Microsoft being late to the party is going to cost them a lot of money.

Google and Facebook are the clear leaders in AI and they been spending a lot of money building out their AI infrastructure over the last decade. You haven't heard much about Microsoft's investments other than them buying rights to OpenAI models. Seems like they could have saved a lot of money if they started investing years ago.

Google bought DeepMind for 400m 8 years ago. You could argue DeepMind is on the same level or above OpenAI.
