PhysicsX raises $300M to push AI deeper into industrial engineering

London-based PhysicsX raised a $300 million Series C led by Temasek at an approximately $2.4 billion valuation, more than doubling its valuation in less than a year. The company develops AI-native engineering tools and Large Physics Models intended to accelerate or replace parts of conventional simulation workflows, allowing engineers to explore more designs across aerospace, defense, semiconductors, automotive, energy, materials, and data centers. New investors include M&G Investments and Intrepid Growth Partners, while Applied Materials, Atomico, General Catalyst, Nvidia, Siemens, and others returned. The round is a strong funding signal for industrial AI beyond chatbots: investors are backing models tied directly to expensive hardware design and manufacturing cycles. The key question is how broadly PhysicsX can prove accuracy and production value across different physical domains.
