Data shows that "insider traders" on Polymarket have profited approximately $143 million since 2024.

PANews reported on March 28th, citing Business Insider, that researchers have discovered that "insider traders" on the prediction market platform Polymarket have accumulated approximately $143 million in profits since 2024. The study, published by scholars from Columbia Law School and the University of Haifa, analyzed over 210,000 suspicious transactions between 2024 and 2026. It cited the account "ricosuave666" as an example, noting that it profited approximately $155,000 by betting on events related to Israel's military action against Iran. The study states that the characteristics of such transactions are similar to some cases involving the alleged exploitation of sensitive information for profit. As this phenomenon has attracted attention, researchers anticipate that regulators will strengthen their scrutiny of prediction markets. Polymarket has already implemented a new policy prohibiting entities from participating in trading using confidential information or manipulated outcomes, but the effectiveness of its implementation remains to be seen.
