Description

This event tracks how decisively a candidate wins a primary election by measuring the difference in votes between the winner and the runner-up. The outcome depends on whether the vote difference falls within specific percentage ranges, reflecting either a close contest or a landslide victory.

Kalshi

The event resolves based on the margin of victory for either Luke Bronin or John Larson in the 2026 CT-01 Democratic primary. The margin is calculated as the difference in vote share between the candidate and the runner-up. If the candidate wins, the margin is positive; if they lose, it is negative; and it is zero in case of a tie for first place. Each market corresponds to a specific margin range, from 0% to 100%, with ranges inclusive of the lower bound and exclusive of the upper bound. No rounding is applied to the margin percentages. Votes for a candidate running under multiple parties or listings are summed to determine their total vote share. The market resolves to Yes if the actual margin falls within the specified range for the respective candidate.
