The investment business segment at SoftBank reported an investment gain of Y363.9bn for the period, primarily reflecting Y354.4bn from the disposal of Nvidia shares.

It noted that proceeds from the Nvidia share sale would be directed toward its AI initiatives. These include the planned $500bn Stargate project aimed at expanding data centre capacity in the US and up to $40bn pledged for investments in OpenAI.

Last month, SoftBank amended its agreement with OpenAI to allow a full additional investment of $22.5bn, regardless of whether certain conditions were met.

The Japanese group later confirmed it would make this investment through its SoftBank Vision Fund 2 in December 2025.

Alongside the divestment from Nvidia, SoftBank disposed of approximately $9.2bn in T-Mobile shares to further support funding for its AI-related projects and investments.

In a separate development, Nvidia announced plans with South Korea’s Ministry of Science and ICT to expand AI infrastructure across sovereign clouds and factories using more than 250,000 graphics processing units (GPUs).

This initiative includes deploying up to 50,000 new Nvidia GPUs for enterprises and industries and establishing South Korea’s National AI Computing Center with contributions from local cloud partners.

Separately, Samsung Electronics and Nvidia will collaborate on a new semiconductor “AI factory” powered by more than 50,000 GPUs.

This facility aims to integrate accelerated computing into advanced chip manufacturing processes for Samsung.

Recently, Nvidia joined forces with Deutsche Telekom to announce the launch of the Industrial AI Cloud, a €1bn ($1.2bn) AI infrastructure initiative, which is scheduled to go live in early 2026.

Developed through a strategic partnership between the two companies, the platform will offer organisations in Germany and across Europe access to substantial computing power for AI applications.
