What to track next

  • Set an alert if probability recovers above 24¢ — that's where this move would be reversing.
  • Add to your watchlist — Home will show probability deltas since your last visit.
  • Compare against sibling markets in the same event below — divergent pricing across related contracts is the cleanest tell.

Verification actions only — never trade recommendations.

Each factor is grounded in a single named metric you can verify on this page — probability, volume, liquidity, signal, resolution state. No predictions, no prose hallucinations.

Market Description

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. If two or more candidates tie for the most valid votes in this election, and the tie is between two candidates listed, this market will resolve to the lowest margin bracket for the candidate whose listed last name comes first in alphabetical order. If the tie is between a listed candidate and an unlisted candidate, this market will resolve to the lowest margin bracket for the listed candidate. If the tie is between two or more unlisted candidates, this market will resolve to “Other.” This market will resolve based on the official vote count once the count has been made official. If the election results are not known definitively by December 31, 2026, 11:59 PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of credible reporting. In case of ambiguity, this market will resolve solely based on official election results as published by Wigan Council (https://www.wigan.gov.uk/). If a recount is initiated before the vote total has been made official, the market will remain open until the recount is completed and the vote is made official.
