The Tiny Cambridge Spinoff That Ended Up Inside Nearly Every Phone on Earth

Pick up almost any smartphone in the UAE right now — an iPhone, a Galaxy, a Pixel, a budget Android handset from a mall kiosk — and somewhere inside it is a processor built on designs from a company most people have never heard of: Arm. It doesn't make chips. It doesn't sell anything you can hold. What it sells is blueprints, and those blueprints are so deeply embedded in the modern world that Arm-based chips are now believed to ship in the tens of billions of units a year.

The company's story is a good reminder that the most important firm in an industry isn't always the one with its name on the box.

Born Inside a Barn, Spun Out of Acorn

Arm's roots go back to Acorn Computers, a Cambridge, UK company best known for the BBC Micro, a machine that shaped a generation of British computing in the 1980s. In the mid-1980s, Acorn's engineers — most notably Sophie Wilson and Steve Furber — needed a processor for their next machine and weren't satisfied with what Intel and Motorola were offering. So they designed their own: a RISC (Reduced Instruction Set Computer) chip that stripped processor design down to a small set of simple instructions, trading raw complexity for efficiency and low power draw.

That first chip, the Acorn RISC Machine, ran its first line of code in Acorn's Cambridge offices in April 1985. It was reportedly developed by a small team in well under two years — and it worked on the first try, drawing so little power that engineers initially suspected the test board was faulty.

The chip itself didn't make Acorn rich. What came next did.

1990: A Three-Way Spinoff With an Unlikely Partner

In November 1990, Acorn's processor design team was spun out into a new, independent company — a joint venture between Acorn, VLSI Technology, and, notably, Apple. Apple needed an efficient, low-power chip for an ambitious but ultimately ill-fated handheld device called the Newton, and the RISC design from Cambridge fit the bill. The new company was named Advanced RISC Machines Ltd — later shortened to the acronym everyone uses today.

This is the detail that makes Arm's history worth retelling: the company that now effectively defines mobile computing was built, in part, to serve a 1990s Apple product that flopped. The Newton was discontinued in 1998. Arm outlived it by decades and became vastly more consequential.

The Business Model Nobody Else Wanted to Try

Arm's real innovation wasn't just the chip — it was the business model. Rather than manufacturing processors itself, Arm chose to license its designs to other companies, who could then build their own chips around Arm's architecture, customized for their own products. Qualcomm, Samsung, Apple, MediaTek, and dozens of others have all built chips on Arm's instruction set over the years, paying licensing and royalty fees rather than buying finished silicon.

This "fabless IP licensing" model turned out to be perfectly suited to the explosion of mobile devices in the 2000s and 2010s. Phone makers needed chips that sipped battery power rather than guzzled it — the opposite of the priority that had shaped desktop PC processors for decades. Arm's architecture, efficient by design since its Acorn origins, was already built for that world. By the time smartphones went mainstream, Arm wasn't chasing the market; the market had grown to fit Arm's existing strengths.

The company went public on the London Stock Exchange and Nasdaq in 1998, trading as a standalone, UK-based intellectual property firm for the better part of two decades — an unusual position in an industry dominated by companies that both design and manufacture their own chips.

SoftBank, a Failed Nvidia Deal, and a Return to the Public Markets

Arm's ownership took a dramatic turn in 2016, when Japanese conglomerate SoftBank acquired the company for roughly $32 billion, taking it private. SoftBank held onto Arm for four years before attempting to sell it again — this time to Nvidia, in a $40 billion deal announced in September 2020 that would have handed the world's most valuable chip designer to the world's most valuable chip maker.

That deal collapsed under regulatory pressure. Antitrust regulators in the US, UK, and EU all raised concerns that Nvidia owning Arm would give it outsized control over an architecture its own competitors depended on — including, awkwardly, companies that compete directly with Nvidia's own chip business. The U.S. Federal Trade Commission sued to block the acquisition in December 2021, and by February 2022, SoftBank and Nvidia abandoned the deal, with Nvidia paying a termination fee reported at $1.25 billion.

SoftBank pivoted to a public listing instead. Arm debuted on the Nasdaq in September 2023 under the ticker ARM, pricing its IPO at $51 a share — the top of its targeted range — and raising roughly $4.87 billion, making it the largest US IPO of that year. Shares jumped nearly 25% on their first day of trading, pushing Arm's valuation to around $65 billion. SoftBank kept the overwhelming majority of the company, retaining roughly 90% of shares after the offering.

Why It Still Matters Beyond Phones

Arm's relevance today extends well past smartphones. Apple's switch to its own Arm-based "Apple Silicon" chips for Mac computers, starting with the M1 in 2020, proved that Arm's power-efficiency advantages could scale up to laptops and desktops — not just phones. Cloud providers including Amazon (with its Graviton chips) and Microsoft have built Arm-based server processors to cut data center power costs, an increasingly urgent concern as AI workloads strain electricity grids worldwide, including here in the Gulf, where several governments have made data center capacity and energy planning a stated strategic priority.

That's the quieter second act of Arm's story: a chip architecture born to save battery life on a 1980s British home computer project is now part of the conversation about how the world powers artificial intelligence. Few companies in tech history have had their founding-era design choices stay this relevant, for this long, across this many unrelated product categories.

The lesson for anyone sizing up the tech industry: the company whose logo you never see can still be the one holding the leverage.
