SoftBank Group has reported a significant surge in its quarterly profits, largely attributed to the increased valuation of its investment in OpenAI. The company announced a net profit of ¥1.83 trillion ($11.6 billion) for the fourth fiscal quarter, far exceeding the analyst forecast of ¥295.2 billion. This boost comes despite market disruptions from Middle East conflicts and declining share prices of key holdings like Coupang and Grab Holdings. The valuation increase in OpenAI contributed to a cumulative unrealized gain of $45 billion as of March 31. SoftBank's founder, Masayoshi Son, has been actively selling shares and increasing debt to fund AI investments. Son plans to elevate SoftBank's total investment in OpenAI to $64.6 billion by the end of the year, alongside ambitious data center projects.
