Sports betting is legal in the state of Colorado, both online and at physical retail sportsbooks. However, that doesn’t mean it’s your only option for wagering. There’s a thriving community of international sportsbooks that accept Colorado players, offering features, bonuses, and markets many regulated apps don’t. That said, online betting comes with risks and considerations you need to understand before you place your first wager.
In this article, we’ll show you how to bet on sports in Colorado, explain the difference between regulated and international sportsbooks, and highlight the best international sportsbooks Colorado bettors should consider for 2026.

Is Sports Betting Legal in Colorado?
Yes. Online and retail sports betting have been legal in Colorado since May 2020 following the passage of legislation including Proposition DD in 2019. Bettors must be 21 or older and physically inside Colorado when wagering with regulated sportsbooks.
The Rise of International Colorado Sportsbooks
Even though legal sportsbooks are widely available inside Colorado, international sportsbooks remain popular for several reasons:
- Better odds and lines in many markets.
- More generous bonuses and promotions.
- Higher limits on certain bet types.
- More niche markets and exotic prop betting than many regulated books offer.
However, there are important differences between regulated sportsbooks and international options:
| Pros | Cons | |
| International | Better odds and more marketsBetter bonuses and generous promosHigher betting limitsMore sportsbooks to choose fromMore payment methods including crypto | International licensingNo consumer protectionsAmbiguous legal clarityNo mobile apps available |
| Regulated | State-mandated consumer protectionsFaster traditional payment methodsQuick, reliable customer serviceLegal clarityMobile apps available for download | Less competitive odds and fewer marketsLess generous bonusesLower betting limitsFewer sportsbooks to choose fromFewer payment methods and no crypto support |
Difference in consumer protections is a key point: regulated sportsbooks are overseen by the Colorado Division of Gaming, whereas international sites are generally licensed outside the U.S. and not subject to Colorado rules. This means dispute resolution and enforcement are more challenging with international operators.
Colorado Sports Betting Apps & Mobile Betting
Colorado has numerous legal sports betting apps you can download from the Apple App Store or Google Play.
International sportsbooks don’t typically offer native app downloads in the App Store/Play Store due to platform restrictions. However, many support Progressive Web Apps (PWAs) that provide a full mobile experience right in your browser.
How to Bet on Sports in Colorado
Here’s how to get started:
- Pick a trusted online sportsbook that accepts Colorado bettors.
- Visit the operator’s website and create your account.
- Complete the registration form with your information.
- Opt into any welcome bonus or promotion you qualify for.
- Make your first deposit with an approved payment method.
- Review bonus terms carefully to avoid missed opportunities.
- Verify that bonus or free play funds are in your account.
- Explore the available sports, events, and bet types.
Pro Tip: If you stick with reputable international sportsbooks and use cryptocurrency for transactions, online betting can be reasonably safe and fast.
Betting Safely With International Colorado Sportsbooks
Sports betting isn’t regulated in Colorado when using international platforms, meaning bettors lose some protections found with regulated books.
- Verify the sportsbook’s license (even if it’s not U.S.-based).
- Look for public payout history and independent reviews.
- Understand banking and withdrawal expectations.
- Know what to do if there’s a dispute.
- Set personal limits and use responsible gambling tools.
Be sure to protect yourself when betting online. Check out these simple tips to help mitigate risk:
- Use only OddsTrader-recommended operators.
- Start small and test withdrawals first.
- Use cryptocurrency for faster, more reliable transactions.
- Never leave large balances. Withdraw profits regularly.
- Diversify across 2-3 books.
And lastly, here are some red flags to avoid when choosing a new sports betting site:
- Lack of HTTPS: If a site isn’t secure, it’s a big red flag.
- Vague terms & conditions: Ambiguity can lead to problems down the line.
- Poor customer support: Customer service should be front and center, responsive, and helpful.
- Unclear payout structures: If payout rules and timelines aren’t transparent, be wary.
Bottom Line: Millions of Americans use online Colorado betting sites every year without major issues, but the key is choosing reputable operators with proven histories.
