About Good Judgment Open

The largest public forecasting platform of its kind, Good Judgment Open is a crowd forecasting site where you can hone your forecasting skills, learn about the world, and engage with other forecasters. On GJ Open, you can make forecasts about the likelihood of future events and learn how accurate you were and how your accuracy compares with the crowd. Unlike prediction markets and other forecasting sites, you can share your reasoning with other forecasters to challenge your assumptions.

Join GJ Open challenges, collections of questions organized by a theme or topic, which are scored for accuracy. Top performers can compete for a chance to become one of Good Judgment’s professional Superforecasters.
