DOJ scrutinizing Nvidia's $12.93B Hugging Face acquisition over AI competition concerns (Oct 28)

What happened

Reuters reported Wednesday evening, citing two people familiar with the matter, that the U.S. Justice Department has made inquiries into whether Nvidia's $12.93 billion deal to buy open-source platform Hugging Face would harm competition in artificial intelligence. DOJ officials are asking whether the acquisition would let the chip giant 'capture a fundamental distribution point for AI' — leverage to disadvantage rivals or extract negotiating concessions — and have asked about Hugging Face's competitors. The questioning sits inside a broader, years-long DOJ investigation into Nvidia's conduct covering acquisitions, investments, sales practices, and customer pressure; the Hugging Face angle and details of the continued pursuit are reported here for the first time. Investigators are also reviewing Nvidia's December 2025 SchedMD and Run:ai acquisitions and the 2025 Groq licensing-and-talent arrangement, including whether chip allocations were steered to customers that bought networking gear tied to Groq. Nvidia declined to comment; a DOJ spokesperson declined to discuss pending matters, adding the department under President Trump will prioritize 'advancement of Super Intelligence.'

Who’s affected & sources

Who’s affected

  • Nvidia (NVDA): deal-block or deal-conditioning risk on a $12.93B flagship acquisition; regulatory overhang on its broader invest-and-acquire strategy. Semiconductor/AI dealmaking broadly: Hugging Face-related ecosystem names and AI M&A targets face a higher bar; rival chipmakers (AMD, Broadcom) are indirect beneficiaries of any constraint on Nvidia's distribution leverage.

Samsung posts record Q3 operating profit of 107.4 trillion won on AI chip boom, warns chip shortage will deepen next year

What happened

Samsung Electronics reported record third-quarter operating profit of 107.4 trillion won (about $80 billion), up nearly ninefold from 12.2 trillion won a year earlier, driven by booming demand for AI memory chips. Revenue climbed about 127% to roughly 195 trillion won, and Samsung said it is the first global technology company to post quarterly operating profit above 100 trillion won. The semiconductor division generated 106.5 trillion won in operating profit — about 99% of group profit — on a sharp ramp in sixth-generation high-bandwidth memory (HBM4) and server storage orders. Net profit of about 75 trillion won missed the roughly 84 trillion won consensus estimate. Samsung also declared a third-quarter dividend of 30 trillion won (4,601 won per share) and said memory demand will keep expanding in Q4 and the chip supply shortage will deepen next year.
