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

Platform comparison

Active sub-markets

Market context

Peru's second-round presidential election on 6 June 2026 will determine the margin between the top two finalists, with Polymarket currently pricing all 0.1% bracket outcomes at near-zero probability across the board. The contract resolves on the absolute percentage-point difference in valid votes cast, meaning a 5.3-point victory and a 5.4-point victory occupy separate brackets. This granular segmentation creates substantial liquidity fragmentation, which explains why conditional tokens on Polygon are trading with minimal depth despite the election's significance for Peru's political trajectory.

Peruvian runoff elections have historically produced variable margins. The 2016 second round saw Pedro Pablo Kuczynski defeat Keiko Fujimori by 0.24 percentage points—an exceptionally tight result that shaped expectations for future contests. By contrast, the 2021 runoff between Pedro Castillo and Fujimori produced a 1.97-point margin. These precedents suggest traders should calibrate expectations around whether Peru's political polarisation will narrow or widen the gap between finalists, though first-round results in April 2026 will provide essential data for recalibrating bracket probabilities.

Key catalysts include the first-round election on 5 April 2026, which determines the two candidates advancing to the runoff, and any interim polling released between rounds. Political instability, judicial developments affecting candidate eligibility, or shifts in voter turnout patterns could materially alter margin expectations. Traders should monitor Peru's electoral authority (ONPE) announcements regarding voting procedures and any legal challenges to candidate registration that might affect campaign momentum in the two-month window before the runoff.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
