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 Colorado sports betting brands like DraftKings, FanDuel, and BetMGM.
However, overseas sportsbooks such as BetOnline and BetUS 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 legal for Colorado residents to use and offer a strong alternative to domestic 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 like FanDuel and Caesars 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.

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

Reload Bonus

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.

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 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.

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.
