Masayoshi Son
Venture capitalist betting on humanity's next inflection point with a 300-year vision and AI singularity conviction
Masayoshi Son founded SoftBank in Fukuoka in 1981 and used his 'Time Machine Theory' to transplant American internet models to Japan and Asia. His early investments in Yahoo Japan and Alibaba created one of the highest investment returns in history. During the dot-com bubble he lost approximately $98 billion in paper wealth—the largest personal wealth destruction ever recorded—yet avoided bankruptcy and rebuilt. In 2017 his $100 billion Vision Fund fundamentally changed global tech investment, making mega-scale bets on Uber, WeWork, ARM, and others. He views AI singularity—the moment artificial intelligence surpasses human intelligence—as the greatest inflection point in human history and has restructured SoftBank's entire strategy around this conviction. His investment philosophy is built on extreme long-termism and belief in technological paradigm shifts, willing to accept short-term massive losses for long-term outsized returns.
Methodologies
- Time Machine Investment Execution Method - Systematically identify proven success models in leading markets and rapidly transplant them to lagging markets within the time lag window for high-certainty returns at lower risk.
- 300-Year Vision Decision Filter - When making major strategic decisions, use a 300-year timescale to filter short-term noise and focus on opportunities that can truly change the trajectory of human civilization.
Key decisions and timeline
- 1981-09 Founded SoftBank in Fukuoka, declared grand vision standing on apple crates - Setting goals within timescales others consider impossible forces teams to think and act in completely different ways.
- 1995-11 Invested in Yahoo and brought the internet model to Japan - In the early stages of technological paradigm shifts, speed matters more than perfect analysis; the Time Machine Theory provides a repeatable investment framework.
- 1999-10 Decided to invest $20 million in Alibaba in 6 minutes - Judgment of people is sometimes more important than analysis of business models; true visionaries can often make correct judgments when data is insufficient.
Beliefs and mental models
- Belief 1 - Son believes truly ambitious companies should not think in quarters or years but in centuries. He created a 300-year corporate vision for SoftBank, positioning it as infrastructure for humanity's information revolution rather than an ordinary tech company. This conviction makes him willing to accept short-term massive losses, as on a 300-year timescale these are merely minor fluctuations.
- Belief 2 - Son deeply believes the 'singularity' where artificial intelligence surpasses human intelligence will arrive within this century—a transformation more profound than the Industrial Revolution. He has bet all of SoftBank's resources on this conviction, believing that missing the AI singularity means missing the next phase of human civilization. He has publicly stated that AI will make human intelligence look insignificant, and companies that master AI will dominate the future.
- Belief 3 - Son believes different countries have a time lag in internet development—the US leads Japan by about 2 years, Japan leads China by about 2 years. Therefore one can find proven business models in the US and transplant them to other markets within the time lag window, achieving near-certain success. This theory drove his early investments in Yahoo Japan, Alibaba, and similar companies.
