I feel like this bubble actually has two bubbles happening:
1. The infra build out bubble: this is mostly the hypescalers and Nvidia.
2. The AI company valuation bubble: this includes the hyperscalers, pure-play AI companies like OpenAI and Anthropic, and the swarm of startups that are either vaporware or just wrappers on top of the same set of APIs.
There will probably be a pop in (2), especially the random startups that got millions in VC funding just because they have a ".ai" in their domain name. This is also why the OpenAI and Anthropic are getting into the infra game by trying to own their own datacenters, that may be the only moat they have.
However, when people talk about trillions, it's mostly (1) that they are thinking of. Given the acceleration of demand that is being reported, I think (1) will not really pop, maybe just deflate a bit when (2) pops.
