Polymarket News Sentiment Bot
LLM-powered bot that monitors news, analyzes with Claude, and trades Polymarket.
Quick Start
cd /Users/tori/Documents/Repos/polymarket-tools/news-sentiment
source venv/bin/activate
python main.py
Setup
Uses Chinchilla Claude proxy - no API key needed!
Optional .env settings:
TWITTER_BEARER_TOKEN=... # For Twitter monitoring
POLYMARKET_*=... # For live trading
How It Works
- Fetches news from RSS feeds (Reuters, BBC, NYT)
- Sends each headline to Claude with active markets
- Claude determines if news affects any market (confidence score)
- If confidence > 85%, executes trade
- Logs full reasoning for audit
Key Settings

| MAX_TRADE_SIZE | $100 | Per-trade limit |
| COOLDOWN | 60s | Between same-market trades |
| POLL_INTERVAL | 60s | News check frequency |
