The U.S. Justice Department is examining Nvidia's acquisition of Run:ai, a startup specializing in software for managing powerful computer components.
The probe follows reports of the Justice Department investigating Nvidia's leading position in the artificial intelligence chip market.
The investigation focuses on whether Nvidia bought Run:ai to stifle a technology that could limit the company's profits by making customers buy fewer of their chips.
Nvidia maintains that its success is based on the quality of its products and that they offer competitive solutions widely available to everyone.
