SpaceX 5GW outlook... power calculation for 10,000 units of equipment is up to 4GW

GF Securities director Jeff Pu forecast in a November 10 X post that SpaceX will hold roughly 5GW of space-based AI compute capacity by 2028 using about 10,000 Kessel units, though the stated unit count multiplied by maximum per-unit power draw arithmetically yields only up to 4GW, short of the headline figure. Kessel is a space-grade compute unit carrying 72 of Nvidia's ($NVDA) Rubin GPUs, and Pu timed supply-chain volume ramp-up for the second half of 2027 through 2028. The forecast is Pu's estimate rather than SpaceX's official deployment record. The gap between the 5GW projection and the 4GW implied by the hardware math is the key discrepancy to watch, along with whether SpaceX confirms Kessel volumes and per-unit power specs as the 2027-2028 buildout window approaches.
