This event identifies whether the Montana or New Jersey Senate race had the narrower contest in the November 2026 elections. The outcome depends on which state's voters produced the smallest vote difference between the leading candidates.
The market resolves based on which of the two Senate races—Montana or New Jersey—has the smallest margin of victory as of November 10, 2026. The margin of victory is defined as the absolute difference in vote share percentage between the first and second-place finishers, calculated using total votes cast as the denominator. If official results are unavailable by the deadline, preliminary results from source agencies with at least 95% of the expected vote will be used. In the event of a tie in margins between the two races, each tied option resolves to Yes, with the payout divided equally among the tied options.
Currently, prediction market odds offer a distinct perspective compared to traditional analyst forecasts for the Montana or New Jersey Senate race. While polls and expert opinions provide valuable insights, this market reflects the collective judgment of individuals putting their money behind their beliefs. Discrepancies between the market's implied probabilities and analyst predictions can highlight areas of disagreement or differing interpretations of available information. It’s important to consider both sources when forming your own assessment of the race.
