Market Discussion
The market heavily anticipates a Republican victory in the 2026 Montana Senate race, with Kurt Alme currently holding a 91.5% probability, supported by Montana's recent strong Republican presidential election margins and a R +9.4 margin forecast. Independent Seth Bodnar is a distant second at 7.8% despite significantly out-raising Alme in campaign funds ($4.7M vs. $2M) and campaigning on affordability and anti-corruption. There is a strong consensus that a Republican will win, with the Democratic candidate, Alani Bankhead, having negligible chances at 0.2%.
