Did you see that they are getting $15B/year from Anthropic because of what xAI built?

They are switching from digging for gold to selling shovels (capacity in their DCs). And it looks like they managed to make hay at the perfect time

xAI is by far their most profitable segment, receiving 1.25B a month from Anthropic.

That 1.25B per month is not profit

Assuming renting their datacenters doesn't cost them any more than running them for themselves, and plugging 15B a year of revenue (which ignores X entirely and other forms of revenue) you get 5.4B income, more than Starlink 4.4B income (which is slightly subsidized by the launch segment)

electricity is a major cost. that 1.5B/mo is part for renting the hardware, part paying the lease on the building, and a significant part (I have no idea what %) is paying for the electricity.
