What is a prediction market whale?

A whale is a wallet placing unusually large trades on a prediction market such as Polymarket or Kalshi. Because these markets settle on real-world outcomes, tracking where the biggest and most accurate wallets are putting their money can surface smart-money movement before it shows up in traditional sportsbook lines.

How is the signal score calculated?

Each trade earns a signal score from the trading wallet's track record — win rate, number of resolved sports outcomes, and lifetime profit — combined with the size of the trade. The score shown for a bet is the average across every whale trade on it, weighted by how much money each wallet put down, so a large position from a proven wallet moves it more than a small one. Scores of 75 or above are labeled Strong, 60 to 74 Moderate, and below 60 Weak.
