Arm Just Debuted Its First In-House Chip. Should You Buy ARM Stock Now?

For more than 35 years, British chip designer Arm Holdings plc (ARM) has built its business on a simple but powerful model, licensing its instruction sets to some of the world’s biggest chipmakers, including Nvidia (NVDA) and Qualcomm (QCOM), and collecting royalties on every processor built using its designs. That approach has kept Arm at the center of the semiconductor industry without ever producing chips itself. Now, that is starting to change. 

On March 24, Arm investors received a major update when CEO Rene Haas unveiled the company’s first in-house chip at an event in San Francisco. The move begins with the launch of the Arm AGI CPU, an Arm-designed processor built specifically for artificial intelligence (AI) data centers. It is aimed at a new wave of agentic AI workloads and is designed to deliver more than 2x performance per rack compared with traditional x86 platforms.
