42AI launches with $62.5M to model how traders behave in volatile markets

42AI launched with $62.5 million in seed funding from the founders and Infinity Group to build a behavioral world model that predicts how individual traders will act. Ten large brokerages are working with the company, which says revenue has reached seven figures and claims 98% accuracy on whether trading flows land inside a predicted range. The model adapts an 8B-parameter Llama 3.1 and is trained on customer data spanning about 30 million people.
