Summary

SoftBank Group, under CEO Masayoshi Son, is aggressively pursuing a $22.5 billion investment in OpenAI by year-end, positioning itself as a key player in the AI race. To fund this ambitious bet, SoftBank has sold significant stakes in Nvidia ($5.8 billion) and T-Mobile US ($4.8 billion), and may leverage undrawn margin loans against its Arm Holdings ownership, alongside other capital sources like cash reserves and potential IPOs such as PayPay. This investment, initially made at a $300 billion valuation for OpenAI, could yield substantial gains as the startup's valuation approaches $900 billion. The funds are vital for OpenAI's escalating costs in AI model training and projects like the $500 billion Stargate initiative for AI data centers, crucial for maintaining a competitive edge against rivals like Google. Meanwhile, SoftBank's focus on OpenAI has slowed other Vision Fund deals, with Son personally approving transactions over $50 million. The rush to finance massive AI infrastructure, mirrored by tech giants like Meta, raises concerns about an "AI bubble" if returns fall short of expectations. Despite the risks, SoftBank's strategic moves, including potential divestitures in Didi Global, underscore its commitment to shaping the future of AI technology.
