PhysicsX

PhysicsX raised a $300m Series c at a $2.4bn valuation on 8 June 2026, led by Singapore's Temasek, making it one of Britain's most highly valued deep-tech firms. The company builds AI models that replace physics simulations for engineering-intensive industries, compressing tasks that previously took hours of compute into seconds. Its tools are 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, PhysicsX targets sectors where simulation costs are a genuine bottleneck. Rather than building a general-purpose AI, it trains models tightly coupled to physical laws, enabling predictions that remain accurate outside the training distribution. The company is London-headquartered and publicly committed to keeping its research base in the UK.

The Temasek-led round signals sustained international appetite for British deep-tech at scale. PhysicsX's $2.4bn valuation places it among the top tier of UK AI companies that have not yet sought a US listing, and the round's size suggests the next stage is either a late-stage growth round or a public market event. Its physical-AI niche is distinct from large language model companies and largely insulated from the commoditisation pressure hitting general AI.
