Is xAI being used by any professionals? I see them acting as a data center rental service for the others, but that doesn’t justify their valuation imo. They seem to be behind on everything and don’t seem to have any relevance. The cursor purchase may change that but for how long?

I see no reason any portion of SpaceX justifies its current valuations. I also think taking what is probably ultimately a successful and profitable company in SpaceX, even if it is maybe not as successful and profitable as Elon might say, and tying it at the hip to the AI bubble, while being clearly on the losing end of that AI bubble so far, could well kill SpaceX in the process. I hope not, because no matter how HN may feel about Elon, SpaceX has some great tech and is definitely moving space tech forward. Rather harder to say that about xAI.

But then I'd say I don't understand the valuations of a lot of companies right now. It seems to me the stock market has written into its structure the idea that United States companies will be claiming something like 500-1000% of all TAMs in the entire world in the next 10-20 years, which seems unlikely to be the case. SpaceX's claimed TAM of "pretty much the entire United States GDP, you know, why not" is merely the most blatant instance of this.

I'm not defending SpaceX or xAI. Billionaires don't need my help. But this article is still pretty pointless. Hoffman isn't a dispassionate observer, he's one of the players. Of course he's telling everyone he's going to win and the other guy is going to lose. Even when a coach is completely objectively correct when he says in his pre-game press conference that he has every confidence that his team will win in the end, it's still an information-free statement.
