An AI-driven World Cup prediction system has demonstrated a 91.7% success rate, accurately predicting 11 out of 12 matches. The system, which incorrectly forecasted a draw instead of an England win against Ghana, was developed over two weeks using Claude Code. The system's architecture involves six key components: planning, selecting a technical stack, decoding on-chain data, filtering World Cup data, building a front-end, and testing and deployment. It connects directly to the Polygon blockchain via RPC to access real-time Polymarket data, ensuring a reliable feed of transaction details. The front-end features a customizable dashboard with filters for whale signals and World Cup-specific data, enhancing user experience and operational efficiency.
