This year’s filing deadline for candidates running for the U.S. House of Representatives in Indiana was Feb. 6, 2026.

This year marks the first time since 2014 in which no districts are open, meaning all incumbents — two Democrats and seven Republicans — are running for re-election this year. There were three open districts in 2024, one in 2022, two in 2020, two in 2018, two in 2016, and none in 2014.

Fifty-three candidates — 36 Democrats and 17 Republicans — are running for Indiana’s nine congressional districts. That’s 5.9 candidates per district. There were seven candidates per district in 2024, 5.4 in 2022, 8.7 in 2020, 7.9 in 2018, 5.7 in 2016, and 5.4 in 2014.

Fourteen primaries — eight Democratic and six Republican — are contested this year. In total, there were 14 contested primaries in 2024, 12 in 2022, 15 in 2020, 15 in 2018, 16 in 2016, and 13 in 2014.

Incumbents — two Democrats and four Republicans — are running in six of those contested primaries. There were four incumbents in contested primaries in 2024, three in 2022, four in 2020, four in 2018, seven in 2016, and six in 2014.

Eleven candidates are running for the 4th Congressional District, the most in any district this year. The candidates running in the district include incumbent Rep. Jim Baird (R), two other Republicans, and eight Democrats.

Candidates filed to run in the Republican and Democratic primaries in all nine districts, meaning no districts are guaranteed to either party.

Indiana and one other state — Ohio — are holding U.S. House primaries on May 5, 2026.

In Indiana, the winner of a primary election is the candidate who receives the greatest number of votes, even if they do not win an outright majority of votes cast.
