Resolution Criteria

The next UK general election is scheduled to be held no later than Wednesday 15 August 2029. However, the prime minister can choose to hold it at any point before this. The market resolves to the date on which polling day occurs, as confirmed by the Electoral Commission or UK Parliament official sources. Under the Dissolution and Calling of Parliament Act 2022, the prime minister has the power to request the monarch call an election at any time during the five-year length of a parliamentary session, and if the prime minister chooses not to do this, parliament is automatically dissolved five years after the day it first met.

Background

The 2024 general election resulted in a landslide victory for the Labour Party led by Keir Starmer, but with the smallest share of the electoral vote of any majority government since record-keeping of the popular vote began in 1830. Parliament first met on 9 July 2024, meaning that unless Parliament is dissolved earlier it will be automatically dissolved on 9 July 2029, and the latest an election could be held is 15 August 2029.
