Trader Overview
Meet the one Polymarket wallet that turned a serious mid-six-figure deposit into an almost total blowup — and still sits rank #373 with a massive $10M+ in volume. If PnL were a rollercoaster, MonsieurDimanche didn’t just ride it — they built it, then got thrown off.
MonsieurDimanche is a whale-tier positional trader, currently ranked #373 on the [[Polymarket]] leaderboard. They’ve made an eye-watering {totalTrades} trades across 9,202 markets. Their edge? It’s not in win rate (51.2%%) — it’s in sheer, relentless volume and position sizing that borders on the absurd. Avg trade size: ~$152. That’s 12,722 bullets, not rifles.
The strategy is brutal and simple: bet the same event both ways at different times. The all-time best trade? “Will Donald Trump be President of the USA on March 31, 2021?” — bagged +$235,234. The worst trade? Same exact question, same exact market — lost -$233,790. That’s not a hedge, that’s a full exorcism. A buy/sell ratio of 2,500 suggests heavy directional swings, not noise farming.
The edge here isn't prediction accuracy — it’s timing and aggression. Most degans wait for momentum; MonsieurDimanche bought into narrative shifts early, or double-downed late. With an average entry near $0.50, they’re trading binary events like a futures desk — scaling in, scaling out, absorbing massive drawdowns as transaction costs.
Current status: closed all 12,722 positions. No open bets. And with a net deposit loss of ~$1.36M sitting at a -95.87% ROI on deposits, this isn’t a story of genius — it’s a case study in surviving your own volatility. They’ve withdrawn just under $59k, meaning most of those winnings were re-invested and lost. Classic whale tombstone.
