Numerai is a hedge fund that uses a unique crowdsourced AI model approach, providing thousands of data scientists worldwide with obfuscated financial data and rewarding them with cryptocurrency (NMR) for submitting accurate market prediction models. The platform aggregates these diverse, independently developed models using a meta-model approach, combining predictions from the global data science community into a single, ensemble investment strategy that trades global equities. Numerai's proprietary data obfuscation technique scrambles the underlying securities information while preserving the mathematical relationships that make predictions valuable, allowing data scientists to build models without knowing what they are predicting—eliminating trading on the predictions themselves. The Numerai Signals product extends this model by allowing data scientists to submit predictions built on any data source, broadening the diversity of signals available to the meta-model.
