Trader overview
SemyonMarmeladov Polymarket trader dropped $2.2M net deposits, hit a $314K single trade win on FC Bayern München vs. FC Augsburg, runs a 68.7% Polymarket win rate across 1,700 trades — then somehow sits down -56% ROI on deposits. This is the whale who prints on individual picks but bleeds on the aggregate.
SemyonMarmeladov ranks #122 on the Polymarket leaderboard with $808K lifetime PnL. Whale tier, low risk profile, 2,246 markets traded. The math screams specialist: 7.1 trades per day, $11.8K average position size, 24:1 buy-to-sell ratio (he's a directional accumulator, not a scalper). He's not noise hunting. He's conviction stacking.
The edge is surgical category depth. 0 open positions right now across different verticals means he's not chasing headlines — he's farming micro-inefficiencies in niche prediction spaces where retail hasn't looked yet. Win rate of 68.7% on a Polymarket whale sits well above average. That's not luck. That's pattern recognition in the long tail of markets most people ignore. He enters early, sizes smart, and exits when thesis confirms.
But here's the gut-punch: $2.42M in total deposits, $808K lifetime PnL, -56% ROI. The single worst trade bled $150K on Columbia Lions vs. Brown Bears. That's not a blip. His portfolio sits at $840K, meaning he's underwater relative to dry powder. The Polymarket PnL looks glossy until you compare it to cash in. A 100% win rate doesn't matter if position sizing or conviction timing is off — and with a max loss that deep, something twitched.
Current state: 9 positions live, low risk flagged. He's not derisking, not panic-selling. That's either discipline or denial. The daily 7.1 trade rate suggests he's still grinding, still believing in the specialty edge. Real edge doesn't disappear in two weeks. But -56% ROI on $2.4M tells you: even 100% win rate prediction markets don't feel like free money when you're the whale holding the bag on the wrong side of conviction. Not everyone who beats the prediction market odds actually beats the clock.
