It seems like a lot of companies are figuring out what Elon Musk has been doing so well for years: you can make a company worth whatever you want if you can sell people on a vision of how it could be worth that much.
I've heard two explanations for how Anthropic could be a good bet at its IPO price. 1. They are going to use their better-than-everyone-else AI to basically win every industry simultaneously. 2. They "get their first" and build an AI god.
If you believe 1 then you better invest in Anthropic because soon enough they will be the only company. If you believe 2 then maybe it doesn't really matter anyway?
