FanDuel Sportsbook went live in Colorado on May 1, 2020, the day legal online betting started. Its license comes through Bally's Golden Gates Casino in Black Hawk.
FanDuel's best feature is its same-game parlay builder, and it regularly offers profit boosts on live same-game parlays. New customers get Bet $5, Get up to $350 in Bonus Bets ($50 a day for 7 days). Bet $5 or more on a given day and you get $50 in bonus bets, win or lose, for up to seven days. No Promo Code is needed.
You can bet moneylines, spreads, totals, parlays, player props, futures and live odds on the NFL, NBA, NHL, MLB, soccer, golf, tennis and UFC. Basketball is Colorado's biggest betting sport, so a Nuggets same-game parlay is the obvious local play, followed by the Broncos and the Avalanche. CU Buffaloes and Colorado State games are available as game lines only, because Colorado bans college player props.
DraftKings Sportsbook launched in Colorado in May 2020, in the first weeks of legal betting. It holds its license through Bally's Mardi Gras Casino in Black Hawk, where it also runs a retail sportsbook, and it signed a 2020 deal as a sports betting partner of the Colorado Rockies.
Regular bettors earn Crowns through Dynasty Rewards: one Crown for every $1 on parlays and same-game parlays, and one for every $2 on straight bets. New customers get Bet $5, Get $200 in Bonus Bets + 3 Months of NBA League Pass. The bonus bets are paid as $50 every 7 days over 21 days and expire 7 days after issue. No Promo Code is needed.
DraftKings covers moneylines, spreads, totals, parlays, props, futures and live betting on the NFL, NBA, NHL, MLB, college sports, soccer, golf, tennis and UFC. League Pass makes it easy to follow the Nuggets all season, and Avalanche puck lines and Broncos props are on the board every week.
BetRivers Sportsbook was one of four books approved on Colorado's launch day, May 1, 2020. It is run by Rush Street Interactive and licensed through JP McGill's Hotel & Casino in Cripple Creek.
Two features stand out. iRush Rewards earns points on every bet, and the Play+ prepaid card makes deposits and withdrawals quick. That matters more since August 2026, when Colorado banned credit card deposits. New customers get a Second Chance Bet on your first wager: if it loses, you get a bonus bet back. No Promo Code is needed.
The menu includes moneylines, spreads, totals, parlays, same-game parlays, props, futures and live betting across the NFL, NBA, NHL, MLB, soccer, golf, tennis and UFC. Broncos and Nuggets games draw the deepest markets, and college hockey fans can bet the Denver Pioneers on game lines. College player props are banned in Colorado.
Hard Rock Bet went live in Colorado on July 21, 2025, its ninth state. It is the newest big name among Colorado sportsbooks and is operated by Seminole Hard Rock Digital.
Bets earn points in Unity by Hard Rock, the rewards program shared with Hard Rock casinos and hotels, and weekly reward drops add bonus bets and parlay insurance. The welcome offer is Bet $5, Get Up to $500 in No Sweat Bets. Your first cash bet of $5 or more at odds of -500 or longer unlocks ten No Sweat Bet tokens, one a day for 10 days, each covering a bet up to $50. No Promo Code is needed.
You can bet moneylines, spreads, totals, parlays, same-game parlays, props, futures and live odds on the NFL, NBA, NHL, MLB, college sports, soccer, golf, tennis and UFC. A daily No Sweat Bet works well across a week of Avalanche, Nuggets and Broncos games. CU Buffaloes bets are limited to game lines.
bet365 went live in Colorado in September 2022 through Century Casinos. Colorado was its second US state.
Its best feature is Early Payout: a straight bet on the NFL, NBA, MLB, NHL or college football is paid as a winner if your team gets far enough ahead at any point. Watch & Bet streams some events to funded accounts. New customers get Bet $10, Get $200 in Bonus Bets, Win or Lose. You need a $10 deposit and a $10 qualifying bet within 30 days of signing up, and the bonus bets expire 7 days after issue. No Promo Code is needed.
bet365 is known for its in-play range, with live odds on the NFL, NBA, NHL, MLB, soccer, tennis, golf and UFC. Early Payout suits a Broncos moneyline or a Nuggets bet that builds a big lead. Same-Game Parlay+ combines same-game parlays from several games into one bet, but college player props stay off the board in Colorado.
Colorado voters approved sports betting through Proposition DD in November 2019, and it went live on May 1, 2020. The rules are simple, but a few catch people out. The Colorado Division of Gaming (Limited Gaming Control Commission) licenses and regulates every sportsbook below.
You must be 21 to bet, online or in a casino sportsbook.
You can open an account online, but geolocation checks that you're physically in Colorado when you bet. Visitors can bet too.

Colorado doesn't host a headline event in 2027, so the national calendar does the heavy lifting: Super Bowl LXI on Feb. 14 at SoFi Stadium, the men's Final Four at Ford Field in Detroit on April 3 and 5, and the Kentucky Derby on May 1. In between, Broncos, Nuggets, Avalanche and Rockies games give Colorado bettors plenty of local teams to follow.
