FTC Sues to Block Nvidia's $40 Billion Acquisition of Arm

The Federal Trade Commission sued to block Nvidia’s $40 billion acquisition of a fellow chip company, Arm, halting what would be the biggest semiconductor industry deal in history, as federal regulators push to rein in corporate consolidation. The FTC said the deal between Nvidia, which makes chips, and Arm, which licenses chip technology, would stifle competition and harm consumers.
