Counted from Polymarket’s settled position records — not modelled or estimated. Win rate counts positions, not dollars: a trader can win less than half their positions and still be well ahead if the winners are larger, which is common here.

Trades under $100 are recorded but not shown, here or anywhere else in Alpha. This list is filtered by size only. The live feed applies more — it shows buys, so the 33 sells here will not appear there, and it opens on a higher size than this floor.
