What's really interesting is that OpenAI has been maneuvered into a really bad strategic position. Theoretically, they could jump into the arms of any other FAANG and get the compute and funding they need. However, Microsoft remains a 49% equity holder so they don't have much to offer to this new corporate savior. Microsoft effectively licked the OpenAI cookie once they bought such a large stake in the company.
The only strategic play left to OpenAI is spite. They can choose to burn down Chat GPT which will lead to a scattering of their talent across competitors (although Microsoft will likely just pick up most). This will slow down Microsoft by a couple of months but will be nothing more than a bump on their way to AI dominance.
