Arm Holdings plc (ARM) owns and develops the Arm processor architecture, which is used in 99% of the world's smartphone CPU cores and is also widely used in wearables, tablets, and sensors. Arm earns licensing fees and per-chip royalties. Customers such as Apple and Qualcomm buy architecture licenses that allow them to customize the design, while other customers license ready-made Arm chip designs. In 2026, Arm announced plans to launch its own CPU products in addition to its established licensing and royalty business.
