18+ Sports Betting In Missouri
Missouri was very late to the party but passed domestic sports betting in 2024. Local, online, and mobile sports betting started in 2025. Local sports betting is only offered to players who are 21 and older, leaving the 20-and-under demographic out in the cold.
Some states have opted to exclude local college programs from any betting lines offered at their local books, but Missouri legislators did not put that language into Amendment 2. That means bets can be made on the Missouri Tigers football, basketball, and baseball teams locally.
Since the minimum age is 21 to bet on sports in MO, no one 20 or under can place a wager at a state-regulated sportsbook. There are 18+ sports betting sites that cater to area players, and you can find the best-of-the-best ranked here on this page.
By clicking on the links we've provided, you can tour these eighteen-friendly online sportsbooks without creating an account. Take a few minutes to look around each one of them to see why they've earned our highest ratings.

Online sports betting in MO is now legal, but the minimum age to log in and gamble is 21. If you are inside the state and at least 21, you can access domestic online sportsbooks using any web-ready device that has a browser installed.
If you are not yet 21, there are some online gambling options at your disposal. Numerous online sportsbooks that are based overseas will accept players in the Show Me State and let them wager on any pro or college sport or match.
These websites can legally accept 18+ clientele from inside MO because that is the minimum age to gamble in their home jurisdiction. Local gaming commissions permit these sites to do business internationally, and they routinely inspect these books for legitimacy.
Until MO lowers the minimum wage to 18, these websites are the only legal option for gambling on sports at under 21.
Best Missouri Sports Betting Sites For 2025
Is Sports Betting Legal In Missouri?
Yes. Sports betting in MO was made legal in 2024 when voters approved Amendment 2 at the ballot box by a very slim margin. Sportsbooks will debut in 2025 and will be offered online, on mobile devices, and at local retail venues.
These local sportsbooks are limited to 21 and older clientele. No one 20 or under is allowed to place a wager on sports at a domestic sportsbook. There is potential for the minimum age to be reduced by the introduction of future gambling bills, but that possibility isn't likely because 21 is fairly standard across the country. Anyone wanting to use a state-regulated sportsbook at 18 or under will have to travel to Tennessee and use their mobile options.
The sportsbook sites that we suggest in this guide are located overseas and can legally offer sports betting online to 18-year-olds in Missouri because their regulations allow them to. Because of their international status and gambling laws, they can accept bets on the web from customers in the USA and many other countries.
Is Online Sports Betting Legal In Missouri?
Yes, local online sportsbooks became legal in 2024, with a debut date set for 2025. These sportsbook sites can be used anywhere in the state, 24 hours a day, by anyone that is 21 or older. Wagers can be placed on laptops, PCs, and mobile devices.
Another option for sports betting over the web in MO is to use an offshore sportsbook site. They are legal to use in MO, and many of them accept gamblers under 21. We're not suggesting that all overseas gambling sites are legitimate, but you can trust the brands we recommend here.
Each sportsbook site that we list in this guide has been vetted by our team and is regulated and licensed by a respected international gaming authority. No laws are violated by accessing and betting on sports with these brands while inside MO.
Missouri Betting Apps
Gambling on mobile devices is the preferred method by a majority of players these days, especially in Missouri. The distance between retail locations is vast, so being able to wager on the go using smartphones and tablets is incredibly convenient.
The only state-regulated betting apps in MO at this time are mobile sportsbooks. These sports betting apps are off-limits to anyone under 21 and can be used to wager on pro or college sports for teams in MO and around the country.
Online casino gambling (aka eGaming) is not permitted in MO and doesn’t seem to be on the radar of local politicians. This is a feature only offered in a few states at this time, but could definitely spread into MO before long.
Offshore gambling apps are legal in Missouri and are open to players who are 18 and up. These apps are listed here throughout this guide and allow their customers to bet on sports, play casino games, and real money hands of poker, all on Apple and Android devices.
Unlike state-regulated applications, our favorite sites offer their services over the web and can be accessed just like you would using a standard computer. You don't need to download anything - just log in to your account using a web browser app and start gambling.
