Microsoft has solidified its 27% stake in OpenAI, valued at around $135 billion, under a long-term partnership extending to 2032. The deal secures Microsoft’s access to OpenAI’s AI and AGI models and includes OpenAI’s $250 billion commitment to Azure cloud services. New developments reveal Microsoft will also receive 20% of OpenAI’s revenue as part of the company’s profitable transformation. While Microsoft maintains API exclusivity for some products, OpenAI can host non-API offerings on other cloud providers, reflecting increased deployment flexibility.
