Six months from $1,500 to $6 million — this number sounds crazy, but it's not about luck.

Polymarket, a prediction market platform, has tens of thousands of trading pairs, but one individual focuses on a single direction: sports event predictions. User kch123 is therefore recognized within the industry as the top sports trader.

Take a look at this track record:
Total profit of $6.1 million
Participated in 1,437 trades
Largest single profit of $480,000
Current position size of $900,000

What is the underlying logic behind this? No bots involved, no complicated tricks—just a repeatedly refined trading edge: a deep understanding of the probabilities of sports events.

In prediction markets, this is what’s most worth studying: not chasing hot trends, not going all-in on a single project, but deeply cultivating a vertical niche and turning probability advantages into sustained profits. Most traders do everything and end up doing nothing well; this trader’s strategy is exactly the opposite—focusing on one thing and doing it to perfection.

This also sheds light on a phenomenon: whether in traditional trading or crypto markets, focus often outweighs participation.
