Prediction markets have found their killer app, and it’s geopolitical conflict. Polymarket, the Polygon-based betting platform that rose to fame during the 2024 US election cycle, has seen its geopolitics category explode in 2026, driven almost entirely by users wagering on US military actions involving Iran.
The numbers are staggering. Iran-related bets on Polymarket surpassed $2 billion in total volume within the first four months of 2026 alone. A single flagship contract, titled “US strikes Iran by…?”, generated over $529 million in trading volume by early March. And by mid-June, the platform hosted more than 170 active markets specifically tied to Iran, covering everything from military strikes to regime change to diplomatic outcomes.
The insider trading problem
An investigation surfaced in May 2026 centering on nine interlinked anonymous accounts that reportedly earned $2.4 million in profits on Iran-related bets. Their win rate was 98%, according to Bubblemaps analysis.
The accounts allegedly placed highly strategic bets just minutes before major announcements concerning military strikes or political developments, including potential actions targeting Iranian Supreme Leader Ali Khamenei. This pattern triggered congressional probes in May 2026, with lawmakers demanding answers about how Polymarket handles sensitive geopolitical contracts and whether the platform has adequate safeguards against traders acting on non-public government intelligence.
