PhysicsX is pushing AI investment toward a less flashy but expensive corner of technology: engineering simulation. The London company raised $300 million in Series C funding at a valuation of about $2.4 billion.
From slow simulation loops to fast model screening
Temasek led the round, with Nvidia, Siemens, Applied Materials, Atomico, M&G and Intrepid Growth also participating. That mix matters: Nvidia brings the compute ecosystem, Siemens brings industrial workflows, and Applied Materials knows semiconductor equipment.
The company trains neural networks to predict physical behavior so teams can test many designs quickly before spending time on high-precision simulation or physical prototypes. Aircraft engines, chips, batteries and rocket components are the kind of workloads in view.
PhysicsX calls the next step large physics models. If they work, engineering could move from a slow design-simulate-redesign cycle toward a workflow where models screen many options and engineers reserve the expensive checks for the best candidates.
