Will Renan Santos win the 2026 Brazilian presidential election?

Kalshi — primary rule

If Renan Santos is announced to qualify for the runoff in the 2026 Brazilian presidential election, then the market resolves to Yes.

Polymarket — resolution criteria

General elections are scheduled to take place in Brazil on October 4, 2026. If no candidate wins outright in the first round, the top two candidates proceed to a runoff. This market will resolve to "Yes" if the listed candidate advances to Brazil's presidential runoff election or otherwise wins outright in the first round. Otherwise, this market will resolve to "No". If the president is decided in the first round of the election but the listed candidate is not the winner or the result of this election isn't known definitively by June 30, 2027, 11:59 PM ET, the market will resolve to "No". 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/).
