Steps
Once connected (see setup above), use the Polymarket tool:
- In Copilot Chat: "List active Polymarket markets related to [topic]"
- Copilot returns market list with slugs and current prices
- Ask: "Fetch current price for [specific market] and convert to probability"
Example Prompt
Try this with Copilot using the Polymarket tool
List active Polymarket markets for US economic events. Return structured JSON with market slug, title, current price (as probability percentage), and volume for each.
Tips
- Store market slugs from the list_markets call to make subsequent price fetches efficient
- Ask for both current price and volume to distinguish liquid high-confidence markets from thin illiquid ones
- Build a probability dashboard that refreshes prices automatically using market slugs as persistent identifiers
