Why it matters: Will Nvidia buy Arm? Such a move has the potential to shake up the tech world like nothing before, and a lot of people think it would be bad for the industry---including the UK company's co-founder, Hermann Hauser.

We heard last month that Nvidia was considering a bid for Arm, which was acquired by Softbank back in 2016 for around $31 billion. The Japanese conglomerate has been offloading some assets recently to help lessen the impact of the Coronavirus-related economic downturn and is looking to sell part or all of its stake in Arm.

Later reports claimed that Nvidia was moving closer to an acquisition, and was in talks with Softbank to buy Arm in a cash-and-stock deal that would value the firm at more than $32 billion. But Arm co-founder Hauser believes the sale would be a disaster.

Speaker to the BBC, Hauser said: "It's one of the fundamental assumptions of the ARM business model that it can sell to everybody. The one saving grace about Softbank was that it wasn't a chip company, and retained ARM's neutrality. If it becomes part of Nvidia, most of the licensees are competitors of Nvidia, and will of course then look for an alternative to ARM."

Largest tech deals in history:

Company Acquisition Price Year
Dell EMC $64 billion 2015
Avago Technologies Broadcom $37 billion 2015
IBM Red Hat $34 billion 2018
Softbank ARM Holdings $31.4 billion 2016
Microsoft LinkedIn $26.2 billion 2016

Hauser opposed Softbank's purchase of Arm in 2016, but admits it kept its promise to keep the focus of Arm's R&D at Cambridge---something he believes Nvidia will not do. "It will become one of the Nvidia divisions, and all the decisions will be made in America, no longer in Cambridge."

Arm licenses its technology to many of the world's tech giants, including Apple, Intel, Qualcomm, TSMC, Samsung, and others. The fact that several of these compete with Nvidia, which already produces Arm-based chips, means a purchase by team green would bring issues, especially if it increases licensing costs .

Hauser also believes the UK government should step in: "The great opportunity that the cash needs of Softbank presents is to bring Arm back home and take it public, with the support of the British government." He added that he would like to see it listed on both the London and New York Stock Exchanges.

Nvidia would face a number of regulatory hurdles before a deal went through, and recent reports suggest the company might just take a stake in Arm, rather than pursuing an outright purchase. We've also heard that Samsung is considering acquiring a small stake in the chip designer. The situation should become clearer in the next few weeks.
