The US Justice Department is scrutinizing Nvidia’s $12.9 billion acquisition of Hugging Face, asking detailed questions about how the deal would affect competition in artificial intelligence, including whether it would give Nvidia control over a critical distribution point for AI models. The inquiry adds a new layer of regulatory pressure on Nvidia, already the world’s most valuable company and a dominant supplier of AI chips.

According to people familiar with the matter, antitrust officials want to know whether the purchase would allow Nvidia to "capture a fundamental distribution point for AI." They are also examining whether Nvidia could use Hugging Face to disadvantage rivals, for example by favoring its own models or restricting access to competitors’ models. The questions are part of a broader, years-long investigation into Nvidia’s business practices that began under the Biden administration.

What is Hugging Face?

Hugging Face is a widely used platform where developers share open-source AI models, datasets, and tools. It has become a central hub for the machine learning community, hosting hundreds of thousands of models, including popular open-source alternatives to proprietary systems. For many startups and researchers, Hugging Face is the default place to discover, download, and deploy AI models. Its importance has grown as open-source AI has gained traction, challenging the dominance of closed models from companies like OpenAI and Google.

Nvidia agreed to buy Hugging Face in September, promising to keep the platform open. The company expects the deal to close in the first half of 2027. If completed, the acquisition would mark a major expansion of Nvidia’s reach from hardware into software and model distribution. Nvidia has increasingly moved into software and models, leveraging its grip on AI chips to become a more integrated player in the AI stack.

Broader antitrust investigation

The questions about Hugging Face run alongside a sweeping Justice Department probe into Nvidia’s conduct. That investigation covers the chipmaker’s deals, its stakes in other firms, and how it sells chips, including whether it put pressure on buyers. The probe began under President Joe Biden and has continued into the current administration. Nvidia also faces an antitrust investigation in France, reflecting growing global concerns about its market power.

In a separate but related matter, last month the Justice Department was reported to be examining whether Nvidia structured its $20 billion deal with Groq to avoid a merger review. Instead of buying Groq outright, Nvidia licensed its technology and hired its top executives. Such arrangements can fall outside the scope of traditional merger notification requirements, but regulators are increasingly scrutinizing these "acqui-hire" or licensing deals for their competitive effects.

Nvidia’s expanding ecosystem

Nvidia’s dominance in AI chips—particularly its graphics processing units (GPUs) and the CUDA software ecosystem—has given it significant influence over the AI industry. The company’s hardware is essential for training and running large AI models, and its software platform is widely used by developers. By acquiring Hugging Face, Nvidia would gain control over a key distribution channel for AI models, potentially allowing it to shape which models are easily accessible and how they are optimized for Nvidia hardware.

Critics worry that Nvidia could use Hugging Face to entrench its position further. For example, it could prioritize models that run best on Nvidia hardware, making it harder for competitors’ chips to gain traction. Or it could restrict access to certain models for rivals. Nvidia has said it intends to keep Hugging Face open, but antitrust enforcers are likely to examine whether such promises are credible and enforceable.

Nvidia is also in talks with Reflection AI, a maker of open AI models that Nvidia already backs, about a takeover or a bigger investment. This suggests Nvidia is actively building out a portfolio of AI software and model assets, moving beyond its core chip business. Such vertical integration could bring efficiencies, but it also raises concerns about foreclosure and reduced competition.

Historical context and regulatory climate

The Justice Department’s scrutiny of Nvidia comes amid a broader push by regulators in the US and abroad to examine the concentration of power in the AI industry. The Biden administration took a tough stance on Big Tech, and the current administration has signaled that it will continue to prioritize antitrust enforcement in technology markets. The DOJ’s statement that it "will continue to prioritize advancement of Super Intelligence" reflects the White House’s focus on AI as a strategic technology.

Antitrust cases in tech have historically focused on consumer welfare, but regulators are increasingly considering effects on innovation, startups, and competitive dynamics. In the AI space, the concern is that a few large companies could control critical inputs—chips, data, models, and distribution platforms—making it difficult for new entrants to compete. The Hugging Face deal is a test case for how regulators will treat vertical integration in AI.

Similar concerns have arisen in other sectors. For instance, the DOJ’s investigation into Nvidia’s chip sales practices echoes past cases involving monopolization in semiconductors and other high-tech industries. The French antitrust probe adds a European dimension, and other jurisdictions may follow suit.

Potential theories of harm

Antitrust officials are likely to explore several theories of harm. First, the deal could lead to vertical foreclosure: Nvidia could use its control of Hugging Face to disadvantage rival chipmakers by making it harder for their hardware to be supported or optimized on the platform. Second, Nvidia could favor its own models or those of its partners, reducing the visibility of competing models. Third, the acquisition could raise barriers to entry by making it more expensive or difficult for new AI platforms to gain scale.

Another concern is data. Hugging Face hosts a vast amount of data about model usage, downloads, and performance. Nvidia could use this data to gain insights into competitive trends or to identify promising startups for acquisition or investment. The deal could also give Nvidia more leverage in negotiations with cloud providers and enterprises.

Nvidia’s defense will likely emphasize that Hugging Face is a community platform that will remain open and that the acquisition will accelerate innovation by combining Nvidia’s hardware expertise with Hugging Face’s software ecosystem. The company may argue that the deal is pro-competitive because it will make it easier for developers to deploy AI models on Nvidia hardware, reducing friction and improving performance.

What’s next?

The Justice Department’s inquiry is at an early stage, and it is not clear whether it will result in a formal challenge to the deal. The review could take months, and Nvidia has said it expects the transaction to close in the first half of 2027. In the meantime, the DOJ may request additional documents and conduct interviews with competitors, customers, and industry experts.

The outcome will be closely watched by the AI industry. If the deal is cleared with conditions, it could set a precedent for how other vertical acquisitions in AI are treated. If it is challenged, it could signal a more aggressive approach to antitrust enforcement in the AI sector. Either way, the investigation underscores the growing regulatory scrutiny of Nvidia’s expanding empire.

Nvidia’s market position is unprecedented for a semiconductor company. Its GPUs are the workhorses of AI, and its CUDA software has become a de facto standard. The company’s revenue has soared, and its market capitalization has topped $3 trillion at times. Such dominance attracts attention from regulators worldwide, and the Hugging Face deal is just one of several probes Nvidia faces.

The French antitrust investigation, for example, is examining Nvidia’s practices in the graphics card market and its role in AI. The DOJ’s Groq inquiry shows that regulators are looking closely at deals that might skirt merger review. And the broader probe into Nvidia’s conduct could result in remedies that affect how the company sells chips and interacts with customers.

For Hugging Face users, the key question is whether the platform will remain open and neutral. Nvidia has promised to maintain openness, but the antitrust review will test whether such commitments are sufficient. Developers and startups reliant on Hugging Face may worry about changes to the platform’s policies or priorities after the acquisition.

The AI industry is at a critical juncture, with open-source models gaining ground and proprietary models pushing the frontier. The balance between openness and control is a central tension, and the Hugging Face acquisition sits right at that intersection. How regulators handle the deal will shape the future of AI competition.

As the investigation unfolds, Nvidia will likely face intense scrutiny of its business practices. The company has hired lobbyists and legal experts to navigate the regulatory landscape. It has also argued that its success is due to innovation and that it competes fairly. But with great market power comes great scrutiny, and the DOJ appears determined to examine whether Nvidia’s actions have harmed competition.

The timing of the review is also significant. The AI boom has created enormous wealth and power for a handful of companies, and governments are eager to ensure that markets remain contestable. The DOJ’s questions about Hugging Face suggest that regulators are thinking beyond traditional consumer welfare and considering the broader structure of the AI industry.

Nvidia’s stock price has been volatile amid regulatory news, but the company remains highly profitable. Its data center business is booming, and demand for its chips shows no signs of abating. The Hugging Face deal is a small fraction of Nvidia’s market value, but its strategic importance could be outsized.

The investigation is ongoing, and no final decision has been made. The DOJ could clear the deal, impose conditions, or sue to block it. Nvidia could also abandon the deal if the regulatory hurdles prove too high. For now, the company is proceeding with its plans, and the AI world is watching.
