London engineering-AI firm PhysicsX announced an oversubscribed $300M Series C at a ~$2.4B valuation (June 8), led by Temasek with NVIDIA, Siemens, Applied Materials, and Atomico participating. It is building 'Large Physics Models' that predict physical behavior in seconds instead of hours, letting engineering teams evaluate orders-of-magnitude more design variants. The company says revenue doubled year-over-year and headcount passed 300.
