The 2026 Illinois State Treasurer election will be held on November 3, 2026, to elect the Illinois Treasurer, concurrently with elections to the United States Senate, U.S. House of Representatives, governor, and other state and local elections.

Incumbent Democratic treasurer Mike Frerichs originally considered running for Senate, but instead decided to run for re-election to a fourth term in office.[1][2] Frerichs was initially running unopposed, as no Republican candidates had filed nor declared their intention to run for treasurer, which would have made this race the first time in over 90 years that a major party did not have any candidates file for a statewide office in Illinois.[3]

Republican primary

For the first time in a century, the Republican Party failed to field a candidate for statewide office. Illinois state law allows for a candidate to be nominated by getting 5,000 or more write-in votes in the Republican primary or by the Republican Party appointing a candidate to the general election ballot after the primary if they submit 5,000 valid signatures from registered voters.[15] Max Solomon received more than 5,000 write-in votes and became the Republican nominee.[16]
