Asia Tech Wire (Sep 4) -- The U.S. Department of Justice issued a subpoena to Nvidia over antitrust concerns, according to Bloomberg.

The DOJ has issued subpoenas to Nvidia and other companies seeking evidence that the U.S. chipmaker violated antitrust laws, the report said, citing sources.

Antitrust officials are concerned that Nvidia is making it harder for customers to switch to other suppliers and penalizing buyers who don't specifically use its AI chips.

In response, Nvidia spokesperson John Rizzo said the company's merit is reflected in its results and value to customers, "who can choose whatever solution is best for them."
