Unnamed traders placed roughly $7 billion [1] in well-timed oil and prediction-market bets ahead of geopolitical news involving Iran.
These trades have sparked concerns that individuals used confidential government information to profit from the volatility of global energy markets. Lawmakers and analysts said they are calling for congressional investigations into potential insider trading based on the timing of the transactions.
The activity occurred during March and April 2026 [3]. Traders placed sell orders and bets on global oil futures exchanges, including Brent, WTI, gasoline, and diesel, as well as the U.S.-based prediction platform Polymarket [1, 3]. The trades preceded critical announcements regarding cease-fire agreements, the delay of military strikes, and the reopening of the Strait of Hormuz [3].
Reporting shows that some trading accounts achieved win rates as high as 93% [1]. On the Polymarket platform alone, dozens of bets related to the Iran war were identified [2]. The precision of these moves suggests the traders had advance knowledge of diplomatic or military developments that would shift oil prices.
Critics said the scale of the profits indicates a highly organized effort. Because the bets aligned so closely with non-public government decisions, officials are seeking to determine if the leak originated within the U.S. government or from allied intelligence agencies [1, 4].
While some reports have linked these trades to a specific military operation, other sources described the events more broadly as geopolitical developments surrounding the Iran war [1, 5]. The focus of the current inquiry remains on the flow of information that allowed these accounts to anticipate market shifts with such accuracy.
“Some trading accounts achieved win rates as high as 93%”
The intersection of traditional futures markets and decentralized prediction platforms like Polymarket has created new vulnerabilities for information leaks. If these trades are proven to be based on insider government data, it could lead to stricter regulations on prediction markets and a broader crackdown on how sensitive diplomatic timelines are secured to prevent market manipulation.
