PHYSIX OBSERVATION

Even as the two companies go head-to-head for customers in cloud and models, their financial ties have only grown deeper, showing that Microsoft remains highly dependent on OpenAI as a revenue line in the near term. The signals worth noting are the climbing receivables and the diluted stake: the former means OpenAI's payment pressure is accumulating, while the latter suggests Microsoft's say is being gradually thinned out.
