Colorado sports betting: legal sportsbooks & rules for 2026

Is sports betting legal in Colorado?

Yes. Colorado's path to sports betting ran through both the legislature and the ballot box.

• The General Assembly passed House Bill 19-1327 in 2019, but the measure referred the final question to voters as Proposition DD.
• On November 5, 2019, voters approved the measure by a narrow margin, authorizing regulated sports wagering and creating a dedicated tax structure that sends eligible revenue toward implementation of the Colorado Water Plan and related public purposes.

Colorado launched online and retail sports betting on May 1, 2020. The Colorado Limited Gaming Control Commission and Colorado Division of Gaming regulate the market.

• Bettors must be at least 21 and online wagers must originate inside Colorado, which means a sportsbook app checks geolocation before accepting a bet.
• Residency is not required: an eligible visitor can register and wager while physically present in the state.

The commercial framework is unusual in a useful way. Internet sportsbook brands operate through master licenses connected to Colorado's licensed casinos, concentrated largely in Black Hawk, Central City and Cripple Creek.

• That structure created room for one of the country's broadest operator fields rather than a small capped market.
• The exact app count changes as brands launch, leave, pause operations or rebrand, but current September 2026 industry trackers put Colorado at roughly 15 active consumer sportsbook apps.

Best Colorado sportsbook apps

Colorado's open market gives bettors far more choice than single-book or tightly capped states.

• Current industry trackers count about 15 live apps, and the lineup includes nearly every large national sportsbook plus several Colorado-focused or specialist brands.
• That depth makes Colorado particularly useful for line shopping: a half-point on a spread or a few cents on a moneyline can differ from one book to another, so having several legal accounts can help you compare before betting.

Other Colorado options include specialist and regional brands such as Circa Sports, BetMonarch, SBK, Bally Bet, Sporttrade and theScore Bet.

• Availability changes, so confirm that a book is currently accepting new Colorado customers before depositing.
• The sportsbook reviews directory explains our scoring process, while our sportsbook bonus guide explains how to read rollover, expiration and minimum-odds terms before claiming a promotion.

Which sports can you bet on in Colorado?

Colorado sportsbooks offer a broad range of professional and international sports. Denver's own teams create a year-round local calendar: the Broncos in the NFL, Nuggets in the NBA, Rockies in MLB, Avalanche in the NHL and Rapids in MLS.

• Bettors can also find golf, tennis, MMA, boxing, motorsports and major international soccer competitions.
• The important legal distinction is that Colorado allows college sports wagering at the game level but does not allow proposition bets on collegiate sports events.

Bet types & live betting in Colorado

Colorado bettors can use the same core markets found in other large regulated states: moneylines, point spreads, totals, parlays, futures, team props and live in-play markets.

• Pro-sport player props are widely available, while college proposition markets are restricted by rule.
• If you are new to the terminology, read types of sports bets explained and understanding odds and lines before placing a wager.

Colorado's large operator field makes live prices and parlay pricing especially worth comparing. Our live betting guide covers how rapidly odds can move during games, and the parlay guide explains why combining selections changes both payout and variance.

Retail sportsbooks in Colorado

Retail sports betting is centered on Colorado's historic casino towns. Black Hawk has the largest concentration of casino properties and is the state's most prominent in-person gambling destination.

• Central City sits nearby and offers a smaller, more historic casino environment, while Cripple Creek serves bettors farther south.
• The practical difference for Denver-area bettors is distance: mobile registration is remote, so most people do not need to drive to a casino town just to create an account.

Why Colorado still has no online casino

Colorado does not currently authorize a regulated real-money online casino market.

• Sports betting is legal statewide on approved mobile platforms, but casino-style slots and table games remain tied to the state's existing gaming framework rather than a licensed iGaming system.
• That makes Colorado very different from states such as New Jersey, Michigan and Pennsylvania, where online sportsbooks and online casinos operate side by side.

How Colorado compares to other states

Colorado's regulatory model combines a moderate headline tax rate with a large competitive field.

• The 10% tax on net sports betting proceeds is far below New York's 51% mobile rate and below Illinois's progressive structure, while sitting in the same broad low-to-moderate range as states such as Arizona and West Virginia.
• The number of available apps is also a major differentiator: Colorado has far more legal choices than single-platform markets and several more than tightly capped states.

The biggest 2026 change is not the 10% headline rate itself. It is what operators can deduct before that rate is applied.

• Starting July 1, 2026, HB25-1311 ended the deduction for free bets.
• That effectively increases taxable proceeds relative to the old system and can influence how aggressively sportsbooks price or market promotions even though the statutory rate still reads 10%.

How to sign up for a Colorado sportsbook

Colorado allows fully remote registration, so you can create an account without visiting Black Hawk, Central City or Cripple Creek. Identity checks and location verification still apply, and the app must determine that you are physically inside Colorado when you attempt to wager.

Taxes on winnings & Colorado sportsbook revenue

Sports betting winnings are taxable income. Federal rules can require Form W-2G reporting and withholding in qualifying circumstances, while Colorado state income tax may also apply. Tax treatment depends on the bettor's overall situation, so use a qualified tax professional for personal filing questions rather than treating a sportsbook statement as tax advice.

On the operator side, Colorado imposes a 10% tax on net sports betting proceeds.

• That is separate from the bettor's personal income-tax obligations.
• The July 2026 change matters because operators can no longer deduct free bets when calculating net sports betting proceeds, meaning the same nominal 10% rate can apply to a larger taxable base than under the previous promotional-deduction structure.

Responsible gambling resources in Colorado

Colorado's 2026 legislative changes make safer-gambling rules more prominent.

• The state added a six-deposit-per-gaming-day limit, prohibited credit-card sportsbook deposits, restricted sportsbook push notifications and text messages that solicit bets or deposits, and strengthened rules against advertising aimed at people under 21.
• A separate 2026 law also expanded Colorado's regulatory framework around voluntary exclusion from sports betting.

Our responsible gambling guide explains practical deposit limits, time-outs, self-exclusion and warning signs. Legal availability does not make a wager low-risk, and a large number of competing apps should not be treated as a reason to spread more money across more accounts.
