It was probably inevitable, but companies are urging federal regulators to intervene or even block Nvidia\u2019s planned $40 billion purchase of Arm Holdings.\nGoogle, Microsoft, and Qualcomm are among a number of companies concerned about whether they will continue to have equal access to Arm technology after the acquisition closes, according to both Bloomberg and CNBC. And CNBC goes so far as to ask regulators around the world to scuttle the deal altogether.\nEarlier this month, UK-based AI chip start-up Graphcore asked the UK\u2019s Competition and Markets Authority to block the acquisition. Graphcore isn\u2019t even an Arm licensee, just an Nvidia competitor in the AI-processor space.\nBefore that, a group called Save Arm\u2014led by Hermann Hauser, founder of Acron Computers, which created Arm\u2014popped up almost immediately after the deal was announced last year, urging British Prime Minister Boris Johnson to stop the deal.\nThe US Federal Trade Commission has opened an investigation into the acquisition and has asked SoftBank, Nvidia, and Arm to provide more information and also is asked for input from other companies that might have relevant information.\nQualcomm, Microsoft, Google opposed\nThe three known U.S. opponents of the deal all have vested but differing interests in Arm. For Qualcomm, it\u2019s about IP as one of the largest Arm licensees in the world. For Microsoft and Google, it gets complicated.\n\u201cYou have to look for the shared interest that all the large clients of Arm might have,\u201d said Shane Rau, research vice president for IDC. Microsoft reportedly has custom Arm silicon for Azure, but it\u2019s more than that, he said.\n\u201cYou can consider Microsoft across whole-client, future Arm processors for Surface Pro and Azure processors for the data center. Google doesn\u2019t have data-center silicon but they do have an interest on the Android side, making sure the client-side ecosystem is allowed to proliferate so there are more clients in the hands of humans that generate data that go thru Google data centers,\u201d he said.\nWhat this all comes down to is mistrust vs reality. Nvidia argued it would not spend $40 billion on Arm only to kill the goose that laid the golden egg by playing favorites and thus harming its customer relations.\nNvidia CEO Jen-Hsun Huang recently told the Financial Times, \u201cI can unequivocally state that Nvidia will maintain Arm`s open-licensing model. We have no intention to \u2018throttle\u2019 or \u2018deny\u2019 Arm\u2019s supply to any customer.\u201d\nNvidia\u2019s opponents, however, don\u2019t seem to believe it and are assuming the worst from a company with no history of ever screwing a partner.\n\u201cIt risks closing down or limiting other companies\u2019 access to leading-edge CPU-processor designs which are so important across the technology world, from data centers, to mobile, to cars, and in embedded devices of every kind,\u201d said Graphcore CEO Nigel Toon on CNBC last December.\nJon Peddie, president of graphics market research firm Jon Peddie Research, isn\u2019t buying it. \u201cNvidia would be nuts to do such a thing, and I don\u2019t think Nvidia is nuts,\u201d he said. Qualcomm ships Arm-based chips in the billions, Nvidia ships Arm product in the thousands, he said. \u201cWhat possible benefit could Nvidia get from withholding tech from its largest customer?\u201d\nThat said, this isn\u2019t false concern about Nvidia\u2019s intentions, either. \u201cI know its genuine. I\u2019ve spoken with people at those companies. They are sincerely and genuinely concerned about this. They feel they are losing control of their destiny,\u201d he said.\nNvidia could allay such concerns by givig visibility into its R&D work so clients can keep up with developments and issue warnings if they see potential negative effects.\nHuang didn\u2019t get this far without some serious negotiating skills, which he used back in 2019 to get China\u2019s approval for Nvidia to buy Mellanox for $6.9 billion. \u201cHe understood their concerns, and what they were worried about, and was able to address them,\u201d said Peddie.
