#prediction-market

Use when a user wants to know the probability of events such as political elections, stocks, cryptocurrencies, or sports, mentions Polymarket, prediction markets, or odds, or wants to track and evaluate a batch of predictions. Use the official CLI for read-only queries; it is free and needs no wallet. Form your own judgment first, then compare it with market prices, record it in predictions.csv, and calculate the Brier score after settlement. Do not place orders, do not touch private keys, and do not give buy or sell advice. Use case: Let the agent use Polymarket's free interface to check odds and trends, give its own probability and record it, then score it after settlement.

Intermediate tutorial: install Polymarket's official command-line tool. The API is free and needs no wallet. Have Claude Code or another agent check markets, look at odds trends, search the web for information, give its own probability and compare it with the market, log predictions in a table, and score them with the Brier score after they settle. If you want to trade, use your own account and place orders yourself.
