Singapore sovereign wealth fund Temasek has anchored the $300 million Series C financing in UK-headquartered artificial intelligence startup PhysicsX, according to an announcement.
The round, which values the British company at about $2.4 billion, was also backed by M&G Investments and Intrepid Growth Partners, alongside existing backers, including Applied Materials, General Catalyst, Siemens, and Atomico.
Temasek first invested in PhysicsX in 2025 and has supported the company’s international expansion and growth.
The fundraising comes as PhysicsX is developing and deploying its AI-native engineering platform to accelerate hardware innovation and drive engineering and manufacturing productivity in industrial organisations.
The company said its AI models can predict physical behaviour in seconds rather than hours or days, helping engineers test more designs and apply physics-based insights across the product lifecycle.
“We are giving engineers the ability to explore thousands of designs where they once managed a handful, in seconds rather than weeks, across the most demanding industries in the world,” said PhysicsX co-founder and CEO Jacomo Corbo.
Corbo said many of the physical economy’s toughest challenges, from better aircraft and semiconductors to energy systems, depend on how quickly engineers and machine operators can work through underlying physics problems.
PhysicsX’s platform is currently deployed across aerospace and defence, semiconductors, industrial machinery, automotive, energy, and materials industries.
The company said advances in model architectures and GPU economics have brought “physics AI at production scale” to an inflection point for industrial adoption.
The Series C financing comes amid rapid growth for the startup. PhysicsX said it has doubled year-over-year recognised revenue, tripled booked revenue and more than doubled its customer base over the past year.
Its workforce has expanded to more than 300 employees, doubling in size over the last 12 months, per the announcement.
PhysicsX said the fresh capital will support its global expansion, broaden its platform capabilities, and fund frontier research, including the development of larger pre-trained physics AI models, known as Large Physics Models.
Headquartered in the United Kingdom, PhysicsX has offices in London and New York and is expanding its presence in the San Francisco Bay Area and Singapore, where Temasek’s backing could help strengthen its footprint in Asia.
