The problem is that all the AI companies have been getting incredibly intertwined, see [0] for example. Nvidia isn't
just selling chips - it is also actively investing in its own customers in order to drive up demand. This is giving us neat headlines like "NVIDIA intends to invest up to $100 billion in OpenAI as the new NVIDIA systems are deployed". The Coreweave deal is even worse: Nvidia is investing in Coreweave, so that Coreweave can buy GPUs from Nvidia, so that Nvidia can rent compute from Coreweave.
Sure, Nvidia is making crazy money right now, but what's going to happen to all those deals when the market blinks and some of those lesser players start falling over?
