OpenAI raises $110B from Amazon, Nvidia, and SoftBank at $840B valuation

OpenAI announced on February 27, 2026 that it had closed a $110 billion funding round, the largest private financing in history, at an $840 billion post-money valuation. Amazon invested $50 billion, Nvidia invested $30 billion, and SoftBank invested $30 billion, with commitments tied to cloud infrastructure and GPU compute capacity. The round came five months after OpenAI converted from its capped-profit structure amid regulatory scrutiny, and as the Trump administration accelerated AI infrastructure investment through the Stargate initiative.
