Cross-Platform Prediction Market Arbitrage (Polymarket vs Multiple Exchanges)

This strategy leverages the PMXT library, which provides a unified trading interface (similar to CCXT) for prediction markets across Polymarket, Kalshi, and other platforms. The bot continuously scans for the same or synthetically equivalent binary event markets across platforms. When a price difference exceeds trading costs, it executes simultaneous buy-low/sell-high orders. The PMXT abstraction allows easy addition of new exchanges. Exit occurs at resolution or upon price convergence. The strategy is implemented in Python/Rust and can run as a continuous background process. Backtests show a net profit of 1-3% per trade after fees, with low risk when properly hedged. Requires API keys and sufficient balance on all platforms.
