poly-kalshi-arb

This bot targets a classic arbitrage opportunity: price discrepancies between two prediction market platforms—Kalshi and Polymarket—for the same or equivalent events. The strategy is straightforward: simultaneously buy on the cheaper platform and sell on the more expensive one, capturing the spread. The repository is well-organized with clear setup instructions, configuration files, and trade execution logic. Code quality is decent for a hobbyist project, with reasonable modularity and error handling. No malware concerns were identified; the code is transparent and does not contain obfuscated scripts or suspicious network calls. The developer has included a sample configuration and logging, which are good practices. This bot is suitable for intermediate traders who understand the risks of cross-exchange arbitrage (execution speed, settlement differences, API rate limits). The market structures of Polymarket and Kalshi differ slightly (e.g., resolution sources), so careful mapping of events is required. The 5-star rating and 2 forks suggest modest but positive community interest. It is worth cloning for learning and potential profit, but users should start with small amounts and monitor for execution slippage.
