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

Platform comparison

Active sub-markets

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 in 0.1 percentage-point increments, measuring the absolute difference in valid votes between first and second place. The current 0% probability across major platforms suggests minimal trading activity or consensus difficulty in forecasting such granular outcome bands.

Peruvian runoffs have historically produced decisive victories. The 2016 second round saw Pedro Pablo Kuczynski defeat Keiko Fujimori by 0.24 percentage points—an exceptionally tight result that nonetheless resolved cleanly. The 2021 runoff between Pedro Castillo and Fujimori yielded a 1.16-point margin. These precedents indicate that whilst blowouts exceeding 5 points are possible, competitive races clustering between 0.5 and 3 points remain plausible. The current zero probability likely reflects sparse liquidity rather than genuine forecasting consensus; Polymarket and Kalshi both show minimal order depth on this bracket structure, whilst Betfair's decimal-odds presentation may obscure the granularity traders face here.

Key catalysts include the first-round results (scheduled for April 2026), which will identify the runoff participants and establish baseline polling differentials. Campaign messaging, economic conditions between April and June, and any electoral irregularities or legal challenges could shift momentum. Traders monitoring Peruvian news sources and polling aggregators should track whether first-round margins suggest a competitive or lopsided second-round dynamic. Fee structures vary meaningfully: Kalshi's flat commission differs from Polymarket's AMM spreads and Betfair's commission tiers, affecting profitability on tight margin predictions where percentage-point differences matter substantially.
