United Kingdom local elections are currently scheduled to be held on May 7, 2026. This market will resolve to "Yes" if a Reform UK candidate wins a mayorship as a result of this election. Otherwise, this market will resolve to "No". A candidate will be considered an official candidate of Reform UK if they are officially nominated by Reform UK and are registered for the relevant election in affiliation with Reform UK. Independent candidates will not count for any party. Only the following mayoral elections scheduled to be held on May 7, 2026, will qualify for this market: Croydon, Hackney, Lewisham, Newham, Tower Hamlets, and/or Watford. Temporary, interim, or placeholder mayors appointed before the election will not be considered. Resolution of this market will be based on the results of the relevant elections, once those results are official. If the results of any of the relevant elections aren’t known by April 30, 2027 11:59 PM ET, this market will resolve based on the available results up to that point. If none of the results of the relevant elections are known by that time, this market will resolve to “No”. This market will resolve based on the results of the elections as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the respective council government.Reform UK's strong projected performance in the May 7, 2026, English local elections—fueled by recent YouGov MRP polls showing significant council seat gains in London and the West Midlands amid Labour's national slump and Reform's by-election successes—has not translated to trader confidence in winning any of the six directly elected mayoral races in Croydon, Hackney, Lewisham, Newham, Tower Hamlets, or Watford. First-past-the-post voting favors incumbents like Labour Co-op's Rokhsana Fiaz in Newham and Conservatives' Jason Perry in Croydon, while Reform candidates such as Clive Furness in Newham and Mark Dixon in Watford face entrenched local name recognition and diverse electorates. Recent projections emphasize Reform's council breakthroughs over mayoral viability, anchoring the 75% "No" consensus despite broader vote share leads.
