News-Triggered Arbitrage on Polymarket

This strategy (benjee-inc/polymarket-arb-dashboard) uses a news aggregation system that scans multiple RSS feeds, Twitter, and crypto-specific news sources for keywords related to active Polymarket events (e.g., election results, Fed decisions, crypto halving). When a significant news event is detected, the bot calculates the likely impact on related markets and submits limit orders to capture stale prices before other bots react. It also checks for arbitrage opportunities between related markets (e.g., 'BTC > $100k by Dec' and 'BTC > $90k by Dec') that may diverge immediately after news. The dashboard visualizes these opportunities in real time. Entry is aggressive (market orders if speed is critical) for the news-based leg, while the arbitrage leg uses limit orders. Implementation requires a fast backend (Node.js/Python with async requests) and careful management of Polygon transaction times. Quality depends heavily on news source latency and market liquidity.
