Colorado sports betting

Is sports betting legal in Colorado?

Yes. Colorado sports betting is legal through state-licensed operators, both on phone apps and at retail sportsbooks. In its September 5, 2025 Bet Smart release (opens in a new tab), the Colorado Division of Gaming said the only online gaming in Colorado is sports betting, and it counted 13 licensed online sportsbooks and 10 in-person ones.

That makes sports betting the sharp exception in Colorado's gambling law. Online casino games aren't licensed at all, and the Division says internet gambling with sites licensed elsewhere is illegal and has no Colorado recourse. If you want to bet online from Denver, Colorado Springs or Aurora with state protections, a Colorado-licensed sportsbook is the route the state recognizes.

For everything else Colorado allows, from the casino towns to the lottery, see the Colorado online casino hub and the Colorado gambling laws page.

When Colorado sports betting launched and who regulates it

Colorado's State Auditor dates the first year of sports betting regulation from May 2020 to April 2021, which puts the launch in May 2020. The regulator is the Colorado Division of Gaming, part of the Department of Revenue's Specialized Business Group, which also licenses the casinos in Black Hawk, Central City and Cripple Creek.

The Division's main site, sbg.colorado.gov (opens in a new tab), is the place to check licensing news and responsible-betting resources. Our sports betting laws page compares Colorado with other states.

Sports betting apps vs retail sportsbooks in Colorado

Colorado allows both, and the Division's 2025 count shows online books outnumbering retail counters. Here's how the two compare for a bettor.

We don't list operator names here because the Division's count is the figure on record, and licensees change. Confirm any app against the Division's own information before you deposit. If you're looking at casino-style apps instead, the mobile casinos Colorado page explains why none of those is licensed.

How Murphy v NCAA and the Wire Act shaped Colorado sports betting

Before 2018, the federal Professional and Amateur Sports Protection Act (PASPA) barred most states from authorizing sports betting. On May 14, 2018, the Supreme Court ruled 6-3 in Murphy v. NCAA (opens in a new tab) that PASPA's ban on state authorization violated the Constitution's anticommandeering rule, and the whole statute fell. That opened the door for Colorado.

The Wire Act still matters. It targets people in the business of betting who use wire communications for interstate bets, and the First Circuit held in January 2021 that it covers only sports-related bets. UIGEA also exempts intrastate bets authorized by state law with age and location verification, which is why state-licensed apps confirm where you are. Read more on PASPA and Murphy v NCAA and the Wire Act.

Offshore sportsbooks and Colorado: what the Division says

Offshore sportsbooks still advertise to Colorado bettors. The Division's What is Legal? page (opens in a new tab) says betting from Colorado with online sites is illegal even if the site is licensed elsewhere, and that a Colorado agency can't help you recover money from one.

There's a Colorado-specific example on record. Bovada, an offshore sportsbook and casino, lists Colorado as a restricted state on its own help page, and a trade report says Colorado sent it a cease-and-desist on June 4, 2024. Our Bovada review has the details.

How to confirm a Colorado sports betting app is licensed

1. Start at the Colorado Division of Gaming's site and look for its sports betting licensing information.
2. Match the app's operator name with the Division's information, not just the brand logo.
3. Download the app only from an official app store or the operator's own site.
4. Expect an age check for 21+ and a location check that confirms you're in Colorado.
5. Read the house rules on bet limits, voided bets and withdrawals before you fund the account.
6. Set deposit and time limits in the app on day one, if it offers them.

If an app or site doesn't check that you're in Colorado, or can't be matched to the Division, treat it as unlicensed. Our state regulators page lists the agency in every state.

Colorado sports betting age and ID checks

The minimum age for Colorado sports betting is 21, per the State Auditor's performance audit of the program. Expect a licensed sportsbook to verify your age and identity before you can bet or withdraw.

The Division's legality page doesn't state a separate casino or lottery age in the text on record, so check those rules directly with the casino or the Colorado Lottery. Our gambling age by state page compares limits across the US, and can I play at 18 explains the common exceptions.

Sports betting taxes in Colorado: W-2G, withholding and losses

Sports betting winnings are taxable federal income. The IRS W-2G instructions (opens in a new tab) set these rules for 2026 payments on sports and other wagering:

A worked example: a $10 parlay that wins $3,500 is 350 times the stake and over $2,000, so it meets the W-2G test. Winnings minus the wager are $3,490, under $5,000, so regular withholding wouldn't apply. Smaller wins without a form are still reportable. Colorado's own income tax treatment is a question for the Colorado Department of Revenue. See gambling taxes and can I deduct gambling losses.

What sports betting costs: the margin in dollars

Sportsbooks build a margin into their prices, so betting costs money over time like any other gambling. A simple illustration: if a book asks you to risk $110 to win $100 on each side of a game, it takes in $220 and pays out $210 to the winner, keeping $10. You'd need to win more than 52.4% of such bets ($110 ÷ $210) just to break even.

Parlays multiply that margin across legs, which is why they pay big and win rarely. No staking system or "lock" changes the math of the margin. Our house edge explained guide shows the same principle for casino games, and bankroll management covers setting a budget you can afford.

Federal bills that could change Colorado sports betting

Two federal debates could touch Colorado's market. The SAFE Bet Act of 2025 (S. 1033 / H.R. 2087) would put state-regulated sports betting under federal oversight and minimum standards. Separately, several 2026 prediction-market bills would define "casino-style game" and sporting events and bar federally regulated exchanges from listing contracts on them, according to a Congressional Research Service report from August 17, 2026.

Most of those bills had no recorded action beyond introduction or committee, per that report, and none had passed. Colorado's own framework stays in place unless Congress acts. Our prediction markets page tracks the federal side.

Bet Smart Colorado: responsible sports betting help

The Division's September 2025 release reminded Coloradans to play responsibly as the fall sports season began. Its state program, Bet Smart Colorado (opens in a new tab), offers responsible gambling information and support.

• Set deposit and time limits in your sportsbook app before the season starts, where available.
• Avoid in-game betting if you notice yourself chasing a result.
• Never bet money meant for rent, bills or debt.

The National Problem Gambling Helpline, run by NCPG, is 1-800-MY-RESET (1-800-697-3738), by call or text, any time. The national helpline page explains what happens when you reach out.
