Trader Overview
Wallet 0x9ae8e924d922c02d6976f304c67fa2fdf691c2a8 deposited $545k into Polymarket, ran 1,005 trades across 988 markets, and somehow ended down $26.5k — the math here is what kills you.
Meet cddb, a Polymarket whale who trades like a bot on espresso. Rank 2.4M. 25 trades per day, 47.5% win rate, -12.47% ROI on deposits. This is the profile of someone who understood prediction markets intellectually but got eaten alive by execution.
The volume tells the story: $6.97M in total trades, $1,393 average ticket size, 11.8x more buys than sells. He positions like he's scalping noise instead of predicting outcomes. His best trade hit $20,968 on Brisbane Roar FC vs. Wellington Phoenix FC - More Markets (2026-03-21), but his worst? Down $21,278 on VfB Stuttgart vs. FC Porto. Swings that big scream panic hedging or chasing losses.
Here's the brutal edge breakdown: there is none. cddb has the capital to absorb noise but not the discipline to stop taking it. The math is simple — at 47.5% win rate with medium risk and that trade frequency, you're fighting the spread plus your own decision fatigue. Buy/sell ratio of 11.8 suggests he's reactive, not strategic. Real prediction market traders average 3-988 markets. He touches 988. That's not diversification, that's distraction.
The deposits-to-withdrawals gap ($545k in, $475k out) shows the classic whale mistake: swing-trading prediction markets like spot trading on a CEX. Portfolio value now sits at $1,283. Two open positions remain. Whether he's waiting for a reversal or just hasn't closed out yet, the damage is locked.
This is the Polymarket whale profile that matters most to study — not because he's crushing, but because he proves capital alone doesn't survive markets that reward signal over noise. Track his remaining positions on Predicts.guru to see if the Polymarket whale trader can actually close profitably.
