London-based PhysicsX has announced an oversubscribed $300 million Series C financing at a valuation of approximately $2.4 billion, fast-tracking the rollout of its physics AI platform for industrial engineering.
A Temasek-led syndicate
Singapore investment company Temasek led the round, with new investors M&G Investments and Intrepid Growth Partners joining existing backers Applied Materials, Atomico, General Catalyst, July Fund, NGP, NVIDIA, Radius and Siemens. Temasek first invested in PhysicsX in 2025 and has played a central role in supporting the company's international expansion.
Building Large Physics Models
PhysicsX is developing AI-native engineering software that predicts physical behavior in seconds rather than the hours or days required by traditional simulation workflows. Its platform is already deployed across aerospace and defense, semiconductors, industrial machinery, automotive, energy and materials. The new capital will fund global growth, platform expansion and frontier research into larger, pre-trained physics models the company calls Large Physics Models.
Growth that justifies the round
The financing follows a year in which PhysicsX doubled recognized revenue, tripled booked revenue and more than doubled its customer count, with the team growing past 300 people. Co-founder and CEO Jacomo Corbo said physics AI 'removes the binding constraint on hardware innovation,' enabling engineers to evaluate thousands of designs in the time it once took to assess a handful.
Where it fits in the funding wave
The deal lands inside a remarkable week for AI and robotics financing that has also seen NEURA Robotics close a record $1.4B Series C and Standard Bots raise $200M at a $1B valuation. With Siemens and NVIDIA already powering digital twin programs at TerraPower, PhysicsX's round signals how deeply industrial AI has become woven into the hyperscaler stack.
