Summary

SoftBank has increased its stake in OpenAI to approximately 11% following the completion of a $41 billion investment. This investment, which includes $30 billion from SoftBank's Vision Fund and $11 billion from third-party co-investors, was finalized after an initial announcement in April for up to $40 billion. SoftBank's founder, Masayoshi Son, has strategically shifted the company's focus towards artificial intelligence, aligning with OpenAI's vision for artificial general intelligence (AGI). Both companies, alongside Oracle, are also spearheading the $500 billion Stargate project, an initiative to develop AI infrastructure in the United States, announced by President Donald Trump in January 2025. Additionally, SoftBank recently acquired US data center investor DigitalBridge for about $4 billion.
