Peru Election 2nd Round: Margin of Victory? (0.1% brackets)

Platform comparison

Active sub-markets

Market context

Peru will hold a second-round presidential runoff on 7 June 2026, pitting the top two candidates from the first round against each other. This market asks traders to predict the winning margin—the percentage-point gap between first and second place in valid votes cast. A YES share pays out if the actual margin falls within a specific bracket (for example, 0–0.1%, 0.1–0.2%, and so forth); a NO share pays out if it falls outside that bracket. The market's 0% crowd probability suggests traders currently see little likelihood of an extremely narrow victory in that particular bracket.

Peru's recent electoral history shows volatile runoff outcomes. In 2021, Pedro Castillo defeated Keiko Fujimori by 1.16 percentage points in a second round marked by legal challenges and polarisation. The 2016 runoff between Fujimori and Kuczynski saw a margin of just 0.24 points, demonstrating that tight finishes are plausible. Turnout patterns, regional voting blocs, and candidate consolidation of first-round supporters all influence final margins. The current 0% probability may reflect either genuine expectation of a decisive victory or limited trading activity in this specific bracket.

Key developments to monitor include the composition of the first-round field (scheduled for April 2026), which determines who advances to the runoff, and any major political or economic shocks between rounds. Campaign messaging, polling trends in the weeks before June, and voter registration figures will shape expectations of margin size. Peruvian electoral authorities' announcements on voter rolls and logistical preparations typically occur in the months preceding the vote.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0.
