Metaculus
The serious forecaster's community.
Overview
Metaculus is a community of forecasters who submit calibrated probability estimates on long-horizon questions in science, geopolitics, AI, and global risk. There is no money involved — forecasters are scored on accuracy over time.
The platform is best known for its sophisticated questions, aggregated community predictions, and tournaments that often partner with research institutions. The Metaculus Prediction is widely cited as a benchmark for collective forecasting.
If you care about forecasting as a craft rather than as a way to make money, Metaculus is the deepest community on the internet.
