & Off Track Betting

Horse racing is a popular sport in Colorado, even though the State only has one licensed track. Bally’s Arapahoe Park in Aurora began live racing for the first time in 1984 and has run live racing every season since then. The only exception was in 1985.

Off-track betting is also available and legal, with a limited number of outlets across the State. These are mainly located in Sheridan, Commerce City, Grand Junction, and Pueblo.

Since many Colorado horse racing fans do not live close to these cities, they opt to use online sportsbooks that are equipped to provide extensive horse racing coverage. These include XBet and BUSR.

Offshore Online Sports Betting in Colorado

Offshore betting in Colorado remains an overall better alternative to state-licensed sportsbooks. Without the very strict and expensive rules, offshore platforms are free to offer superior player bonuses and enhanced odds. Moreover, they can include a wider selection of sports, including college sports, and offer special features, such as live streaming.

If you’re interested in Colorado sports betting online and are looking for an offshore platform, there are some important facts that you need to keep in mind. First, an offshore sportsbook is one that is not based or licensed anywhere within the United States. Second, offshore sportsbooks can be licensed or unlicensed, but we recommend choosing the licensed ones.

All the Colorado sports betting sites listed in this guide are located offshore. Before ranking them, we carried out extensive research and analysis. Apart from seeing that they were safe and provided a superb user experience, we also ensured that they have a long track record of paying out to players promptly.

Colorado Daily Fantasy Sports

Daily Fantasy Sports (DFS) have been legal in the State since 2016. The two main licensed providers are FanDuels and DraftKings. Both operators provide a range of sports that include basketball, baseball, golf, and tennis.

Colorado Casino Laws

Colorado’s casino laws are far more restrictive than their sports betting counterparts. Whilst land-based casino games are allowed with restrictions, no form of Colorado online gambling, including casino apps, is allowed.

Land Based Casinos

Since the 1991 law that permitted land-based casino games, the State has over 30 licensed operators.

Colorado Gambling Taxes

Residents of Colorado are subject to both state and federal gambling taxes. Winnings arising from Colorado sports betting sites or any other mode are subject to a flat income tax rate of 4.63%.

Federal tax is also flat, at 24%. However, it is only payable if you surpass certain thresholds. These involve winning:

• $600 or more if the amount is at least 300 times the wager
• $1,200 or more in winnings from Bingo or slot machines
• $1,500 or more in winnings from Keno
• More than $5,000 in winnings from a poker tournament
• Any winnings subject to a federal income tax withholding requirement

In most cases, you’ll be allowed to deduct your buy-in or wager before declaring your income. You could also deduct losses as long as they are itemized on the appropriate form.

If you would like to find out more about gambling tax rules, we strongly recommend that you get in touch with a tax professional.
