Colorado sports betting is more popular than ever! With NFL betting in Colorado just around the corner, Colorado bettors will be able to fire up NFL Sunday Ticket and wager on player prop bets, same-game parlays, and access all of the great betting markets through legal sportsbooks.

With Colorado sports betting legal, fans can now wager on their favorite Colorado sports teams like the Denver Broncos, Colorado Rockies, and Colorado Avalanche. If you are new to online and mobile betting, there is a lot to cover.

Is Sports Betting Legal in Colorado?

Legalized sports betting finally came to Colorado in 2020. The state takes sports betting revenue from all the Colorado sportsbooks, and each online sports betting establishment is required to gain a license before beginning operations.

Most, if not all, of these online sportsbooks offer popular sports like football, basketball, baseball, hockey, college sports, and even niche options like esports betting. With bonus bets available from many major sportsbooks, you can earn more than ever if your first bet wins.

Here are the best online casinos you can access in Colorado.

BetMGM Sportsbook

BetMGM Sportsbook is one of the most trusted names in the world of sports betting. With a well-established reputation built in Las Vegas, BetMGM brings some of the most comprehensive betting markets, competitive odds, and welcome promotions to the table.

Right now, BetMGM is giving your first bet more chances to hit. After making a minimum deposit, it’s time to place your first bet. If your bet wins, you are golden. If not, you will receive bonus bets in the amount of your wager to try again. At BetMGM Sportsbook, your first bet means more.

FanDuel Sportsbook may be the most recognizable online sportsbook in the world. That said, you don’t get to such a respected place in the industry without doing a lot right. FanDuel has one of the smoothest sportsbook apps out there, plus a plethora of fantastic features.

FanDuel also happens to have one of the very best welcome offers in the business. Sign up today and make a minimum deposit of $5 to get started.

The key to a really great Colorado online sportsbook is reliability. BetRivers Sportsbook has carved out a place for itself as one of the most trustworthy online sportsbooks in the business. With great welcome offers, tons of sports betting markets, and excellent customer support, BetRivers does all the little things well.

As it turns out, BetRivers also believes in second chances for new customers. Right now, you can place your first bet with BetRivers and earn your wager back if it loses. Think of it as a second chance to make something special happen the first time around.

Fanatics Sportsbook

A relatively new kid to the party, Fanatics Sportsbook is already making a tremendous name for itself. That’s what happens when you have one of the smoothest, most intuitive sports betting apps on the market.

Fanatics is also unique in that it has two different offers depending on your location. In three states, new users can earn a chance to receive $300 in bonus bets by making $30 in qualifying wagers. Everywhere else, new users can get a no-sweat bet worth up to $1,000 if their first wager loses.

Legal Colorado Sports Betting Bonuses

Before signing up for one of the many Colorado sportsbooks, you need to know about the most crucial thing: welcome bonuses. There are three primary categories that these welcome bonuses fall into, each of which offers new players a little something different.

Bonus Bets

This is one of the two most common welcome bonus types. In this situation, new players sign up, use a promo code (not always), make an initial deposit, and place their first bet. Sometimes, that first bet is rewarded with bonus bets regardless of the outcome. Other times, you have to win your first bet to garner the bonus bets.

Let’s look at the FanDuel Sportsbook promo to start. There isn’t a promo code to start; sign up, make a qualifying deposit, and place a first bet of $5 or more. If your bet wins, you'll receive $300 in bonus bets that must be used within seven days, or they will expire. Still, there’s nothing wrong with getting $300 in bonus bets for your first correct wager.

Second Chance/No Sweat Bet

The other common welcome bonus is the second-chance/no sweat bet. The process is similar, requiring you to sign up, use any required promo code, and make a deposit. The difference here is that you can bet whatever you want with your first wager. There are typically limits on how much you can wager, but we’ll get to that next.

Make your first bet with your sportsbook of choice. If you win, that’s the best-case scenario. If you lose, however, you will get your wager back in the form of bonus bets to try again. For example, BetRivers has a second-chance bet offer of up to $500. It is never ideal to lose your first wager, but you can at least breathe easy knowing that you have another shot to get it right.

Deposit Match

Finally, there is the deposit match bonus. Unlike other sportsbooks that offer bonus bets for winning or losing your first bet, this one works a bit differently. Instead, you get guaranteed bonus bets as part of the signup process.

Sign up with a sportsbook offering a deposit match bonus. When you make your first deposit, the sportsbook will match that deposit up to a certain amount. A common example is a 100% deposit match up to $500. That number varies from sportsbook to sportsbook, but there is nothing quite like doubling your bankroll before even making your first bet.

How to Start Betting on Colorado Sports Teams

Ready to jump into Colorado sports betting? The process is easier than you think. Sports fans, you can bet on sports in no time by following our steps below. Remember that this only applies to Colorado residents; otherwise, you will not be able to use Colorado sports betting sites (just offshore sportsbooks).

Choose from One of Many Colorado Sportsbooks

Perhaps the most challenging part of your legal Colorado sports betting journey is choosing a sportsbook. Most online sportsbooks are pretty similar, with the difference coming in their welcome offers. Find the one that most appeals to you (if they have a sportsbook app, it’s even better).

Make a First Deposit

Before doing anything, check with these online sportsbooks to see what the prerequisites are for the welcome bonus. Most have a minimum initial deposit, but there can be things like a maximum wager as well. Make a qualifying first deposit, and you’re ready for the next step before you can legally bet.

Place a Bet

While most Colorado sportsbooks offer bonus bets of some type, some qualifications must be met to earn those bonus bets. If you’ve already met the minimum deposit, it is now time to place a qualifying first bet. Check for a promo code as well. In some cases, you won’t get the bonus bets unless your bet wins. Check the fine print and meet those online sports betting requirements.

Collect Your Bonus

So long as you have met all of the legal sports betting requirements, bonus bets should be yours (unless your bet wins and the promo code is for a no-sweat bet). Keep in mind, you can’t withdraw anything additional unless your bonus bets win. Choose your wagers responsibly and ensure to follow responsible gambling protocols. There are problem gambling tools available at each of the online sportsbooks if you need help.
