The next Osnabrück mayoral election is scheduled to be held on September 13, 2026, to elect the mayor of Osnabrück, Germany (Oberbürgermeister der Stadt Osnabrück). A runoff election is scheduled for September 27, 2026, if no candidate receives more than half of the valid votes in the first round. This market will resolve according to the candidate who becomes the next mayor of Osnabrück as a result of this election. Temporary, interim, or placeholder mayors appointed before the election will not be considered. If the result of this election isn't known by April 30, 2027, 11:59 PM ET, the market will resolve to “Other.” The primary resolution source for this market will be a consensus of credible reporting; however, if there is any ambiguity in the results, this market will resolve according to official information from the Stadt Osnabrück, including its election office and municipal election committee.**Incumbent Katharina Pötter (CDU) leads the Osnabrück Oberbürgermeister race ahead of the September 13, 2026 direct election and possible September 27 runoff.** Her position stems from established name recognition after taking office in 2021 and her party's unanimous nomination in June 2026. The field remains fragmented, with SPD candidate Robert Alferink, Green nominee Volker Bajus, and smaller-party contenders including AfD's Thorsten Wassermann and Die Linke's Thomas Groß unable to consolidate opposition support. Recent party candidate selections have clarified the lineup without altering the structural advantage for the sitting mayor. Trader consensus prices in Pötter's edge while assigning limited probability to any single challenger prevailing or forcing a runoff in the final campaign weeks.
