Resolution rules

Rules as stated by Polymarket, reproduced verbatim. Convexly has not independently reviewed them and does not endorse them; the rating's resolution-reliability pillar treats rule text as present but not independently reviewed.

A presidential election is scheduled to take place in Brazil on October 4, 2026. 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 June 30, 2027, 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 Brazilian government, specifically the Superior Electoral Court (Tribunal Superior Eleitoral, TSE) (e.g., https://dadosabertos.tse.jus.br/).Show the full rules text

Certainty reflects how much of this market we measured, not how good the market is.

How it adds up: composite = Σ(score × weight) / Σ(weight) across measured + heuristic pillars only. Pending and data-rights-blocked pillars are excluded from both numerator and denominator. Total contributing weight = 70.0.

Caveat: 2 pillars not assessed yet; the score will recompute as the substrate fills in.
