Missouri has legalized sports wagering for individuals aged 21 and older with the passage of Amendment 2. The measure was officially called by the Associated Press last week and passed with 50.05 percent of the vote. Missouri is the 39th state to legalize sports betting, according to the American Gaming Association. The amendment will take effect in 30 days and requires wagering to be established no later than December 1, 2025.
The measure was put on the ballot after a mass signature gathering effort from the state's professional sports teams—led by the St. Louis Cardinals. With the amendment passed, Missourians will no longer have to go to neighboring states to place wagers. Since the start of the 2024 National Football League season, residents have unsuccessfully tried to place more than 11 million bets in other markets while in Missouri. Nearly 40 percent and 57 percent of these wagers were attempting to access legal sportsbooks in Kansas and Illinois, respectively.
