SoftBank is going all in on AI.

Just months after announcing its involvement in the $500 billion Stargate AI Infrastructure project, of which SoftBank is rumored to be fronting a cool $19 billion, the Japanese investing conglomerate is reportedly looking to launch its largest AI project yet.

The company is looking to team up with Taiwan Semiconductor Manufacturing Company (TSMC) to launch a trillion-dollar industrial complex in Arizona to build AI and robotics, according to reporting from Bloomberg, citing sources familiar with the project.

The initiative, dubbed Project Crystal Land, appears to still be in its very early stages. Despite SoftBank’s desire to work with TSMC on the project, it’s unclear what TSMC’s role would be, according to Bloomberg, or if it would be interested in joining forces with SoftBank at all — TSMC already has its own AI infrastructure projects in Arizona in the works.
