United Kingdom local elections are currently scheduled to be held on May 7, 2026. This market will resolve to "Yes" if a Green Party 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 the Green Party if they are officially nominated by the Green Party and are registered for the relevant election in affiliation with the Green Party. 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.Trader consensus prices a Green Party mayoral victory at 88.5% implied probability ahead of the May 7, 2026, local elections, reflecting the party's surge in London borough polls and strong positioning in key contests like Hackney and Lewisham. Recent April polling, including an Electoral Calculus survey showing Greens tied with Labour at 36% in Hackney—Zack Polanski's home borough—has fueled optimism, alongside the party's campaign launch on affordable housing and criticisms of Labour's record. Bolstered by a landmark February by-election win over Labour and rising support among disillusioned voters, traders see low barriers to at least one upset in the six directly elected mayor races, though late turnout shifts or Labour consolidation could narrow the path.
