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 six favorite sportsbooks in the state, including more details about the value of the sign-up offers.

1. FanDuel CO welcome offer 🔵

Win $150 + NBA League Pass 🏀

New customers only. Deposit min. $5. Place first bet of $5+ and win $150 in Bonus Bets (within 72 hours).

Each product featured on our website has been meticulously researched and selected by our team of experts. If you sign up through our links, we may get a commission. 21+ and present in CO. Gambling Problem? Call 1-800-522-4700.

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 places 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 $5 is required.
  • Make an initial wager of $5 or more. If it wins, FanDuel will credit your account with $150 in bonus bets.
  • Bonus bets will hit your account within 72 hours of your first wager settling.
  • Bonus bets must be used within seven days.
ProsCons
✅ Low initial risk required❌ Quick expiry
✅ Bonus can be split into multiple bets❌ Available in the app only
✅ Low min. deposit requirement❌ First bet must win

Why this FanDuel bonus is better than others

Although other CO sportsbooks offer similar (or even identical) deals, FanDuel's welcome bonus is still extremely great value. Getting $150 in super-flexible bonus bets in exchange for a $5 risk is easily one of the best deals I've ever come across, even though your best must win in order to collect.

2. DraftKings CO welcome offer 👑

Bet $5, Get $150 + $1K Deposit Bonus

Terms and conditions apply.

DraftKings’ current welcome bonus is perfect for newbies. No DraftKings promo code is required to get in on the bet $5, get $150 in bonus bets welcome offer. DraftKings also sports some of the top super boosts out of any sportsbook, just in time for the major events like the the NFL season or World Series.

  • You must deposit and place a qualifying wager of $5 or more on any sport
  • You'll get the $150 reward instantly
  • The bonus funds will come in six (6) $25 increments to be used on future wagers
  • Bonus funds must be used within seven days

DraftKings also 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. 

ProsCons
✅ No promo code required❌ Smaller maximum value
✅ Only a $5 initial wager needed❌ Seven days to use bonus
✅ Good for new players
✅ Easy to read terms and conditions

Why this DraftKings bonus is better than others

Unlike some other welcome offers, DraftKings’ bonus is a 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. And, whether or not they happen to win, they'll get $150 in bonus bets to further wager with the sportsbook.

BetMGM Android App
ProsCons
✅ Low minimum deposit❌ Bet has to lose
✅ Large bonus bet total❌ Bonus bets expire in a week
✅ Only have to risk $10 bet

Why this BetMGM bonus is better than others

BetMGM offers $1,500 in bonus bets, which you can claim simply for making any $10 wager. While your bet has to lose to claim the First Bet Offer token, it's a good way to place a big wager without worrying about losing your money. 

4. Caesars CO welcome offer 🏛

Bet $1, Get 10x 100% Profit Boosts

New users only. Must use promo code. Min. $10 deposit. Max. additional winnings $2.5K per token. Tokens expire in 14 days. Void where prohibited. Full terms.

Each product featured on our website has been meticulously researched and selected by our team of experts. If you sign up through our links, we may get a commission. 21+ and present in CO. Gambling Problem? Call 1-800-522-4700.

Caesars doesn't change their offer very often, but that's not a problem since they have one of the best deals in the industry. New users are welcomed with a bet $1, get 10 100% Proft 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

  7. Profit Boosts will expire after 14 days
ProsCons
✅ High-value bonus❌ First bet must lose
✅ No odds or market restrictions ❌ Quick expiry date
✅ Great for veteran bettors❌ Can’t withdraw as cash

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.

5. Fanatics CO welcome offer 🧢

Get up to $1,000 in No Sweat Bets

Terms and conditions apply.

Each product featured on our website has been meticulously researched and selected by our team of experts. If you sign up through our links, we may get a commission. 21+ and present in CO. Gambling Problem? Call 1-800-522-4700.

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 will receive ten daily No Sweat Bet opportunities up to $1,000 in total, and no Fanatics Sportsbook promo code is required.

  • Minimum $1 daily wager requirement.
  • Bonus bets only paid out if your first daily bet loses, up to $100 per day.
  • Daily qualifying wager must have -500 odds or longer.
  • No opt-in is required on day one, but you must opt-in before wagering on each of the following days.
  • Missing a day loses your bonus opportunity for the day.
  • Bonuses expire after seven days.
ProsCons
✅ Ten separate bonus chances❌ Daily opt-in required
✅ Gain up to $1,000 in bonuses❌ Bonuses expire quickly
✅ $1 minimum wagers❌ Bets must lose to claim bonus

Why this Fanatics bonus is better than others

Few sportsbooks offer welcome bonuses reaching $1,000, and Fanatics checks that box. While the process to claim the maximum bonus amount is a bit tedious (and would require a prolonged losing streak), there are also benefits to spreading your qualifying wagers out over a ten-day span.

6. BetRivers CO welcome offer ⚡

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 won't need a BetRivers bonus code at any time.

  • 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.
  • Odds restrictions do apply when using bonus funds.
  • 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 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.

More sportbook promo codes

We've covered our top six CO sportsbook promos in-depth, but there are a few others still worth your time. Check out any of these options for further bonus opportunities:

The bet365 bonus code unlocks additional rewards after your first wager and is an excellent choice with great bonuses all year. You can claim $150 in bonus bets OR up to $1,000 in first bet insurance. You can only claim the bet365 welcome bonus in the mobile app.

The ESPN BET promo code works a little differently, with up to $1,500 in bonuses + a 200% first deposit match ($500 max.) available to new users.

Tipico is also a good choice, with a straightforward welcome bonus. Use our Tipico promo code to get $200 in bonus bets when you deposit $50.

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. We want everyone to do their due diligence and make an educated decision before signing up with a new online sportsbook, and the quality of the sites’ and apps’ promotions is a big part of the puzzle. Some areas we concentrate our attention on are:

  • 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 insurance?
  • 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 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 leading sportsbooks prefer bonus bets 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. 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 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 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.
