The Colorado sports betting cupboard has 20 online sportsbooks, like DraftKings, FanDuel, BetRivers, BetMGM, Fanatics, and Caesars, which means CO sportsbook promos are generous. This guide will highlight sign-up bonuses from the best sportsbooks while emphasizing Colorado’s top five best betting offers.

Top CO sports betting bonuses

  • Top-tier app experience.
  • Same Game Parlays and SGP+.
  • Extensive promos and odds boosts.

FanDuel Review

FanDuel reigns supreme right now as the No. 1 betting site in America. And it has largely earned that spot on the strength of superior brand recognition, an easy-to-use product, an overwhelming number of markets for North America’s most popular sports, and representation in every state in which it is permitted to offer legal sports betting.

Caesars Sportsbook Review

Caesars is proving to be one of the most aggressively expanding brands in sports betting. Unfortunately, like all major U.S. sportsbooks, they are quick to limit you if you go on a tear and their odds boost promos offer low maximum bet limits.

No Sweat First Bet up to $1,000


  • Lots of promos and odds boosts.
  • Wide range of sports and bet types.
  • Seamless integration with DFS.

DraftKings Review

DraftKings had a solid reputation as the leading DFS provider in the country, so the shift to legal sports betting felt natural. They offer one of the most voluminous collections of ongoing promos and odds boosts in the industry as they cater to the beginner crowd. However, their reputation has dwindled as outspoken CEO Jason Robins leads the charge of the anti-profitable bettor mentality that runs rampant amongst sportsbooks that are quick to limit winning players.



Up to a $250 Second Chance Bet


  • Competitive odds across all markets.
  • Live betting section is well organized.
  • Earn iRush Rewards from betting activity.

BetRivers Review

BetRivers is in Colorado! BetRivers has a welcome bonus of up to a $250 second chance bet. Use promo code SBRBONUS upon sign-up to claim.

Must be 21+. If you or someone you know has a gambling problem, call 1-800-GAMBLER.

BetMGM is one of the top-rated sportsbooks in the U.S. offering some of the best live betting odds in the industry. They’re also the largest iGaming operator across the U.S.



Up to a $250 Bonus Bet


  • Massive selection of markets.
  • Easy-to-use interface.
  • Wide variety of banking options.

Betway Review

While this book won’t wow you with its design, you won’t find many apps easier to navigate – or with the sheer volume of sports markets Betway offers. And although you'll find more generous signup offers elsewhere, Betway remains a strong global sports betting brand that deserves to be mentioned among the second-tier sportsbook options in the U.S.



Get up to $250 in Bonus Bets


  • Great user interface.
  • Deep selection of bets in major sports.
  • Ongoing promotions for recurring players.

ClutchBet Review

Bringing its successful track record from Australia to the U.S., ClutchBet is a solid addition to the Colorado, Iowa, and Louisiana sportsbook markets.

All Colorado sportsbook promo codes and bonuses

Colorado’s appetite for legal online sports betting is evident in that 20 operators are active. With almost two dozen options and licenses to spare, each sports betting site is jockeying for position and market share in the Rocky Mountain State. Of the 20, only five require bettors to enter a promo code at the time of the first deposit: bet365, BetMGM, BetRivers, Caesars, and SuperBook.

While most welcome bonuses are first-bet insurance or bonus bets, some operators, like Betsafe and Tipico, offer the rarely-seen deposit match bonus.

The welcome bonus amounts are just the tip of the iceberg when it comes to Colorado sports betting. Here's a quick breakdown of my five favorite sportsbooks in the states, including more details about the value of the sign-up offers.

1. FanDuel CO welcome offer 🔵


Bet $5, Win $150 in Bonus Bets

21+. Gambling Problem? Call or TEXT 1-800-GAMBLER

The best online sportsbook in Colorado has a welcome bonus for new players. FanDuel offers a bet $5, win $150 in bonus bets reward for anyone who wins a qualifying wager on any available betting market. No FanDuel promo code is required. FanDuel also has some of the best Big Game boosts and a selection of props.

  • Available via the FanDuel app only.
  • Minimum deposit of $10 is required.
  • Make an initial wager of $5. If it wins, FanDuel will credit your account with $150 in bonus bets.
  • If your first bet loses, you'll receive zero bonus bets.
  • Bonus bets will hit your account within 72 hours of your first wager settling.
  • Bonus bets must be used within seven days
✅ Low initial risk required❌ Quick expiry
✅ Bonus can be split into multiple bets❌ Available in the app only
✅ Only a $10 min deposit required❌ First bet must win

What does the promo mean for you?

FanDuel’s Colorado welcome promo means new players can get $150 in bonus bets in exchange for any wining wager of $5 or more. If your bet loses, you do not earn the bonus. 

How much money can be earned with the promo?

Once you receive your bonus bets, you cannot withdraw them. Instead, you must use them to wager further with the sportsbook. So, the amount of real cash you can earn will depend on how you want to use the bonus funds.

Why this bonus is better than others

FanDuel does require you to win your first bet in order to collect this bonus, which is a bit of a bummer. However, if you do collect $150 in bonus bets, you can use them as freely as you like. Make one big $150 bet or 150 smaller $1 bets. You have complete freedom, which most similar offers don't match.

2. DraftKings CO welcome offer 👑


No Sweat First Bet up to $1,000

21+. Gambling Problem? Call or TEXT 1-800-GAMBLER

DraftKings’ current welcome bonus is perfect for newbies. No DraftKings promo code is required to get in on the $1,000 No Sweat first bet offer. DraftKings also sports some of the top super boosts out of any sportsbook, especially when major events like the Super Bowl or March Madness roll around. 

  • You must deposit at least $5 and place a qualifying wager of $1 or more on any sport.
  • If your bet loses, you'll receive your stake amount back as a single bonus bet, up to $1,000.
  • The bonus bet cannot be withdrawn as cash or split into smaller chunks.
  • Bonus funds must be used within seven days.
✅ No promo code required❌ First bet must lose to qualify
✅ Only a $1 initial wager needed❌ Seven days to use bonus
✅ High max. value
✅ Easy to read terms and conditions

What does the promo mean for you?

This promo is a straightforward first-bet insurance offer. If you lose your first qualifying bet on DraftKings, you'll get a refund via a bonus bet up to the $1,000 maximum limit. You must then use the bonus bet to make another wager, giving you a second chance to pick a winner. 

How much money can be earned with the promo?

The face value of this promo is $1,000, at the upper limit. However, you have to lose your first bet in order to collect, so don't be fooled by the marketing language. If you do collect a bonus bet and pick a winner, your payout won't include the original bonus bet amount. So you could come out with a total loss, depending on the odds of your bet.

Why this bonus is better than others

This bonus is better than others because of its potentially high value. Not many sportsbooks offer welcome bonuses into the four-figure range.

3. BetMGM CO welcome offer 🦁


Bet $5, Get $150 in Bonus Bets

21+. Gambling Problem? Call or TEXT 1-800-GAMBLER

BetMGM recently unveiled a special welcome offer to celebrate the pro football postseason and championship game. It has paused its typical first-bet insurance deal in favor of a bet $5, get $150 in bonus bets. If you register a new account with the BetMGM bonus code SBRBONUS and make a first bet of at least $5, you'll claim $150 in bonus funds.

  • The bonus bets come in six (6) $25 chunks.

✅ Low minimum deposit❌ Lower total bonus value
✅ Guaranteed bonus bets❌ Bonus bets expire in a week
✅ Small first risk of just $5

What does the promo mean for you?

BetMGM's promo is pretty simple. If you bet at least $5 on your first real money wager after creating your account, you'll earn $150 in bonus bets. They come in six $25 slices and enable you to make additional wagers on the sportsbook. 

How much money can be earned with the promo?

The face value of this bonus is $150. However, you cannot cash that amount out directly. You must use the bonus bets to make more wagers on BetMGM, so your total potential profit is determined by the picks you make and their corresponding odds. 

Why this bonus is better than others

This bonus is better than others because it requires very little risk to earn a solid reward. Just slap down a $5 bet, and you'll earn the $150 in bonus bets, win or lose.

Why this bonus is better than others

Types of Colorado betting sign-up offers and bonuses

Colorado is one of the few states where three operators do not offer new players sign-up offers or bonuses. BetMonarch, Circa Sports, and Sky Ute have an uphill climb to compete with FanDuel, DraftKings, and others, with loyalty rewards as their most player-friendly promotions. As for the other online sportsbooks, the three most common sign-up bonuses are bet bonuses and first bet insurance.

Deposit match bonus

The deposit match bonus is the most attractive of all sign-up offers because new players earn bonus funds no matter if their first bet wins, loses, or even if they bet at all.

For example, a 100% deposit match up to $500 would mean a new player who deposits $500 would earn a $500 bonus for $1,000 in available funds in their account wallet. A 50% deposit match up to $1,000 would mean a $2,000 deposit would earn $1,000 bonus funds for $3,000 to start. This bonus is the most satisfying of all sign-up bonuses, but becoming more challenging to find as more operators enter the market.

Bonus bets

Some industry leaders, like DraftKings and FanDuel, prefer bet bonuses over a deposit match or first bet insurance. In these scenarios, new players must make a minimum deposit — typically around $10 — and sometimes make a small first wager to unlock the bonus bet funds. Sometimes these bonus bets will be chopped up into increments of, for example, eight (8) $25 bets on a $200 bet bonus, or, in other cases, you can use the entire value of the bonus bets on a single future wager.

For example, if operator X offered a bet bonus of $200, the new player may first be required to deposit $10 and then make a $5 first-time wager. After that initial bet clears, the $200 will be credited to your account. You could risk the $200 on any future bet as the new player. Remember that terms and conditions, and playthrough requirements, may apply before you can request a payout.

First bet insurance

First bet insurance is becoming more common as operators look for new ways to entice new players to sign-up. The bottom line is that to earn any welcome bonus monies, your first bet has to lose. However, this also means you can be more aggressive in your first bet than you would if there was no safety net insurance.

For example, Caesars often offers first-bet insurance up to $1,000. So, if you wager $1,000 on your first bet and it wins, you get a significant boost to your bankroll. Conversely, Caesars will credit your account with $1,000 in bonus bets if your first bet loses. Just remember that bonus bets from first-bet insurance deals expire quickly and can't be withdrawn as cash. 

Referral bonus

Beyond the welcome bonuses, sportsbooks will often offer extra promotions on a regular basis. One of the more common types is a referral bonus, where you can earn an extra perk, like a small bonus bet or some cashback, by getting your friends to sign-up to the sportsbook too.

You'll get a unique code or referral link. If someone uses that referral info to register a new account and make a real money deposit, you'll be rewarded with some sort of bonus. Discover which platform offers the best sportsbook referral bonus via our complete guide.    

Colorado online sportsbooks

Did you know Colorado offers the most legal online sportsbooks in the United States, with 20 active sports betting sites and apps? Interestingly, when the first batch of operators launched their products in May 2020, state law allowed 33 licenses to be issued. So, 13 more online sportsbooks and sports betting apps can still enter the market in the near future. With so much competition, sports betting site operators often work to create a unique user experience in the state, making the entry point more accessible and welcome bonuses and ongoing promotions the most attractive to new players.
