SoftBank CEO Projects Massive AI Infrastructure Investment

At SoftBank's annual conference in Tokyo on Tuesday, CEO Masayoshi Son made a bold projection that has sent ripples through the technology and financial sectors. The veteran technology investor estimates that AI demand will require $5 trillion a year needed in global investment by 2040 to support data centers, chip production, energy systems, and other critical AI infrastructure

1

. "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," Masayoshi Son declared to executives gathered at the event

1

. While Son did not reveal the methodology behind this staggering figure, he justified it by predicting that AI-related industries will constitute approximately 20% of global GDP by 2040, making the annual expenditure "a rounding error" in comparison to projected revenues

Dismissing AI Investment Bubble Concerns

Son took direct aim at critics questioning whether an AI investment bubble is forming, calling such concerns "absurd" and "a foolish question"

2

. "I don't think people who ask that question know what AI is about," he stated emphatically

1

. Going further, Son derided doubts as backward, comparing them to questioning the use of cars and planes, and declared that "those who condemn AI are themselves spitting upward"

4

. This forceful rhetoric comes as financial markets grapple with concerns about whether massive investments in companies like Nvidia and data centers will yield returns matching profit expectations

5

. SoftBank itself has embarked on an expansive two-year investment program, pouring tens of billions into OpenAI, financing data centers, and backing robotics firms to establish itself as a core AI platform rather than merely an investor

OpenAI Investment and SoftBank's AI Bet

SoftBank's highest-conviction wager centers on ChatGPT-maker OpenAI, with cumulative investment set to exceed $60 billion before 2026 ends

1

. The tech giant has already invested $34.6 billion in OpenAI and sold its stake in semiconductor production leader Nvidia last year to free up funds for more investments in AI and data centers

2

. This concentration of capital reflects Son's belief that AI will transform global industries completely and generate substantial profits

4

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

5

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

.

Energy Systems and Nuclear Fusion Vision

Addressing the massive power requirements for AI infrastructure, Son predicted that AI data centers will need power generation of 3 terawatts by 2040, equal to 1.8 times total current global power consumption

1

. This energy will initially be powered primarily by gas before nuclear fusion becomes the main energy source, Son said

1

. When asked about alternatives like space-based solar power, Son responded: "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"

3

. This forecast relies on nuclear fusion becoming a commercial power source, though it is not yet operational anywhere on earth

.

Vision for Agent-Centric Society

Son outlined an ambitious vision of society in 2040 where 100 trillion autonomous AI agents make their own decisions, take action, and communicate with other agents without human intervention

1

. "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

3

. This prediction of an agent-centric society represents a fundamental shift in how Son envisions technology reshaping civilization. None of his three major predictions regarding investment needs, energy systems, or autonomous AI agents came with detailed models or methodology

3

. Son, who founded SoftBank more than four decades ago and is a pioneer in Japan's technology investments, has asked for another decade to see his thesis through at age 68

3

. His track record includes major wins with early investment in Chinese e-commerce firm Alibaba and bringing Apple Inc's iPhone to the Japanese mobile phone market, but also failures like bankrupt shared-office provider WeWork
