SoftBank CEO Masayoshi Son declared that AI will need $5 trillion per year by 2040 and dismissed bubble concerns as absurd at the company's annual conference in Tokyo. With over $60 billion invested in OpenAI, Son outlined a future where AI-related industries constitute 20% of global GDP and 100 trillion autonomous AI agents reshape society into an agent-centric world.

SoftBank CEO Masayoshi Son Defends Massive AI Investment Amid Bubble Concerns

At SoftBank's annual corporate conference in Tokyo, CEO Masayoshi Son delivered a bold proclamation that AI will need $5 trillion per year by 2040, while simultaneously dismissing concerns about an AI bubble as "absurd."

1

The declaration comes as SoftBank Group has embarked on an expansive two-year AI investment program, pouring tens of billions into OpenAI, financing data centers, and investing in robotics firms to establish itself as a core AI platform. Son's cumulative investment in ChatGPT-maker OpenAI is set to exceed $60 billion before 2026 ends, representing one of the most concentrated bets in the technology sector.

The $5 Trillion Question and AI's Transformative Potential

"Every year $5 trillion, or 800 trillion yen, you might think that's a lie, but I am confident that's what it will cost," Son told executives, though he did not explain how he arrived at this figure.

3

His justification centered on proportion rather than arithmetic: "The business model will be viable because by 2040, if AI revenue makes up 20% of global GDP, spending 800 trillion yen a year is a rounding error."

This massive AI demand would require annual global investments to expand data centers, increase chip production, and provide energy systems and other AI infrastructure.

Dismissing AI Bubble Fears as "Foolish"

"To ask whether AI is a bubble is a foolish question," Son told the Tokyo audience. "AI will transform our lives completely, and do so in a way that generates profits. Those who refuse to evolve are closing down their world. Those who condemn AI are themselves spitting upward."

He added that people who question whether there's an AI bubble "don't think people who ask that question know what AI is about."

This isn't the first time Son has rejected such concerns—he previously called bubble talk "blasphemy against AI."

SoftBank's AI Investments Face Credit Rating Pressure

SoftBank's aggressive AI investment strategy has attracted scrutiny from credit rating agencies. S&P Global downgraded SoftBank's outlook from "neutral" to "negative" in March, warning that "the liquidity of SoftBank Group's investment portfolio will worsen because OpenAI now accounts for a bigger share of it."

The ratings agency estimated that the additional investment in OpenAI would knock nearly four percentage points onto the company's loan-to-value ratio. SoftBank has invested $34.6 billion in OpenAI and sold its stake in chip maker Nvidia last year to free up funds for more investments in AI and data centers.

Energy Demands and Nuclear Fusion Vision

Son predicted that AI data centers will require power generation of 3 terawatts by 2040, equal to 1.8 times total current global power consumption.

1

These energy demands will initially be powered primarily by gas before nuclear fusion becomes the main energy source, according to Son's vision. "Will we use solar power in space as Elon Musk says? Maybe we will use both, but if you ask me fusion on earth will be the cheaper, cleaner energy source," he stated.

SoftBank recently started a battery business in Japan to build next-generation electric power infrastructure in anticipation of growing electricity demand driven by AI use.

Vision of an Agent-Centric Society and AI Superintelligence

Son outlined his vision of society in 2040 where 100 trillion autonomous AI agents make their own decisions, take action, and communicate with other agents. "We will go from a human-centric world to an agent-centric world. The age when humans are the highest life form on earth will end. For better or for worse, it will happen and it can't be stopped," Son declared.

He referenced AI superintelligence as the defining characteristic of AI-related industries that would comprise a fifth of global GDP.

Financial Viability and SoftBank's Track Record

Son made his name through big bets on transformational technologies, scoring major wins with an early investment in Chinese e-commerce firm Alibaba and bringing Apple Inc's iPhone to the Japanese mobile phone market. However, others like bankrupt shared-office provider WeWork failed to live up to the hype.

1

Tokyo-based SoftBank Group reported its profits for the fiscal year through March soared nearly five-fold to 5 trillion yen ($32 billion) from a year earlier as its AI investments paid off.

SoftBank oversees a sprawling collection of businesses through what it calls Vision Funds, with other businesses including telecommunications and energy.
