Prediction Markets Leaderboard

Success in prediction markets isn't just about luck—it’s about information. The Action Network Leaderboard tracks the world’s top event contract traders across Polymarket and Kalshi, giving you a transparent look at who is consistently beating the market.

How to Use This Page

Use the filters above to deep-dive into trader performance:

  • Performance Metrics: Sort by PnL (Profit & Loss) to see the biggest winners, or by Trading Volume to identify the highest-activity "whales."
  • Timeframes: Toggle between Today, Weekly, Monthly, or All-Time to separate short-term heaters from long-term experts.
  • Market Categories: Filter by specific interests such as Politics, Sports, Economics, Mentions, or Weather to find specialists in those fields.

Reading the Data: PnL is color-coded for quick scanning—Green indicates the trader is currently in the profit, while Red indicates a loss for the selected period.
