Arithmancer is a prediction market application. Users can make trades on predictions, betting on how likely an event is to occur. Each prediction is an individual market with a market maker system modeled on Robin Hanson's logarithmic market scoring rules.
This was designed and tested as an internal corporate decision market. Using outside of an organization as a general application will likely require additional features (ex. ACLs, better form validation and security, etc.).
Note: This is not an official Google product.
pip install -r requirements.txt
Download and install the Google Cloud SDK, and use dev_appserver.py to run a local server for development. Create your first prediction by going to "/predictions/create".
This runs on App Engine and uses Google Cloud Datastore. Google Cloud SDK is a prerequisite for development and deployment.
python runner.py app_test.py
