After many years of failed legislative attempts, legal sports wagering has finally arrived in Missouri – great news for every fan of online sports betting. The state is set to welcome licensed online betting from both professional sports betting entities and casinos on the 1st December, 2025.
Its been a long time coming and is arriving at the perfect time – the time of the college football’s final push, the latter half of the NFL season and playoffs, and the start of the college hoops too. This makes the entire wait even more exciting as sports fans will be engaged right from day one.
Online sports betting in Missouri is no longer a question of “if” but now a statement of “when”. Sports and betting fans in the state are looking forward to enjoying their favourite seasons with all that’s available at their disposal. Here is the ultimate guide to the Missouri sportsbook to keep you prepared ahead for what’s coming.
Licensing Framework and Market Landscape
Amendment 2 allows for an expansive and structured online market with six mobile licenses going to retail casinos, two being untethered (accessible by operators without local partnerships), and six to professional sports entities.
It had already been revealed this summer that Draft Kings and Circa Sports are the first two untethered licenses to operate in the MO in mid-August. So, both operators do not need to partner with the Missouri professional sports team or a retail casino in order to launch any online betting product.
Other partnerships that have been announced or assumed to be part of the list include:
- bet365 with the St. Louis Cardinals (MLB).
- BetMGM with Century Casinos.
- ESPN Bet with PENN Entertainment.
- Fanatics paired with Boyd Gaming.
- FanDuel with St. Louis CITY SC (MLS).
- Bally Bet will most likely apply and partner with Bally’s Kansas City Casino.
- Caesars is expected to obtain a license through its three MO casinos – Isle of Capri Casino Boonville, Horseshoe St. Louis, and Harrah’s Kansas City.
There is no information yet on the partnerships Hard Rock Bet and BetRivers are likely to secure but we know that Underdog has applied for license with no announcement on any partnership yet. Once it begins operating, Missouri is likely to have more online sportsbook than most states because of its expansive market structure.
