More accurately, it's impressive that Microsoft, through OpenAI, has stayed ahead of Google, AWS, and Apple while adding $1 trillion to its market cap.
I wouldn't have predicted that it would play out this way.
You're misplacing the value in this value chain. Without OpenAI Microsoft wouldn't even be in the running. It'd be a second rate cloud provider with a dying office productivity software business. OpenAI, on the other hand, would easily find another company to fund its research.
