Forecasters Call Iowa's 1st a Toss-up

The Race

Rep. Mariannette Miller-Meeks (R-IA) is seeking a fourth term representing Iowa's first congressional district after defeating David Pautsch in the Republican primary on June 2. She will face Christina Bohannan (D-IA), who defeated Travis Terrell in the Democratic primary, in their third consecutive general election matchup. Independent candidate Michael Bridgford and several minor-party candidates are also expected to appear on the Nov. 3 ballot. The district covers southeastern Iowa, including Davenport, Iowa City and Burlington, and has produced some of the closest House races in the country in recent election cycles.

Ratings

The nation's leading election forecasters agree that Iowa's first congressional district is one of the most competitive House races in the country. The Cook Political Report, Inside Elections, and Sabato's Crystal Ball all rate the race Toss-up, indicating neither party holds a clear advantage heading into the general election.

Prediction Markets

Prediction markets, however, favor Democrats. As of June 29, Kalshi traders gave Democrats a 66.67% probability of winning Iowa's first congressional district, compared with 33.33% for Republicans. At the time, the market had recorded approximately 5,800 contracts traded.

Experts vs. Markets

Professional election forecasters and prediction markets diverge in their assessment of Iowa's first congressional district. While traditional race ratings classify the contest as a Toss-up, indicating either party has a plausible path to victory, Kalshi's market assigns Democrats a 66.67% probability of winning. The difference suggests traders viewed Bohannan as holding an advantage despite analysts continuing to characterize the race as too close to call.

Show Us The Money

The race has attracted millions of dollars from candidates and outside groups, reflecting its status as one of the most competitive House contests of the 2026 cycle. Miller-Meeks and Bohannan have each built multimillion-dollar campaign operations, while national Republican and Democratic organizations have invested heavily in the race. According to Reuters, both candidates held more than $4 million in campaign funds following the primary, positioning the contest to be one of the most expensive House races in the country.
