With more than a dozen options and licenses to spare, each sports betting site is jockeying for market share in the Rocky Mountain State. Of the 15, only three require bettors to enter a promo code: BetMGM, BetRivers, and Caesars.

After signing up, existing users can also take advantage of offers tied to major sporting events, with many operators offering March Madness betting promos during the tournament.

Here's a breakdown of my six favorite sportsbook promos in the state, including details about the value of each signup offer.

1. Why Fanatics has the best Colorado sportsbook promo 🧢

Fanatics is relatively new in the sports betting industry, but its welcome offer goes toe-to-toe with the more established brands. First-time customers get a great sign-up bonus: Up to $1,000 in FanCash Bet Matches. No Fanatics Sportsbook promo code is required.

This offer requires a daily wager of $1 or more at odds of -200 or longer. Win or lose, Fanatics will issue FanCash in the amount of your wager, up to $100 every day.

Here are the details:

• Register a new account with Fanatics Sportsbook (mobile app only).
• Deposit at least $10 into your account.
• Make a daily qualifying bet of $1 or more, with minimum odds of -200 or longer.
• Fanatics will match the entire stake as FanCash, up to $100.
• Repeat this process for the first ten days after creating your account (10 x up to $100 per day).
• Opt-in required on every day except Day One.
• Missed days are forfeited, but you can still earn the bonus on any remaining days.
• FanCash cannot be withdrawn as cash and expires after seven days.

There's also a secondary offer available in Colorado, which allows new users to bet $20 and get $200 in bonus bets instantly.

Why this Fanatics bonus is better than others

The Fanatics bonus is perfect for any bankroll, since it scales up (or down) to your betting budget. While higher rollers might have no issues betting $100 multiple days in a row, novice bettors can still participate so long as they bet a minimum of $1 per day. 

2. BetMGM CO welcome bonus 🦁

BetMGM offers an enticing welcome bonus in Colorado. New players can earn a First Bet Offer up to $1,500 + $50 in BetMGM Rewards Points. The BetMGM bonus code SBRMGM is required for this bonus.

• Register a new BetMGM account with the code SBRMGM.
• A minimum first-time deposit of $10+ is required.
• If your first bet loses, BetMGM will refund your entire stake via bonus bets (up to $1,500).
• BetMGM will issue bonus bets in 20% increments for first bets of $50 or more.
• A single bonus bet credit is awarded for first bets of $49 or less.
• Win or lose, you'll be credited with a $50 BetMGM Rewards Points bonus.
• Bonus bets must be redeemed within seven days of receiving them.

Why this BetMGM bonus is better than others

BetMGM offers a $1,500 first bet offer, which you can claim simply by making any wager. While your bet has to lose to claim this bonus, it's a good way to place a bigger wager, knowing you'll get bonus bets back if you lose.

3. bet365 CO welcome bonus 🟢

bet365 was founded over 20 years ago in the United Kingdom and is among the world’s most popular and well-respected international online sportsbooks.

Colorado betting promos don’t get much better than this for sports fans looking for an inexpensive entry point. When you make your first deposit and wager of $10 or more, your account will be awarded $200 in bonus bets regardless of whether your initial bet wins or loses. You won't need to use a bet365 bonus code to claim this offer. Just use our exclusive link to get started. 

bet365 also has a second welcome promo option if you prefer — a $1,000 First Bet Safety Net. Place your initial wager of any amount on any sports market, and should you lose, bet365 will return your stake, up to $1,000 in bonus bets. You can only claim the bet365 welcome bonus in the mobile app.

Why this bonus is better than others

There is no real downside to this Colorado sportsbook bonus. All you have to do is bet $10 and you'll unlock $200 in bonus bets. You get these bonus bets whether you win or lose your initial bet. And best of all, there is no price cap on what you can use your bonus bets on. We recommend looking for odds of +100 or greater because if you win a bonus bet, you'll only be awarded the winnings and not what you stake. 

Odds correct at time of publishing.

4. FanDuel CO welcome bonus 🔵

One of the best online sportsbooks in Colorado has a great welcome bonus for new players. FanDuel offers a bet $5 and get $150 in Bonus Bets if you win reward for anyone who places a qualifying wager on any available betting market. No FanDuel promo code is required.

• Available via the FanDuel app only.
• Minimum deposit of $5 is required.
• Make an initial wager of $5 or more. FanDuel will credit your account with $150 in Bonus Bets if your bet wins.
• Bonus bets will hit your account within 72 hours of your first wager settling.
• Bonus bets must be used within seven days.

Why this FanDuel bonus is better than others

Although other CO sportsbooks offer similar (or even identical) deals, FanDuel's welcome bonus remains a great value. Getting super-flexible bonus bets in exchange for a $5 risk is a great deal (assuming your bet wins).

5. DraftKings CO welcome bonus 👑

DraftKings’ current welcome bonus is perfect for newbies. No DraftKings promo code is required to get in on the bet $5 or more and get $100 in bonus bets instantly welcome offer. 

• You must deposit and place a qualifying wager of $5 or more on any sport, min -500 odds
• You'll get the $100 reward instantly, whether or not your first bet is a winner.
• The bonus funds will come in Four (4) x $25 Bonus Bets to be used on future wagers
• Bonus funds must be used within seven days

Additionally, DraftKings has a secondary promo available on top of its main welcome offer. You can claim a 20% deposit bonus, up to $1,000, by opting in via the DraftKings promotions page. The downside is the bonus funds come with a hefty playthrough requirement before you can withdraw them as cash. 

Why this DraftKings bonus is better than others

Unlike some other welcome offers, DraftKings’ bonus is a relatively low-risk play. Staking a mere $5 allows new users to give the platform a try and decide if they want to stay long-term.

6. Caesars CO welcome offer 🏛

Caesars has started changing its offers more frequently, but that's not a problem since it has one of the best deals in the industry right now. New users are welcomed with a bet $1, and get ten 100% Profit Boost Tokens offer. You must use the Caesars Sportsbook promo code SBRBONUSDYW when registering. Here is how to take advantage of the promo:

1. Create a new account and register with promo code SBRBONUSDYW.
2. Make an initial minimum deposit of at least $10.
3. Make an initial wager of $1 or more.
4. After placing your first wager, you'll receive Ten (10) 100% Profit Boost Tokens to use on any market.
5. The max wager for each rewarded Profit Boost is $25.
6. The max additional winnings for each rewarded Profit Boost is $2,500.
7. Profit Boosts will expire after 14 days.

Why this Caesars bonus is better than others

Caesars has plenty of options for veteran and novice sports bettors, and it has one of the best loyalty rewards programs in the business. This welcome offer is a no-brainer for new Colorado bettors. 

7. BetRivers CO welcome bonus ⚡

BetRivers has shifted its welcome bonus a little in recent months. Rush Street Interactive’s top-rated sportsbook offers a second chance bet of up to $250, and bettors can use our BetRivers bonus code SBRBONUS to claim it. 

• Minimum deposit of $10 is required.
• First bet must lose to earn First Bet Offer.
• Bonus funds will be added to your account within a day.
• Odds restrictions do apply when using bonus funds.
• Bonus must be wagered on events with odds of -200 or longer.

Why this BetRivers bonus is better than others

The terms on this BetRivers bonus are similar to BetMGM's, except the maximum bonus total is lower. Still, the majority of bettors aren't likely to be making $1,500 bets right out of the gate, which means BetRivers' $250 Second Chance Bet is still perfectly aligned with most bankrolls.

How we rate and review sports betting promotions

Our editorial team independently reviews and rates each Colorado online sportsbook and sports betting app for quality, safety, and user experience. Our experts apply the same rigorous evaluation when critiquing the sports betting promotions operators offer new and veteran players. Here are some areas we concentrate our attention on:

• The sign up offers minimum and maximum value.
• Is a minimum deposit required to earn the bonus? If yes, how much?
• Is the welcome bonus guaranteed?
• What kind of bonus is being offered: Deposit match, bonus bet, or First Bet Offer?
• Is a promo code required to activate the offer?
• What are the playthrough requirements or terms and conditions needed to collect the offer?
• Does the welcome bonus have an expiration date, and how long is it?

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 Offer.

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 leading sportsbooks prefer bonus bets over a deposit match or First Bet Offer. 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. In other cases, you can use the entire value of the bonus bets on a single future wager.

For example, if a sportsbook 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 offer

First bet offer 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, BetMGM often offers a First Bet Offer up to $1,500. So, if you wager $1,000 on your first bet and it wins, you get a significant boost to your bankroll. Conversely, BetMGM will credit your account with $1,000 in bonus bets if your first bet loses. Remember that bonus bets obtained from First Bet Offer 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 15 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, 18 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.

Here are all 15 Colorado sports betting apps you can use:
