SpaceX now rents AI compute to Anthropic and Google

The company you think of as a rocket maker just reported its first earnings as a public company. The rockets are a footnote. What SpaceX actually sells now is compute, the raw AI capacity your vendors run on. And a chunk of the labs you may already depend on are renting it. Let me catch you up.

The deep cut

• Your vendor's landlord is a rocket company. SpaceX now rents compute to Anthropic and Google through its old xAI data centers.
• A failed product can become someone else's floor. xAI couldn't run Colossus, so SpaceX leased it out and tripled AI revenue.
• Founder promises are not the same as contract terms. Musk called $100 billion ARR "not a question mark" while his CFO hedged every word.

The rocket company that mostly sells compute

Look at the numbers, not the brand. SpaceX doubled revenue to $7.8 billion, and nearly $2 billion of that growth came from its AI division, which rents computing power to other labs. The space part of the business didn't clear a billion dollars and was barely a tenth of sales.

So the map changed. If you buy from an AI vendor, the physical machines behind it may sit in a SpaceX data center. That is a new dependency, and it is worth knowing about before your next vendor review.

The mistake that became infrastructure

Here is how it happened, and it is not a triumph story. Musk built the Colossus 1 data center in Memphis to train Grok. xAI couldn't run the complex well, hitting latency problems and chip bottlenecks, so they rented it out instead. The failed AI product turned into a landlord business almost by accident.

Now SpaceX has deals with Google, Anthropic, Reflection AI, and Cursor, and AI revenue tripled to $2.6 billion. But that division still lost $1.5 billion this quarter. The revenue is real. So is the fact that renting bare metal is a low-margin, capital-heavy game where compute is a commodity and everyone competes on price.

Everyone is buying from everyone in the same house

The tell is how much of this money moves between Musk's own companies. SpaceX spent $329 million on Tesla Megapacks so far this year, the batteries that smooth out the power spikes AI data centers throw off. It also owns $131 million in Tesla Cybertrucks. One man is CEO of both the buyer and the seller.

The AI demand is not fake, to be clear. AMD's data center revenue jumped 107 percent year over year to $6.7 billion on the same demand. But when your vendor's landlord, your vendor's chip supplier, and your vendor's power hardware all trace back to a tight web of related companies, concentration risk is a thing you now own too.

When the founder talks over the finance chief

Watch who says what. CFO Bret Johnsen carefully told investors the company was "on a trajectory" to hit $100 billion in ARR by December. Twenty minutes later, Musk bulldozed the hedge: "the $100 billion ARR in December is not a question mark." He also called the Starship heat shield "solved" before the test rocket was even recovered.

This gap matters for your planning. Musk claims Starlink will deliver "a majority of the world's internet" within a decade, while COO Gwynne Shotwell says "a significant portion." When a supplier's roadmap comes from the loudest promise instead of the signed contract, plan against the contract.

Three questions for your team

• Which of our AI vendors run on SpaceX compute, and do we even know? Ask the vendor directly before the next renewal.
• If a single-source landlord raised prices or cut us off, what is our fallback, and how long would a switch take?
• Are we building roadmap bets on founder promises like "$100 billion ARR" and Starlink internet, or on the numbers the CFO will actually sign for?
