ARM Holdings was founded in 1990 as a joint venture between Acorn Computers, Apple, and VLSI Technology, spun out of Acorn's Cambridge offices to commercialise a reduced instruction set computing architecture originally developed for the BBC Micro. The founding premise was licensing intellectual property rather than manufacturing chips, a model that was genuinely unusual at the time and has since become the template for a significant portion of the global semiconductor industry.
The company floated on the London Stock Exchange and Nasdaq in 1998, and was taken private by SoftBank in 2016 in a deal valued at approximately £24 billion. A proposed acquisition by Nvidia collapsed in 2022 following regulatory opposition on both sides of the Atlantic. ARM subsequently relisted on Nasdaq in September 2023, one of the more closely watched technology IPOs of that year.
Today ARM licenses processor architectures and physical IP to semiconductor designers across mobile, automotive, data centre, and embedded markets. Its architecture underpins the overwhelming majority of smartphones shipped globally, and the company has been expanding its presence in server and AI inference workloads as cloud providers design custom silicon.
For operators and scale-up leaders, ARM is a useful lens on several structural questions: how IP-led business models scale without capital-intensive manufacturing; how a British deep-tech asset navigates geopolitical pressure between US and Chinese technology ecosystems; and how the semiconductor supply chain is being reshaped by the shift toward custom silicon at hyperscale customers. The company's licensing economics, where a single architecture generates royalties across billions of devices, remain one of the more studied examples of platform leverage in hardware.
