They do have their own segment that is considered neocloud (data centers for compute), but they're mostly/fully used up with their own, and Anthropic's compute.

When he was talking about neoclouds, he was talking about the smaller guys who are getting bullied by vendors (mainly Nvidia) to buy as much hardware as possible (more than they want to). They paid more, for more, and needed to take on more debt, to end up (currently anyways) being well below capacity.

Over the next few years, unless growth keeps up (and probably accelerates), they'll need to sell, or restructure.

The buildouts by Microsoft, Google, Meta, OpenAI, and Anthropic are currently safe. The neoclouds that they've signed contracts with, are safe, but based on reports, that's roughly 60% of current capacity (it varies by report, but they're all under 75%).

He specifically said that lender money dried up for neocloud companies that don't have other sources of income

SpaceX obviously has multiple sources of income, not just data center rents
