Sports betting is finally on its way to Missouri, and Underdog Sportsbook is preparing to join the lineup of operators expected to go live by the state’s December 1, 2025 launch deadline. Already active with a sportsbook in North Carolina and well-known nationwide for its daily fantasy products, Underdog is looking to expand its sportsbook footprint, and Missouri is next in line.
Missouri Sports Betting Timeline

Who’s Coming to Missouri?
According to the latest regulatory filings and industry updates, at least 10 operators have either received, applied for, or announced plans to obtain a Missouri mobile license:
bet365
BetMGM
Caesars
Circa Sports
DraftKings
ESPN BET
Fanatics Sportsbook
FanDuel
Underdog
This puts Missouri on track to be one of the most competitive sports betting markets in the Midwest.
Underdog’s Betting Position
Early Mover: Alongside DraftKings, Underdog was among the very first sportsbooks to file its Missouri application this summer.
License Strategy: With DraftKings and Circa receiving the state’s two untethered licenses, Underdog will be pursuing a tethered partnership with a local casino or pro team.
Second Sportsbook State: If approved, Missouri will mark only the second sportsbook state for Underdog, after its North Carolina debut in March 2024.
Underdog’s leadership has stated they are “aggressively pursuing” sportsbook expansion opportunities, and Missouri is a major step in that plan.
| FanDuel | Bet $5, Get $200 in Bonus Bets (typical offer) | #1 U.S. market leader, top mobile app, wide bet variety | Heavy promotional spend; partnerships with pro teams likely |
| DraftKings | Up to $1,000 Deposit Match + Bet Credits | Strong app, deep markets, DFS integration | Early applicant for MO license; major competitor to FanDuel |
| BetMGM | $1,500 First Bet Insurance | Retail casino partnerships, strong rewards program | Likely to link with MGM properties in Midwest for tethered license |
| Caesars Sportsbook | Up to $1,000 First Bet on Caesars | Caesars Rewards integration, retail footprint | Expected tether to Isle Casino & Horseshoe Council Bluffs |

| Fanatics Sportsbook | Jersey Credit + Bet Bonus Offers | Merges sports betting with merchandise | Will target retail & online crossover with fan gear promos |
| bet365 | Bet $5, Get $150 in Bonus Bets (typical U.S. offer) | Known for international markets, strong live betting | Eyeing growth in Midwest; aggressive odds boosts |
| Circa Sports | Risk-Free Bet (varies) | Vegas-style sharp lines, lower hold | Likely to appeal to high-volume & savvy bettors |
| Underdog Sportsbook | Speculated: Up to $1,000 Deposit Match or “Mulligan Bet” | Clean app design, fantasy-sports crossover | Missouri will be only its 2nd sportsbook state after NC |
| Other Entrants | TBD | Could include additional casino-linked books | Missouri’s wide license model leaves room for growth |
Expected Underdog Sportsbook Features & Bonuses
While official Missouri promos have not yet been announced, here’s what bettors can likely expect based on Underdog’s current sportsbook model:
Welcome Bonus: In North Carolina, Underdog offers up to a $1,000 deposit match. Missouri could see a similar launch-day promo.
Mulligan Bet: A “first bet refund” up to a set amount has been rumored as part of its market rollout strategy.
Mobile App: iOS and Android apps will be available, with secure geolocation for Missouri users.
Payment Methods: Debit/credit cards, PayPal, and online banking are already supported elsewhere and expected in Missouri.
Why Missouri Matters for Underdog
Brand Recognition: Underdog already has a DFS user base in Missouri, giving it a built-in audience.
Competitive Edge: Entering Missouri alongside industry giants like FanDuel and DraftKings tests Underdog’s ability to differentiate with its clean app design and fantasy-driven sportsbook approach.
Growth Trajectory: A successful launch here could accelerate expansion into other states expected to regulate in 2026 and beyond.
Underdog Sportsbook Missouri is positioned to be part of a 10-operator race as the state prepares for its first legal bets this December. With a proven track record in fantasy sports, a sportsbook already live in North Carolina, and an aggressive push for licenses, Underdog could quickly carve out market share among Missouri’s sports-hungry fans.
Stay tuned: License approvals are being finalized this fall, with promotions and launch details expected to drop as the December 1 go-live date approaches.
