Online gambling in Colorado centres on legal sports betting, pari-mutuel horse racing and daily fantasy; real-money online casino and poker aren’t legal here. This guide covers what’s legal, who’s licensed by the Colorado Division of Gaming, and how to get started.
Colorado runs one of the most competitive, consumer-friendly betting markets in the country. Rather than cap licenses, the state lets operators compete, so bettors have a dozen major apps to choose from. A distinctive feature sets Colorado apart: its sports betting tax funds the state’s water-conservation efforts. This Colorado guide covers what’s legal and how to start.

Is online gambling legal in Colorado?
Yes, for sports betting. Colorado voters approved Proposition DD in November 2019 and the market launched on May 1, 2020, regulated by the Colorado Division of Gaming (within the Department of Revenue). You must be 21 or older and physically located in Colorado to bet, confirmed by geolocation. The state permits betting on in-state college teams, though player props on college sports are banned. Real-money online casino is not legal in Colorado.
What’s legal online in Colorado, vertical by vertical
- Colorado betting apps: legal. Mobile betting on every major sport and league from a dozen major apps.
- betting on horses in Colorado: legal. Pari-mutuel wagering via ADW apps, plus live racing at Bally’s Arapahoe Park.
- Sweepstakes casinos: available, operating under the dual-currency model outside state gambling licensing.
- Online casino: not legal.
- Online poker: not legal.
- Prediction markets: offered under federal CFTC oversight rather than Colorado licensing; see our prediction markets guide.
- Daily fantasy sports and lottery: DFS is legal under its own rules; the Colorado Lottery sells tickets at retail.
The widest operator field in the US
Colorado’s philosophy is competition as consumer protection: with unlimited licenses and a low 10% tax on net proceeds, a large field of sportsbooks fights for players, which tends to mean sharper lines and stronger promotions than in high-tax states. The tax revenue is earmarked for the Colorado Water Plan, a genuinely unusual public-benefit tie-in, and since voters approved Proposition JJ in November 2024 the state keeps all of it rather than refunding anything above the old $29 million cap.
One change to note: under HB25-1311, signed by Gov. Jared Polis in May 2025, operators lost the ability to deduct “free bet” promotions from taxable revenue on July 1, 2026, which may gradually trim the biggest bonus offers. Fun fact: bet365 runs its US operation from the Denver area.
Colorado sportsbooks
Twelve major online sportsbooks are live, each tied to a casino in Black Hawk, Central City or Cripple Creek: FanDuel, DraftKings, BetMGM, Caesars, bet365, Fanatics, BetRivers, theScore Bet, Hard Rock Bet, Circa Sports, Bally Bet and BetMonarch. None is an American.Bet partner, so we cover them editorially. Our Colorado sportsbook guide has the full operator table with each casino partner, the college betting rules and the latest monthly figures.
Popular bets and Colorado sports
Colorado bettors play the standard markets: moneylines, point spreads, totals and parlays and same-game parlays. Local action runs across the NFL’s Broncos, the NBA’s Nuggets, the NHL’s Avalanche and MLB’s Rockies, plus the Colorado Buffaloes and Colorado State. Since Colorado allows in-state college betting, those games count too, though college player props are off the board. Football leads the handle every autumn.
Choosing a Colorado sportsbook
With one of the biggest fields in the country, Colorado rewards bettors who line-shop. Before you commit, weigh the welcome offer (safety-net first bet versus bonus bets), the depth of markets on the Broncos, Avalanche and CU, the quality of live betting and same-game parlays, and withdrawal speed. Because so many books operate here, you’ll often find the same game priced slightly differently across apps; keeping two or three accounts lets you take the best number every time.
Bet types explained
Most Colorado bettors get by with a few wager types. The moneyline backs a winner straight up (the Broncos, for instance) and a point spread adds a margin to balance favorite and underdog. A totals bet shifts the focus to combined scoring, parlays reward players who tie several picks together on one slip (every leg must hit), same-game parlays do that within a single Broncos game, and futures plus live betting round out the menu as the odds move during play.
Colorado’s market by the numbers
The Division of Gaming publishes monthly results. Coloradans wagered $388.1 million in August 2026 and $486.3 million in July, when the World Cup pushed soccer betting to record levels. Fiscal-year handle through August was $874.5 million, up 13.6% on a year earlier, with taxes up 20.2% to $7.7 million. Super Bowl LX alone drew $40.7 million in Colorado wagers.
Because the 10% tax applies to net proceeds, Colorado’s tax receipts are modest relative to its handle. That is by design: the state treats competition, not high taxes, as the main protection for bettors. With the free-bet deduction gone from July 2026, expect the state’s share to rise even though the headline rate stays at 10%.
How to start betting in Colorado
Signing up in Colorado is quick: be 21+ and inside Colorado, pick a licensed Colorado sportsbook, and create an account with accurate information for verification. Deposit, set your limits, place your first bet, and cash out whenever any offer’s conditions are satisfied.
Online casinos in Colorado
Colorado has regulations in place so that residents can only access authorized, licensed online sports betting sites, but casino games aren’t regulated online in the same way. No bill to legalize real-money online casino has passed, so there are no legal online casino sites or apps in Colorado, and no legal online casino bonuses to claim. Several of the state’s sportsbook operators, including BetMGM, Caesars, DraftKings, FanDuel and BetRivers, run online casinos in other states.
For the full picture, see our online casino guide, which covers the states where real-money iGaming is live.
Top land-based casinos in Colorado
Colorado’s commercial casinos are concentrated in three historic mountain towns, Black Hawk, Central City and Cripple Creek, with two tribal casinos in the southwest run by the Ute Mountain Ute and Southern Ute tribes. Notable venues include:
- Colorado Grande Casino in Cripple Creek, now the market-access partner for Hard Rock Bet.
- Ameristar Black Hawk, with spa facilities and several dining options.
- Century Casino, which operates in Central City and Cripple Creek and is bet365’s casino partner.
The legal age for casino gaming is 21; lottery games are open from 18.
Sweepstakes casinos in Colorado
Colorado players can access sweepstakes casinos, which use a dual-currency model: Gold Coins for free play and Sweeps Coins that can be redeemed for prizes. They operate outside state gambling licensing, so protections are thinner than at a regulated sportsbook. Names available to Colorado players include Chumba, LuckyLand Slots, WOW Vegas, Pulsz, McLuck, Crown Coins and Stake.us, alongside the four below. Our sweepstakes casino guide explains how the model works.
- Funrize: Welcome gift: 125,000 coins. No purchase necessary. 21+. Not available in CT, DE, ID, LA, MI, MT, NV, NJ, NY, RI, TN, WA, WV, WY; free-coin mode only in CA, IN, MD, ME, OK. Full terms at Funrize. Read our Funrize review Visit Funrize →

Horse racing betting in Colorado
Colorado bettors can wager on horse racing through ADW platforms such as AmWager, TwinSpires, FanDuel Racing, TVG, DRF Bets and DraftKings Horse, a separate product from Colorado sports betting. Live racing runs at Bally’s Arapahoe Park in Aurora, whose 2026 meet ran June 12 to August 16 and closed with the Mile High Futurity and Mile High Derby for quarter horses.

Is online gambling safe in Colorado?
Yes, as long as you use operators licensed by the Colorado Division of Gaming. Licensed apps are regulated, safeguard your deposits and verify your age and location on every bet. Offshore sites that aren’t state-licensed carry real risk to your money and data, so confirm a book is on the Division’s licensee list before signing up.
Responsible gambling in Colorado
Betting in Colorado should stay entertainment, not a way to chase money or claw back losses. Every licensed Colorado operator hands you deposit, wager and time limits plus cool-off and self-restriction tools, and the trick is to set them when you open the account rather than after a rough night.
If it stops being fun, that is your cue to step away. The Division of Gaming points residents to BetSmart Colorado and to 1-800-GAMBLER, free and confidential, which you can call or text. General advice is at GambleAware.org and in our responsible gambling guide.
Colorado gambling in 2027
No more free-bet deductions
Fiscal 2026-27 is the first full year in which operators can’t deduct promotional bets from taxable revenue. Bill sponsors estimated about $13 million in extra water funding, and welcome offers may tighten.
Online casino stays off the table, for now
No iGaming bill has passed in Colorado. Any 2027 proposal would have to win over a legislature that has so far preferred a sports-only model.
Arapahoe Park’s calendar
The 2026 meet returned to a summer window after 2025’s late September start. The 2027 dates approved by the Division of Racing Events will set the local racing calendar.
