No, quite the opposite. You claimed that "It's their money to invest" without knowing if it's the case or not.

No, that's not what I said. Do you have trouble with reading?

It's their money to invest however they want only if it comes with no strings attached, no obligations to use it for a specific purpose. We don't know if this is the case, so there's no basis to argue that they can do whatever they want with it.

What is corruption? It's a form of dishonesty that is undertaken by a person or an organization that is entrusted in a position of authority. That certainly seems to be the case here - not by SpaceX and xAi as such, but by Musk and his involvement in the government.

And Musk has everything to do with Grok.
