Monday s 14% surge in Tokyo pushed Soft Bank s total market value to more than ¥48 trillion, leaving Toyota s roughly ¥46 trillion valuation behind. The last time SoftBank held this position was during the peak of Japan s internet bubble in 2000, according to Bloomberg.
Year to date, SoftBank s share price has nearly doubled, with gains exceeding 90% fueled largely by its growing footprint in the AI sector. Through a total commitment approaching $65 billion, SoftBank is on track to hold roughly a 13% ownership stake in OpenAI — the company behind ChatGPT — by October, according to Bloomberg. The run-up in SoftBank shares traces back to last month, when it emerged that portfolio holdings OpenAI and SB Energy Corp. were each eyeing potential listings on U.S. markets.
