Legal Colorado Betting Alternatives

Colorado is one of the few lucky states in the U.S. to have legalized online sports betting and to license private owned betting companies. But players that want to continue to find new sign-up bonuses, try a different approach to sports betting, or just check out some different betting apps, have several other options that are available in the state. It's possible to legally compete for real money at these apps, and even play casino games.

Social sportsbooks and casinos operate under the sweepstakes model, and offer a similar experience to the real thing. DFS and pick'em let players draft their own fantasy team that score points based on the real athlete's performances. Prediction markets let users buy/sell/trade contracts on the outcome of real events. Click one of the boxes below to find out more, and to find available bonuses in Colorado.

Common Questions in Colorado

We answer some questions about betting, bonuses & gambling from our Coloradan visitors.

Is sports betting actually legal in Colorado?

100% legal, both online and in-person. They flipped the switch in May 2020 and it’s been wide open ever since.

Can I play real-money online casino in Colorado?

No online casinos are still prohibited. It is however possible to play casino games at social casinos. 

Why do sportsbooks ask for part of my SSN?

Anyone asking for your social security number is bound to make you skeptical, even if it's just the last 4-digits. But there is actually a perfectly logical explanation for this. It's a government requirement. This rule is in place both to help preventing fraud and identify theft, but also because the IRS needs confirmation to be able to send out the required paperwork if you should win really big. 

Will the bonus terms trick me?

If you read them, definitely not. But it's common for players to ignore or misunderstand some part of the T&C's, which can make them feel frustrated or tricked when it prevents them for cashing out the profits.

In order to avoid this, we strongly recommend always looking through the terms before claiming a bonus. Minimum odds, turnover requirements, min/max deposits, eligible payment methods and promo-specific restrictions are especially important. 

What’s the minimum age to bet in Colorado?

For sports betting, the minimum age is 21+ with no exceptions. Federally licensed prediction markets may accept players from 18 and above, but most of them generally stick to 21.

Do I have to pay taxes on my wins in Colorado?

Yeah, the state hits you with 4.63% flat tax on gambling winnings (they changed it in 2024). Anything over $1,200 gets auto-reported to the IRS and they’ll withhold 24% federal right away on big hits. Losses can offset wins though, so save those tickets.
