Cross-Platform Markets

Markets matched across Polymarket and Kalshi. Compare odds and find spreads.

How Cross-Platform Matching Works

  • • AI identifies markets asking about the same real-world event
  • • Only matches with ≥95% confidence are shown
  • • Outcome names are mapped between platforms (e.g., "Trump" ↔ "Donald Trump")
  • • Spread = difference between platform prices for the same outcome
