Will Romeu Zema finish in third place in the first round of the 2026 Brazilian presidential election?

The Zema third-place contract has collapsed 50% over seven days (from 16¢ to 8¢), suggesting significant deterioration in his polling position or shifting market sentiment about the 2026 Brazilian presidential race. The extreme implied yield of 2459% on the Yes side reflects the illiquidity and wide 6¢ spread typical of low-probability long-tail bets, with only $64K in 24-hour volume against $14.1M open interest. The 1185% realized volatility and 2.14 vol ratio indicate this market is highly unstable, making the current 8¢ price potentially unreliable as a true probability estimate given the 171 days to resolution and high cliff risk (12).

Resolution rules

A presidential election is scheduled to take place in Brazil on October 4, 2026. This market will resolve according to the listed candidate who receives the third-most valid votes in the first round of this election. The named candidates will be primarily ranked by the number of valid votes received in the specified election. If two or more candidates are tied on valid votes, ties will be broken by alphabetical order of the candidates' last names. This market will resolve to the candidate that occupies the third-highest finishing position after applying this ranking. 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/).
