How Sports Betting Became Legal in Colorado
Colorado’s path to legal betting followed a clear sequence of events.
- May 2018: The U.S. Supreme Court struck down PASPA, the federal law that had blocked most states from offering sports betting. This opened the door nationwide.
- November 2019: Colorado voters narrowly approved Proposition DD, authorizing regulated sports wagering.
- May 1, 2020: The market officially launched, with online and retail betting going live the same day. FanDuel, DraftKings, and BetMGM were among the first apps.
- November 2020: Voters passed Amendment 77, which removed the old $100 maximum bet limit and gave casino towns more control over game types.
The result is a mature, well-established market that has been running for over five years.
Where Colorado Betting Money Goes
Here’s a detail most bettors don’t know. Tax revenue from Colorado sports betting is directed largely toward the Colorado Water Plan, funding water conservation and infrastructure across the state.
The tax rate sits at 10% on net sports betting proceeds, meaning the taxable amount after winnings are paid out. So every legal bet placed in the state quietly supports water projects, an unusual and specific use compared to most states.
Online Sports Betting in Colorado
This is where Colorado shines. The state runs a mobile-first model, and the app selection is one of the deepest in the nation.
How the market is structured: each licensed Colorado casino can partner with one online operator, which creates a marketplace of many independently branded apps all competing for your business.
Roughly how many apps are live: industry sources have reported somewhere between a dozen and 16-plus licensed online sportsbooks operating through 2026, with the exact number shifting as licenses are approved. Major national brands available include:
- FanDuel Sportsbook
- DraftKings Sportsbook
- BetMGM
- Caesars Sportsbook
- bet365
- Fanatics Sportsbook
- BetRivers
- Hard Rock Bet
Because the state regularly approves new licenses, the lineup keeps evolving. Always confirm an app is licensed before signing up.
One key feature: you can register and fund an account from anywhere inside Colorado’s borders. You don’t have to visit a casino in person first, unlike some other states.
Retail Sports Betting in Colorado
Prefer betting at a counter? Colorado has physical sportsbooks located inside casino properties in its three historic gaming towns:
- Black Hawk
- Central City
- Cripple Creek
These retail books let you place bets in person and often include lounges to watch games. They operate under the same Division of Gaming oversight as the apps.
The Rules You Need to Know
A few specifics keep you on the right side of the law:
- You must be 21 or older. This applies to residents and visitors alike.
- You must be physically located in Colorado when placing a bet. Apps use geolocation technology to confirm this. Being a resident isn’t enough; you have to be inside state lines at the moment you wager.
- Only licensed operators are legal. Offshore or unregulated sites are not licensed in the U.S., even if they advertise to Colorado players. Sticking to state-licensed apps means your funds and disputes are protected by the regulator.
- No statewide maximum bet. Since Amendment 77, there’s no state-imposed cap. Individual sportsbooks set their own limits.
What Else Is Legal (and What Isn’t)
Colorado’s gambling landscape goes beyond sportsbooks:
| Activity | Legal in Colorado? |
|---|---|
| Online sports betting | Yes |
| Retail sports betting | Yes |
| Daily fantasy sports (DFS) | Yes |
| Online horse racing betting | Yes |
| Sweepstakes casinos | Yes (social model) |
| Prediction markets | Emerging, federally regulated |
| Real-money online casino games | No |
The big exception: online casino gambling (slots, table games) remains illegal under Colorado law. Only sports betting and a handful of related products are permitted online.
Responsible Gambling Protections
Colorado law requires licensed operators to build in safeguards. Every legal app must:
- Provide responsible gambling information and resources
- Let you self-exclude if you need to step away
- Offer tools to limit deposits and wagers
- Verify age, identity, and location before accepting bets
These protections are part of what separates a licensed Colorado sportsbook from an offshore site with none of the same accountability.
How Colorado Compares to Its Neighbors
Colorado is notably more open than several nearby states. Its combination of full statewide mobile betting, a huge app selection, and remote sign-up puts it among the friendliest markets in the country for bettors. States like Wisconsin, by contrast, still restrict most legal betting to in-person tribal casinos.
