The US Department of Justice is investigating Nvidia's $12.93 billion acquisition of open-source AI platform Hugging Face, focusing on whether the deal could allow Nvidia to control a key AI distribution channel and suppress competitors. The inquiries form part of a broader multi-year conduct probe into Nvidia's acquisitions, investments, and sales practices, which also covers its purchases of SchedMD and Run:ai as well as a technology licensing agreement with Groq. Nvidia expects the Hugging Face acquisition to close in the first half of 2027. Both Nvidia and the DOJ declined to comment on the matter.
