Trader Overview
One wallet that turned $198 into $228K active portfolio value in 80+ days — meet the us391 predicted-congressional-event market trader.
This ranking Polymarket whale sits at #985 by total PnL ($154.9K), but their 1,221,146% ROI on deposits is among the wildest on the platform. Us391 is a high-frequency sports + political prediction market operator running 99.5 trades/day across 471 different markets.
The edge is noise collection. Retail buys one yes/no ticket and prays — us391 puts on 1,433 buy trades for every sell, averaging $1,443 per entry at $0.55 midpoint. This isn't directional betting; it's market-making retail micro-orders at scale. A 93.28% win rate across 807 total trades means they're not predicting outcomes — they're pricing spreads better than the order book.
Proof in the extremes: Best trade was cashing $39,242 on ''Will FC Bayern München vs. Paris Saint-Germain FC end in a draw?'' Worst trade tanked $28,474 on ''Will FC Bayern München win on 2026-05-06?''. The $6.1M in gross volume suggests they're running light inventory, rotating capital at 38x net deposit speed.
What separates us391 from 99% of degens isn't luck — it's mechanical discipline. The buy/sell ratio is absurd, meaning they almost never exit early into hype. Every day is 100+ micro-trades, no single thesis, pure edge harvesting. The $198 starting deposit to $132K in withdrawals and $228K still open? That's a 657x capital efficiency on deposited funds you'd need to see to believe.
Currently sitting with 505 open positions ($228K portfolio), net transfers show $132K pulled. Risk level is medium — but that win rate suggests survivorship bias at work. Not everyone survives 284-losses-threshold trades.
