Resolution rules

If Fernando Haddad wins the 2026 São Paulo gubernatorial election, then the market resolves to Yes. For parliamentary elections, the party or coalition with the most seats wins. If two parties tie in seats: the one entering government will resolve to YES and all others to NO If both or neither enter government, the one with the higher share of the vote will resolve to YES and all others to NO For coalitions/alliances, only those formally registered with electoral authorities before the nomination deadline count, not post-election governing arrangements Overhang seats, leveling seats, and appointed seats count only if specified For referenda/plebiscites, the specified option achieves the required threshold per applicable law (simple majority, supermajority, dual majority, turnout requirements). If multiple thresholds exist (e.g., majority of votes AND majority of states), all must be met For presidential or direct elections, the candidate who wins according to the electoral system (electoral college, popular vote, or runoff as applicable) and either (i) is inaugurated/sworn in/takes office, or (ii) the scheduled inauguration date passes without a different candidate taking office is the winner. The market resolves based on the official certification or declaration by the relevant electoral authority Contested results are resolved based on the final certified outcome by the appropriate electoral authority or highest court with jurisdiction In cases of competing claims (two presidents, disputed succession), the individual recognized by the hierarchical majority of Source Agencies prevails The market remains open until the rescheduled election or two years from the original date, whichever comes first Repeated postponements count towards the 2-year deadline If results are annulled by a court/authority AFTER announcement but BEFORE the winner takes office, the Contract remains open until re-run election or expiration

Comparable, not identical. Polymarket uses credible reporting, with TSE results as the definitive source and a June 30, 2027 fallback; Kalshi uses official certification and may remain open for postponements or disputes under its general rules. These are settlement-rule differences and do not materially change the event being measured.

    Will Fernando Haddad win the 2026 São Paulo gubernatorial election?

    The São Paulo gubernatorial election is scheduled to take place in Brazil on October 4, 2026, with a runoff on October 25, 2026, if no candidate receives a majority of the valid votes in the first round. This market will resolve according to the candidate who wins this election. Temporary, interim, or placeholder governors appointed by any means before the specified election will not be considered. 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., www.tse.jus.br/eleicoes/resultados-eleicoes).
