How much did Amazon actually invest in OpenAI?

Amazon committed up to $50 billion: $15 billion paid early in 2026 and $35 billion conditional on an OpenAI IPO or an AGI-linked "Mandatory Funding Event." If neither triggers by December 31, 2028, the $35 billion obligation expires. So the guaranteed cash was $15 billion, not the full $50 billion.

What is the stateful vs stateless loophole in the OpenAI Amazon deal?

Microsoft held exclusive cloud rights to OpenAI's "stateless" API calls (single request, single response, no memory). OpenAI argued that "stateful" agents, which keep memory and run multi-step tasks on Amazon Bedrock, were a different product category not covered by that exclusivity. Microsoft disagreed. The dispute was settled out of court when the companies amended their deal on April 27, 2026.

Did Microsoft sue OpenAI over the Amazon deal?

No. Microsoft was reported to be weighing a lawsuit in March 2026, but it never filed. On April 27, 2026, Microsoft and OpenAI instead amended their partnership: Microsoft's license became non-exclusive, OpenAI gained the right to run products on any cloud, the AGI clause was removed, and the 20% revenue share was capped through 2030.

Is OpenAI moving off Microsoft Azure?

Not entirely. OpenAI can now run its products on any cloud, including AWS, but products generally still ship first on Azure unless Microsoft chooses not to support them. OpenAI's models became generally available on Amazon Bedrock around June 1, 2026, so it now runs across multiple clouds rather than abandoning Azure.

What is OpenAI worth after this deal?

OpenAI closed its $122 billion funding round on March 31, 2026 at an $852 billion post-money valuation. Its confidential IPO filing in late May 2026 reportedly targets a valuation above $1 trillion, though the company has said it is in no hurry to list publicly.
