$580M Polymarket Trade Raises Suspicion of Insider Trading

Roughly 6,200 Brent and West Texas Intermediate futures contracts were traded between 6:49 a.m. and 6:50 a.m. on Monday, fifteen minutes before President Trump announced a five-day pause on strikes on Iranian energy infrastructure. 

The Details: The trade was worth roughly $580 million, according to Bloomberg (Lean Left bias), which also reported the average trading level for the same time period over the previous five days was 700 contracts. About 6,000 contracts were also traded in the S&P 500 moments later, equating over $2 billion in value, according to Bloomberg. The trades have sparked suspicions of insider trading as no major market-related announcements were planned for Monday morning.

Other Trades: On Monday, The Guardian (Left) reported eight newly created Polymarket accounts stand to make nearly $820,000 if the US and Iran agree to a ceasefire by March 31. A previous analysis from New York Times (Lean Left) found over 150 Polymarket accounts had placed bets predicting the US strike on Iran the Friday before it happened. Another case saw a trader make over $436,000 by betting on the US capture of Venezuelan President Nicolas Maduro in January before it was announced the following day. In April, a series of stock trades happened minutes before Trump announced his pause on "Liberation Day" tariffs. Because the accounts are anonymous, It's unclear who is involved in the trades.

Trump Involvement: There is no evidence Trump knew about the trades or that any officials were involved, though Axios (Lean Left) wrote Trump's presidency has "coincided with [lucrative] business and investment activity involving allies, donors and family members." Breitbart (Right) said the White House has "flatly denied" its involvement, but noted Trump's son, Donald Trump Jr., is an advisor to Polymarket and his venture capital firm has invested millions into the business. It quoted an American political consultant who said trades like these "undermine peoples' belief and respect for authority because the information is obviously coming from somewhere."

Push for Regulation: National Desk (Right) reported two different bipartisan bills have been introduced to regulate prediction markets–one to ban them from offering sporting events and another to prohibit members of Congress, the president and members of the executive branch from participating in political prediction markets. CBS News (Lean Left) mentioned Polymarket and Kalshi are tightening their own rules on insider trading.

How the Media Covered It: Outlets on the left generally provided more of the initial coverage of the suspicious trades and hinted at potential Trump ties. Outlets on the right more often covered market reactions and legislative bills aimed at regulating congressional participation in prediction markets. Newsmax (Right) focused on the market's reaction to the ongoing war, but noted the timing of the trade was questionable. Fortune (Center) quoted Nobel Prize-winning economist Paul Krugman calling the trade "treason."
