The U.S. Justice Department is looking into Nvidia's purchase of Run:ai, a company that makes software to manage graphics card clusters.
This investigation comes after reports of the Justice Department probing Nvidia's dominance in the artificial intelligence chip market.
The focus of the investigation is whether Nvidia acquired Run:ai to stifle a technology that could hurt its profits, potentially leading customers to buy fewer of its chips.
Nvidia maintains that the company's success is based on merit and that its products are widely available and competitive in the market.
