Announcing the Million Predictions Hackathon!
12
 Metaculus recently achieved a big milestone: **1,000,000 predictions** on over **7,000 questions**! We're celebrating by inviting you to participate in the *[The Million Predictions Hackathon](https://metaculus.medium.com/announcing-metaculuss-million-predictions-hackathon-91c2dfa3f39)* from December 3rd through 11th! This virtual hackathon is an opportunity to advance forecasting science and sharpen our community's aggregate forecasts with insights extracted from Metaculus's rich prediction dataset. Participants will receive support from the Metaculus engineering team as they explore questions like: #### Aggregation & Accuracy * Is the Metaculus Prediction is more or less accurate than average in certain categories? * How does prediction accuracy evolve over time? #### Evaluating Individual Forecasters * What are the forecasting patterns of the most skilled predictors? * How does forecasting skill transfer across domains? #### Open Inquiry * Are there new, valuable metrics that should be exposed to forecasters? * How should the Metaculus Track Record be improved? A **$10,000+ prize pool** will be awarded for the projects that contribute the most to the Metaculus ecosystem. Top projects will be featured on the site and may be incorporated into the platform! Visit the [full hackathon announcement](https://metaculus.medium.com/announcing-metaculuss-million-predictions-hackathon-91c2dfa3f39) for more on the structure, schedule, and prize payouts, and to [start your application](https://rutgers.ca1.qualtrics.com/jfe/form/SV_3eApmooPuRXXW4u).
