Bloomberg reported on September 3, 2024, that the U.S. Department of Justice had sent subpoenas to Nvidia and other companies in an escalating antitrust investigation of Nvidia’s artificial-intelligence chip business. On September 4, Nvidia said it had contacted the DOJ and “have not been subpoenaed.” The contemporaneous record therefore supports an escalating DOJ information-gathering effort, but does not conclusively establish that Nvidia itself received a subpoena.
Reuters separately reported that investigators were asking technology companies about Nvidia’s hardware-bundling practices and examining its acquisition of Run:AI. The DOJ had not immediately commented in that reporting.
What happened, and when
- June 2024: Reports emerged that the DOJ was examining Nvidia’s powerful position in AI processors.
- August 2024: The Information reported that investigators had questioned Nvidia competitors and other industry participants.
- September 3, 2024: Bloomberg reported that the DOJ had escalated from questionnaires to subpoenas or other legally binding information requests involving Nvidia and other companies.
- September 4, 2024: Nvidia said it had asked the DOJ about the matter and had not been subpoenaed, while saying it would answer regulators’ questions.
- September 4, 2024: Reuters reported that DOJ questions covered hardware bundling and that investigators were examining Nvidia’s acquisition of Run:AI.
The dates matter: this was a September 2024 development, not a new August 2026 event.
Was Nvidia actually subpoenaed?
The answer depends on which contemporaneous account is being described. Bloomberg’s report said the DOJ sent subpoenas to Nvidia and other companies. Nvidia’s public response, reported by Reuters, was that it had inquired with the agency and “have not been subpoenaed.”

- A 2.5-slot design maximizes compatibility and cooling efficiency for superior performance in small chassis
Those statements can coexist if compulsory requests went to competitors, customers or other third parties, or if different reports used “subpoena” as a broad label for a civil investigative demand or another legally binding request. Without the underlying document, it is not possible to say that those legal terms were identical in this instance.
The precise, supportable formulation is: Bloomberg reported subpoenas in the Nvidia investigation; Nvidia denied receiving one; and the DOJ’s broader information-gathering effort appeared to be intensifying.
What conduct was reportedly under examination?
Exclusivity and switching
Reporting described questions about whether Nvidia made it harder for customers to move to competing AI-chip suppliers, or penalized buyers that did not use Nvidia chips exclusively. That is a reported investigative theory, not a finding that Nvidia violated antitrust law.

Hardware and systems bundling
Reuters said DOJ investigators were asking companies about Nvidia’s hardware-bundling practices. Nvidia sells GPUs alongside software, networking equipment, complete systems and related infrastructure. Bundling can provide compatibility, performance and support benefits. It can also draw scrutiny if a dominant supplier conditions access to a scarce product on buying additional products or makes meaningful customer choice impractical. The available reporting does not establish that Nvidia’s bundling was illegal.

Supply and pricing preferences
Bloomberg’s sources reportedly described concerns that Nvidia might favor customers that buy complete Nvidia systems, use its technology exclusively or operate ready-to-deploy data centers. Nvidia’s stated defense was that it wins on product performance and customer value, while customers remain free to choose other solutions. (Ars Technica)
Run:AI acquisition
Reuters reported that the DOJ was examining Nvidia’s acquisition of Israel-based Run:AI, reportedly valued at about $700 million in April 2024. Investigators were said to be considering whether the deal could further entrench Nvidia’s position by making it harder for customers to manage workloads across competing chips or platforms. A review is not the same as a challenge, blocked transaction or finding of illegality. (Reuters via Investing.com)

Why Nvidia’s position matters
Antitrust scrutiny is significant because Nvidia’s AI business combines several sources of customer dependence:
- High-demand data-center GPUs.
- CUDA and related software tools.
- Networking products and complete data-center systems.
- A large developer, cloud-provider and AI-company ecosystem.
Nvidia has reported an ecosystem of nearly 5 million developers, 40,000 companies and more than 1,600 generative-AI companies building on its technology. Those are company-reported ecosystem figures, not independent market-share measurements. (Nvidia’s 2024 annual report)

For regulators, the question is not simply whether Nvidia makes the best-performing product. They may also examine whether software compatibility, supply allocation, bundled systems or acquisitions raise rivals’ costs or make multi-vendor deployments unusually difficult.

What a subpoena or investigative demand means
A subpoena, civil investigative demand or similar compulsory request generally seeks documents, data, communications, interviews or other information. It does not mean the recipient has been charged, sued or found liable.
Moving from informal questions or questionnaires to compulsory requests can indicate a more formal evidence-gathering phase. It still does not establish that the DOJ will file a case. A formal complaint, court filing, consent decree or other enforcement action would be a separate later step.
Likewise, an antitrust probe is not an antitrust case, and a dominant position is not automatically an illegal monopoly. The eventual legal analysis would ordinarily consider the relevant market, Nvidia’s power in that market and whether specific conduct unlawfully excluded rivals or harmed competition.

What Nvidia says
Nvidia said it had contacted the DOJ, had not been subpoenaed and would answer regulators’ questions. Its stated position was that customers can choose the solutions that best meet their needs and that the company competes on the merit and value of its products. Those statements address the company’s position; they do not resolve the DOJ’s reported inquiry.
What could happen next?
- The DOJ could seek more documents, data or interviews from Nvidia and third parties.
- Investigators could close the inquiry without enforcement.
- The agency could negotiate behavioral remedies addressing supply, contracting, bundling or customer choice.
- It could challenge particular business practices or seek remedies involving an acquisition.
- The DOJ could file a civil antitrust complaint, leaving a court to decide whether Nvidia unlawfully maintained monopoly power or engaged in exclusionary conduct.
None of those outcomes was announced in the September 2024 reporting. A compulsory information request should not be treated as proof that charges are imminent.
What the story means for investors and AI buyers
The immediate, reliable fact is regulatory uncertainty around how Nvidia’s integrated hardware-and-software model will be assessed. Investors should distinguish that uncertainty from a proven violation or a guaranteed effect on Nvidia’s share price. AI companies and cloud providers, meanwhile, may watch for any remedy that changes access to chips, bundled systems, software tools or allocation policies.
The practical distinction is also important for customers: an investigation does not require Nvidia to make CUDA compatible with competing chips, and the reported material does not say that the DOJ has demanded such a change.
Bottom line
The DOJ’s Nvidia inquiry appeared to escalate in early September 2024. Bloomberg reported subpoenas involving Nvidia and other companies, but Nvidia said it had not received one. The investigation reportedly covered exclusivity, switching, bundling, supply and pricing practices, and the Run:AI acquisition. Until the DOJ announces a formal action or releases supporting documents, the subpoena claim about Nvidia itself remains disputed and the allegations remain unproven.
