The market
Missouri voters approved sports betting in a November 2024 ballot measure, and the market opened on 1 December 2025. Operators pay 10% of adjusted gross revenue, at the lower end for a state its size. Mobile licences were open to the casino operators, the professional sports teams and two untethered bidders, and only two of the eight live books came in through team partnerships.
What this means for matched betting
Missouri is the newest market in the country, open since December 2025, and new markets are where offers are at their most generous. Operators are still buying market share, the 10% tax gives them room to do it, and eight books is a wide enough field to hedge across.
