Screening Polymarket Insiders is quite challenging—there's too much noise, and often you're just guessing based on empty addresses before understanding what happened afterwards. Particularly, those large profitable positions are one-time addresses with no practical utility.

This time I'm mainly filtering down to low-frequency trading addresses with PnL compressed in the range of tens of thousands to over a hundred thousand dollars to provide observation samples. Sharing 2 Polymarket addresses I've been watching that are suspected Insiders and still active:

Only traded 4 markets, all related to MicroStrategy events, betting on MicroStrategy buying Bitcoin; cumulative PnL exceeds $600K, last active 5 days ago, but currently holds no positions

2. scanner: 0x989b67c86daa5675c2a7d0ee4107d2a38f628ef3
