Is Sports Betting Legal in Missouri?

Yes. Online sports betting is available in Missouri for adults 21 and older. The Missouri Gaming Commission (MGC) regulates all sports betting under Amendment 2, which Missouri voters approved in November 2024 with 50.1% of the vote — one of the narrowest gambling approvals in US history. The market launched on December 1, 2025.

This is the definitive guide to Missouri sports betting law, Amendment 2, and what it means for Missouri bettors in 2026.

What Is Amendment 2 and What Did It Do?

Amendment 2 is a constitutional amendment approved by Missouri voters on November 5, 2024. The vote was extraordinarily close: 50.1% in favor, with a margin of just 2,961 votes out of nearly 3 million cast. Because it was a constitutional amendment — not a legislative bill — it embedded sports betting directly into the Missouri Constitution, protecting the framework from simple legislative reversal.

Amendment 2 authorized:

  • Online and retail sports betting for Missouri residents and visitors 21 and older
  • Regulation by the Missouri Gaming Commission (MGC)
  • A 10% tax on adjusted gross gaming revenue
  • Promotional free-play deductions from taxable revenue
  • A maximum of 13 sports betting licences (6 tethered to existing casinos, 2 untethered mobile-only, 5 additional)

The market launched on December 1, 2025, when eight licensed operators went live simultaneously.

Who Regulates Missouri Sports Betting?

The Missouri Gaming Commission (MGC) is the regulatory authority for all sports betting in Missouri. The MGC issues licences, enforces responsible gambling requirements, monitors operator compliance, and publishes monthly revenue reports. Their website is mgc.dps.mo.gov.

Every sportsbook operating legally in Missouri holds a valid MGC licence. Never bet with an unlicensed operator.

What Sports Can You Bet On in Missouri?

Missouri has no restrictions on specific sports. Licensed Missouri sportsbooks offer markets on:

  • NFL — Kansas City Chiefs, including Super Bowl and AFC markets
  • MLB — St. Louis Cardinals and Kansas City Royals
  • NHL — St. Louis Blues
  • NBA — all teams (no local Missouri franchise)
  • College football and basketball — Mizzou Tigers and other programs

Missouri Sports Betting by the Numbers (December 2025)

The MGC released its first Sports Wagering Revenue Detail Report on January 30, 2026. Key findings:

  • Total handle: $543,039,131 in Missouri's first month
  • Mobile handle: $538,881,520 (99%+ of total)
  • Retail handle: $4,157,612 (less than 1%)
  • FanDuel handle: $212 million (39% market share)
  • Parlay wagers: $213 million — 39% of mobile handle
  • Parlay revenue: $74.2 million — 70%+ of total operator revenue
  • State tax collected: $521,220 (low due to $125M+ in promotional deductions)

The low December tax figure is a standard opening-month pattern — Michigan, Virginia, and Maryland all ran negative revenue in their first months as operators spent heavily on acquisition bonuses.

Is Online Casino Gambling Legal in Missouri?

No. Real-money online casino gambling is not legal in Missouri as of 2026. Amendment 2 authorized sports betting only — it did not open a pathway to online slots, table games, or live dealer products. There is no active ballot campaign for online casino legalisation in Missouri.

The only legal online casino-style option for Missouri residents is sweepstakes casinos — platforms that operate under US promotional sweepstakes law rather than gambling regulation. See our sweepstakes casino rankings.

Missouri Sports Betting Legislation in 2026

  • HB 3533: Filed in the Missouri House to impose an additional 24% tax on gross receipts before promotional deductions. Because Amendment 2 embedded the tax structure in the Missouri Constitution, any change would require another voter-approved constitutional amendment — making HB 3533 constitutionally unenforceable without a new ballot measure.
  • HB 2989: Passed the Missouri House 83-66 in February 2026, proposing to regulate video lottery terminals. Not related to online sports betting. Faces Senate opposition.
