Is Sports Betting Legal in Colorado?
Yes, both in-person and online sports betting are legal in Colorado. Voters approved legal Colorado sports betting through Proposition DD in 2019, and the market officially launched in May 2020. Since then, Colorado has licensed dozens of operators, including both local sportsbooks and national brands.
Colorado residents can also explore overseas sportsbooks, which are legal to use and offer unique advantages like crypto support, broader markets, and bigger bonuses.

Current Legal Standing
Colorado has one of the most open and competitive sports betting markets in the U.S. All online sportsbooks must partner with a retail casino license holder in the state. As of 2025, over 25 mobile sportsbooks are active, including major Colorado sports betting brands.
However, overseas sportsbooks remain popular in Colorado due to their robust crypto support, lower fees, and greater market flexibility. These platforms operate outside U.S. jurisdiction but are accessible to Colorado residents and offer a strong alternative to domestic betting apps.
Recent Legislation Changes
Colorado continues to fine-tune its sports betting regulations. The Colorado Limited Gaming Control Commission made several updates in 2023 and 2024 to improve transparency in advertising and strengthen player protections.
Colorado’s regulatory environment is still evolving, but its foundation remains strong, with more innovations likely on the horizon.
Will Colorado Ever Expand Betting Further?
Colorado is likely to see continued expansion of Colorado sports betting rather than restriction. There is growing interest in adding political betting and expanding betting on high school sports, though both face significant legal and ethical hurdles.
A possible future bill could address prop bets on in-state college teams, especially with ongoing pressure from sportsbooks and universities. While no major overhaul is expected in 2025, the state has shown a clear willingness to evolve its framework as the national market matures.
Can You Play at Online Sportsbooks in Colorado?
What betting sites are legal in Colorado is a common inquiry, and there are many options in the state. Yes, residents can legally access a wide range of online sportsbooks in Colorado. This includes both state-regulated Colorado sports betting platforms and offshore sportsbooks based overseas.
While licensed apps are available, many Colorado players still choose offshore sites for higher betting limits, broader crypto options, and fewer restrictions on player props.
These sportsbooks are not governed by U.S. law but are widely used and legally accessible within Colorado. Just ensure the site is reputable and well-established.

We use a consistent, in-depth review methodology to evaluate Colorado sportsbooks. Our goal is to recommend only the safest and most rewarding platforms based on user experience, payout speed, sports coverage, and value-added features.
Welcome Bonus
Welcome offers are a key factor in evaluating sportsbook value. We look for large Colorado sports betting bonus amounts, fair rollover terms, and flexibility in how bonuses can be used. Crypto-specific bonuses also earn higher marks.
Safety & Security
We only recommend sportsbooks that are licensed in reputable jurisdictions and use industry-standard encryption protocols for sports betting in Colorado. Colorado sports betting platforms must also have a strong history of on-time payments and customer protection.
Payment Options
The best sportsbooks support a wide range of payment methods, including credit cards, e-wallets, and especially cryptocurrencies like Bitcoin, Ethereum, and Litecoin. We prioritize Colorado sports betting platforms with fast withdrawal times and no hidden fees.
Range of Sports
Whether you’re betting on the Broncos or UFC, Colorado betting apps should offer deep coverage of major leagues and niche events alike. We look at the breadth of markets available and the diversity of props and futures.

Even small improvements in odds at betting sites in Colorado can translate to big gains over time. We prefer Colorado sports betting platforms that offer low margins, early lines, and reduced juice promotions for long-term value in CO sports betting.

Bonuses at Colorado Sports Betting Sites
Online Colorado sportsbooks offer a variety of promos beyond just welcome bonuses. We break down the most common bonus types below.
Welcome Bonus
Welcome bonuses are designed for first-time users at CO online sportsbooks, often offering a deposit match (e.g., 100% up to $1,000). These deals typically come with rollover requirements and are ideal for users planning to bet consistently over time.
Reload Bonus
Reload bonuses give returning players a deposit match on future deposits, usually with lower match percentages than the welcome offer. Great for users looking to build long-term bankrolls.
Risk-Free Bets
A risk-free bet refunds your wager (often in site credit) if it loses. These are usually available on your first bet at CO sportsbooks after joining and help reduce early risk, especially on longshots.
Odds Boosts
Odds boosts increase the payout for specific bets, often tied to major sporting events. These are time-sensitive and useful for maximizing value on popular picks.
Bet Insurance
Bet insurance protects parlays or large bets by offering a refund (site credit or bonus funds) if one leg fails. This promotion suits users who favor high-risk, high-reward wagers.
Popular Colorado Sports Teams to Bet On
Colorado has teams in nearly every major sport, giving bettors year-round action across pro and college leagues.
Colorado NFL Teams
The Denver Broncos are the state’s flagship NFL franchise. Bettors love wagering on spreads, totals, and player props for games at Empower Field. NFL futures (like MVP or Super Bowl winner) are also big draws.
Colorado NBA and WNBA Teams
The Denver Nuggets are fresh off a championship and popular in futures, moneylines, and same-game parlays. The Colorado Chill is a former pro women’s team, but they don’t play in the WNBA currently. Nonetheless, fans can still find women’s pro basketball markets at top books.
MLB Teams in Colorado
The Colorado Rockies are a fan favorite for totals betting thanks to their hitter-friendly home park. Bettors also enjoy action on live in-game markets and alt lines.
Colorado NHL Teams
The Colorado Avalanche are perennial playoff contenders and draw heavy betting action on puck lines and player scoring props. NHL live betting is especially popular due to the game’s pace.
MLS Soccer in Colorado
The Colorado Rapids provide MLS action for soccer bettors. Popular markets include match result, both teams to score, and exact score wagers.
Colorado NCAA Teams
College fans in Colorado back programs like the Colorado Buffaloes (CU) and Colorado State Rams. NCAAF and March Madness action includes spreads, moneylines, and tournament futures.
Responsible Betting in Colorado
Colorado promotes responsible gaming through state-backed programs and awareness campaigns. Since a lot of money is being spent based on state revenue reports, there are clearly risks. Always use limits on your account and take advantage of time-outs or self-exclusion if needed.
