In Maine’s 2026 Senate contest, traders assign Democrats an 78.5 percent implied probability largely because incumbent Republican Susan Collins faces a midterm environment in a state that backed Kamala Harris in 2024 and has trended Democratic in recent presidential cycles. Collins, the sole remaining Republican senator from New England, relies on cross-party support that has narrowed nationally. On the Democratic side, the June 9 primary has consolidated around oyster farmer and veteran Graham Platner after Governor Janet Mills suspended her campaign in late April following consistent polling deficits. Recent surveys show Platner edging Collins in head-to-head matchups, reinforcing the market’s assessment that structural and candidate-specific factors favor a Democratic outcome this November.
