Jeff Bezos backs CuspAI to discover new materials with generative AI

My take: CuspAI, a two-year-old Cambridge startup, is set to close a $400M round with Bezos Expeditions and Kleiner Perkins at a $2.6 billion valuation. The company applies generative AI to materials discovery and already counts ASML, Meta, and Hyundai as customers; its systems helped develop materials that can remove PFAS contaminants from drinking water. The investment lands six days after Bezos announced Prometheus, his $41B physical AI lab.
