Polymarket user suspected of insider trading, mysterious account profits millions of dollars

According to Mars Finance, as reported by Decrypt, Polymarket announced the results of the 2025 Google Search Trends yesterday, with the little-known singer d4vd unexpectedly winning. A user with the code name 0xafEe accurately bet on all major candidates and earned $1.15 million, sparking suspicions of insider trading. This user not only correctly predicted d4vd’s victory (with only a 0.2% chance of winning at the time), but also accurately predicted the defeat of popular candidates such as Pope Leo XIV and Trump. Afterward, the user immediately changed their nickname, which added to the suspicion. Polymarket veteran user Car questioned on the X platform: this is basically an internal employee making extra money. However, some believe that insider trading is a feature, not a flaw, of such platforms, making prediction markets closer to real probabilities.
