prediction-markets

Another cross-platform arbitrage scanner, but supporting four venues: Kalshi, Polymarket, Smarkets, and Opinion Trade. The addition of Smarkets (UK-based, fiat currency) and Opinion Trade (still in beta) broadens the scope. The 178KB repo is compact, likely containing a few well-structured scripts for fetching order books and comparing odds across these platforms. The username 'turkeygobbler420' is less professional but doesn't compromise the code. This tool is a useful reference for how to build integrations with multiple prediction market APIs - each has different authentication, rate limits, and data formats (Polymarket uses CLOB with WebSockets, Kalshi has REST, Smarkets uses a different API). The scanner's purpose is identifying mispricings before they converge, which is the classic arbitrage opportunity. Given its small size, code quality is probably decent but not heavily documented. No stars suggests little community validation. For live trading, speed is critical - this would need to be quite efficient to be useful. As a learning tool or starting point for a custom arbitrage bot, it's valuable. Malware risk is low given the small, data-focused footprint. It's a niche but potentially useful find for multi-venue arbitrage enthusiasts.
