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 favors Fernando Dias da Costa at 37.8% implied probability for Guinea-Bissau's December 6 presidential election, driven by his momentum as the top challenger in the November 2025 vote annulled by a military coup that ousted incumbent Umaro Sissoco Embaló. Backed by endorsements from banned opposition leader Domingos Simões Pereira's alliance, Dias positions ahead in a fragmented field of over 10 candidates, including Siga Batista (12.4%) and Mamadu Iaia Djaló (12.0%), amid no published polls per electoral law. Transitional authorities under General Horta Inta-A Na Man—barred from running—confirmed the date on January 22 under ECOWAS pressure for constitutional restoration, with no major developments in the past 30 days heightening uncertainty ahead of candidate filings and potential runoff.
