Missouri Legal Sports Wagering Under Amendment 2

Missouri legalized sports wagering constitutionally, not by ordinary statute. Amendment 2, approved by voters in November 2024, added Article III, Section 39(g) to the Missouri Constitution, declaring that 'the interests of the public are best served by a well-regulated sports wagering industry that will provide substantial tax revenue to support educational institutions in Missouri.' The provision authorizes and structures the market directly rather than leaving it to the legislature.

Licensing runs through the Missouri Gaming Commission, the same agency that regulates the state's excursion gambling boats. Retail licenses go one per qualified applicant to each of Missouri's licensed casinos and to each 'sports district', defined in the text as the grounds of a venue with at least 11,500 seats where a professional team plays home games, plus the surrounding 400 yards. Mobile/online licenses follow the same one-per-casino-or-team pattern, but the Commission may also issue up to two additional mobile licenses directly to sports wagering operators with no in-state casino or team tie, the path national brands used to enter without a local partner. 'Sports wagering' covers wagering on professional or collegiate athletic and competitive events involving human participants, including esports; fantasy sports contests are defined and treated separately, not as sports wagering.

Every licensee must card bettors: the text states flatly that 'a licensee shall not offer sports wagering to individuals who are under twenty-one years of age.' Operators pay a 10% tax on adjusted gross revenue; from that revenue, the Compulsive Gaming Fund receives whichever is greater, 10% of the annual tax take or $5,000,000, with the balance directed to Missouri's public schools. The constitution set a hard deadline, requiring 'a start date for all sports wagering that is not later than December 1, 2025,' which the Commission met with a licensed launch that year.

Missouri has no standalone 'illegal sports betting' statute: wagering outside a Commission-licensed operator falls under the general gambling offense, RSMo 572.020: 'A person commits the offense of gambling if he or she knowingly engages in gambling,' a class C misdemeanor, rising to a class A misdemeanor for a 'professional player.' Licensed operators that violate Chapter 313 or license conditions face Commission discipline, fines, or revocation rather than criminal charges; underage bettors are turned away at registration under the constitution's 21-and-over line.
