Crypto 15-Minute Cross-Market Arbitrage

This strategy continuously scans the prices of 15-minute Bitcoin markets on Polymarket and Kalshi, identifying price discrepancies for the same underlying outcome. When a price difference exceeds transaction costs and a small profit margin, the bot executes a buy on the cheaper exchange and a sell on the more expensive one, capturing the risk-free spread. The toolkit uses a FastAPI backend for data streaming and a NextJS frontend for monitoring. It is designed as a volume and points farmer as well, potentially earning rewards on top of arbitrage profits. The main risk is execution latency, as these markets are highly efficient and spreads may close quickly. Additionally, there is platform risk, as withdrawal and deposit times may affect the ability to execute both sides of the trade quickly.
