PhysicsX
London AI company founded in 2019 that replaces engineering simulations for carmakers, aircraft makers and chip designers, compressing hours-long runs to seconds.
PhysicsX closed a $300m Series C on 8 June 2026, led by Singapore's Temasek, doubling its valuation to $2.4bn without any UK state fund taking part, making it one of Britain's most highly valued deep-tech firms.

Will PhysicsX's $2.4bn valuation hold once engineering simulation buyers face budget pressure?

UK Startups and InnovationBackground
PhysicsX builds AI models that replace physics simulations for engineering-intensive industries, compressing tasks that previously took hours of compute into seconds, with tools used in automotive aerodynamics, aircraft structural analysis, and semiconductor design. Founded in 2019 by Robin Tuluie and Jacomo Corbo, both with Formula One and aerospace engineering backgrounds, the company targets sectors where simulation cost is a genuine bottleneck.
Rather than building a general-purpose AI, PhysicsX trains models tightly coupled to physical laws, enabling predictions that remain accurate outside the training distribution. This physical-AI niche is distinct from large language model companies and largely insulated from the commoditisation pressure hitting general-purpose AI. The company is London-headquartered and publicly committed to keeping its research base in the UK.
PhysicsX doubled its valuation
PhysicsX closed a $300m Series c on 8 June 2026, led by Singapore's Temasek, doubling its valuation to $2.4bn without any UK state fund taking part . Temasek's existing exposure to Asian manufacturers ties directly into PhysicsX's Siemens and Applied Materials customer base, giving the round an industrial logic beyond financial return.
The raise landed inside a wider pattern the British Business Bank confirmed on 2 July: AI companies took a record 44% of UK smaller-business equity funding in 2025, with the top ten rounds alone absorbing 23% of the cash even as seed deals fell 27% . PhysicsX's valuation, reached without a US listing, sits at the concentrated end of that trend.
