Prediction Markets Face Scrutiny After Profitable Bets on U.S.-Israel Strike on Iran

Washington D.C. – Prediction markets are under intense scrutiny following reports of substantial profits made by traders who accurately predicted the U.S. And Israel’s recent strikes on Iran. Lawmakers and regulators are raising concerns about potential insider trading and the lack of oversight in these increasingly popular online platforms.

Lawmaker Outcry and Calls for Regulation

Multiple Democratic lawmakers have criticized the limited regulation of online betting platforms, alleging that individuals with potential advance knowledge profited significantly from predicting the military action. Senator Chris Murphy (D-CT), a member of the Senate Foreign Relations Committee, stated on X (formerly Twitter), “It’s insane this is legal. People around Trump are profiting off war and death.” He announced plans to introduce legislation to ban such practices. Source

Representative Mike Levin (D-CA) also voiced concerns, highlighting Donald Trump Jr.’s connection to Polymarket, a prominent prediction market platform. Levin noted that Trump Jr.’s firm invested “double-digit millions” into Polymarket last year. Source

Six Democratic senators previously urged the Commodity Futures Trading Commission (CFTC) to increase oversight of prediction markets, particularly regarding contracts related to wars, assassinations, and terrorism, which are prohibited under federal law. Source

Profits and Suspicious Trading Activity

Blockchain analytics firm Bubblemaps identified at least six accounts on Polymarket as “suspected insiders” who profited from bets placed shortly before the strikes occurred. These accounts collectively made approximately $1 million by betting on the timing of the U.S. Attack on Iran. Source One account, named Magamyman, reportedly earned over $515,000 on an $87,000 bet that the U.S. Would strike Iran by February 28, 2026. Source

Similar activity was observed on Kalshi, another prediction market platform, prompting calls for increased scrutiny from elected officials and gaming regulators. Source

Polymarket’s Response

In a statement on its website, Polymarket defended the value of prediction markets, stating their purpose is “to harness the wisdom of the crowd to create accurate, unbiased forecasts for the most important events to society.” The platform acknowledged the sensitivity of predictions surrounding military activity and emphasized its role in providing information during “gut-wrenching times.” Source

The Market Context

As of Sunday, March 1, 2026, Polymarket’s market on whether the U.S. Or Israel would strike Iran by December 31, 2026, shows a significant volume of trading. The market had a total volume of $19,807,823.

Looking Ahead

The recent events have intensified the debate surrounding the regulation of prediction markets. The CFTC, under the leadership of Chair Mike Selig, has been seeking to assert federal jurisdiction over these markets, challenging state-level regulation. Further legal challenges and legislative action are anticipated as lawmakers grapple with balancing the potential benefits of prediction markets with the risks of illicit activity and the ethical concerns raised by profiting from geopolitical events.
