Elon Musk's audacious plan to build AI data centers in orbit is quickly moving from sci-fi concept to regulatory reality. Following SpaceX's FCC filing for a million-satellite network last week and this week's formal merger with xAI, the billionaire is now publicly defending the economics of space-based computing. With FCC approval looking likely and a 2028 timeline on the table, the question isn't whether Musk is serious - it's whether the math actually works.
SpaceX just turned what seemed like an elaborate thought experiment into something much more concrete. When the company filed plans with the FCC last Friday for a million-satellite data center constellation, the tech world raised a collective eyebrow. A week later, the pieces are falling into place in a way that suggests Musk isn't joking around.
The formal merger between SpaceX and xAI went through on Monday, according to TechCrunch reporting. The move officially links Musk's rocket company with his AI venture in a marriage that makes far more sense if you're planning to launch computing infrastructure into orbit. It's the kind of vertical integration that would make even Jeff Bezos jealous.
But the real signal that this is more than Musk's usual Twitter bravado came Wednesday, when the FCC accepted the filing and FCC Chairman Brendan Carr took the unusual step of publicly endorsing it on X. Throughout his tenure, Carr has made it clear which side he's on when it comes to the Trump administration's favored entrepreneurs. As long as Musk maintains his position in the inner circle, regulatory hurdles look more like speed bumps.
The economics, though, are where things get interesting - and contentious. On a new episode of the "Cheeky Pint" podcast hosted by Stripe co-founder Patrick Collison, Musk laid out his case for why computing should migrate to space. The core argument hinges on energy costs, which represent one of the biggest operational expenses for AI data centers.
