Polymarket sees 'psychic' account cluster: 41 out of 42 bets correct, all betting on KPMG audit firm.

BlockBeats news, September 12, according to WSJ, a group of 19 interconnected Polymarket accounts concentrated bets over the past few months on the financial reports of public companies audited by KPMG, with 41 out of 42 trades profitable, achieving a 98% win rate and cumulative profits of approximately $22,000.

Bubblemaps analysis found that these accounts had bet on 18 KPMG clients, including Wells Fargo, Home Depot, DoorDash, and General Mills, with funds flowing in a complex manner among the 19 accounts, suspected to be controlled by the same person or team.

It is worth noting that this investigation coincides with U.S. law enforcement probing a KPMG employee suspected of insider trading using Polymarket. The Wall Street Journal previously reported that the employee is under investigation for betting on whether public companies' quarterly earnings would exceed market expectations. It is currently unclear whether the account cluster discovered this time is related to the employee, and Bubblemaps also emphasized that the analysis itself cannot prove the existence of insider trading.

KPMG stated it has "zero tolerance" for trading using non-public client information and has strengthened related monitoring. As the prediction market scale rapidly expands, the risk of insider trading on Polymarket is drawing continuous attention from regulators and law enforcement agencies.
