The Japanese conglomerate is currently negotiating terms with Nvidia after receiving an approach last month, the report said, citing an unidentified source familiar with the matter, adding that it is possible that SoftBank would take stake in Nvidia after it bought Arm.

The report did not mention how much stake the company will retain in Arm.

SoftBank did not respond to a Reuters request for comment.

The Wall Street Journal reported last month that SoftBank was exploring options including a full or partial sale or public offering of Arm.

SoftBank acquired the British chip designer for $32 billion in 2016, its largest-ever purchase, in part to expand into the internet of things, which connects everyday devices from traffic signals to refrigerators to the internet.

In March, it unveiled a 4.5 trillion yen ($42.50 billion) plan to buy back shares and reduce debt.

Under the plan the group has been selling down core assets including stakes in Chinese ecommerce giant Alibaba Group Holding and U.S. wireless carrier T-Mobile US Inc.

A sale would not be part of group's asset monetization program, Nikkei reported.
