Filtering Polymarket Insiders is quite challenging, with too much noise and often just guessing based on empty addresses, only to find out gradually afterward. Particularly, those large profitable trades are typically one-time addresses with no practical utility.

This time the main focus is on compressing PnL into the range of tens of thousands to over one hundred thousand dollars in low-frequency trading addresses to provide observation samples. Sharing 2 suspected Insider addresses on Polymarket that have been under observation and remain active:
