Key Takeaways
- • SoftBank Group is mobilizing cumulative investments in OpenAI expected to reach approximately ¥10 trillion ($62.7 billion), securing an estimated 13% ownership stake as part of a vertically integrated AI dominance strategy.
- • Arm, SoftBank's semiconductor design subsidiary, is launching a new data center CPU called "AGI CPU" while the parent company plans large-scale data center construction in the United States to control the full AI infrastructure stack.
- • Masayoshi Son, SoftBank Chairman and CEO, declared at the April 1, 2026 group-wide new employee ceremony that the company aims "to be at the center of the AI revolution" and "become number one" over the next 30 years.
- • Son identified the core AI revolution framework as encompassing three elements: chips, AI models running on them, and interconnected data centers across hundreds of millions or billions of nodes to function as "formidable brains."
- • SoftBank projects that only approximately ten companies will play central roles in the global economy during the AI era, positioning itself as a strategic competitor across semiconductors, AI models, and infrastructure layers.
Summary
SoftBank Group is executing an aggressive, capital-intensive strategy to achieve dominance across the artificial intelligence value chain. The company's cumulative investment commitment in OpenAI is expected to reach approximately ¥10 trillion (roughly $62.7 billion), positioning SoftBank with an estimated 13% ownership stake in one of the world's leading AI model developers. This investment represents a foundational element of a broader vertically integrated approach spanning semiconductors, software, and infrastructure.
Chairman and CEO Masayoshi Son articulated the company's ambition during SoftBank's April 1, 2026 group-wide new employee ceremony, stating explicitly: "For the next 30 years, we aim to be at the center of the AI revolution. I wish to become number one." Son outlined a three-pillar framework for AI dominance: semiconductor chips, the artificial intelligence models that execute on them, and interconnected data center infrastructure linking hundreds of millions or billions of nodes to create what he described as "formidable brains." This layered approach reflects a conviction that controlling multiple nodes of the AI infrastructure stack is essential for competitive advantage.
On the semiconductor front, SoftBank's subsidiary Arm is launching a specialized data center CPU branded "AGI CPU," designed specifically for artificial general intelligence applications. Simultaneously, SoftBank is undertaking large-scale data center construction projects in the United States, signaling significant capital deployment in physical infrastructure to support AI workloads and model training at enterprise scale.
Son's strategic assessment emphasizes scarcity at the top tier of the AI economy. He projected that "only about ten companies will come to play a central role in the global economy" as the AI revolution matures, framing SoftBank's investments as a bet on inclusion within this elite cohort. The execution phase of this multi-layered investment strategy is now underway, backed by substantial capital mobilization across multiple business lines.
