Polymarket's US-Iran invasion contract swings from 68% to 14-28% amid diplomacy push

Published Jun 30, 2026

Polymarket's US-Iran invasion contract spiked to 68% odds before falling to a 14-28% range as diplomatic efforts intensified. The market has generated $500 million in trading volume. The volatility has also drawn insider trading concerns from observers watching for information asymmetries around geopolitical developments.

High-volume geopolitical markets on Polymarket are becoming real-time barometers of conflict risk, but the insider trading concerns show regulators and platforms still lack clear frameworks for policing information advantages in event contracts.
