Idaho Senate Race 2026 — Live Prediction Market Odds
Idaho is a safe Republican hold with Jim Risch running for re-election, and the market gives it barely a second look. There is no general-election edge in a state this red; the contract’s value is as a calibration point — the deep-red anchor against which the board’s genuine battlegrounds get measured.

How to read this
Each contract pays $1 at resolution, so the price in cents is the market’s implied probability — a 58¢ contract is a 58% chance. When the leading price sits near 50¢, the market is telling you the race is a genuine coin flip.
Idaho Senate 2026 — frequently asked
Who is favored to win the Idaho Senate race in 2026?
The live board above shows the current market favorite — read each contract’s price as the market’s implied probability, so a 55¢ contract is a 55% chance. Going into the cycle the seat is held by Jim Risch (Republican) and rated safe r; because a real-money market reprices continuously, take today’s favorite off the price, not a static rating.
