Numerai is a San Francisco hedge fund that crowdsources its stock-market trading models from a global community of data scientists. Participants download obfuscated, regularized financial datasets, train machine-learning models, and submit predictions each weekly round through a single GraphQL API at api-tournament.numer.ai. Models are staked with the Ethereum-based NMR token and earn performance-based payouts for accurate, original signals. The platform spans Numerai Classic, Numerai Signals (bring-your-own stock signals), and Crypto Signals, with official Python tooling (numerapi, numerai-cli, numerai-tools) and cloud Compute Prediction Nodes for fully automated round submissions.
