Masayoshi Son's return to the summit of Asia's wealth rankings lasted a mere 72 hours, a fleeting reign that serves as a stark microcosm of his volatile career. As SoftBank Group’s stock plunged 17% over three days, erasing $13.2 billion from his personal net worth, the narrative shifted from a triumphant comeback to a familiar warning about the fragility of AI-driven valuations. The Japanese billionaire now finds himself trailing behind India’s industrial titans, Mukesh Ambani and Gautam Adani, as the market recalibrates its enthusiasm for his aggressive 'All in AI' strategy.
This recent correction is inextricably linked to SoftBank’s massive pivot toward generative AI, characterized by a series of staggering capital commitments. Over the past year, Son has directed more than $60 billion into OpenAI and signaled intentions to invest up to $85 billion in a massive 5GW computing cluster in France. Son maintains that the AI revolution will dwarf the internet era by a factor of ten or even fifty, a conviction that drives him to seek what he calls 'the legendary' rather than mere incremental profits.
However, this singular vision is breeding internal discord within SoftBank’s upper echelons. Reports suggest that senior executives are increasingly uneasy with Son’s perceived 'fan-like' devotion to OpenAI CEO Sam Altman, a relationship some fear has become a one-way dependency. When subordinates have attempted to raise questions regarding the risks of such concentrated exposure, Son has reportedly dismissed them with growing impatience, leading to a chilling effect on internal dissent.
External critics are equally vocal, drawing parallels between today’s AI fervor and the dot-com bubble of the late 1990s. Economists at the Nomura Research Institute warn that if the economic benefits of AI fail to meet the market’s stratospheric expectations, the current rally could face a systemic collapse. For Son, who famously lost 90% of his fortune when the first internet bubble burst, these warnings are historical echoes he has chosen to ignore in favor of chasing the next technological frontier.
Son’s legacy is a polarizing patchwork of brilliant foresight and catastrophic miscalculation. While his $20 million early bet on Alibaba remains one of the most successful venture investments in history, the ghost of the WeWork collapse still haunts his portfolio. Having once called WeWork a 'monster' of his own making, Son appears undeterred by past failures, viewing market corrections as minor footnotes in a century-long trajectory toward Artificial General Intelligence (AGI).
