3 prediction markets price this story:

• Will voter turnout in the second round of the 2026 Brazil presidential election be 76-78%? — resolved “No” on 26 Oct 2026. The outcome depends on the official voter turnout percentage in Brazil's second presidential election round on October 25, 2026. The Yes outcome occurs if the turnout is between 76% and 78%, inclusive; otherwise, it resolves to No. Readers often mistake the resolution deadline of June 30, 2027, for the election date, but the market uses only the final official turnout figure from Brazil's Superior Electoral Court.
• At least 125,000,000 — resolved “Yes” on 26 Oct 2026. The outcome is Yes if at least 125 million votes are cast in the second round of the 2026 Brazilian presidential election, including blank and null votes. The outcome is No if fewer than 125 million votes are cast. Readers often mistake the deadline for the first round or overlook that blank and null votes count toward the total.
• Will Flávio Bolsonaro win the second round of the 2026 Brazilian presidential election by 2–4%? — resolved “No” on 26 Oct 2026. The market resolves based on the final official vote count from Brazil's Superior Electoral Court after the October 25, 2026 runoff. It pays out 'Yes' if Flávio Bolsonaro wins by a margin of exactly 2 to 4 percentage points among valid votes. Readers often mistake the deadline for the election day itself, but the resolution depends on when the official count is finalized, which can extend until June 30, 2027.
