PhysicsX is a London-based AI company building what it calls Large Physics Models — the LLM analogy applied to the equations governing how engines, turbines and chips behave under stress. Founded by two former Formula 1 engineers, it closed an oversubscribed $300 million Series C in June 2026 at a roughly $2.4 billion valuation, led by Temasek with Siemens, Nvidia and Applied Materials returning. Its platform is deployed across aerospace, semiconductors, automotive and energy.
