The reported subjects included Nvidia’s acquisition of AI-computing software company Run:ai, whether customers faced difficulty switching suppliers, and whether Nvidia disadvantaged buyers that used competing chips. Nvidia said it had not been subpoenaed, making the legal form of the requests an important qualification.
What was reported
The report described an ongoing DOJ antitrust inquiry, not a filed lawsuit or a finding that Nvidia violated the law. According to coverage carried by CRN and attributed to Bloomberg, investigators sent additional information demands after earlier inquiries into Nvidia’s AI-chip business.
The reported focus was Nvidia’s position in AI accelerators and related products, including the Run:ai transaction. The allegations and investigative theories were not established findings.
Information request, subpoena, complaint: why the labels matter
| Term | What it means here |
|---|---|
| Information request | A demand for documents or answers while officials gather facts. It is the safest description when the exact legal instrument is unclear. |
| Civil investigative demand | A formal compulsory investigative tool. The available reporting does not independently establish that this was the instrument used in every request. |
| Subpoena | A legally enforceable demand, but the term was disputed in this episode. Bloomberg-based reporting described legally binding requests, while Nvidia said it had not been subpoenaed. |
| Antitrust complaint | A formal enforcement pleading. No publicly filed DOJ complaint against Nvidia was identified in the sources reviewed. |
| Judgment or order | A court or agency resolution. None was established by the September 2024 report. |
Techmeme’s account of the Bloomberg report recorded Nvidia’s position that it had contacted the Justice Department and had not received a subpoena. A company can dispute that label without denying all contact with investigators; journalists and lawyers may use different terms depending on the document involved.

What investigators were reportedly examining
Switching away from Nvidia
One reported question was whether Nvidia made it difficult for customers to move to other AI-chip suppliers. Nvidia’s influence extends across accelerators, software, systems, networking and developer tools. That integrated ecosystem may raise switching costs, but ecosystem strength or customer preference alone is not proof of unlawful monopolization.
Purchasing non-Nvidia chips
Investigators were also reportedly examining whether Nvidia penalized, restricted or otherwise disadvantaged customers that bought competing chips instead of purchasing exclusively from Nvidia. Whether conduct is unlawful would depend on the contracts, incentives, market definition and competitive effects, none of which were resolved in the report.
The Run:ai acquisition
Run:ai develops software for managing AI computing. The DOJ reportedly sought information about Nvidia’s acquisition of the company as part of its broader inquiry.

Why Nvidia’s market position drew scrutiny
Nvidia supplies widely used AI accelerators and the software stack that helps developers and data-center operators deploy them. Hardware, programming tools, networking and complete systems can reinforce one another and make migration costly or technically difficult. Antitrust law does not prohibit a company from winning through better performance, investment, scale or integration. The legal question would be whether Nvidia possessed relevant market power and used exclusionary conduct rather than simply competing successfully.
What a DOJ case would generally need to show
- A properly defined product and geographic market.
- Substantial market power in that market.
- Exclusionary or otherwise unlawful conduct, such as certain forms of exclusive dealing, retaliation, tying or discriminatory access.
- Competitive harm that is not explained solely by legitimate product advantages or normal business efficiencies.
The September 2024 reporting did not say the DOJ had reached those conclusions.
Run:ai’s separate European merger timeline
The Run:ai deal later entered a formal European Union merger process, which was distinct from the U.S. conduct inquiry.
Rank #3
- Powered by the NVIDIA Blackwell architecture and DLSS 4. System Requirements: Minimum 850W PSU with 16-pin 12V-2x6 (12VHPWR) connector required. Verify before purchasing.
- Military-grade components deliver rock-solid power and longer lifespan for ultimate durability. Compatibility: 348mm (13.7") length, 3.6 slots, 4.3 lbs. Confirm case clearance and slot spacing. GPU bracket included.
- Protective PCB coating helps protect against short circuits caused by moisture, dust, or debris
- 3.6-slot design with massive fin array optimized for airflow from three Axial-tech fans
- Phase-change GPU thermal pad helps ensure optimal thermal performance and longevity, outlasting traditional thermal paste for graphics cards under heavy loads
- November 15, 2024: The European Commission received notification of the proposed transaction, recorded in the EU merger register.
- December 20, 2024: The Commission approved the acquisition unconditionally in its decision and related press release.
That decision addressed the notified concentration under EU merger rules. It was not a blanket clearance of Nvidia’s business practices and did not decide separate U.S. questions about customer switching or purchasing conditions.
How other regulators fit into the story
The DOJ inquiry appeared amid broader scrutiny of AI markets and technology partnerships. The Federal Trade Commission sought information from major technology companies about AI investments and partnerships. The U.K. Competition and Markets Authority examined Microsoft’s relationship with Inflection, while European authorities reviewed AI-related transactions and market behavior. China later opened a separate antitrust investigation into Nvidia, according to contemporaneous reporting; that proceeding should not be treated as evidence for the DOJ’s theories.

Different authorities apply different legal standards and may examine different conduct. Antitrust scrutiny should also be kept separate from Nvidia’s export-control and national-security issues involving China.

What the September 2024 report did—and did not—establish
- It reported additional DOJ information demands concerning Nvidia’s AI-chip practices and the Run:ai deal.
- Nvidia said it had not been subpoenaed, so “subpoena” should not be presented as an uncontested fact.
- The report did not establish liability, a DOJ charge, a lawsuit, or an order requiring Nvidia to change its practices.
- No definitive public DOJ complaint or final judgment was identified in the sources reviewed.
- EU approval of Run:ai did not resolve every possible U.S. or international antitrust issue.
Status update as of August 18, 2026
Reported in September 2024: DOJ investigators sought additional information about Nvidia’s AI-chip business, customer purchasing and Run:ai.
Nvidia’s position: The company said it had not been subpoenaed and was in contact with the DOJ.
Run:ai: The European Commission approved the acquisition without conditions on December 20, 2024.

Public resolution: The reviewed sources do not identify a definitive DOJ complaint, judgment or closure of the reported inquiry. Nvidia’s fiscal 2026 Form 10-K, filed February 25, 2026, continues to describe regulatory, competition and litigation risks, but it does not provide a final resolution of this 2024 matter. The filing is available through the SEC.
What could happen next in an inquiry like this
Investigators could request more documents, interview employees or customers, negotiate remedies, close the matter without action, or file a civil complaint. A complaint could lead to settlement, behavioral restrictions, litigation and judicial review; structural relief would require additional legal and factual steps. These are possible procedural paths, not reported outcomes in Nvidia’s case.
Frequently Asked Questions
Was Nvidia charged by the DOJ in September 2024?
No. The reporting described an antitrust inquiry and additional information demands, not a filed DOJ charge or court case.
Did Nvidia receive a subpoena?
Bloomberg-based coverage described legally binding requests, while Nvidia said it had not been subpoenaed. The precise legal instrument was therefore disputed.
