Jeff Bezos and UK government invest £2bn in AI startup CuspAI

A Cambridge‑based artificial‑intelligence firm, CuspAI, has secured a £2 billion investment from Amazon founder Jeff Bezos and the UK government’s sovereign AI fund. The funding, which brings the company’s valuation to $2.6 billion, is intended to support the development of an AI platform that will act as a “search engine for rare materials,” accelerating research and reducing the reliance on scarce metals in semiconductor supply chains.

CuspAI, founded two years ago, has raised $450 million (approximately £330 million) in its latest round. The company’s technology is designed to streamline the discovery of rare elements and alloys, cutting research timelines and helping chipmakers identify alternative materials. By providing a data‑driven marketplace for scarce resources, the platform aims to lower costs and improve sustainability across the electronics industry.

The investment underscores the UK’s commitment to advancing AI and securing critical supply chains for next‑generation technology. With the backing of high‑profile investors and a substantial valuation, CuspAI is positioned to become a key player in the global search for rare materials, potentially reshaping the future of semiconductor manufacturing.
