Numerai Raises $30M Series C Funding Round
5X Valuation Increase from 2023 Raise

One of our most interesting investments at FJ Labs, Numerai, a hedge fund build on top of the world’s largest data science tournament, raised a $30M Series C led by top university endowments and values the company at $500M, a 5X increase from its last valuation in 2023. Existing investors, including Union Square Ventures, Shine Capital, and Paul Tudor Jones, also participated. This exciting milestone comes on the heels of JPM securing $500M of capacity in Numerai’s fund.
Numerai’s growth continues to accelerate: over the past three years, it has grown AUM from ~$60M to $550M, including an extra $100M this past month alone. In 2024, Numerai’s global equity hedge fund delivered a net return of 25.45% with only a single down month and a 2.75 Sharpe. With the new equity capital and JP Morgan’s capacity, the company is now positioned to scale its AI hedge fund toward $1B in AUM and beyond.
