Masayoshi Son is the founder and Chief Executive Officer of SoftBank Group Corp., the Japanese multinational technology investment holding company he established in 1981. He is best known for building one of the world's largest technology investment portfolios, including an early bet on Alibaba that became one of the most profitable venture investments in history. Son has positioned SoftBank at the forefront of artificial intelligence investing, committing tens of billions of dollars to AI infrastructure and companies including OpenAI, and has pursued major U.S. data center acquisitions as part of that strategy. He operates as the group's primary strategic decision-maker, setting direction on large-scale bets while delegating operational execution.
