**The closely matched probabilities for the next mayor of Plzeň reflect a fragmented field ahead of the October 9–10, 2026 communal elections, where the city council selects the mayor through post-election coalition talks rather than direct popular vote.** Thirteen candidate lists have registered, with established parties and new alliances positioning experienced local figures as leaders. Incumbent Roman Zarzycký heads the ANO slate, while opposition and coalition groups feature Lukáš Hegner for ODS, Aleš Tolar for STAN, Pavel Bosák for Piráti, Tomáš Morávek for Pro Plzeň with KDU-ČSL, Július Liška for SPD, and Michal Vozobule for the new Chceme Plzeň platform uniting independents, TOP 09, and Greens. Recent activity centers on finalized candidate lists and the launch of social-media campaigning, with no dominant polling shifts or major events reported in the past month to separate contenders. The balanced trader consensus captures this structural uncertainty, as the outcome hinges on vote shares across multiple parties and subsequent negotiations over the 47-seat council. Scheduled debates on transport, environment, and municipal services could influence momentum in the final weeks.
