The US Justice Department has opened an inquiry into Nvidia's roughly $12.93 billion acquisition of open-source AI platform Hugging Face, seeking to understand how the deal could affect competition in AI, according to a Reuters report on October 28 citing two people familiar with the matter. The inquiry is at an early stage and it is unclear whether it will escalate into a formal challenge.
The deal was announced last month: Nvidia said it would acquire the world's largest AI open-source platform and jointly expand Hugging Face, strengthen its infrastructure and broaden global coverage. Hugging Face hosts a vast collection of model weights, datasets and demos — the de facto hub where AI developers download models and share work, and where most leading models publish first.
That hub position is exactly what regulators are examining. Observers have framed the concern as "control of a key distribution channel": if the chipmaker that dominates AI compute also owns the primary gateway through which developers obtain models, rival models — and the independence of the open-source ecosystem — could be affected. Sina Finance reported that antitrust enforcers are also pressing ahead with a broader probe into Nvidia's business conduct, with this inquiry part of that effort.
Key facts
· Deal size: $12.93B, announced in September, with plans to expand platform and infrastructure
· Examiner: US DOJ, focused on AI competition and control of key distribution channels
· Platform role: largest AI open-source hub, global distribution point for weights and datasets
· Context: DOJ's broader antitrust probe into Nvidia remains ongoing
What makes this case unusual is the target's public-good character. Unlike acquiring a chip designer or a cloud provider, Hugging Face's value rests on being neutral and open — major labs, startups and researchers publish and fetch models on the same platform. Whether the promises of "joint expansion and broader coverage" can ease regulators' concerns will depend on Nvidia demonstrating that platform governance will not tilt toward its own ecosystem.
For the industry, the case is a litmus test: the strategic resources of AI are extending from compute to distribution and community, and regulatory boundaries are moving with them. If the inquiry fades, Nvidia folds the world's most important open-source hub into its portfolio; if it escalates, the review standard for AI infrastructure deals gets rewritten. Until then, the developer community can only watch how a platform built on openness navigates its new owner.
