Suspected insider accounts net $2.4 million on Polymarket Iran war bets with 98% win rate, firm finds

Key Points:

• Nine linked Polymarket accounts have earned over $2.4 million by betting on specific U.S. military actions, raising suspicions of insider trading according to data analytics firm Bubblemaps. These accounts had a 98% win rate on more than 80 bets related to key events in the Iran conflict.
• Insider trading concerns have increased as prediction markets like Polymarket, which allow public betting on future events including military outcomes, grow in popularity. The U.S. Army recently indicted a soldier for allegedly using classified information to win bets on a Venezuelan operation.
• Experts warn that many individuals involved in military operations, including government officials and family members, could access nonpublic information, creating numerous potential insiders. Investigations suggest systemic insider trading on military-related bets, with some bettors winning despite low odds.
• Suspicious trading activity has also been observed in regulated commodities markets, such as a large oil futures bet just before a public announcement about U.S.-Iran talks that caused oil prices to plummet, prompting federal probes.
• Polymarket states it uses AI and blockchain forensics to detect and act on suspicious trades, cooperating with law enforcement, but oversight challenges remain as insider trading on prediction markets could pose national security risks by revealing sensitive information to adversaries.
