Key Takeaways
  • • SoftBank CEO Masayoshi Son projects AI infrastructure will require $5 trillion in annual investment by 2040, or approximately 800 trillion yen, characterizing this spending as economically justified if AI generates 20% of global GDP.
  • • Son dismisses AI bubble concerns as "absurd," arguing critics fundamentally misunderstand the technology's transformational potential, which he claims is 50 times larger than the dot-com boom.
  • • SoftBank has committed tens of billions to AI infrastructure over the past two years, including major investments in OpenAI, data center financing, and robotics firms, positioning the group as a core AI platform provider.
  • • Son plans to deploy AI agents at $0.23 per month (approximately 230 euros per 1,000 agents) to replace human programmers, reflecting confidence in AI's cost-reduction economics and operational viability.
  • • The CEO indicated willingness to remain active into his 70s pursuing AI ambitions and suggested market corrections would present attractive investment opportunities rather than indicators of systemic overvaluation.
Summary
SoftBank Group CEO Masayoshi Son made sweeping projections about artificial intelligence infrastructure spending and vigorously defended the sector against bubble accusations at the company's annual corporate conference in Tokyo on July 14, 2026. Son stated that developing AI will require $5 trillion in annual investment by 2040—equivalent to 800 trillion yen—a figure he acknowledged may seem implausible but defended as economically rational. He anchored this projection to an assumption that AI will represent 20% of global GDP by 2040, rendering such spending "a rounding error" relative to expected economic value creation.

The SoftBank leader characterized criticism of an AI bubble as fundamentally ignorant, declaring such questions "absurd" and suggesting that skeptics lack basic understanding of AI's scope and transformational potential. Son positioned the current AI revolution as 50 times larger than the dot-com boom of the early 2000s, though he did not detail the methodology underlying either his spending projections or GDP assumptions. This aggressive stance reflects SoftBank's substantial capital deployment: the technology investment group has committed tens of billions to AI infrastructure over the past two years, including major stakes in OpenAI, data center financing, and robotics investments.

Son's rhetoric carries particular weight given his historical track record. His early investment in Chinese e-commerce firm Alibaba generated substantial returns, and his strategy of bringing Apple's iPhone to the Japanese mobile market proved strategically significant. However, his portfolio also includes notable failures, such as bankrupt shared-office provider WeWork, which underscores the execution risks inherent in transformational technology bets. Industry observers have raised legitimate questions about whether high-valuation AI firms will generate sufficient returns on accelerating capital expenditure, but Son dismissed such concerns as fundamentally misguided.

The CEO indicated personal commitment to realizing his AI vision, stating he would continue working into his 70s to pursue these ambitions. He also suggested that market corrections, should they occur, would represent buying opportunities rather than indications of overvaluation, reflecting his conviction in long-term AI economic fundamentals. Son's confidence in AI-driven cost reduction was evidenced by his discussion of deploying AI agents at $0.23 per month per agent, positioning workforce automation as a near-term competitive advantage across industries.
