What is Polymarket Prediction Markets?
This skill provides a programmatic interface to Polymarket, the world's largest decentralized prediction market. By leveraging this tool within the Openclaw Skills ecosystem, developers and researchers can access high-fidelity, real-time data on the probability of future events ranging from global elections to sporting outcomes. Unlike traditional polling, these markets represent financial skin-in-the-game, often providing more accurate forecasts than pundits or surveys.
The skill interfaces directly with the Polymarket Gamma API to retrieve market slugs, price data, and orderbook depth without requiring a private API key. It is designed for users who need actionable intelligence on market sentiment and event resolution probabilities across diverse categories like crypto, business, and technology.

- Monitoring cryptocurrency price targets and regulatory developments through market-driven forecasts.
- Automating data collection for research reports using the Openclaw Skills framework.
- Evaluating the likelihood of corporate acquisitions, IPOs, and product launches.
How Polymarket Prediction Markets Works

- The skill performs an asynchronous fetch request to the Polymarket public-search or events API endpoints.

- The script translates market prices into percentage-based probabilities (e.g., a 0.70 price corresponds to a 70% chance).
- Results are output to the console, allowing for quick analysis or further processing by other Openclaw Skills.
