Polymarket Bets on Iran Strikes Spark Insider Trading Concerns

Trading on the prediction market Polymarket surrounding potential U.S. Military action against Iran has surged, with over $529 million wagered, raising concerns about potential insider trading. Several newly created accounts made remarkably accurate bets on the timing of the February 28, 2026, strikes, prompting scrutiny from lawmakers and regulators.

Suspiciously Timed Bets Yield $1.2 Million Profit

Blockchain analysis by Bubblemaps SA revealed that six accounts, created in January 2026, focused exclusively on betting on the timing of a U.S. Attack on Iran. These accounts collectively profited approximately $1.2 million from the correctly predicted February 28 strike, with some bets placed just hours before the attacks commenced [1].

One account, “Magamyman,” reportedly made over $500,000 on the U.S. Attack, with its first trade executed just over an hour before the news became public [4].

Polymarket and Past Scrutiny

This isn’t the first time Polymarket has faced questions about potentially illicit activity. Previously, an anonymous account reportedly earned over $400,000 by betting on a potential U.S. Intervention in Venezuela and the ousting of President Nicolás Maduro [2]. This earlier incident drew criticism from U.S. Lawmakers.

Lawmaker Calls for Regulation

Democratic Senator Chris Murphy has voiced concerns about the legality of such practices, stating that profiting from geopolitical events raises serious ethical and legal questions. He announced plans to introduce legislation to ban such activities [2].

Record Trading Volume and Anonymity Concerns

The U.S.-Iran conflict has driven record trading volume on Polymarket, with one contract predicting the timing of a U.S. Attack reaching nearly $90 million in wagers [3]. Bubblemaps CEO Nicolas Vaiman noted that prediction markets allow individuals with advance information to potentially profit significantly from geopolitical events.

The anonymity afforded by Polymarket, which allows users to trade using cryptocurrencies with only a crypto wallet required, complicates efforts to trace and investigate potential insider trading [2].

Polymarket’s Role in Geopolitical Forecasting

Polymarket positions itself as a platform for forecasting geopolitical events, aiming to harness the “wisdom of the crowd.” While, the recent events have raised questions about the integrity of the market and the potential for exploitation [1].
