ToolKnowing what Polymarket is currently trading is itself useful information. Active markets reflect what participants believe is worth pricing right now — a real-time signal of which events carry enough uncertainty and interest to attract trading attention. The market list is a window into collective attention and risk perception.
The list_markets skill returns active markets with their current prices, volume, and resolution dates. Browsing by topic or category reveals the range of events currently being priced, from electoral outcomes and Fed decisions to geopolitical events and scientific milestones.
Researchers scanning for relevant markets, journalists checking what prediction markets say about current events, and analysts looking for markets related to specific topics use this to discover what is actively being priced without visiting the Polymarket interface.

Claude lists active markets and provides analytical context about what they reveal collectively.
