Polymarket faces a damning investigation into insider trading as dozens of users placed suspiciously well-timed bets. A New York Times investigation uncovered more than 80 suspicious Polymarket users betting on everything from Iran military strikes to crypto markets, raising urgent questions about how government insiders exploit prediction markets.
🔥 Quick Facts
- NYT Investigation: More than 80 Polymarket users with suspicious betting patterns, including 38 accounts showing well-timed activity.
- Iran Bets: 150+ accounts correctly predicted US-Iran military strikes, collectively betting $855,000 in February 2026.
- Record Profits: Six accounts alone made approximately $1.2 million by predicting the US strike on Iran by February 28.
- Large Trader: One anonymous NYC-based trader accumulated nearly $1 million in profits since 2024 using remarkably accurate geopolitical predictions.
The Investigation Reveals Dozens of Suspicious Trading Patterns
The New York Times investigation, published May 13, discovered that more than 80 Polymarket accounts placed bets exhibiting classic insider trading characteristics. Of these, 38 accounts showed patterns suggesting access to non-public information. The bets spanned geopolitical events including the Iran conflict, ceasefire negotiations, and even weather-related markets, each timed suspiciously close to major announcements.
According to the investigation, traders demonstrated an almost superhuman ability to predict sudden military actions, regime changes, and diplomatic moves. Federal law explicitly prohibits using classified information for prediction market trading, yet enforcement has remained sparse until recently.

Iran Military Bets and Million-Dollar Windfalls
The most striking evidence involves bets placed on Iran-related events. In February 2026, when the US military struck Iran, more than 150 newly created Polymarket accounts had correctly predicted the outcome hours earlier. These accounts collectively wagered $855,000, with 16 individual accounts each pocketing more than $100,000 in profits.
Six particularly successful accounts made approximately $1.2 million by betting on the exact timing of the US strike. One anonymous trader from New York City has accumulated nearly $1 million in total winnings across dozens of eerily prescient geopolitical bets since 2024, according to CNN’s investigation.
Polymarket’s Response and Regulatory Pressure
| Timeline | Action Taken |
| March 2026 | Polymarket tightens trading rules following initial scrutiny |
| April 2026 | US soldier arrested for trading on classified military information |
| May 1, 2026 | Polymarket announces partnership with Chainalysis for on-chain monitoring |
| May 13, 2026 | New York Times publishes major investigation revealing 80+ suspicious accounts |
Polymarket launched damage control by partnering with Chainalysis Inc., a blockchain analytics firm. The platform also tightened its trading rules and announced enhanced market integrity tools. However, critics contend these measures arrive too late and that the platform’s fundamental design, which offers zero KYC requirements and unlimited wallets, enables insider abuse.
“Under federal law and agency regulations, insider trading on prediction markets is prohibited, though what qualifies as an offense is a complex question that regulators are still grappling with.”

The Broader Geopolitical Betting Phenomenon
The investigation uncovered suspicious betting not just on Iran conflict outcomes but also on Venezuela regime changes, Paris weather spikes, and other events requiring access to government operations. Traders displayed uncanny timing predicting Israeli strikes in October 2024 and subsequent US military actions. One pattern stands out: bets placed hours before official announcements, yet somehow capturing the exact outcomes.
The White House actually warned executive branch staff in March against using classified information to place Polymarket bets, indicating senior government awareness of the problem. Yet the warnings apparently came too late for at least one US Army soldier, who was arrested in April for trafficking in classified information on the Venezuelan coup.
Will Regulators Finally Crack Down on Prediction Markets?
The CFTC and Department of Justice face mounting pressure from lawmakers on Capitol Hill demanding stricter oversight. Yet major questions persist. How many more insiders remain undetected? Can blockchain analytics truly catch sophisticated operatives? And why did Polymarket continue operating with virtually no safeguards despite months of mounting evidence?
The investigation suggests this problem extends across prediction markets broadly. Fellow platform Kalshi also caught suspected insiders, but both exchanges argue legitimate prediction markets serve important price-discovery functions. Economists defend the concept, yet clearly the current systems lack adequate guardrails against abuse by government officials extracting millions in windfalls from retail traders.
