While headlines celebrated the world’s biggest IPO, the listing’s true significance lies not in rockets, but in AI infrastructure.

Orbital data centres would harness continuous solar energy, exploit the natural vacuum of space for thermal cooling, and utilise the existing Starlink constellation for communication.

SpaceX has become a vertically integrated monopoly spanning space transport, global broadband and AI compute infrastructure. If Musk’s orbital AI network reaches scale, global AI companies could face an insurmountable cost disadvantage.

China is not standing still. However, without reusable rockets comparable to SpaceX’s Falcon 9, the cost to orbit remains much higher, and state-owned launch schedules are saturated with national priorities. Consequently, China’s path to orbital AI depends on the maturation of its private commercial space sector.
