Connects Claude to live prediction market data from Polymarket and Kalshi, pulling contract prices, volumes, and VWAP calculations for analysis. Built as part of a prediction markets research platform at Stanford GSB and Hoover Institution. The server exposes market queries and reportability checks, so you can ask Claude to analyze political, economic, or event markets without manually scraping dashboards. Useful when you're tracking forecast consensus, comparing implied probabilities across platforms, or building research workflows around crowd wisdom.
