European Union competition chief Margrethe Vestager warned of a \u201chuge bottleneck\u201d in\u00a0Nvidia Corp.<\/a>\u00a0AI chips supply, but said watchdogs are still making up their minds about what, if anything, to do about it.\u00a0<\/p>\n \u201cWe\u2019ve been asking them questions, but that is really preliminary,\u201d she told Bloomberg during a trip to Singapore. That \u201cwould not\u201d so far \u201ctick the box of being regulatory action.\u201d<\/p>\n Nvidia<\/a> has drawn the attention of regulators since becoming the biggest beneficiary of the artificial intelligence spending boom. Its graphics processing units \u2014 or GPUs \u2014 \u00a0are prized by data center operators for their ability to crunch the massive amount of information required to develop AI models.\u00a0<\/p>\n The chips have become one of the hottest commodities in the tech world, with cloud computing providers competing with one another to get access to them. Nvidia\u2019s in demand H100 processing units have helped them gain a market share of above 80%, according to estimates, ahead of rivals\u00a0Intel Corp.<\/a>\u00a0and\u00a0Advanced Micro Devices Inc.<\/a>\u00a0<\/p>\n Despite the supply squeeze, Vestager said that secondary markets in the supply of AI chips could help to spark innovation and fair competition.<\/p>\n But she said companies that are dominant could face certain restrictions on their behavior in the future.\u00a0<\/p>\n \u201cIf you have that kind of dominant position in the marketplace, there are things that you cannot do that a small company can do,\u201d she said. \u201cBut other than that, as long as you do your business and are respecting that, you\u2019re good.\u201d<\/p>\n<\/div>\n\nSubscribe to the CEO Daily newsletter to get global CEO perspectives on the biggest stories in business.
