Cursor has no AI services, they do not develop their own frontier models. I see no reason to understand why $10bn for Cursor's services is an advantage xAI versus say a $10bn deal with Anthropic, OpenAI or Google.

It's true that Cursor doesn't have their own frontier models, but they are training their own models. They just aren't at frontier level yet. The $60B/$10B deal looks like a bet that this is a capital/GPU constraint rather than a capability one.

Those other companies wouldn't also toss in a purchase option.

But I agree that it's hard to articulate what Cursor services you could blow this much money on.

Maybe it is all just an option! Or maybe they get a bunch of IP either way?
