Presidential elections are scheduled to be held in Guinea-Bissau on November 23, 2025. If no candidate secures more than 50% of the valid votes in the first round, a second round will be held on November 30, 2025. This market will resolve according to the listed candidate that wins this election. This market includes any potential second round. 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 election 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 government of Guinea-Bissau, specifically the National Election Commission (Comissão Nacional de Eleições, CNE) (http://www.cne.gw/).Trader consensus on Polymarket positions Fernando Dias da Costa as the frontrunner at 27.8% implied probability for Guinea-Bissau's December 6 presidential election, driven by his strong performance as the main opposition challenger in the annulled November 2025 vote, where he claimed outright victory before a military coup ousted incumbent Umaro Sissoco Embaló and installed a transitional junta. With the junta leader Horta Inta-A Na Man barred from running and polls prohibited, the wide-open two-round race—requiring over 50% to avoid a runoff—sees a fragmented field splitting votes among independents and party figures like Siga Batista (10.3%). Key differentiators include Dias's Party for Social Renewal leadership and anti-junta resistance, contrasted by Embaló's diminished incumbency amid instability; support could consolidate via opposition coalitions, ECOWAS-mediated endorsements, or candidate withdrawals ahead of nominations.
