Missouri Legal Sports Betting Amendment Passes, Regulated Betting by Dec. 2025

  • Missouri residents successfully passed a constitutional amendment that brings a state-regulated sports betting industry to the Show Me State.
  • Retail and online sportsbooks in the state must launch before Dec. 1, 2025.
  • Missouri anticipates up to $28.9 million in annual tax revenue from sports betting.

KANSAS CITY, Mo.Missouri voters narrowly passed Amendment 2 in Tuesday’s election, meaning a state-regulated legal sports betting industry is on the way. Eager bettors can expect retail and online sports betting options before Dec. 1, 2025.

A difference of 7,486 votes determined that online sportsbooks will finally come to Missouri through state-regulated sportsbooks, as 1,469,866 people voted yes and 1,462,380 voted no. With the approval of Amendment 2, Missouri professional sports teams and brick-and-mortar casinos are eligible for one retail and one online sports betting license each.

They also can partner with an online sportsbook, like FanDuel Sportsbook becoming the official sportsbook of the Kansas City Chiefs for example. The formula will look similar to North Carolina sportsbooks, as sportsbooks earned their entry into the state through partnerships with the Carolina Panthers, Charlotte Hornets, and other professional organizations or venues, except Missouri’s framework will allow up to 19 retail sports betting licenses and 21 online compared to North Carolina’s 11 licenses.

Details For Legal Missouri Sports Betting Launch

Per the amendment that passed on Tuesday, Missouri sports betting must launch by Dec. 1, 2025. Residents can expect to have state-regulated betting options before that, as Kentucky and North Carolina took less than nine months to launch after authorizing legislation this year.
