Completed $30B investment in OpenAI as part of record funding 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 AGI or completing an IPO by year-end), while Nvidia and SoftBank each committed $30 billion. The round remains open for additional investors. The deal includes expanded infrastructure partnerships: Amazon will provide $100 billion in additional AWS 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.
