15-Minute BTC Arbitrage Between Polymarket and Kalshi

This strategy monitors price discrepancies between the same 15-minute BTC up/down markets listed on both Polymarket and Kalshi. When a significant price gap appears, the bot simultaneously buys the cheaper side on one platform and sells the equivalent on the other, locking in a risk-free profit. Entry is triggered by a configurable spread threshold (e.g., >2%), and exit occurs once the prices converge or at market expiry. The bot is implemented in Rust for low-latency execution and supports both BTC and SOL 15-minute markets. Results from backtesting show consistent small-margin captures per trade, compounded over many cycles. Deployment requires API keys for both exchanges and a hosted server for 24/7 uptime.
