No recent headlines matched this market. We only show an article when the names in the question appear in its headline, so a very local or very new market often has nothing. Showing nothing is deliberate: an unrelated story here would read like evidence about the price.

Headlines are matched on the names in “Will there be exactly 8 UK parliamentary by-elections in 202…”. Nobody checks them by hand, so one may not be relevant. They also say nothing about whether the price has already moved on this news.

How this market resolves

This market will resolve according to the total number of UK parliamentary by-elections held in 2026. Qualifying by-elections must be elections to the UK House of Commons for a vacant parliamentary seat, with polling day scheduled and held within the 2026 calendar year. The resolution source for this market will be a consensus of credible reporting. In case of ambiguity, this market will resolve solely based on official information from the UK Parliament (https://www.parliament.uk/).
