MS is not so deep with OpenAI, it's not all black and white, they have signed several distribution deals where Claude drives Copilot [1], since Anthropic and MS are better aligned in the Enterprise market, it makes sense. It also makes sense for MS not to lose ground anywhere at this point and play with the best. Actually, any cash rich company that is not OpenAI or Anthropic wants to be close-by when any of the two needs money. That's the ultimate win they can aspire for right now, get a financial slice of frontier models on one hand while not losing revenue on the other given the existential ordeal AI represents for them.
