Will Renan Santos win the first round of the 2026 Brazilian presidential election?
Prediction markets currently give a 5% probability that Will Renan Santos win the first round of the 2026 Brazilian presidential election?. This contract trades at 5¢ on Polymarket, closing October 4, 2026. The 5-cent price reflects an extremely illiquid long-shot bet on Santos advancing to a runoff, with the massive 4063% implied yield on the Yes side indicating severe mispricing relative to the $23.2M open interest—a classic sign of trapped capital in a low-probability outcome.
Analysis
The 5-cent price reflects an extremely illiquid long-shot bet on Santos advancing to a runoff, with the massive 4063% implied yield on the Yes side indicating severe mispricing relative to the $23.2M open interest—a classic sign of trapped capital in a low-probability outcome. The 7-day price stability (4¢ to 5¢) and near-zero spread mask concerning cliff risk (19/100), suggesting potential liquidity evaporation as the October 2026 election approaches, while the neutral regime score indicates no clear directional momentum despite the outsized yield differential.
Resolution rules
A presidential election is scheduled to take place in Brazil on October 4, 2026. This market will resolve according to the margin of victory between the top two candidates in the first round of the next Brazil Presidential Election. For the purpose of this market, the “margin of victory” is defined as the absolute difference between the percentages of valid votes received by the first- and second-place candidates. Percentages of the valid votes received by each candidate will be determined by dividing the total number of valid votes each of the top two candidates receives by the sum of all valid votes cast in the election. If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. This market will resolve based on the official vote count once the vote count has been made official. If a recount is initiated before the vote total has been made official, the market will remain open until the recount is completed and the vote is made official. If the result of this election isn't known definitively 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/).
