Also keep in mind that Microsoft hasn't actually given OpenAI $13 Billion because much of that is in the form of Azure credits.
So this could end up being the cheapest acquisition for Microsoft: They get a $90 Billion company for peanuts.

I'm wondering why that option hasn't been used yet.
GPT is cool and whatnot, but for a big tech company it's just a matter of dollars and some time to replicate it. Real value is in push things forward towards what comes next after GPT. GPT3/4 itself is not a multibillion dollar business.
