Reuters reported on October 29, 2026 that the Department of Justice has queried Nvidia's $13 billion acquisition of Hugging Face, asking whether ownership would give it control of a key distribution point for AI models. Sources say the antitrust investigation predates the Grok deal and extends beyond it, covering SketchMD, RunAI, venture investments and customer pressure. No charges have been filed, and the deal's fate remains open.
