Do you think token demand is going to drop after the collapse? I seriously doubt it.
IMO the collapse will come because the insane profits that OpenAI/Anthropic valuations depend on will collapse due to margin collapse from competition from Open Weight / Chinese models.
IOW, a reduction in price of tokens. Which will increase demands for tokens, and the electricity needed to generate them.
This might result in bankruptcy of some of the holding companies holding data center debt, but with that debt discharged in bankruptcy the data centers will be quite profitable and keep operating.
Training demand will also collapse after a crash, but training is now a minority of data center demand.
IOW, those electric bills are going to continue to get paid. I wouldn't want to hold OpenAI/Anthropic stock or data center debt though.
