To be honest, it could be one with XAi too. Im no fan of Musk and Grok but the deal with Anthropic pointed out by other contributors isn't nothing. And I don't think SpaceX losing money at this stage isn't quite the problem that people think it is -- as someone who as worked at companies losing money and then going on to make quite a bit. Revenue growth is there.
The issue is that none of this is really worth $2T now. Yes, you might expect that SpaceX could launch Starship, build space-based datacenters, get a good foothold on the AI market, and grow Twitter. But you don't want to pay for future performance now, you want it to be discounted because you're taking on the risk that those things don't happen. $2T feels like expecting that story has already been actualized.
The deal with Anthropic gives me more pause about the whole market. More circular spending. They are all propping each other up making it look like they have more revenue than they really have. I think Open AIs S-1 will be just as crazy. I don't think there is any rationality or plan to all of this. AI doesn't pay for itself. It won't for a very long time.
