Prediction markets moved before currencies in three elections

Key takeaways

1. In Romania, Peru and Japan, prediction markets priced a new likely winner before the currency's largest move.
2. Romania: Simion rose from 32% to 52% during the first-round count, and the leu then fell 3.7% against the dollar over five sessions.
3. Peru: Fujimori passed Lopez Aliaga eight days before the vote; the sol moved less than 0.1% by April 9 and strengthened 2.4% by April 13.
4. Japan: Takaichi's price rose from 15% to 98% over a weekend, and the yen weakened 1.6% over the next five sessions.

Election markets can trade through the moments when political risk is being decided. Currency markets keep hours, and the currency move tied to an election can take days to finish.

This report follows three elections where Polymarket and Kalshi priced a new likely winner before the related currency made its larger move.

In Romania, prediction markets shifted toward George Simion, the hard-right and EU-sceptic challenger, during the first-round vote count on May 4, 2025, before the leu weakened. In Peru, Keiko Fujimori became the prediction-market favorite on April 4, 2026, eight days before the vote, while the sol's larger move came after the count confirmed the result. In Japan, Sanae Takaichi became the likely next prime minister over the weekend of October 4, 2025, while yen trading was closed.

Three elections cannot establish a general rule, but in each of them prediction markets priced the political change first and currency markets took days to finish adjusting.

Figures come from Allium data across Polymarket and Kalshi, queried in August 2026, with currency levels from public benchmark data.
