A chat with Domer, the #1 trader on Polymarket

Domer, also known as JustKen on the Polymarket leaderboard, is the platform's top all-time trader by volume and profit, with more than 5,000 markets traded and nearly $300m in total volume. He says he moved from online poker and stock trading into prediction markets because they offer the best way he has found to bet on an edge. He describes most of his trades as manual, warns that high liquidity can lead traders to overreach, and expects the US presidential election to be by far Polymarket's largest market.
