Kalshi
Description
This event tracks the performance of a candidate in a Democratic primary election for a U.S. Senate seat in Maine scheduled for 2026. The market measures the candidate's share of the popular vote in the primary election based on certified results.
Kalshi
Resolution is based on the certified percentage of popular votes received by Graham Platner in the 2026 Maine Democratic Senate primary, calculated as total votes received divided by total valid votes cast, multiplied by 100. The percentage is rounded to specified decimal places. Resolution uses only certified official results, not preliminary counts. Write-in votes are included if they appear in certified results; invalid, spoiled, or rejected ballots are excluded from both numerator and denominator. For ranked choice voting, the percentage is based on the first round unless otherwise specified. If multiple rounds occur, the specified round determines the percentage. In case of recount before expiration, the most recent certified percentage is used. If the election is cancelled, postponed beyond market expiration, or no certified results are available by expiration, the market resolves to No.
