Amazon's OpenAI Bet: Up to $50B
New details on OpenAI's massive $110 billion funding round reveal Amazon is a key backer, committing up to $50 billion in cloud infrastructure and enterprise partnerships. The deal positions AWS as the backbone for OpenAI's next offerings and solidifies its pre-IPO valuation.
Amazon's $50 billion commitment is the largest portion of a massive $110 billion funding round for OpenAI, with both SoftBank and Nvidia contributing $30 billion each. This record-breaking private financing round boosts OpenAI's pre-money valuation to $730 billion. The investment is structured in two phases: an initial payment of $15 billion, with an additional $35 billion to follow once specific, undisclosed conditions are met. This capital injection builds upon a pre-existing multi-year cloud agreement, which is now being expanded by an additional $100 billion over the next eight years. As part of the deepened partnership, OpenAI will significantly increase its use of Amazon's custom-built Trainium AI chips. The agreement specifies that OpenAI will consume approximately 2 gigawatts of power through Trainium infrastructure, spanning both the current Trainium3 and the next-generation Trainium4 chips. This deal positions AWS as the exclusive third-party cloud distribution provider for OpenAI Frontier, the company's platform for enterprise clients to build and manage AI agents. The two companies are also co-developing a "Stateful Runtime Environment" on Amazon Bedrock, designed to help customers create and scale generative AI applications. While this marks a significant partnership with Amazon, Microsoft remains a primary backer of OpenAI. Microsoft has invested over $13 billion to date and, following a 2025 restructuring, holds a 27% stake in OpenAI's for-profit arm, valued at $135 billion at the time.
