The vote that made Missouri sports betting legal
Sports betting is legal in Missouri because voters put it there: it arrived by citizens' initiative rather than through a bill. Amendment 2 added Article III, Section 39(g) to the Missouri Constitution and set a hard deadline: betting had to start no later than December 1, 2025. The margin was 2,961 ballots out of almost three million cast on the question.

Legal Missouri sports betting apps
The amendment gives every casino owner and every professional team in the state a retail and a mobile license, and lets the Commission award up to two more mobile licenses directly to operators. Those two went to DraftKings and Circa. The Missouri sports betting apps below are the eight mobile licensees on the Commission's list; "temporary" licensees take bets while their full licensing is completed.

Taxes and where the money goes
Under the amendment's tax rules, operators pay 10 percent of adjusted gross revenue, and they may deduct promotional credits up to 25 percent of a month's cash receipts. The tax first covers the Commission's costs; then the greater of $5 million or 10 percent goes to the Compulsive Gaming Prevention Fund, and the remainder to education. A 2026 bill that would have added a 24 percent sports betting tax was stripped of that provision in committee and stalled in May.
Fantasy, pick'em and prediction markets
Fantasy contests are licensed separately from sportsbooks. PrizePicks (under its company name SidePrize) and Underdog hold Missouri fantasy licenses, and their fantasy products remain available.
In September 2026 the Attorney General sent cease-and-desist letters to Kalshi, Polymarket, Robinhood, Crypto.com, Novig and Underdog, taking the position that sports event contracts are sports wagering and need a Missouri license.
In October 2026 PrizePicks stopped accepting new Team Picks entries from people located in Missouri, citing updated legal requirements; its fantasy Player Picks stayed available.
