Semafor: The U.S. Department of Justice is investigating Nvidia for antitrust concerns, with no indication it is seeking criminal charges against Jensen Huang
According to a report by U.S. financial media outlet Semafor on 2026-11-12, two government officials said the U.S. Department of Justice has multiple investigations that could involve Nvidia, including one focused specifically on the chipmaker itself on antitrust grounds.
The other two investigations target technology companies Megaspeed and Supermicro, focusing on the involvement of Alice Huang, who is alleged to be a Chinese spy; Jensen Huang admitted to having an extramarital affair with her before his resignation. Semafor said there is currently no indication that the Justice Department will seek criminal charges against Nvidia or Huang.
Nvidia and a Justice Department spokesperson did not comment to Semafor; Megaspeed and Supermicro did not immediately respond to requests.

The Justice Department’s antitrust review of Nvidia did not begin today. As early as 2024, the DOJ had opened investigations into Nvidia’s dominance in the AI chip market (with multiple parties at the time estimating a data center AI GPU share of more than 80%), its supply and pricing behavior toward customers (such as whether it imposed restrictions on buyers of competing chips or bundled networking equipment), and its roughly $700 million acquisition of GPU management software company Run:ai, and the inquiry was escalated to a civil investigative demand. Later reports also involved questions about Groq licensing deals and Hugging Face’s acquisition intentions, with the investigation spanning both the Biden and Trump administrations.
This report places the antitrust probe alongside the political fallout after Huang’s resignation, while the Megaspeed/Supermicro investigations center on export controls and China-related channels. Nvidia’s core advantage has long rested on the CUDA software ecosystem, full-system bundling, and preferential supply allocation, all of which are potential sources of lock-in effects that regulators scrutinize. As founder and long-time CEO, Huang’s personal network and customer relationships had been seen by the market as an irreplaceable source of pricing and allocation power; after his departure, Colette Kress took over as interim CEO, and the board appointed a chair for the first time, shifting the company’s power structure from highly personalized to more institutionalized.
Compared with the antitrust cases against Microsoft and Google, regulators often begin with information requests and conduct reviews, with formal lawsuits or settlements only possible years later; Nvidia’s case is similar and is currently still at the stage of there being an investigation but no charges. Unlike those cases, the AI chip market is growing very quickly, absolute shipments continue to expand, and a decline in share may not immediately weaken absolute dominance; however, the regulatory focus is shifting from whether there is dominance to whether dominance is being used to restrict switching or bundling.
Huang’s departure reduces the concentration of key-person risk in policy lobbying and customer relationships, but it does not automatically end existing investigations. The antitrust path depends more on evidence of the company’s overall conduct (supply allocation, bundling terms, acquisition structure) than on a single CEO. If the investigation advances to formal charges, it may seek behavioral remedies (such as open interfaces or bans on exclusive arrangements) rather than a direct breakup; indicators to watch include whether there are escalated compulsory information requests or public signs of third-party customers testifying.

Antitrust investigations focus on company conduct and lock-in effects, not on whether the founder is still in office.
Personal-relationship risk can trigger a resignation, but the regulatory path still proceeds along existing market-structure evidence.
