Graham Platner's commanding 75% implied probability in the Maine Democratic Senate primary reflects his position as the first major declared candidate for the 2026 race against Republican Susan Collins, capitalizing on early momentum from his recent campaign launch as a former state representative and prosecutor. Governor Janet Mills trails at 24%, buoyed by her statewide popularity and past electoral success, though she has not confirmed interest amid speculation tying her to the seat. Minimal odds for Reps. Jared Golden and Chellie Pingree, Senate Majority Leader Troy Jackson, Portland Mayor Dan Kleban, and others signal trader skepticism on their entry, with no recent polls or endorsements shifting the field—traders await formal announcements ahead of the June 2026 primary.
