Masayoshi Son, CEO and founder of SoftBank, is significantly amplifying his investments in artificial intelligence (AI), underscoring his commitment to positioning SoftBank at the forefront of AI innovation. In collaboration with prominent tech leaders and organizations, Son has initiated substantial projects aimed at enhancing AI infrastructure and capabilities, particularly within the United States.

A pivotal development is the formation of a joint venture named "Stargate," announced on January 21, 2025. This partnership involves SoftBank, OpenAI, Oracle, and MGX, collectively committing up to $500 billion over the next four years to establish a network of AI-focused data centers across the U.S., starting in Texas. The initiative aims to bolster AI infrastructure, create approximately 100,000 jobs, and solidify the U.S.'s position in the global AI landscape.

This aggressive investment strategy reflects Son's long-standing belief in AI as a transformative force. Through the Vision Fund, SoftBank has previously invested in various tech companies, and Son has been a vocal proponent of AI's potential to revolutionize industries. The Stargate project exemplifies his approach of forming strategic alliances to drive large-scale technological advancements.

The announcement of the Stargate project has had significant market implications. Following the news, SoftBank's shares surged by 12%, indicating strong investor confidence in the company's strategic direction and its potential to capitalize on the burgeoning AI sector.

This highlights the competitive and sometimes contentious nature of the AI industry's evolution.
