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

Market context

Peru will hold a presidential runoff on 7 June 2026 between its top two candidates from the first round. This market brackets the winning margin into 0.1 percentage-point bands, measuring the absolute gap in valid votes between first and second place. The runoff format itself—triggered when no candidate secures 50 per cent in the first round—has become Peru's standard since 2016, following constitutional reforms that tightened the threshold for outright victory.

Historical runoff margins in Peru show considerable variance. The 2016 second round between Pedro Pablo Kuczynski and Keiko Fujimori resolved with a 0.24 percentage-point margin, one of the tightest on record. By contrast, the 2021 runoff between Pedro Castillo and Fujimori produced a 1.96 percentage-point spread. These precedents suggest that whilst landslide outcomes remain possible, competitive races clustering between 0.5 and 2.0 percentage points are common, making narrow-bracket outcomes plausible rather than exceptional.

Traders should monitor first-round results scheduled for April 2026, which will determine the two finalists and their respective vote shares—a critical baseline for assessing runoff momentum. Campaign messaging, regional turnout patterns, and any shifts in voter coalitions between rounds will shape the final margin. Polling volatility in Peru has historically been pronounced; institutional instability and economic conditions in the months leading to June will merit close attention, as these factors have previously shifted runoff dynamics substantially from first-round positioning.

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.
