Real-Time Sentiment Analysis for Polymarket Trading Bots

Polymarket odds move on information flow, not fundamentals. News breaks, X posts spike, whale wallets move—and prices shift before APIs catch up. Sentiment-powered bots scrape social data in real-time, quantify edge vs market prices, and execute before retail reacts.

2026 edge: News + X sentiment predicts short-term moves better than order flow alone. Bots blending both hit 68% win rates on 15-minute crypto markets.

Why Sentiment Powers Polymarket Edge

Information arbitrage beats price arbitrage:

Market: "BTC > $100K by Mar 31" at 58¢ YES
Your model: 64% true probability from sentiment
Edge: Buy 6¢ EV per share
