Resolution rules
A by-election for the United Kingdom parliamentary constituency of Holborn and St Pancras is scheduled to be held on October 8, 2026, following the resignation of incumbent Sir Keir Starmer. This market will resolve according to the margin of victory between the top two candidates in this by-election. The “margin of victory” is defined as the absolute difference between the percentages of valid votes received by the candidate who wins the most valid votes and the candidate who wins the second-most valid votes. Percentages will be determined by dividing the total number of valid votes each of the top two candidates receives by the total number of valid votes cast in the by-election. Valid vote percentages will be counted only where the official results attribute them to the candidate in question. If the reported value falls exactly between two brackets, then this market will resolve to the higher margin bracket. If a candidate standing for a party other than the Labour Party or the Green Party wins the most valid votes, this market will resolve to "Another candidate wins". If two or more candidates tie for the most valid votes, this market will resolve to the lowest margin bracket for the candidate whose party name comes first in alphabetical order. If the results of this by-election are not definitively known by June 30, 2027, 11:59 PM ET, this market will resolve to "Another candidate wins". This market will resolve based on the results of this by-election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as published by Camden Council (https://www.camden.gov.uk/).

Holborn and St Pancras Labour margin of victory?: Will the margin of victory for Labour in the 2026 Holborn and St Pancras by-election be at least 15%? Labour, ≥15%
If the margin of victory for Labour in the 2026 Holborn and St Pancras by-election is at or above 15%, then the market resolves to Yes. The margin of victory is the vote share received by Labour minus the vote share received by the candidate that finishes immediately behind Labour if Labour wins, or the candidate that finishes first if Labour loses. If Labour wins, the margin will be positive; if Labour loses, the margin will be negative; if Labour ties for first place, the margin shall be 0. No rounding is applied. Each threshold includes its lower bound and the maximum possible margin of 100 percentage points. An exact tie for first that remains unresolved by expiration receives the proportional payout specified in the full rules for every range containing zero; other ranges resolve No. Certified results, the Fully-Conducted Elections provision, and accelerated resolution apply as specified in the full rules.
