Masayoshi Son has made a stunning comeback, largely thanks to his strategic investments in the realm of artificial intelligence (AI). As of September 25, 2025, his personal fortune has soared by a staggering 144%, reaching $38.7 billion. This marks the highest point his wealth has hit since the Bloomberg Billionaires Index started keeping tabs in 2013. Earlier, Son faced a significant setback owing to investment blunders, such as his involvement with WeWork. However, he managed to turn the tide by making well-calculated moves in the AI sector. This included leveraging ARM's chip architecture, investing in OpenAI, and constructing AI data centers. (Here, “strategic layout” is kept as descriptive text to convey the essence of Son's calculated and forward-thinking approach in the AI domain, akin to a strategic positioning that sets the stage for success.)
