Someone took a $10 principal and, by betting on the weather, turned it into $41,000 on Polymarket. This isn’t a joke; it’s a real case, with returns up 4,100x.

The market he trades the most falls into one category: whether the highest temperature in Taipei or Shenzhen will hit a certain threshold. Just in this type of trade, he’s done nearly 2,000 orders.

The logic is simple—when the market price temporarily deviates from the real probabilities, he confidently buys “yes” or “no.” One or two trades don’t show much, but with hundreds or thousands of transactions, the statistical edge gradually accumulates.

This person really has ideas. If you want to follow along, you can try the Polycop tool:
