Musk’s AI Startup Is a Payload SpaceX Can’t Afford

SpaceX has a big head start on the technology of reusable rockets, which drastically lowered launch costs and helped spawn a commercial space industry that is gaining momentum year by year.

As SpaceX prepares for its huge Starship rocket to enter commercial service, nothing could derail the company from its leadership position — except perhaps a truly bad decision to chain a financial anchor around SpaceX’s neck. That looks to be the case with Elon Musk’s surprise move to tuck xAI, his cash-gulping AI startup, under SpaceX.

The combination has an eye-popping value of $1.25 trillion, with SpaceX accounting for $1 trillion of that, according to a Bloomberg News report.

Ignore any talk of xAI synergies with SpaceX. They don’t exist right now. SpaceX has been doing just fine at revolutionizing the space industry all by itself — first with its Falcon 9 workhorse rocket. It enabled Musk to build the Starlink constellation of low-Earth-orbit satellites that provides mobile broadband internet for ships, planes, recreation vehicles, rural homes and battlefields in Ukraine.

It’s astounding that SpaceX has progressed so quickly from its first successful rocket flight in 2008 — after three failed attempts — to 165 missions last year, which was more than half of the global launches. Let’s be clear, SpaceX is why the US is dominating the space race with China, which is urgently developing its own reusable rockets and building a low-Earth-orbit satellite network.

SpaceX makes money charging customers by the ton to carry their payloads into space, but most of its launches last year added to its Starlink network of 9,000 satellites, which is the main reason SpaceX is profitable. Customers, including United Airlines Holdings Inc. and ocean carrier AP Moller-Maersk A/S, are flocking to Starlink because of its global coverage and much faster speeds than internet service from the traditional geosynchronous satellites that are positioned much farther from Earth.

SpaceX, which produces its own satellites, also makes money on government contracts, mainly from NASA and the Defense Department, and will likely play a key role in building out the space-based missile-defense system called Golden Dome. The reliability and lower cost of launches have made the government more dependent on SpaceX than the other way around.
