This market will close early following the swearing in of the Senator for the seat in question.
Current Market Outlook
Kalshi traders give Republicans a 64% chance of winning Iowa's Senate seat in 2028. That's a moderate confidence level, meaning the market sees the GOP as the clear favorite but not a lock. Iowa has shifted hard right over the past decade. Trump won the state by 8 points in 2020 and 13 points in 2024. Senator Chuck Grassley, who has held the seat since 1981, will be 95 years old when the 2028 election rolls around. If he retires, the open seat dynamics could shift the race.
Key Factors Driving the Odds
Iowa's political transformation is the main factor. The state voted for Obama twice, then flipped to Trump by 9 points in 2016. That shift accelerated. In 2022, Republican Governor Kim Reynolds won reelection by 19 points. The state legislature is firmly GOP-controlled. Any Republican candidate starts with a structural advantage.
The other factor is candidate quality. Governor Reynolds is the most likely GOP nominee if Grassley retires. She has a 57% approval rating in Iowa, higher than any Democrat in the state. On the Democratic side, no obvious top-tier candidate has emerged. Former Congresswoman Cindy Axne lost her seat in 2022. The party's bench is thin after consecutive statewide losses.
What Could Change These Odds
Grassley's decision is the wildcard. If he runs again, Democrats could make the race about age and seniority. Grassley won by 12 points in 2022, but his approval has softened. A 2024 Des Moines Register poll showed 42% of Iowans think he should retire.
National environment matters too. If 2028 is a wave year for Democrats, Iowa could become competitive again. The state still has a sizable number of swing voters in the suburbs of Des Moines and Cedar Rapids. A Democratic nominee like former state senator Rob Hogg or a moderate business figure could cut into Republican margins.
The market is pricing in the baseline Republican advantage. But 64% leaves room for a competitive race if Grassley retires or national winds shift.

Overview
The 2028 Iowa Senate election will determine who represents Iowa in the United States Senate for a six-year term beginning in January 2029. Iowa has two Senate seats, and this particular race is for the Class 3 seat, currently held by Republican Chuck Grassley. Grassley, first elected in 1980, will be 95 years old in 2028 and has not announced whether he will seek reelection. The outcome of this race could shift the balance of power in the Senate, which is closely divided between Democrats and Republicans. Iowa has trended Republican in recent presidential elections, but Democratic candidates have won Senate races in the state as recently as 2020. The 2028 contest will be shaped by national political trends, candidate quality, and the state's evolving demographics. Voter turnout and campaign spending are expected to be high, with both parties viewing Iowa as a potential pickup opportunity depending on who retires or challenges for the seat.
Historical Context
Iowa has a long history of competitive Senate races. The state's Class 3 seat has been held by Republicans since 1981, when Chuck Grassley first took office. Before that, Democrat John Culver held the seat from 1975 to 1981. The Class 2 seat, currently held by Joni Ernst, was held by Democrat Tom Harkin from 1985 to 2015. Iowa's Senate races have often been close. In 2020, Joni Ernst won reelection by 6.6 percentage points, while in 2014, she won by 8.4 points. The 2022 race saw Grassley win by 12 points, but that was against a relatively unknown opponent. The state has voted Republican in the last four presidential elections, but Democrats have won Senate races in the same period. The 2028 election will be influenced by the presidential race, as Iowa is expected to be a key swing state. The state's population has grown slowly, and its electorate is older and whiter than the national average, factors that affect turnout and candidate appeal.
Why It Matters
The Iowa Senate race in 2028 will be one of the most watched contests in the country because it could determine control of the Senate. The chamber is currently split 50-50, with Vice President Kamala Harris breaking ties. A single seat flip could shift the majority. Iowa's Senate race also reflects broader political trends in the Midwest, a region that has become a battleground between the parties. The outcome will affect federal policy on agriculture, trade, healthcare, and judicial appointments. Iowa is the largest corn and soybean producer in the United States, and its senators have outsized influence on farm policy. The race will also test the strength of the Republican Party in a state that has moved rightward but still elects Democrats to local offices. Campaign spending in Iowa Senate races has exceeded $50 million in recent cycles, with outside groups contributing heavily. The result will signal whether the Democratic Party can compete in rural states or if the Republican trend continues.
Current Status
As of 2024, Chuck Grassley has not announced whether he will seek reelection in 2028. He has said he will decide closer to the election. Potential Republican candidates include Governor Kim Reynolds, who has not ruled out a Senate run, and state officials. On the Democratic side, no clear frontrunner has emerged, but former Representative Abby Finkenauer and state party chair Rita Hart are mentioned as possibilities. The national parties are already preparing for a competitive race, with both the Democratic Senatorial Campaign Committee and the National Republican Senatorial Committee listing Iowa as a target state. Early polling shows a generic Republican leading a generic Democrat by single digits, but the race remains fluid.
