About

Signal is a real-time prediction market intelligence engine that aggregates Polymarket data, enriches it with macro indicators (FRED), asset prices (Yahoo Finance), and public attention (Google Trends), then classifies markets using GPT-4o-mini into six categories (Crypto, Economy, Politics, Geopolitics, Sports, Tech) and exposes curated insights through a FastAPI REST API. The pipeline fetches 200+ active prediction markets, categorizes them, filters for signal-relevant markets with >$500 volume, deeply enriches 12 high-signal markets with real-world context, computes composite trending scores, and generates a global sentiment overview—all serving as the data backbone for the Signal web app's markets feed, dashboard, and trending widgets.
