Report: Arm faces antitrust investigation in the United States due to chip technology licensing.

The Federal Trade Commission of the United States is investigating whether SoftBank Group's Arm Holdings, a Japanese company, is attempting to illegally monopolize part of the semiconductor market by potentially refusing to license or reducing the quality of central processor licenses. The FTC's investigation is part of a global ongoing review of Arm's business. Regulatory agencies outside the United States are also investigating the company's conduct, including a lawsuit filed by Qualcomm against the European Commission. Arm is transitioning its business model to begin designing its own chips. While this move has been welcomed by some industry insiders, it has also raised concerns from Qualcomm that Arm may limit access to its technology.
