SpaceX went public on June 12, 2026. Within days, the company’s valuation climbed to roughly $2.4 trillion, placing it in the same rarefied air as Apple and Microsoft. The kicker: that number isn’t just about rockets and Starlink subscriptions. It’s largely a bet on something far more speculative, putting data centers in space.

SpaceX wants to deploy a constellation of satellites that function as orbital compute nodes, powered by solar energy and connected via laser communications.

The plan behind the price tag

SpaceX laid out the blueprint in its May 2026 S-1 filing. The company’s stated goal is to launch 100 gigawatts of compute power into space on an annual basis. For context, that’s a staggering figure. The entire US electric grid has roughly 1,200 gigawatts of total generation capacity.

In January 2026, SpaceX filed with the Federal Communications Commission for permission to deploy up to one million satellites. The filing specifically targeted AI applications.

Initial demonstrations of the satellite computing capabilities could begin as early as late 2027, according to the company’s timeline.

SpaceX is already in discussions with Google about launching orbital data centers. Those conversations were revealed in May 2026.

Why space, and why now

Solar energy is abundant and uninterrupted in orbit, with no clouds, no nighttime on certain orbital configurations, and no utility bills. Cooling is paradoxically both easier and harder. The vacuum of space is an excellent insulator, which means heat doesn’t convect away naturally, but radiative cooling solutions exist. The real challenge is radiation shielding. Cosmic rays and solar particles can corrupt computations and degrade hardware, making reliability a serious engineering puzzle.

SpaceX has already deployed thousands of satellites, iterated on manufacturing at scale, and built out the laser inter-satellite link technology that would form the backbone of an orbital compute network.

Starcloud launched tests with Nvidia hardware in orbit using a Falcon 9 rocket back in November 2025, providing early proof that GPU compute can function in space. Blue Origin and Google’s Project Suncatcher represent additional entrants exploring the intersection of space infrastructure and AI computing.

What this means for investors

A $2.4 trillion valuation requires enormous future cash flows to justify. If SpaceX can deliver even a fraction of its 100-gigawatt annual target, it would create an entirely new market category.

The late 2027 demonstration timeline is aggressive. Radiation shielding, thermal management, and maintaining uptime for computing workloads in a hostile environment are unsolved problems at scale.

An FCC filing for one million satellites is unprecedented. The application will face scrutiny over orbital debris, spectrum allocation, and the sheer density of objects in low Earth orbit.
