Amazon Bets $50B on OpenAI

Amazon's investment is structured in phases, starting with an initial $15 billion, with another $35 billion to follow once certain conditions are met. The full equity commitment is set to expire at the end of 2028 if the triggers for the additional investment have not been activated. This funding is deeply integrated with a massive cloud computing deal. OpenAI and AWS are expanding a previous $38 billion agreement by an additional $100 billion over the next eight years. As part of the partnership, OpenAI has committed to using 2 gigawatts of power from Amazon's custom Trainium AI chips to help meet demand. The other key investors in this historic round, Nvidia and SoftBank, are each contributing $30 billion. For SoftBank, this brings its cumulative investment in OpenAI to $64.6 billion, giving the Japanese conglomerate an ownership stake of approximately 13%. This deal represents a significant jump in OpenAI's valuation, which now stands at $840 billion post-money. For context, the company was valued at $500 billion during a secondary share sale in October 2025 and $300 billion in a funding round in March 2025. With this new funding, AWS becomes the exclusive third-party cloud distributor for OpenAI Frontier, an enterprise platform for building and deploying AI agents. The two companies will also co-develop a "Stateful Runtime Environment" on Amazon Bedrock, allowing customers to build large-scale generative AI applications. OpenAI has clarified that this new alliance does not change the terms of its existing relationship with Microsoft. Microsoft Azure remains the exclusive cloud provider for OpenAI's first-party products and APIs. The massive capital infusion is necessary to finance the physical infrastructure required to meet surging demand. OpenAI's ChatGPT now serves more than 900 million weekly active users, with over 50 million paying consumer subscribers.
