OpenAI, Anthropic, Google selling equity for the first time since their IPO, all of the downstream consumers of the frontier labs. NVIDIA is perhaps the only one profiting from actually selling something. Who hits a liquidity event before the house of cards blows over?
The original claim was "Their debt load and infrastructure costs compared to their relatively meager earnings..." which is just obviously not applicable to Google and NVIDIA, which both crank out more than $100 billion per year in profits. They can literally take on almost a trillion dollars each in debt to finance data centers and still be in reasonably good financial shape.
OpenAI and Anthropic are not very profitable (yet!), but rely mostly on equity financing, not debt. So no debt load issue there either.
