Delivered second $10B tranche from $40B loan, completing $40B total OpenAI commitment in $122B round

In October 2024, OpenAI raised $6.6 billion at a $157 billion valuation. Seventeen months later, on February 27, 2026, the maker of ChatGPT closed a record $110 billion funding round at a $730 billion pre-money valuation ($840 billion post-money)—the largest private capital raise in history. Amazon led with a $50 billion commitment ($15 billion upfront, $35 billion contingent on OpenAI achieving artificial general intelligence or completing an initial public offering by year-end), while Nvidia and SoftBank each committed $30 billion. On April 1, 2026, SoftBank delivered a second $10 billion tranche, expanding the total round to $122 billion at an $852 billion post-money valuation with participation from Andreessen Horowitz and D.E. Shaw Ventures. The deal includes expanded infrastructure partnerships: Amazon will provide $100 billion in additional Amazon Web Services compute services over eight years (on top of the existing $38 billion commitment), while Nvidia will supply 3 gigawatts of dedicated inference capacity and 2 gigawatts of training capacity using its Vera Rubin systems.

Leading SoftBank's pivot to AI infrastructure ownership while racing to meet $22.5B year-end Stargate funding deadline

SoftBank just agreed to pay $4 billion for DigitalBridge, the alternative asset manager that controls $108 billion in data centers, cell towers, and fiber networks across three continents. It's the latest—and clearest—signal that Masayoshi Son is betting SoftBank's future on owning the physical infrastructure that powers AI, not just the software running on top of it. The timing is no coincidence: SoftBank is racing to secure $22.5 billion by year-end 2025 to meet its Stargate funding commitment to OpenAI.
