This market will resolve to "Yes" if Kai Wegner officially resigns from his position as Regierender Bürgermeister of Berlin by 23:59 UTC on January 31, 2026, as confirmed by an official announcement from the Berlin Senate (Senatskanzlei) or a statement from Wegner himself reported by at least two major German news outlets (e.g., rbb24.de, tagesspiegel.de, or welt.de). Otherwise, the market will resolve to "No".

Resolution will be determined using official sources such as the Berlin Senate website (https://www.berlin.de/senatskanzlei/) and contemporaneous reporting from reputable news agencies.
