Prediction markets were supposed to be the wisdom of crowds, distilled into probabilities and priced in real time. But when a cluster of anonymous wallets starts winning 98% of their bets on Iranian war policy, the crowd starts looking less wise and more like someone who read the answer key.
Polymarket’s geopolitics category has ballooned to roughly $5 billion in total volume year-to-date through mid-June 2026, with Iran-related contracts alone exceeding $2 billion in the first four months of the year. April was the peak month, with the geopolitics category hitting over $1.5 billion in volume.
The numbers behind the boom
Iran-related bets on Polymarket averaged 8.4% daily volume growth in March alone. A market titled “US strikes Iran by…?” attracted over $529 million in volume. A separate contract centered on a prospective US-Iran peace deal crossed $479 million by mid-June.
The wallets that win too much
According to a May 2026 analysis by Bubblemaps, nine interconnected anonymous wallets achieved a 98% win rate on Iran war policy bets, collectively pocketing $2.4 million in profits. The wallets were linked through on-chain transaction patterns, suggesting coordinated activity rather than nine separate traders who all happened to be preternaturally gifted.
Analytics firm Polysights flagged approximately $45 million in suspicious trades tied to Iran-related outcomes, making the geopolitics category the primary source of anomalous activity on the entire platform.
Polymarket has responded by referring nearly 100 wallets to law enforcement for potential insider trading. The platform has also tightened its rules around trades based on stolen or confidential information.
Regulatory pressure builds
The insider trading concerns come at a particularly sensitive moment for Polymarket. The platform has faced increasing scrutiny from both Congress and the CFTC, which has long grappled with how to classify and regulate prediction markets.
Polymarket’s decision to refer wallets to law enforcement suggests the platform believes insider trading concerns apply to prediction markets, or at least wants to be on the right side of the question when regulators come knocking.
What this means for traders and the broader market
For traders currently active in these markets, the $45 million in flagged suspicious activity represents a tangible cost. Every time an information-advantaged trader takes the other side of a bet, the uninformed counterparty is systematically overpaying.
The $2.4 million those nine wallets extracted is a rounding error compared to the $5 billion in total geopolitics volume. But with nearly 100 wallets referred to law enforcement and tens of millions in suspicious trades identified, questions of market integrity are being stress-tested in real time.
