Will Andy Burnham win the 2026 Makerfield by-election by 9% or more?

A by-election for the United Kingdom parliamentary constituency of Makerfield is expected to be held in June 2026 following the announced resignation of incumbent Josh Simons.

This market will resolve according to the margin of victory between the top two candidates in the specified election.

For the purpose of this market, the “margin of victory” is defined as the absolute difference between the percentages of valid votes received by the first-place and second-place candidates. Percentages of the valid votes received by each candidate will be determined by dividing the total number of valid votes each of the top two candidates receives by the sum of all valid votes cast in the election.

If the reported value falls exactly between two brackets, then this market will resolve to the higher placed bracket.
