This market will resolve according to the winner of the Democratic Primary for United States Senator from Maine. If no 2026 Maine Democratic 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 Maine Democratic party, however an overwhelming consensus of credible reporting may suffice.

Trader consensus on Polymarket heavily favors Graham Platner at 73.5% implied probability to win Maine's Democratic US Senate primary, reflecting his early announcement, robust fundraising exceeding $500,000, and endorsements from key labor unions and progressive groups that bolster his organizational edge. Governor Janet Mills trails at 26%, buoyed by her statewide name recognition and 55% approval rating but tempered by her focus on gubernatorial duties amid state budget battles; her potential entry remains unconfirmed despite speculation. Rep. Jared Golden sits at 0.1%, hampered by his competitive House reelection. Recent catalysts include Platner's viral debate performance last week and a Portland Press Herald poll showing him up 15 points, with the June 11 primary looming as the next market mover.
