The Nvidia Hugging Face DOJ probe has put one of the largest artificial intelligence deals on record under a new regulatory spotlight. The United States Department of Justice is asking whether Nvidia's $12.93 billion purchase of open-source AI platform Hugging Face would give the chip giant control over a fundamental distribution point for artificial intelligence, Reuters reported on Wednesday, October 28, 2026, citing two people familiar with the matter. The questions arrive as antitrust enforcers continue a years-long examination of Nvidia's conduct, and they raise fresh uncertainty over a transaction the company expects to close in the first half of 2027.
Nvidia, the world's most valuable company and the dominant supplier of the chips that power systems such as ChatGPT and Anthropic's Claude, announced in early September 2026 that it had agreed to buy Hugging Face. The deal, worth $12.93 billion in total, would hand Nvidia ownership of the platform where millions of developers share, test and download AI models. Regulators are now asking whether that combination could disadvantage rivals, tilt the market toward Nvidia hardware, or give one company too much say over how AI tools reach developers.
According to Reuters, Justice Department officials have recently questioned how the Hugging Face acquisition would affect competition in artificial intelligence. The central question, put to people familiar with the matter, is whether the deal would let Nvidia capture a fundamental distribution point for AI — the place where developers find and share the models that run on its chips and on rivals' hardware alike. Officials are also asking how Nvidia might use the newly acquired business to gain leverage, and they have sought information about Hugging Face's competitors.
The inquiry is not a finding of wrongdoing. Government investigations are not evidence that a company has broken the law, and they do not necessarily result in lawsuits, Reuters noted. Nvidia declined to comment on the report, and Hugging Face representatives did not respond to a request for comment. A Justice Department spokesperson declined to comment on any matters before the department, 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."
CNBC later confirmed the probe with an unnamed source, according to PYMNTS, while Bloomberg has separately reported that the department has been examining whether Nvidia structured a licensing agreement with AI chip startup Groq in a way that would avoid antitrust review. The department's questions about the Hugging Face deal and details of its wider pursuit of Nvidia's conduct are reported for the first time in the Reuters account, which was published on October 28.
Hugging Face has become a central hub for open AI development. At the time of the deal, Nvidia said in a press statement that more than 18 million people and more than 200,000 companies used the platform to share at least 3 million models and 500,000 datasets. The company also sells infrastructure and collaboration tools to organisations working with closed, proprietary AI, including chip companies. That breadth is exactly why the platform matters to regulators: it is used by teams working across different chips, cloud providers and software frameworks, not only by Nvidia customers.
Nvidia chief executive Jensen Huang announced on September 3, 2026 that the company had agreed to acquire Hugging Face. At the time, Huang said the deal would help "expand access to AI for developers and institutions worldwide." Nvidia also pledged that Hugging Face would remain open to models, frameworks, clouds and computing platforms from across the industry, and that Nvidia's own chips would not be required to use it. Those promises are now likely to be tested against the Justice Department's questions about distribution and leverage.
The Hugging Face purchase is Nvidia's second-biggest deal, behind only its roughly $20 billion Groq transaction at the end of last year, according to coverage of the deal. The closest comparison drawn in reporting is GitHub, the software repository Microsoft acquired in 2018 for $7.5 billion. Both cases involve a dominant technology company buying the platform where developers gather — and both attracted close regulatory attention to what the buyer might do with that position.
Nvidia's market position explains why enforcers are paying attention. The company has the biggest share of the market for AI chips, which power the likes of ChatGPT, Anthropic's Claude and similar tools. Competitors including Broadcom and Alphabet's Google design processors together, seeking to beat Nvidia hardware with chips purpose-built for specific tasks and AI software. Advanced Micro Devices has said it can produce technically superior hardware and has struck billion-dollar deals with several AI labs and cloud computing operators. Yet Nvidia has remained, in Reuters' words, "a singular force in AI," backing major players such as Anthropic and OpenAI while spurring data centre development around the world so its chips can power AI's voracious computing needs.
The Hugging Face questions do not stand alone. The broad Nvidia examination started under former Democratic President Joe Biden and has continued under the administration of Republican President Donald Trump, during which time Nvidia has been the most valuable company in the world. There is no indication that Trump has any involvement in the probe, Reuters reported, and the probe may not result in any Justice Department action.
As part of the wider examination, the department has looked at Nvidia's acquisition of SchedMD, completed in December 2025, which sparked worries among AI specialists about their access to SchedMD's open-source software, which helps run supercomputers relevant to national security. Nvidia has vowed to continue open access and support for that software. The department has also looked at Nvidia's acquisition of Run:ai, which makes software that helps AI chips run more efficiently.
The Groq matter has drawn particular scrutiny. The department has scrutinised Nvidia's conduct following its 2025 deal to license technology from Groq and hire its engineers, exploring whether Nvidia unfairly offered larger allocations of AI chips if customers purchased its networking equipment and Groq processors. That line of questioning raises the question of whether Nvidia used its dominant product to push into a newer market. Groq did not respond to a request for comment.
Staff-led investigations at the Justice Department often take years and can stretch from one administration to the next, Reuters noted. The department also routinely seeks input from companies when evaluating proposed mergers. In a pointed remark, the department spokesperson said: "It would be inappropriate for the Department to conduct a merger investigation under the guise of a conduct investigation." That comment signals a live debate over how the Hugging Face questions fit within the older conduct probe — and how Nvidia may frame its response.
Neither Nvidia nor Hugging Face offered a substantive public response to the October 28 report. Nvidia declined to comment, and Hugging Face representatives did not respond to Reuters' request for comment. The Justice Department spokesperson's statement — that the department "will continue to prioritize advancement of Super Intelligence for the betterment of the American people" — was the only official comment from the government side.
The market reaction was measured. Shares of Nvidia slipped about 1% on Wednesday following the reports, according to Stocktwits, which also noted that retail sentiment around the stock stayed within bullish territory over the past 24 hours, with message volume at normal levels. Nvidia stock has gained about 15% year to date, a reminder that investors have so far treated regulatory scrutiny as a risk to monitor rather than a reason to abandon the AI trade.
The relationship between Nvidia's chief executive and the White House adds a political dimension that both sides will watch. Huang has developed a relationship with Trump, who has touted American AI, and the chief executive joined the president's diplomatic trip to China. Trump, who has disclosed owning Nvidia stock, separately awarded Huang the National Medal of Science for advancing AI hardware. Reuters stressed that there is no indication Trump has any involvement in the probe. Trump critics have previously accused the administration of political intervention at the Justice Department, which the administration has disputed.
The Nvidia Hugging Face DOJ probe matters because it tests where the AI boom's infrastructure ends and its marketplace begins. Chips are the foundation of modern AI, but platforms such as Hugging Face decide which models developers discover, download and deploy. If one company controlled both the dominant hardware and the leading distribution point, rivals fear it could steer developers toward its own chips, favour its own software, or quietly disadvantage competing hardware — even without an explicit ban on rivals. That is the theory regulators are now probing, and it is why the "distribution point" question sits at the centre of the story.
The case also matters for the wider AI deal-making wave. Nvidia has extended its influence through a string of acquisitions and investments, backing major players such as Anthropic and OpenAI and buying software and chip assets that strengthen its ecosystem. Any action by the Justice Department could ripple through the chip industry and challenge that investing and acquisition strategy, Reuters reported. Other AI deals — including the reported consideration of a deal with Reflection AI, noted by Bloomberg — would be read in the same light. For startups, the probe signals that large AI acquisitions will face close review, even when the buyer promises to keep a platform open.
For developers, the practical stakes are concrete. Hugging Face hosts models optimised for many kinds of hardware, and its open character is part of its appeal. If Nvidia keeps the platform genuinely open, as it has pledged, developers may notice little change. If regulators find reasons to doubt that promise, remedies could follow — from conditions on how the platform is run to, in the most severe outcome, a challenge to the deal itself. Nvidia pre-disclosed in deal filings that regulators could require changes to platform practices, according to coverage of the filings, suggesting the company priced in at least some structural remedies when it signed.
Several paths are open. The Justice Department could continue asking questions and close the matter without action, as often happens with inquiries. It could seek formal remedies or conditions as the price of allowing the deal to close in the first half of 2027. Or, if officials conclude the acquisition would substantially lessen competition, it could move to challenge the transaction. No formal challenge or second request from regulators had been publicly detailed as of October 28, according to Crypto Briefing's summary of the reporting, and the inquiry remains at an early stage by that account.
Investors will watch Nvidia's next earnings report and any further comment from the company, as well as the progress of the broader conduct probe. Developers will watch for any change in Hugging Face's policies on model availability, hardware support and data access. And rival chipmakers — AMD, Broadcom and Google among them — will watch for any opening the scrutiny creates, whether in the form of remedies, delays or a shift in developer sentiment. The closing timeline, the first half of 2027, leaves months for all of those threads to develop.

The Justice Department has asked how the deal would affect competition in AI, including whether it would let Nvidia capture a fundamental distribution point for AI, Reuters reported on October 28, 2026. The questions come alongside a years-long investigation into Nvidia's conduct. An investigation is not evidence of wrongdoing and may not lead to any action.
The deal is valued at $12.93 billion in total: about $11.9 billion payable to Hugging Face stockholders, plus up to $1 billion set aside for an employee equity retention programme for staff who join Nvidia.
Nvidia expects the transaction to close in the first half of 2027, subject to closing conditions that include required regulatory approvals.
Investigators have examined Nvidia's December 2025 acquisition of SchedMD and its purchase of Run:ai, and have scrutinised Nvidia's conduct after a 2025 deal to license technology from chip startup Groq and hire its engineers, according to Reuters.
Nvidia declined to comment on the October 28 report, and Hugging Face representatives did not respond to a request for comment. Nvidia has previously said Hugging Face would continue to support work with a range of chip, cloud and AI providers.
