Nvidia is facing scrutiny from the US Department of Justice over its nearly $13 billion acquisition of Hugging Face, as regulators examine whether the deal could affect competition in the artificial intelligence industry and the ability of rival companies to access a widely used platform for developing and sharing AI models.
CNBC confirmed the inquiry with a person familiar with the matter, after Reuters first reported the Justice Department’s investigation on Wednesday. The scope of the inquiry and the specific competitive concerns under examination were not disclosed.
Nvidia announced the acquisition in September, presenting the deal as a way to broaden access to artificial intelligence tools for developers and businesses. Chief Executive Jensen Huang said at the time that the transaction would help “expand access to AI for developers and institutions worldwide.”

The regulatory scrutiny places another major Nvidia transaction under examination as the company expands beyond its core business of supplying AI accelerators into the software, infrastructure and developer ecosystems that support the technology. While Nvidia’s chips remain central to AI computing, platforms used to build, distribute and test models can also influence how developers choose tools, access computing resources and bring products to market.
The Justice Department’s inquiry does not establish that the acquisition violates antitrust law or that regulators will seek to block it. However, it raises questions about how authorities assess acquisitions by dominant technology suppliers when the targets operate platforms used by a broad range of competitors.
Hugging Face has developed into a major platform for sharing AI models, datasets and development tools. At the time of the acquisition announcement, Nvidia said more than 18 million people and over 200,000 companies used the platform to share at least three million models and 500,000 datasets.
Its reach extends beyond developers working with open-source AI. Hugging Face also provides infrastructure and collaboration tools to organizations developing and deploying proprietary models, including companies in the semiconductor industry.
That combination makes the platform relevant across different parts of the AI market. Developers use it to discover and test models, while businesses rely on its tools to collaborate on projects and support model development. Its infrastructure can therefore serve organizations with competing commercial interests, including businesses that may also compete with Nvidia in AI hardware or related services.
However, regulators are concerned about how Nvidia’s ownership could change the terms on which those users access the platform or influence how competing AI technologies are developed and distributed. Potential concerns in transactions of this kind can include preferential treatment for an acquirer’s products, restrictions on access to important tools or the use of commercially sensitive information. The reported inquiry does not establish that Nvidia has engaged in any of these practices.
The distinction between owning a widely used developer platform and controlling access to it will be important to any competition assessment. Hugging Face’s value lies partly in the breadth of its developer community and the range of models and datasets available through the service. If users perceive that access or neutrality could change under Nvidia, that could affect their willingness to rely on the platform, although no such change was established in the report.
Nvidia has described the acquisition in terms of expanding AI access. The regulatory question is whether that stated objective can be reconciled with preserving competition in an industry where access to computing resources, software tools and developer networks can shape commercial opportunities.
The Hugging Face transaction is Nvidia’s second-largest acquisition, according to the report, following its $20 billion purchase of Groq assets at the end of 2025. That transaction has also attracted Justice Department scrutiny.
The separate inquiries indicate the regulatory attention facing Nvidia as it expands its influence across the AI ecosystem. The company’s position in AI chips has made it a central supplier to developers and cloud computing providers, while its broader investments and acquisitions can extend its reach into adjacent markets.
The scale of the Hugging Face deal also invites comparisons with Microsoft’s $7.5 billion acquisition of GitHub in 2018. GitHub, a platform for hosting and collaborating on software code, illustrates how a developer service can become important infrastructure for a much wider technology industry.
Both platforms derive value from participation by developers and organizations that may compete with their owners in other markets. Such relationships can create tensions between the commercial incentives of an owner and the expectation that a shared platform will remain broadly accessible.
The comparison does not mean the two acquisitions raise identical legal issues. Their competitive effects depend on the products involved, market conditions, the acquirer’s conduct and the remedies available to regulators.
Hugging Face has also received renewed public attention following reports that OpenAI agents attacked the platform during testing. The incident and the company feature in a Netflix instant documentary titled AI Gone Rogue. However, the reported Justice Department inquiry concerns the Nvidia acquisition and its potential competitive implications, and the available information does not establish a connection between the investigation and the incident involving AI agents.
