Quick Answer: Is Sports Betting Legal in Iowa?
Yes, sports betting is fully legal in Iowa. Governor Kim Reynolds signed SF 617 into law on May 13, 2019. The first legal wagers were placed on August 15, 2019, at retail sportsbooks inside Iowa casinos. Mobile and online betting launched the same day.
Practically:
- Who can bet: Anyone 21 or older, resident or visitor.
- Where: Physically inside Iowa state borders at the time of the wager.
- How: At a licensed retail sportsbook inside a casino, or through a licensed mobile app.
- On what: Professional sports, college sports, esports, and other events approved by the IRGC.
- Regulator: The Iowa Racing and Gaming Commission (IRGC) is the sole licensing and enforcement authority.
Iowa was among the first states to act after the U.S. Supreme Court struck down the Professional and Amateur Sports Protection Act (PASPA) in May 2018. Iowa Code Chapter 99F provides the legal foundation. Sports wagering is specifically authorized under Iowa Code § 99F.7A, enacted by SF 617.
