In the world of prediction markets, a new legend has emerged. Meet "fengdubiying," who stunned the Polymarket community by raking in a staggering $3.18 million in just one month. Specializing in sports betting, particularly esports like League of Legends (LoL) and the NBA, his success is no fluke but a result of a strategic aggressiveness and sharp expertise that captivates thousands of bettors.
Analyzing their profile reveals a trader who joined Polymarket in October 2025 and quickly established themselves as one of the best traders on prediction markets. Their strategy is clear: massive, concentrated bets on markets they know inside out.
A single one of their winning trades netted over $818,000. Their biggest successes come from League of Legends matches, where they’ve wagered hundreds of thousands of dollars on teams like Gen.G, T1, or G2 Esports. For instance, a single bet on a match between Gen.G and Hanwha Life Esports earned nearly $440,000.
What’s striking is their ability to identify favorites and bet big, transforming their deep knowledge of the game and teams into massive profits. They don’t just bet on the winner, but on precise scenarios, demonstrating analysis that goes far beyond simple luck.
Fengdubiying’s success might seem out of reach, but tools are emerging that allow bettors to learn from the best. For those wanting to dive into LoL markets, TradeFox has developed a “Lightning Sport Mode”, a simplified interface that lets you bet on matches in just a few clicks, without getting lost in Polymarket’s complex interface.
