Is sports betting legal in Iowa?
Yes, online and at casinos. Senate File 617, signed May 13, 2019, added sports wagering to Iowa Code chapter 99F, and the first bets were taken August 15, 2019. The Iowa Racing and Gaming Commission regulates it, and the minimum age is 21. Since January 1, 2021 you can open a betting account from your phone without visiting a casino.
Where you can bet
The Commission lists 13 licensed online operators: bet365, Bally Bet, BetMGM, BetRivers, Caesars Sportsbook, Circa Sports, DraftKings, Fanatics Sportsbook, FanDuel, Hard Rock Sportsbook, Q Sportsbook, Sporttrade and theScore Bet. Each one is tied to a state-licensed casino. Under Iowa Code 99F.7A a casino may run up to two online brands, or three with Commission approval, after paying a $45,000 initial license fee and $10,000 a year to renew.
Iowa has 19 state-licensed casinos, and 18 have a retail sportsbook. Lakeside Hotel Casino is the exception. Tribal casinos are licensed separately and aren't in that count.
College games are open for betting. The statute excludes wagers on an individual athlete's performance in a college game when an Iowa college team is playing, and it also excludes high school sports and minor league events. Licensees must also take reasonable steps to keep players, coaches, officials and people close to them from betting on events they're involved in. Iowa Code 99F.11 taxes sports wagering net receipts at 6.75%.
How Iowa legalized sports betting
From prohibition to riverboats, 1846 to 2004
Gambling of every kind was illegal in Iowa from statehood in 1846 until 1972, when voters repealed the state constitution's ban on lotteries. The legislature authorized bingo and raffles in 1973. It passed the Pari-Mutuel Wagering Act in May 1983 and created the Iowa Racing Commission that July. A state lottery followed in 1985.
Excursion boat gambling was authorized July 1, 1989, in counties that approved it by referendum, and gaming was added to the Commission's duties. The first riverboats opened April 1, 1991, in Dubuque, Bettendorf and Davenport, under a $5 maximum wager per hand and a $200 daily loss limit. The state negotiated three tribal gaming compacts in 1992. Legislation in March 1994 dropped both limits, raised the gambling age from 18 to 21 and allowed casino games at existing racetracks. A May 2004 law created a County Endowment Fund from gaming tax revenue and required casinos to offer voluntary self-exclusion.
Starting in 1997 the legislature taxed racetrack slot revenue at a rate that rose 2 points a year toward 36%, while riverboats paid 20%. The Iowa Supreme Court struck that difference down in 2002, and the U.S. Supreme Court unanimously reversed on federal equal protection grounds on June 9, 2003 (Fitzgerald v. Racing Association of Central Iowa, 539 U.S. 103). That reversal didn't end the case, because on remand the Iowa Supreme Court ruled 5 to 2 on February 3, 2004 that the tax still violated the Iowa Constitution's equality clause (Racing Association of Central Iowa v. Fitzgerald, 675 N.W.2d 1).
SF 617 and the 2019 launch
After the U.S. Supreme Court struck down the federal sports betting ban in Murphy v. NCAA on May 14, 2018, Iowa moved in the 2019 session. SF 617 passed the Senate 31 to 18 on April 17, 2019 and the House 67 to 31 on April 22. Gov. Kim Reynolds signed it May 13, 2019 (2019 Acts, chapter 132). The same bill legalized paid fantasy sports under chapter 99E.
Online operators couldn't get a license on their own. Only casino licensees could, and each online brand had to partner with one. Retail sportsbooks and online platforms opened August 15, 2019, and fantasy contests launched October 25, 2019. The law required online accounts to be opened in person at a casino until January 1, 2021, when that rule expired and remote registration began.
2026 bills on prediction markets
SF 2470 would have required a $10 million state permit and a $100,000 annual renewal to run a prediction market in Iowa, taxed adjusted revenue at 20% and added income tax rules for event-contract gains. The Senate passed it 45 to 1 on March 31, 2026. A House Ways and Means subcommittee recommended passage April 27, and the bill history shows no House action after that.
Sports betting court cases in Iowa
We found no lawsuit challenging SF 617 itself. The state's sports betting litigation comes from two fights: the 2023 college gambling investigation and Kalshi's 2026 suit over prediction markets.
The college athlete prosecutions, 2023 to 2024
The Iowa Division of Criminal Investigation formed a sports wagering team in October 2021, and the Commission gave it access to GeoComply's Kibana geolocation tool in September 2022. Agents used it without warrants to find betting apps opened in and around athletic facilities at the University of Iowa and Iowa State. In May 2023 they began questioning athletes, and at least 35 athletes and staff at the two schools were charged, lost eligibility or both.
On September 6, 2023, Iowa State quarterback Hunter Dekkers and four other athletes pleaded guilty to underage gambling and were each fined $645. That reduced charge replaced tampering with records, an aggravated misdemeanor. On March 1, 2024, Story County prosecutors dismissed the cases against Iowa State athletes Isaiah Lee, Jirehl Brock, Paniro Johnson and Eyioma Uwazurike after records showed GeoComply believed DCI had exceeded its permitted use of the tool. GeoComply revoked DCI's access on January 24, 2024. Public Safety Commissioner Stephan Bayens said he was disappointed and that prosecutors had told DCI they believed its actions were legal.
Uwazurike v. Jobes, the athletes' civil suit
Athletes from Iowa, Iowa State and Ellsworth Community College sued DCI agents on April 26, 2024 in the U.S. District Court for the Southern District of Iowa (No. 4:24-cv-00146). They claimed the warrantless geolocation searches violated the Fourth and Fourteenth Amendments. Judge Rebecca Goodgame Ebinger dismissed the case on November 5, 2025. She found the athletes had sufficiently alleged a Fourth Amendment violation but held the agents had qualified immunity because the law on app-generated geolocation data wasn't clearly established at the time.
The athletes appealed on November 13, 2025 (Eighth Circuit No. 25-3303). Judges Bobby Shepherd, L. Steven Grasz and David Stras heard argument on September 24, 2026, with 27 athletes still in the case. The panel hasn't ruled.
KalshiEX LLC v. Bird, the prediction market suit
Kalshi met with Attorney General Brenna Bird's office on March 4, 2026. Its complaint says attorneys there, including the solicitor general, questioned whether its contracts broke state gambling law. On March 11, 2026 it sued Bird and the Commission in the Southern District of Iowa (No. 4:26-cv-00109), asking for a declaration that the Commodity Exchange Act preempts Iowa's gambling and election wagering laws as applied to its event contracts. The American Gaming Association and dozens of tribes and tribal gaming groups, including the Sac and Fox Tribe of the Mississippi in Iowa, appear on the docket.
Judge Stephen Locher heard the preliminary injunction motion August 7, 2026 and denied it September 8. He held that sports event contracts are not swaps under the Commodity Exchange Act and that Kalshi was unlikely to succeed on preemption. Kalshi filed an interlocutory appeal September 15 (Eighth Circuit No. 26-2874). Its opening brief is due November 6, 2026, and the state's answer in the district court is due November 9.
Prediction markets and daily fantasy
Iowa hasn't sent a cease-and-desist letter or filed an enforcement action against any prediction market, based on our search, and the only case is Kalshi's own suit described above. A CBS Sports status page updated September 24, 2026 lists Kalshi and Polymarket as live in Iowa with sports markets. Novig, run by Ludlow Exchange, LLC and designated a CFTC contract market on June 16, 2026, excludes only Nevada, Arizona and Michigan, so Iowans 21 and older with ID can use it. It builds no vig into prices, and only takers pay fees, on live, futures and parlay trades.
On April 6, 2026 the Third Circuit affirmed an injunction for Kalshi against New Jersey, finding a reasonable chance that the Commodity Exchange Act preempts state law. The Ninth Circuit split from it on August 28, 2026, ruling against Kalshi in Nevada and holding that its sports contracts likely aren't swaps and sending the election contracts back to the district court. Before that ruling, Bird had joined a 39-state amicus brief led by Ohio and New Jersey filed there on March 10. Iowa sits in the Eighth Circuit, which hasn't ruled on preemption. Inside that circuit, Judge Katherine Menendez granted Kalshi, Polymarket US and the CFTC a preliminary injunction on July 27, 2026 against Minnesota's ban, which made hosting or advertising prediction markets a felony and was days from taking effect, and Judge Locher reached the opposite conclusion in Iowa six weeks later.
Daily fantasy is legal and regulated by the Commission under Iowa Code chapter 99E. The Commission lists two licensed operators, Crown DFS (DraftKings) and FanDuel.
