Ok, maybe this question is a bit silly, but could it possibly be that Elon is doing this to steal Anthropic models secrets and using them to improve Grok?
No. Model weights are encrypted. Elon is doing this because Anthropic is desperate for compute, SpaceX needs to juice up its balance sheet before IPO, and xAI model team isn't competitive.
Love the curiosity. I recommend you spend that curiosity on figuring out why both companies are in the situation they are that this deal is a win-win: Elon has provided a masterclass in public company launch and management over the last 15 years. (And in recent years done it amidst an incredibly divisive reputational environment).
Put another way - they could maybe try to do this. But it would be worth literally nothing compared to the actual benefits to SX of this deal. And add an immense amount of risk. There’s much more clever and interesting things to do.
You won’t see “resell electricity” on the IPO brochures. They’ll say something like multi billion dollar ARR hyperscaler business.
To the extent both are true, it’s non trivial to have large grid connections in the US these days or even gas pipeline connections hooked up to generators around a datacenter. Those assets are valuable.
