About Metaforecast
What is Metaforecast?
Metaforecast is a search engine for prediction markets and forecasting platforms. It aggregates data from sources like Polymarket, Metaculus, and Manifold Markets. Users enter search terms to find specific forecasts and see their current percentage probabilities. The tool also provides a quality rating for different sources to help users evaluate data reliability.
The platform has a Twitter bot that responds to tags with the closest available predictions. It shows the liquidity, number of forecasters, and the last update time for each question. While the site is not under active maintenance, the search index contains historical and active forecasts from across the industry.
