The post-coup transitional process in Guinea-Bissau, following the November 2025 annulment of prior results and installation of military-led authorities, drives the fragmented trader consensus reflected in these low probabilities. Recent developments include the August 2026 constitutional referendum expanding presidential powers, approval of a December 6 election date that faces potential delay due to missed candidacy deadlines and restrictions on political activity, and the military's barring of ousted incumbent Umaro Sissoco Embaló from returning amid residency and security concerns. Fernando Dias da Costa and other listed contenders operate within a field shaped by the new electoral framework, institutional reforms, and ongoing questions over eligibility and timeline adherence. The dispersion of implied probabilities underscores the competitive uncertainty ahead of any final candidate registration and voting process.
