Maine Senate winner? (Person)
15 markets · 11mo
The Maine Senate race is a competitive open-seat contest (though incumbent Susan Collins is running) where Collins is the most likely individual winner at 44%, but a majority of the market probability is on other candidates, especially Troy Jackson (29%) and Nirav Shah (11%), indicating a potential Democratic flip is taken seriously.
What's driving it
- • Susan Collins's 44% win probability is below the typical incumbent re-election rate, reflecting her moderate profile and the national political environment (no clear catalyst recently).
- • Troy Jackson's 29% probability suggests he is the leading Democratic challenger, likely drawing on his state Senate leadership experience (no clear catalyst recently).
- • The combined 56% probability that Collins does not win indicates the market sees a competitive race with multiple plausible outcomes.
- • Nirav Shah's 11% probability, despite being a prominent public health figure, suggests his name recognition is not yet translating into a dominant challenge (no clear catalyst recently).
The bullish case
- • Collins has a strong incumbency advantage and a history of winning in a state that leans Democratic at the presidential level, appealing to moderate voters.
- • The market's 44% probability for Collins is still the highest among all candidates, suggesting she is the clear frontrunner.
- • No other candidate has broken above 30%, so the opposition is fragmented, which could benefit Collins in a multi-candidate general election.
The bearish case
- • The market assigns a 56% probability to Collins losing, reflecting broad uncertainty about her re-election prospects in a favorable national environment for Democrats.
- • Troy Jackson (29%) and Nirav Shah (11%) represent a strong Democratic bench, and the party's focus on Maine could consolidate support behind a single challenger.
- • Maine's ranked-choice voting system could work against Collins if multiple moderate candidates split the vote, though it also complicates path to victory for any challenger.
What to watch
- • The filing deadline for the 2026 Maine Senate race (likely early 2026) will formalize the candidate field and could shift odds if high-profile candidates drop out or enter (likely direction: increase for Collins if no strong challenger emerges, decrease if a major Democrat enters).
- • The Maine Democratic primary (expected June 2026) will determine the main challenger, likely consolidating support behind one candidate (likely direction: increase for the winner of the primary, possibly decreasing Collins's odds if the winner is strong).
- • General election polling results in 2026, especially from independent firms, will provide concrete evidence of race dynamics (likely direction: move odds toward the candidate with momentum).

Who will win the 2026 Maine Senate election? — Brian Bryant
The market's 0% Yes price reflects that Brian Bryant is not a recognized candidate in the Maine Senate race; the only candidate discussed in recent headlines is Graham Platner, and Bryant's public appearances are solely as a union president, not as a political contender.

Who will win the 2026 Maine Senate election? — Susan Collins
Collins is a 4-term incumbent in a state that has trended blue, but the recent ICE shooting and Democratic primary debates have given her opponents a clear line of attack, yet no single strong challenger has emerged, keeping the race competitive but tilted toward a No resolution.
Yes ≈ 39% chance
Who will win the 2026 Maine Senate election? — Nirav Shah
Yes ≈ 0% chance
Who will win the 2026 Maine Senate election? — Janet Mills
The market prices Janet Mills's Senate victory at 0% because she is not a declared candidate and recent reporting shows she is focused on replacing the current Democratic nominee, not on running herself.
Yes ≈ 0% chance
Graham Platner
Graham Platner's odds are near zero because his own party is actively replacing him after a scandal, making a victory virtually impossible unless he mounts an independent campaign, which remains highly unlikely given the coordinated effort to move on.
Yes ≈ 0% chance
