Presidential elections are scheduled to be held in Portugal on 18 or 25 January 2026, with a possible second round on 8 or 15 February 2026. A second round will be held if no candidate secures more than 50% of the valid votes in the first round. This market will resolve according to the listed candidate that receives the highest number of valid votes in the first round of this election in the Lisbon District (Distrito Lisboa). If the result of this election isn't known by December 31, 2026, 11:59 PM ET, the market will resolve to "Other". This market will resolve based on the result of the first round of this election in the Lisbon District, as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the Portuguese government, such as on the Website of the Portuguese Ministry of Internal Administration (Ministério da Administração Interna) (https://www.eleicoes.mai.gov.pt/), or the National Election Commission (Comissão Nacional de Eleições, CNE) (https://www.cne.pt/).
