Incumbent Sen. Jim Risch commands 97% trader consensus in the Idaho Republican Senate primary due to his longstanding tenure since 2008, dominant fundraising with nearly $4 million cash on hand as of late 2025—dwarfing challengers Joe Evans, Denny LaVe, and Josh Roy—and robust establishment backing in the deeply conservative state. Absentee ballots began mailing April 9 ahead of the May 19 primary and early voting starting April 27, but no primary polls exist to suggest competition, reinforcing historical incumbency advantages in low-turnout GOP primaries. While late scandals, health issues for the 83-year-old Risch, or a surprise endorsement surge could challenge this, such shifts remain improbable given resource gaps.

If no 2026 Idaho Republican Senate Primary takes place, this market will resolve to "Other".
The resolution source for this market will be the first announcement of the results from the Idaho Republican party, however an overwhelming consensus of credible reporting may suffice.
