US DOJ questions Nvidia over Hugging Face acquisition

The significance here is less about the deal itself than about the DOJ treating AI's core infrastructure layer as an antitrust question — Nvidia's chips sit beneath the models, and Hugging Face's hub sits beneath the distribution of those models. That combination draws scrutiny over vertical reach rather than a single market share. For anyone building or investing in open-model tooling, the open question is whether this questioning stays a preliminary inquiry or becomes a formal review, since the latter would chill similar infrastructure acquisitions.
