SoftBank Group's shares surged more than 16% on Thursday, driven by robust earnings from Nvidia that underscored the growing momentum in the artificial intelligence sector.
The Japanese conglomerate holds a significant stake in Arm Holdings, a key player in chip design for AI servers and data centers, which are increasingly powered by Nvidia's systems.
The market reaction highlights the interconnectedness of semiconductor firms and AI infrastructure providers.
Nvidia's results have reinforced investor confidence in the broader AI ecosystem, with SoftBank's exposure to Arm amplifying its gains.
The stock's sharp rise reflects the sector's current focus on AI-driven growth and the potential for continued expansion in data-center demand.
This development follows recent moves by SoftBank to capitalize on the AI boom, including plans to spin off a standalone AI and robotics company named Roze.
