Real price history (past month), from Polymarket. Down-sampled to 24 points.
What the market is pricing
The market is pricing a first-round outright win at single-digit, unlikely odds, reflecting the expectation that a runoff will be needed. The probability has fallen 5 percentage points over the past week, suggesting growing market confidence that no candidate will clear the majority bar in one round. At this level, traders see a multi-candidate race highly unlikely to produce a first-round winner.
How this market resolves
This market resolves Yes if any candidate wins the Brazil presidential election outright in the first round on October 4, 2026—meaning they secure more than 50% of valid votes. It resolves No if no candidate reaches that threshold and a second round is required.

What could move it
- Changes in candidate polling or consolidation in the months before the October 2026 election could shift expectations about whether any candidate might reach 50% on the first ballot.
- Any formal rule change to the election process or official guidance on vote-counting would clarify the settlement mechanism, though the current framework points to a runoff scenario.
