Nicușor Dan, the former Mayor of Bucharest, was elected President of Romania on May 18, 2025, triggering a mayoral by-election scheduled to take place on December 7, 2025.

This market will resolve according to the margin of victory between the top two candidates in the 2025 Bucharest mayoral by-election.

For the purpose of this market, the 'margin of victory' is defined as the absolute difference between the percentages of votes received by the first and second-place candidates. Percentages of the votes received by each candidate will be determined by dividing the total number of votes each of the top two candidates receives by the sum of all votes cast in the 2025 Bucharest mayoral by-election.

If the reported value falls exactly between two brackets, this market will resolve to the higher range bracket.

This market will resolve based on the official vote count once the vote count has been made official.

If a recount is initiated before the vote total has been made official, the market will remain open until the recount is completed and the vote is made official.

If no by-election takes place by July 31, 2026, or the results of the Bucharest mayoral election are otherwise unknown by that date, this market will resolve to “Other.”

The primary resolution source for this market will be the official results as reported by the Romanian Government, specifically the Permanent Electoral Authority (https://www.roaep.ro/prezentare/); however, a consensus of credible reporting may also be used.
