The Justice Department is asking hard questions about Nvidia’s $12.93 billion deal to buy Hugging Face, and the chipmaker’s rivals should pay attention. Reuters reported on Wednesday that federal antitrust officials have inquired into how the acquisition would affect competition in artificial intelligence, citing two people familiar with the matter. CNBC later confirmed the inquiry with its own source.
At the center of the probe is a simple worry: Hugging Face is where much of the AI world goes to get its models. Its platform hosts open-source models, datasets, and developer tools, and investigators want to know whether owning it would let Nvidia capture what Reuters’ sources described as a fundamental distribution point for AI.
Nvidia announced the deal on Sept. 3 and expects it to close in the first half of 2027. The company has said Hugging Face would keep working with a range of chip, cloud, and AI providers, and would stay open to the wider AI ecosystem.
That promise is now under a microscope.
What the DOJ is asking about the Nvidia Hugging Face deal
According to Reuters, the department’s recent questioning covers Nvidia’s acquisitions, investments, and sales practices, plus whether the chip designer has pressured its customers. On Hugging Face specifically, officials asked whether the deal would let Nvidia capture a key distribution hub for AI, use the platform as a bargaining chip in negotiations, or disadvantage rival chipmakers and alternative model repositories. They also asked about Hugging Face’s competitors.
A Justice Department spokesperson declined to comment on any pending matter, citing longstanding policy, but added: “This DOJ under President Trump’s leadership will continue to prioritize advancement of Super Intelligence for the betterment of the American people.” Nvidia declined to comment, and Hugging Face representatives did not respond to Reuters’ request for comment.
None of this is a finding against the deal. It is an inquiry, and inquiries end in different places. Some become lawsuits. Many do not. But the questions themselves tell you what worries enforcers: not just who makes the fastest chip, but who controls the place where AI models change hands.
Why Hugging Face matters to Nvidia’s rivals
Hugging Face is not a household name, but inside the AI industry it is close to infrastructure. Researchers post models there. Startups test on them. Big companies pull them into products. If one chipmaker owns the front door, rivals have a fair reason to ask what changes, even if nothing changes on day one.
Nvidia’s pitch has always been that Hugging Face stays open. Chief executive Jensen Huang said at the announcement that the platform would remain open to third-party processors, frameworks, and cloud services. Enforcers are now testing that assurance against a different question: does ownership itself shift incentives, regardless of what the owner promises today?
Consider the scale involved. Nvidia has become a cornerstone of the tech economy and the AI boom, backing major players such as Anthropic and OpenAI while pushing data center buildouts around the world so its chips can power AI’s heavy computing needs. A company that big buying the main open-source model hub is exactly the kind of deal antitrust officials are built to examine.
The wider Nvidia investigation
The Hugging Face questions did not arrive out of nowhere. They sit inside a years-long Justice Department investigation into Nvidia’s conduct that began under former President Joe Biden and has continued under President Donald Trump, Reuters reported. There is no indication Trump intervened in the matter.
Bloomberg has previously reported that the department was looking into whether Nvidia structured a licensing agreement with AI chip startup Groq in a way that would avoid antitrust review. Reuters added that officials have also examined whether Nvidia steered more AI chips to customers that bought networking equipment alongside Groq processors, and that Nvidia’s acquisitions of SchedMD and Run:ai, completed in December 2025, are also under review. Bloomberg also reported that Nvidia has considered a deal with Reflection AI.
Put together, the pattern is clear enough. Enforcers are not looking at one transaction in isolation. They are mapping how Nvidia buys, invests, licenses, and sells across the AI stack, and asking whether the pieces add up to an advantage competitors cannot match.
Why this matters
For Nvidia, the stakes are strategic, not just legal. Any action by the Justice Department could ripple through the chip industry and challenge an investing and acquisition strategy that has extended Nvidia’s influence well beyond its own hardware. Hugging Face was meant to deepen that reach into software and developer tools. Scrutiny could slow it, reshape its terms, or, in the extreme case, block it.
For everyone else in AI, the case is a preview of a bigger fight. As models become infrastructure, the platforms that distribute them start to look like the app stores and search engines of an earlier era: neutral on the surface, decisive underneath. Regulators spent a decade learning that lesson with phones and the web. They look less willing to wait that long with AI.
Don’t expect a quick resolution. The deal is not slated to close until the first half of 2027, which gives both sides months to argue. Nvidia will point to its open-platform pledge and to a market full of competing model hubs. The Justice Department will keep asking whether a promise from the biggest chipmaker in AI is a substitute for competition itself. That question, more than any single document in the inquiry, is what this fight is really about.
FAQ
Is the DOJ investigating Nvidia’s Hugging Face deal?
Yes. Reuters reported on Oct. 28 that Justice Department officials have asked how Nvidia’s $12.93 billion deal to buy Hugging Face would affect AI competition, and CNBC independently confirmed the inquiry with its own source.
What is the DOJ worried about in the Nvidia Hugging Face deal?
Investigators want to know whether owning Hugging Face would let Nvidia capture a fundamental distribution point for AI, disadvantage rival chipmakers, or use the platform as a bargaining chip in commercial talks. They have also asked about Hugging Face’s competitors.
When will Nvidia’s Hugging Face deal close?
Nvidia has said the acquisition is expected to close in the first half of 2027. The deal was announced on Sept. 3, 2026, at a value of $12.93 billion, and Nvidia says Hugging Face will keep supporting a range of chip, cloud, and AI providers.
Does a DOJ inquiry mean Nvidia did something wrong?
No. A government investigation is not evidence of wrongdoing and does not necessarily lead to a lawsuit, Reuters noted. The inquiry is part of a broader years-long Justice Department examination of Nvidia’s acquisitions, investments, and sales practices.
