From Iowa House Republicans newsletter:
Last May the United States Supreme Court determined that the Professional and Amateur Sports Protection Act was unconstitutional. This ruling allowed states around the country to legalize sports wagering, without being told by the federal government that they simply could not offer it, with the exception of Las Vegas.
Sports Wagering passed through the Iowa House and the Iowa Senate with large bipartisan majorities. Sports wagering went through an extensive vetting process in the Iowa House. There were six different versions of the sports wagering bill that receive subcommittee hearings. The law received hearings from two full legislative committees (State Government & Ways & Means) before ultimately being passed by both chambers and signed into law. This piece of legislation also allowed the Iowa Racing and Gaming Commission to draft Emergency Rules.
Sports wagering will be allowed to occur at brick-and-mortar casinos. Sports wagers will also be allowed to take place online, but an individual will have to register in-person at a casino until January 2021. This bill authorized daily fantasy sports.
The Iowa Racing and Gaming Commission is currently in the process of approving their proposed rules and hope to have them ready to present to the Administrative Rules Committee in August. This should allow casinos in Iowa the opportunity to have sports wagering up and running by mid-August.
This date allows the Iowa Racing and Gaming Commission to monitor how sports wagering goes for a short period of time on just baseball, prior to the start of the college football season (August 24). However, the three Iowa Regent Universities do not start their season until the following weekend (August 31st) and many in the state anticipate that is when the bulk of the wagering in the state will begin. The NFL season does not start until September 5th.
