PolymarketRules
If the certified percentage of the popular vote received by Flávio Bolsonaro in the second round of the 2026 Brazilian presidential election is 52% to 100%, inclusive of both endpoints, then the market resolves to Yes.
Settles via:Tribunal Superior Eleitoral (TSE)
- The percentage is Flávio Bolsonaro's share of the valid votes cast in the second round (runoff), calculated as votes received divided by total valid votes cast, times 100, rounded to two decimal places. Except as provided by the Fully-Conducted Elections and Accelerated Resolution provisions in the Contract, resolution uses certified official results from the Tribunal Superior Eleitoral, not preliminary results. Invalid, spoiled, blank, and rejected ballots are excluded from both numerator and denominator. If a recount changes the certified percentage before expiration, the most recent certified percentage is used.
