Polys
Prediction market intelligence — real-time odds, arbitrage, and whale tracking.
About the project
A full-stack prediction market intelligence platform built with Next.js 16 App Router. Polys pulls live data from Polymarket and Kalshi, normalizes it into a unified market type, and delivers real-time odds updates via the Polymarket CLOB WebSocket — falling back to REST polling when the stream is unavailable.
The platform includes a cross-platform arbitrage scanner using Jaccard similarity matching, a whale wallet tracker with live trade feeds, email alerts with a cron-driven check engine, and four distinct Gemini AI surfaces: per-market analysis, dashboard intelligence, watchlist one-liners, and smart suggestions. Auth, watchlists, alerts, and notifications are all persisted in Supabase with RLS.
Key Highlights
- Polymarket CLOB WebSocket with REST fallback
