The polling date for the May 2026 UK local elections is Thursday, 7 May 2026, with counts taking place on Friday, 8 May. The market resolves to whichever party wins the most council seats across all councils holding elections on that date. Results will be verified through official local authority election results published by individual councils and aggregated by sources such as the BBC, Electoral Commission, or House of Commons Library. The party with the highest total seat count wins, regardless of council control.

Using the May 2025 local elections as an example: Reform won 677 seats, LibDems 370, Con 319, Lab 98, and Green 79. In this scenario, Reform would have been the winning party.
