About This Event

Iowa is expected to hold a Republican presidential primary or caucus in 2028. This market will resolve according to the candidate who wins the most votes in the Iowa Republican primary, caucus, or other official voting process by which the Iowa public directs the voting of delegates for the selection of the 2028 Republican presidential nominee. If the relevant delegate selection process is a caucus or other multi-round process, the relevant vote count will be the final round vote count that determines the apportionment of statewide delegates. The named candidates will be primarily ranked by the number of valid votes received in the specified election. If two or more candidates are tied on valid votes, ties will be broken by alphabetical order of the candidates' last names. This market will resolve to the candidate that occupies the highest finishing position after applying this ranking. If no 2028 Iowa primary, caucus, or comparable process takes place, or if the results are not definitively known by the earliest of November 7, 2028, 11:59 PM ET, or the first day of the 2028 Republican convention, this market will resolve to “Other.” The resolution source for this market will be the first official announcement of the complete results from the Iowa Republican Party; however, an overwhelming consensus of credible reporting may suffice.
