All Colorado sportsbook promo codes and bonuses

Colorado’s interest in legal online sports betting is clear with 19 active operators competing for market share in the state. Out of these, only five – bet365, BetMGM, BetRivers, Caesars, and SuperBook – require bettors to enter a promo code when making their first deposit.

Some operators, such as Betsafe and Tipico, offer a deposit match bonus, which is a less common type of welcome bonus compared to first-bet insurance or bonus bets.

How much money can be earned with the promo?

The amount of money you can earn through this promotion is based on how successful you are as a bettor. If you win your qualifying bet and subsequent bets using the bonus funds provided, you can make a significant amount of money immediately.

Why this bonus is better than others

DraftKings offers a low-risk welcome bonus that allows new users to try out the platform by staking just $5. Regardless of the outcome, users will receive $150 in bonus bets to use on the sportsbook. This provides a great opportunity for users to decide if they want to continue using DraftKings long-term.

The bonus bets must be used within 7 days. This offer is valid for new customers only and is subject to additional terms and conditions.

Underscoreg Review may receive advertising commissions for visits to a sportsbook or casino betting site. 21+ and present in CO. Gambling Problem? Call 1-800-522-4700.

New players at BetMGM can take advantage of a four-figure first-bet insurance as their welcome offer. Dubbed the “King of Parlays,” BetMGM will cover your first bet up to $1,500 in case it doesn’t win. Simply use the BetMGM bonus code SBRBONUS when making your first deposit to claim this offer.

  • Minimum deposit of $10.
  • Your first bet must lose to earn welcome bonus insurance funds.
  • If your first bet wins, no bonus monies are received.
  • The $1,500 will be credited within 24 hours of your first bet settling
  • Bonus credits are divided into five equal bonus bets. So, a $1,500 first bet loss would be converted into five (5) $300 bonus bets.
  • If first bet was less than $49, bonus bets will be issued as a single credit.
  • You must use the bonus within seven days.
ProsCons
✅ Low minimum deposit❌ First bet must lost
✅ First bet insurance for new players❌ Bonus bets expire in a week
✅ Highest total dollar value bonus

Why this BetMGM bonus is better than others

It is rare to find a welcome bonus worth $1,500, making BetMGM stand out in terms of total value. For those looking to place a substantial first bet in Colorado, I highly suggest taking advantage of BetMGM’s first-bet insurance offer.

4. BetRivers CO welcome offer ⚡

Up to a $250 Second Chance Bet

Terms and conditions apply.

Recently, BetRivers has made some changes to its welcome bonus. The popular sportsbook from Rush Street Interactive now offers a second chance bet worth up to $250. To take advantage of this offer, bettors must remember to enter the BetRivers bonus code SBRBONUS when making their initial deposit.

  • Minimum deposit of $10 is required.
  • First bet must lose to earn first bet insurance.
  • Bonus funds will be added to your account within a day.

  • Bonus must be wagered on events with odds of -200 or longer.
ProsCons
✅ Low minimum deposit required❌ First bet must lose to earn
✅ Allows first bet to be more aggressive❌ Odds restrictions on the bonus bet
✅ Bonus funds hit quickly

Why this BetRivers bonus is better than others

The BetRivers bonus terms closely resemble those of BetMGM, with the only difference being a lower maximum bonus total. However, most bettors are unlikely to start off with $1,500 bets, making BetRivers’ $250 Second Chance Bet suitable for the majority of bankrolls.

  • Minimum deposit of $10.
  • Make your initial bet within 30 days of opening your account.
  • First bet must lose to unlock first bet insurance.
  • Bonus funds will be credited to your account within 48 hours of the first losing bet settling.

ProsCons

Why this Caesars bonus is better than others

While BetMGM’s first-bet insurance offer may be lower than BetRivers, it still surpasses the latter. Additionally, Caesars includes one of the top loyalty rewards programs in the industry, making this welcome offer an obvious choice for new Colorado bettors.

6. Fanatics CO welcome offer 🧢

Get up to $1,000 in Bonus Bets

Terms and conditions apply.

Underscoreg Review may receive advertising commissions for visits to a sportsbook or casino betting site. 21+ and present in CO. Gambling Problem? Call 1-800-522-4700.

  • Minimum $5 wager requirement.
  • Receive your bonus match payout whether your wagers win or lose.
  • Score up to $200 in bonuses in the first five days following account creation, totaling $1,000 in bonus credits.
  • No opt-in is required on day one, but you must opt-in before wagering on each of the following days.

  • Bonuses expire after seven days.
ProsCons

Why this Fanatics bonus is better than others

Not many sportsbooks provide welcome bonuses as high as $1,000, but Fanatics does. Although the process to get the full bonus amount may be a little complicated, there are advantages to spreading out your bonus match bets over five days.

Types of Colorado betting sign-up offers and bonuses

In Colorado, BetMonarch, Circa Sports, and Sky Ute do not provide new players with sign-up offers or bonuses, making it difficult for them to compete with FanDuel, DraftKings, and other operators. Instead, these three operators focus on loyalty rewards as their most player-friendly promotions. On the other hand, the most common sign-up bonuses offered by other online sportsbooks in the state are bet bonuses and first bet insurance.

Deposit match bonus

The deposit match bonus is the most appealing sign-up offer because new players receive bonus funds regardless of the outcome of their first bet or whether they place a bet at all.

An instance of this would be a 100% deposit match up to $500, where a new player depositing $500 would receive a $500 bonus, totaling $1,000 in their account. Another example is a 50% deposit match up to $1,000, where a $2,000 deposit would earn a $1,000 bonus, resulting in $3,000 to begin with. Although this bonus is the most gratifying among sign-up bonuses, it is becoming harder to come by as the market becomes more crowded with operators.

Bonus bets

Some of the top sportsbooks in the industry prioritize bonus bets over deposit matches or first bet insurance. In order to access the bonus bet funds, new players are usually required to make a minimum deposit of around $10 and sometimes place a small initial wager.

At times, bonus bets may be divided into smaller increments, such as eight (8) $25 bets from a $200 bonus. Alternatively, the full value of the bonus bets can be used for a single future wager in some instances.

If a sportsbook offers a $200 bet bonus to new players, they may need to deposit $10 and place a $5 first-time wager before receiving the bonus. Once the initial bet is settled, the $200 bonus will be added to the player’s account. The bonus can be used on any future bet. Keep in mind that there may be terms and conditions, as well as playthrough requirements, that must be met before requesting a payout.

First bet insurance

More operators are offering first bet insurance to attract new players. In order to receive any welcome bonus funds, your initial bet must be unsuccessful. This allows you to take a more daring approach with your first bet, knowing that there is a safety net in place.

One example is Caesars offering first-bet insurance up to $1,000. If you bet $1,000 on your first bet and win, you receive a substantial increase to your bankroll. However, if your first bet loses, Caesars will credit your account with $1,000 in bonus bets. It is important to note that bonus bets from first-bet insurance promotions have a short expiration date and cannot be withdrawn as cash.

Referral bonus

In addition to welcome bonuses, sportsbooks frequently provide ongoing promotions. One popular type is a referral bonus, which allows you to receive additional benefits such as a bonus bet or cashback by inviting your friends to join the sportsbook.

Find out how to earn a bonus by referring friends to a sportsbook platform through our comprehensive guide. Simply share your unique code or referral link, and if someone signs up and makes a deposit using your information, you’ll receive a reward. Check out our guide to find the platform with the best sportsbook referral bonus.

Colorado online sportsbooks

Colorado has the highest number of legal online sportsbooks in the United States, with 19 currently active sites and apps. It’s worth noting that when the initial operators launched in May 2020, the state had the capacity to issue 33 licenses, leaving room for 14 more online sportsbooks to enter the market. This level of competition has led operators to focus on creating a unique user experience to attract new players, with welcoming bonuses and ongoing promotions being particularly enticing.

Colorado sportsbook promos FAQs

What’s the best sports betting bonus in Colorado?

The concept of “best” is subjective to personal tastes. Nevertheless, we highly recommend considering bet365’s offer of betting $5 and receiving $150 in bonus bets as one of the top options. This deal involves minimal risk, as the outcome of your first bet does not determine your eligibility for the bonus funds.

Which verified Colorado sportsbook promos are the best value?

The most valuable CO sportsbook promotion for you will vary based on your individual betting preferences and financial situation. Some may prefer the security of smaller, guaranteed bonuses, while others may be more interested in trying out a larger first-bet insurance offer.

How old do I need to bet on sports in Colorado?

To place bets on Colorado sports, you need to be at least 21 years old.

Do all Colorado sportsbooks provide sports betting promo codes?

In most cases, promo codes are not needed at online sportsbooks and sports betting apps. Promo codes are often applied automatically when selecting an offer or bonus, making it one less thing to think about. If a promo code is required, you can find the latest verified and accurate codes in the list above.

What are the playthrough requirements on legal online sportsbooks in Colorado?

The playthrough requirements for welcome bonuses and regular promotions differ depending on the online sportsbook. Fortunately, all terms and conditions are now clearly communicated before you decide to take advantage of any bonuses or promotions. Make sure to carefully read and comprehend the T&Cs, including the playthrough requirements, before agreeing to any bonus offers.

How many sign-up bonuses can I claim in Colorado?

You can claim a single sign-up up bonus from every online sportsbook in CO that offers one. Remember that the welcome bonus is a one-time promotion for new customers only.
