Polymarket Traders Win 98% of Bets on KPMG-Audited Companies

A cluster of Polymarket traders made 41 out of 42 winning bets on earnings results from companies audited by KPMG, according to a Wall Street Journal report. The trades ran for several months, starting in November 2025 and returning about $22,000.

Bubblemaps, a blockchain data firm, identified 19 connected accounts with a 98% win rate on the KPMG-audited companies. These included Home Depot, DoorDash, General Mills, and Wells Fargo, among others.

KPMG has stated that it has 'zero tolerance' for employees using nonpublic client information, including in prediction markets. However, no employee has been charged.
