Polymarket military insider trading research

The research heightens regulatory and national security concerns around prediction markets, potentially leading to stricter oversight and reduced investor confidence in platforms like Polymarket. This could impact trading volumes and valuations of prediction market operators, while defense and intelligence sectors may face increased scrutiny over information leaks.
The Anti-Corruption Data Collective (ACDC) published research on August 20, 2026, revealing that more than 150 wallets on Polymarket International may have traded on inside U.S. military information. These wallets, dubbed 'Orcas,' placed highly successful long-shot bets on military and defense markets, collectively earning $8 million with an average win rate of 97.2%. The research also found that these trades attracted copycat bets from 'Whales' and automated bots, potentially amplifying insider signals and making them observable to foreign adversaries. This comes amid increased scrutiny of prediction markets following the case of 2026 United States intervention in Venezuela, a U.S. soldier charged with using classified information to bet on the removal of Venezuela's President Nicolás Maduro. Polymarket has referred dozens of wallets to authorities, and the United States — United States Commodity Futures Trading Commission has brought charges in at least three cases. ACDC recommends mandatory identity verification and bans on markets where non-public information is most actionable.
