Polymarket Cross-Exchange Arbitrage

Different prediction market platforms attract different trader populations with different biases. This creates real price gaps of 3-10% on the same events. This skill uses pmxt (1,400+ stars, MIT) to scan 9 exchanges simultaneously — Polymarket, Kalshi, Limitless, Smarkets, and more — through a single unified API. It identifies matched events, calculates price discrepancies, and flags arbitrage opportunities. No predictive model needed — pure price discrepancy. Includes WebSocket real-time streaming for instant detection. Best on US political markets where both Polymarket and Kalshi have deep liquidity.
