What are your predictions for the Democratic and Republican nominees likely to win upcoming elections, and why?

Going into the final month, Democrats are favored to win the House and, narrowly, the Senate in the November 3, 2026 midterms. My predictions give Democrats about a 92% chance of taking the House and about 63% for the Senate, with the closest Senate fights in Maine, Iowa, Ohio, Texas, Kansas, and the closest governor races in Alaska, Georgia, Nevada, Ohio, Kansas.

The 2026 midterm elections are on Tuesday, November 3, 2026. All 435 House seats are on the ballot, along with 35 Senate seats (33 regular seats plus special elections in Ohio and Florida) and 36 governor races. Below is every Senate and governor race, each candidate’s chance of winning, and why. Tap a name for that candidate’s page: who they are and what they are running on.

Who is favored to control Congress

  • House: Democrats about 92%, Republicans about 8%. Democrats need a net gain of 3 seats.
  • Senate: Democrats about 63%, Republicans about 37%. Republicans hold 53 seats to 47, so Democrats need a net gain of 4.

These are the averages based on Kalshi and Polymarket markets. A 63% chance is far from certain: something with those odds fails to happen more than 1 time in 3.

How the Senate is shaping up

Senate after November 3, if every favorite winsDemocrats favored
51 for control
Democrats 52Republicans 48

Democrats are favored in enough races to reach 52 seats, a net gain of 5. That counts the 34 Democratic and 31 Republican senators not up this year, plus whoever is favored in each of the 35 races. Vice President JD Vance breaks 50 to 50 ties, so Democrats need 51.

Adding up every candidate’s chance instead gives about 51 Democrats and 48 Republicans. Markets put Democratic control at about 63% (Kalshi and Polymarket, Oct 1). Democrats count the 2 independents who vote with them, Angus King and Bernie Sanders.
