SoftBank Group will be the first to build a supercomputer with chips using Nvidia’s new Blackwell design, a demonstration of the company’s ambitions to catch up on artificial intelligence.

SoftBank’s telecom unit plans to build Japan’s most powerful AI supercomputer to support a wide range of local services, the two companies said. That computer will be based on Nvidia’s DGX B200 product, which combines computer processors with what are known as AI accelerator chips. A follow-up effort will feature Grace Blackwell, a more advanced version.

Shares of SoftBank, Japan’s No. 3 wireless carrier, reversed losses and rose 1.5% Wednesday. SoftBank Group, which comprises the conglomerate’s investment teams, fell as much as 3.3%.
