This prediction market focuses on the outcome of Michigan's 11th congressional district House election in the 2026 midterm elections. The market resolves based on which political party wins this U.S. House seat, with the election scheduled for November 4, 2026. Party affiliation will be determined by the candidate's ballot-listed or otherwise identifiable party designation when major media outlets and election authorities conclusively call all 2026 House races. Michigan's 11th district covers parts of Oakland and Wayne counties, including suburbs northwest of Detroit such as Troy, Rochester Hills, and Farmington Hills. The district is currently represented by Democrat Haley Stevens, who has held the seat since 2019. The 2026 election will occur during a presidential administration's second midterm, a historical period that typically produces significant congressional seat shifts. Political observers monitor this district because it represents a classic suburban battleground where demographic changes and national political trends directly influence local outcomes. The race attracts attention from national party committees and political action committees that view Michigan as essential for controlling the House of Representatives. District boundaries were last redrawn in 2022 following the 2020 census, creating a slightly more Democratic-leaning constituency than previous versions. Voter registration data from the Michigan Secretary of State shows Democrats with a narrow advantage in active registrations, though independent voters constitute the largest bloc. The 2024 presidential election results in this district will provide important indicators for the 2026 House race, particularly regarding suburban voting patterns.

Historical Context

Michigan's 11th congressional district has undergone substantial geographic and political changes over the past two decades. The district was created following the 2000 census and was originally represented by Republican Thaddeus McCotter from 2003 to 2012. McCotter resigned in 2012 amid a petition signature scandal, leading to a special election won by Democrat David Curson, who served only the remainder of the term. Republican Kerry Bentivolio won the redrawn district in 2012 but lost the 2014 Republican primary to Dave Trott. Trott represented the district from 2015 to 2019, announcing his retirement in 2018. The 2018 election marked a significant shift when Democrat Haley Stevens defeated Republican Lena Epstein by 6.7 percentage points, flipping the seat during a Democratic wave election. Stevens has since won three re-election campaigns, though her margins have varied. She won by 19.8 points in 2020 during a strong Democratic presidential year, then by 7.4 points in 2022 during a more competitive midterm environment. The district boundaries changed substantially in the 2022 redistricting cycle following Michigan's independent citizen redistricting commission process. The new map, first used in the 2022 election, made the district slightly more Democratic by including more of Rochester Hills and less of western Wayne County. According to Dave's Redistricting App analysis, the new district would have voted for Joe Biden by approximately 8 percentage points in the 2020 presidential election, compared to a 4-point Biden margin under the previous boundaries.
