SoftBank Group Shares Rise After Arm Unveils Plans to Sell Its Own Chips
By Kosaku Narioka
SoftBank Group shares rose sharply after its unit Arm Holdings unveiled a plan to sell its own computer chips, raising hopes for another stream of revenue at the chip-designer.
SoftBank shares were recently 7.5% higher at 3,795 yen, equivalent to $23.91, on Wednesday in Tokyo, after rising as much as 8.6% earlier.
The moves come after Arm said Tuesday it will sell a central processing unit it designed for use in artificial-intelligence data centers, expanding into silicon products for the first time.
The U.K.-chip designer said Meta is the lead partner and co-developer of the central processor. Other committed customers include OpenAI, Cloudflare and SAP, Arm Chief Executive Rene Haas said.
Arm said its chips help deliver faster computation and reduce capital expenditures for AI data centers. The chip-designer said the rise of AI agents requires significantly more central processing units to handle reasoning, coordination and data movement.
SoftBank Group held an 87% stake in Arm as of the end of March 2025. The stake is one of the Japanese technology investor's most valuable holdings.
