We've highlighted the top sportsbook operators for Missouri bettors, but the Show Me State also has several other solid online gambling sites that have entered the market.

Our additional review has highlighted more lucrative Missouri sports betting promos that new users can take advantage of. 

bet365 MO welcome bonus

bet365 has a great reputation as a respected online gambling site, dating back to its early days as a leader in the U.K. gambling space. It's now brought over its best-in-class odds to Missouri online sports betting, which will be the 16th state that bet365 has launched in over the United States.

The platform is a favorite among seasoned bettors for its strong pricing and extensive player prop menus across the NFL, NBA, and NHL. It also excels for odds pricing in niche sports like MMA, where it ranks as one of our top UFC betting sites.

For its Missouri launch, bet365 has a great welcome bonus, a 'bet $5, get $150 in bonus bets (win or lose)' offer that is extremely simple to claim, by observing the following terms and conditions. There is also a secondary offer you can claim instead, a $1,000 First Bet Safety Net. 

• Download the bet365 Missouri app and register for an account.
• Deposit $5 or more using one of the verified deposit methods.
• Make any wager of $5 or more, with at least -500 odds or longer.
• Win or lose, you'll be credited with $150 in Bonus Bets.
• Bonus bets cannot be cashed out and expire after seven days.
• Alternatively, claim the secondary offer, a $1,000 First Bet Safety Net, where you're first bet will be refunded up to $1,000 in bonus bets.

Also, watch out for more ongoing promotions from bet365 for current Missouri bettors. bet365 has a great list of ongoing promos, like Early Payout, which pays out certain moneyline bets early if your team goes up by a certain amount, and applies even if they lose the game. A snapshot of how it works by sport can be found below:

NFL: When a team leads by 17+ points

NBA: When a team leads by 20+ points

Soccer: When a team leads by 2+ goals

This is one of the user-friendly features of the site and continuously gets brought up in positive bet365 app reviews.

theScore Bet MO welcome bonus

theScore Bet sportsbook is already live in several U.S. states and in Ontario, Canada. The app delivers a unique experience by integrating with theScore Sports News & Scores, a media app covering major sporting leagues. 

Although theScore Bet is a new name in the MO sports betting arena, it's essentially just the rebranded version of ESPN BET following the collapse of the partnership between PENN Entertainment and ESPN.

A lot of great features from ESPN BET were carried over to the current version of theScore, and they've delivered a solid Missouri welcome bonus: 'Bet $10, Get $100 in Bonus Bets if you win', the details of which are below. 

• Register for a new theScore Bet account.
• Deposit $10 or more into your theScore Bet account.
• Make bets worth $10 or more (cumulative) on any market.
• There are no odds restrictions on your initial wagers.
• If your bets wins, you'll receive $100 in Bonus Bets.
• Your bonus bets will be sent to you as five $20 tokens.
• Bonus bets cannot be withdrawn as cash and have a seven day expiry.

Missouri residents can now access legal online betting as of Dec. 1, 2025, including the best World Cup betting sites.

However, one thing to note in the Missouri sports betting landscape is the status of college prop bets. Missouri has chosen to restrict college prop bets such that bettors cannot wager on player props in games involving athletes at Missouri colleges or universities. 

We've broken down the rest of the key points about sports betting in Missouri below. 

Getting started with Missouri sports betting promos is simple. This guide helps you unlock top Missouri sportsbook promos and ensures a safe, easy entry into this new online betting market.

1. Pick a sportsbook promo

Missouri sportsbooks offer a range of new customer deals, including bonus bets, deposit boosts, and odds enhancements. Browse the top offers listed here and select the one that best matches your betting goals.

2. Claim your promo code

Click one of the trusted links on this page to get started. Some sportsbooks automatically apply the bonus, while others require a code during sign-up. You may also need to download the Missouri mobile sports betting app to complete registration.

3. Create a new account

Fill out the sign-up form with details like your full name, date of birth, residential address, email, and the last four digits of your Social Security number. These details confirm your eligibility to place bets in Missouri.

4. Verify your identity

Upload a valid photo ID to confirm you’re at least 21 years old and physically located within Missouri, as required under state regulations.

5. Deposit funds

Make a qualifying deposit to activate your Missouri betting promos. Options include debit cards, credit cards, PayPal, Venmo, online banking, and digital wallets like Apple Pay.

6. Place a bet

With funds in your account, place your initial wager. Review any specific requirements, such as minimum odds, qualifying bet amounts, or eligible sports, to ensure the bonus is triggered.

7. Enjoy your bonus

Once your bet settles, you receive your bonus credits or bet tokens. These are often time-sensitive, typically expiring within seven days, so be sure to use them while they’re still active.

Once you've claimed one of the Missouri sportsbook promos, it's time to put those bonuses to work. Ideally, we want to maximize these offers and ensure we walk away with even more profit once we've met the play-through requirements or any other terms & conditions. 

Here are some subtle, but powerful tips you can use to ensure you're getting the best value from your Missouri sportsbook bonuses. 

✍ Pay attention to bonus terms

This is crucial to maximizing your Missouri sportsbook bonus. Almost every sportsbook has different expiration dates, requirements, odds restrictions, and wagering requirements for welcome bonuses. For example, DraftKings bonus bets expire after seven days. Always check the terms and conditions before signing up. 

📈 Spread your risk

While going all in on one big bet is always tempting, approaching your bonus offers as an investment will ensure greater long-term profit. We recommend keeping risk small and targeting odds between -200 to +200. This way, you can mitigate your risk and reduce short-term variance. 

💡Bet what you know

In addition to not going all-in on a single bet, you should also attempt to avoid the unknown by only wagering on markets you're familiar with or have a proven track record in. By keeping your focus narrow, you can highlight more profitable opportunities and increase your chances of coming out ahead. 

🔎 Look for more opportunities

In addition to welcome bonuses, Missouri sportsbooks will offer a wide range of ongoing promos for existing users, such as profit boosts or same-game parlay insurance. Keep checking the sportsbooks' ongoing offer pages to stay informed about more opportunities to maximize value. 

There is now a wide range of sign-up bonuses available to new users, with wagering open. The most common bonuses available to Missouri bettors are 'bet and get' promotions that provide bonus bets for an initial wager. There are also the 'second-chance' wagers, which act as a sort of safety net for your first bet on the site. Some of the bet and get promotions, but not all, will also provide guaranteed bonuses, which means you can take a long shot on your first wager without much worry. 

The bottom line is that major operators are competing to attract new players, and these bonuses are designed to give bettors a strong start and make the sign-up process even more rewarding. As a result, we've broken down all types of promos for you, and after reading, we're confident you'll come out with a better sense of what to expect when reading each bonus's wager requirements and conditions. 

💰 Bet and get

A 'bet and get' bonus is one of the simplest and most popular promotions among sportsbooks. You place a small qualifying wager, usually around $5 or $10, and receive bonus bets in return. Many bet and get promotions come with no risk, meaning you receive your bonus bets even if you lose your initial wager; however, it's important to check the terms before betting. Either way, these make for an easy way for new bettors to test out an online betting site, without much risk.

🎯 Second chance bet

Second-chance bets refund your stake if your opening wager loses. For example, if you bet $200 on the Kansas City Chiefs moneyline and the Chiefs lose the game, the sportsbook will credit your account with $200 in bonus bets. If your bet wins, you just collect your payout.

💵 Deposit match

A deposit match bonus rewards players who start with a bigger bankroll. When you make your first deposit, the sportsbook matches it with bonus funds, often up to a certain limit. For example, a $250 deposit could earn you an additional $250 in site credit to use for betting.

🎁 No deposit bonus

Though less common, a no-deposit bonus is a favorite among bettors because it gives you free site credit or bonus bets just for signing up, no deposit required. These limited-time promotions often appear on Super Bowl betting sites and during other major events, such as the NBA Finals or Stanley Cup Finals, so keep an eye out for them.

On the board: Missouri’s football calendar is led by two rivalry games this week. Missouri visits Kansas on Friday for the latest meeting in the Border War, while the Chiefs open their NFL season Monday at Arrowhead Stadium against the Broncos, the team that ended Kansas City’s nine-year run atop the AFC West last season. The wider NFL schedule begins Wednesday with Patriots-Seahawks and continues Thursday with 49ers-Rams in Australia before Sunday’s full slate.

Baseball remains busy as the Royals finish their home series against Arizona on Wednesday before visiting Boston from Friday through Sunday, while the Cardinals wrap up their trip to San Francisco and return to St. Louis for a weekend series against the White Sox. The US Open crowns its women’s singles champion Saturday and men’s champion Sunday, while Saturday’s combat-sports card features Noche UFC: Jean Silva vs. Jose Miguel Delgado.

Boosts to know about: bet365’s NFL Early Payout settles an eligible pregame moneyline straight bet as a winner if the backed team takes a 17-point lead at any stage. For qualifying parlays and same-game parlays, that team’s selection is marked as a winner while the remaining legs continue. BetMGM’s BetDefense provides another football-specific option for eligible NFL player props. If the selected player leaves because of injury during the first quarter, before the bet has settled, and is officially ruled out for the remainder of the game, qualifying straight bets are canceled with the stake returned, while affected parlay or SGP legs are canceled and the rest of the ticket remains active.

Weekly Spotlight: Integrate your sports bets and news with theScore

theScore Bet connects directly with theScore sports media app, giving Missouri bettors a way to follow games and manage their wagers from the same ecosystem. Its dedicated Bet Section surfaces betting markets based on a user’s favorite teams and leagues and automatically tracks wagers placed through theScore Bet, including real-time cash-out offers when available.

The integration also includes personalized promotions and community polls around current betting lines, while a shared login links theScore and theScore Bet accounts. With NFL Week 1 underway and the Chiefs opening Monday against Denver, Missouri bettors can follow games through theScore and move between scores, stats, markets, and active bets without managing two separate experiences.

Missouri is home to some of the most passionate sports fans in the nation. While we always caution against letting your hometown bias cloud your judgment when placing bets and wagers on your favorite teams and players, it can be extra rewarding when backed by thorough research.

Here are the most popular teams to bet on in the Show-Me State:

🏈 Kansas City Chiefs 

After a disappointing 2025 season, the four-time Super Bowl champion Kansas City Chiefs will look to get back on track in 2026. With future Hall of Famer Patrick Mahomes still in the prime of his career, the Chiefs will look to dethrone the defending AFC West champion Denver Broncos.

⚾ St. Louis Cardinals 

Perennial National League Central contenders, the St. Louis Cardinals are a team steeped in tradition and one of the most storied franchises in MLB history. The Cards are seeking their 12th World Series title as they try and earn a postseason spot.

⚾ Kansas City Royals

🏒 St. Louis Blues 

The St. Louis Blues are looking to return to the playoffs after missing out on the postseason during the 2025-26 season. With a roster that includes veterans Robert Thomas and Colton Parayko and youngsters Jimmy Snuggerud, Logan Mailloux and the newly acquired Mason McTavish, the Blues have their eyes set on a bounce-back season.

⚽ St. Louis CITY SC

Established in 2019, St. Louis CITY SC made its Major League Soccer (MLS) debut in 2023. Led by striker João Klauss, the club will look to return to the playoffs for the second time in team history in 2026.
