Sportsbooks launching in Missouri
As shown in the table above, nine sportsbooks have already been approved by state regulators and are expected to launch in Missouri on December 1, 2025. This section will cover those sportsbooks in further detail and give additional information about the promotions they offer new customers in other states.
DraftKings Missouri
The King of Sportsbooks will be in Missouri on Day 1. DraftKings was one of two sportsbooks to be granted a stand-alone license by state regulators and is sure to be one of the most popular sportsbooks in the state.
Right now, DraftKings offers new users $300 in bonus bets after wagering $5 or more on any event. The only catch is that the first bet needs to be a winner (minimum -500 odds) to unlock the bet credits.
Underdog Sportsbook Missouri
Underdog is a very popular DFS site that has recently expanded into the world of traditional sports betting. Underdog Sportsbook is currently available in North Carolina and will be making Missouri its second state of operation when it launches on December 1.
Underdog Sportsbook offers new users up to $1,000 in bonus funds as part of their deposit match promotion. This is one of the best new customer offers in the industry. We are hopeful they will introduce this great promotion to bettors in Missouri when they launch in the state. This section will be updated when the Underdog Missouri promotion is announced.
BetMGM Sportsbook Missouri
A popular choice in many states, BetMGM partnered with Century Casinos to gain access to the Missouri sportsbook market. Their partnership will include a retail sportsbook at the Century Casino in Cape Girardeau.
BetMGM Missouri offers new customers in other states up to $1,500 paid back in bonus bets if their first bet doesn’t win. It is expected that BetMGM will bring their great new customer offer to Missouri along with some enticing ongoing promotions to keep customers coming back.
FanDuel Sportsbook Missouri
There was never a doubt that the biggest sportsbook in the US would launch in Missouri on Day 1. FanDuel offers all the most popular bet types and has hundreds of wagering options for every high-profile sporting event. Bettors in Missouri, many of whom already use FanDuel in neighboring states, will be very happy to be able to access the app from the comfort of their own home.
FanDuel Sportsbook has a solid new promotion that gives new users in Missouri $400 in bonus bets if their first bet of $5 or more wins. No promo code is required to get this great offer.
Caesars Sportsbook Missouri
Caesars already operates two casinos in Missouri, so it was a no-brainer to bring Caesars Sportsbook to the state. Caesars Sportsbook will also open up a retail location at the company-owned casinos. Because of the brand’s existing presence in the state, we expect Caesars Sportsbook to do quite well in Missouri.
Caesars Sportsbook Missouri offers a unique new customer promotion in other states, and we are excited about the possibility of them bring it to Missouri. Anyone who signs up for an account at Caesars Sportsbook can double their winnings on their first 20 wagers of $1 or more. A promo code for this excellent offer is coming soon.
Fanatics Sportsbook Missouri
Fanatics was well-known as a sports-focused clothing and merchandise brand before they decided to expand into sports betting. Things have gone well so far, with the sportsbook app receiving positive reviews in the states where it is available. Fanatics partnered with Boyd Gaming to receive a Missouri sportsbook license. That partnership will also include a retail sportsbook at the two Boyd Gaming casinos in the state.
Up to $300 in bonus bets after wagering $30 or more (hopefully) awaits new customers who sign up for a Fanatics Sportsbook account. No promo code is needed to get this great offer.
bet365 Sportsbook Missouri
The biggest sportsbook in the world has taken America by storm, landing in over a dozen states and becoming quite popular in the process. Bet365 has an easy-to-use app, offers more wagering options on lesser-known sports than the competition, and includes a ton of banking options.
Additionally, those who sign up at bet365 Sportsbook Missouri and bet $5 or more can get $200 in bonus bets, win or lose. What a deal! No promo code is needed to take advantage of this great new customer offer.
theScore Bet Missouri
PENN Entertainment owns two casinos in Missouri, which will allow the company to launch theScore Bet in the state. Bettors may vaguely recall theScore Bet, which is very popular in Canada and operated in a few US states before shutting down when PENN Entertainment decided to rebrand its sportsbook as ESPN BET. That partnership didn’t work out, and now theScore Bet is set to return on December 1, which is also launch day in Missouri.
We aren’t sure exactly what the new customer will be when theScore Bet launches in Missouri in elsewhere because they haven’t made any announcements yet. This section will be updated when we learn how new users will be rewarded for joining theScore Bet.
How to claim Missouri sportsbook promos
Signing up for an account to take advantage of the many pre-registration new customer offers is simple and easy. In just a few minutes, you can be signed up and ready to start wagering on December 1 with some bonus funds in your account. Every sportsbook is different, but they all generally require the steps listed below to create an account.
- Download the sportsbook app or navigate to the home page. There is usually a signup button in the top right corner of the home page, but a few sportsbooks are app-only so you can begin the signup process right when you open the app.
- Enter email address and/or phone number. This is usually the first step and is necessary to create a username and password for logging into the app or website. A confirmation email or text message is sent to confirm your information.
- Enter additional personal information. State regulations require sportsbooks to confirm the identity of each new customer, which is why they need your information. Be prepared to enter your address, phone number, last 4 digits of your SSN, and more depending on the sportsbook. All your information is kept secure using industry-leading security technology.
- Enter promo code. If a promo code is required to get the sportsbook’s new customer offer, it can be entered at this time.
- Finalize registration and make a deposit. The last step is the most important one. It’s time to add some funds to your account. Some sportsbooks have over a dozen deposit options ranging from credit cards to cash at the casino cage to Apple Pay. You are sure to find a deposit option that suits your needs at any of the nine sportsbooks coming to Missouri. Remember that not every deposit option is also available for withdrawal.
- Place your bets! Now comes the fun part. Find a bet you want to make and place it. Before you do that, remember that many promotions are tied to your first actual wager, so be sure to bet enough to qualify you for the offer(s). It would be a bummer to not be able to take advantage of the great offers available for new players in Missouri.
Types of MO sportsbook promos
As mentioned, each sportsbook has a unique promotion to entice new customers to try out their product. These promotions offer different amounts of actual value, however. Some are straightforward while others are on the gimmicky side. Luckily for those in Missouri, the nine sportsbooks coming to the state on December 1, 2025, are among the best in the business and offer legitimately solid promotions. Here is some pros and cons of each promotion type that will likely be available in Missouri.
Bet-Get
If you bet a small amount, usually just $5, you can get a few hundred bucks in bonus bet credits. That’s great, but some of the sportsbooks (DraftKings and FanDuel) require you to win the first bet to unlock the bonus credits, so be sure to find a bet you think has a good chance of winning before making your first wager.
Deposit Match
Make a deposit, and the sportsbook will match it up to a certain amount. Sounds great, but there are always catches to this promotion. Sometimes the match is a percentage, so a larger deposit is required to get the full offer. Sometimes, there is a playthrough requirement that requires additional wagering in order to withdraw any winnings. And the credits always expire after a week or two, which means there is no time to waste. All that said, deposit match promotions are some of the best offers out there, so we encourage you to take advantage of them.
First Bet Refund
Also known as a second-chance bet, this promotion gives new users a second chance if their first bet comes up short. First bets that don’t win are refunded up to a certain amount in the form of bonus bet credits. Just remember that the second bet is not refunded, so if you lose twice in a row, you’re out of luck.
Odds Boost
This one takes many different forms, but the bottom line is that a new user’s winning wager can receive an additional boost. Caesars has a popular odds boost promotion that doubles the payout (boosting the odds by 100%) on a new customer’s first 20 bets. Odds boosts are also common promotions for existing customers and are often connected to a featured bet, usually a parlay.
Conclusion
All of the top sportsbooks in the country have been approved to open up shop in Missouri. This is great news for bettors in the state, many of whom have had to go across the border to neighboring states to wager on their favorite sports teams legally. Some sportsbooks are offering pre-registration specials before the December 1 launch date. We recommend you sign up for as many sportsbook offers as possible to start your sports betting journey with hundreds of dollars in bet credits ready to use on Day 1.
