What is a prediction market signal detector?

A tool that scans social media for sentiment/volume spikes on topics like tariffs or Bitcoin, flagging them before prediction market odds (Polymarket, Kalshi) shift.

How do I build a prediction market signal detector with Node.js?

Grab LunarCrush API key, clone JoeVezzani/prediction-market-signals, npm install, set env var, node index.js. Tracks anomalies in real-time.

Does social sentiment predict Polymarket odds?

Often yes—for events like policy changes. Backtest shows leads of 30-120 minutes, but noise varies by topic.
