Underdog Sports MO was one of the first sportsbooks (along with DraftKings) to apply for a sports betting license in Missouri. It came as somewhat of a surprise due to Underdog’s limited sportsbook presence, but it’s an exciting development regardless.

🏟️ Bet Types Available at Underdog Sports Missouri
Understanding the various types of bets is crucial to maximizing your sports betting experience. Underdog Sports Missouri go beyond pick’em to offer traditional sports betting options and innovative features for a comprehensive wagering experience.
✅ Moneyline Bets
This is the most straightforward way to bet — pick the winner of a game or match. The odds determine your payout.
Favorites are shown with negative odds (e.g., -150), meaning you need to bet the negative amount shown to win $100. Underdogs come with positive odds (e.g., +200), offering higher payouts (bettors get the listed number if they successfully bet $100).
✅ Point Spread Bets
Underdog Sports MO will set point spreads by giving or taking away points. If the Chiefs are -6.5, they must win by 7 or more for your bet to cash. If the Cardinals are +3.5, they can either win outright or lose by 3 or fewer and still cover. It’s all about the margin of victory or defeat.
✅ Over/Under (Totals)
Also called totals, this bet type focuses on the combined final score of both teams. Underdog Sports MO sets a number, and you bet whether the actual total will go over or under that line. These bets are great for those who have a feel for the pace of play and scoring trends and come without the pressure of picking a winner.
✅ Prop Bets
Prop (proposition) bets let you wager on specific events within a game, often unrelated to the final score. Examples include:
- Will Travis Kelce score a touchdown?
- How many strikeouts will Noah Cameron record?
- Will there be a safety in the Kansas City game?
We expect props at Underdog Sports Missouri to be especially popular in primetime games and playoffs, offering a fun, personalized betting experience.
✅ Parlay Bets
Parlays combine two or more bets into one ticket. All bets (or “legs”) must win for the parlay to cash, but the potential payout increases with each added leg. It’s a high-risk, high-reward play at Underdog Sports Missouri.
✅ Futures Bets
Futures are long-term bets on outcomes that won’t be decided for weeks or months. Likely examples at Underdog Sports Missouri include:
- Who will win the Super Bowl?
- Will the Blues make the playoffs?
- Which player will win MVP?
These bets can offer great value early in the season but require patience.
✅ Live Bets (In-Game Betting)
Live betting lets you wager as the action unfolds. Odds update in real-time based on what’s happening in the game — like a sudden score, injury, or momentum shift.
Underdog Sports Missouri users will be able to bet on things like the next team to score, updated spreads, drive outcomes, or quarter-by-quarter totals. It’s fast-paced and perfect for fans who like to react to the flow of the game.

- St. Louis City SC (MLS): This new MLS club’s fast-paced style and intense home-field advantage make them a fun team to follow in the betting markets, especially for goal totals and halftime/full-time bets.
- Kansas City Current (NWSL): This rising team in women’s soccer is gaining momentum both on and off the field. With national stars and increasing visibility, expect to see more prop markets, player odds, and NWSL futures as the league continues to grow.
- Missouri Tigers (NCAA): Representing the University of Missouri in the SEC, the Tigers compete at a high level in both football and basketball. During college football and March Madness seasons, Mizzou games attract tons of action — from point spreads to player props to season-long futures.
