## Takeaways

1. Ten gigawatts could cost roughly $500 billion to build.
2. SpaceX says a data-center investment could pay back in under a year.
3. The bet depends on building quickly and renting capacity at high rates.

## About this segment

John Foley says SpaceX’s 10-gigawatt data-center target could cost about $500 billion, and depends on renting capacity fast enough to recoup investment. The scale makes execution and demand central to the borrowing story.

## Transcript

Transcribed by machine (Whisper) from the episode’s audio, so a word may be off here and there.

[2:53](https://realalpha.app/v/9SAgLMahZm4/?t=173) reactions well spacex already has quite a bit of cash on its balance sheet because it did this ipo it raised debt shortly afterwards it has something like 90 billion dollars but what elon musk wants to do is build, he says, 10 gigawatts worth of data centers by the end of next year, because we measure these things in gigawatts. And a gigawatt costs very rough numbers, about $50 billion to build. So that would be $500 billion. So unsurprisingly, he needs more money with which to do that. So it's not totally surprising that he's now coming to the market and saying, can I have some more money? He absolutely needs that and much more if he's going to meet his goals of data centers on earth in space or anywhere else in the universe so 500 billion dollars i heard that correctly right that's that's how much he would need to raise in order to achieve those

[3:39](https://realalpha.app/v/9SAgLMahZm4/?t=219) goals yeah that's like taking a very rough 50 billion dollars for a gigawatt worth of data center and his plan to been build 10 gigawatts by the end of next year so i guess the question and and this seems to be reflected right now in the bond markets right now especially the credit default swaps markets, which is like, where is the money going to come from? And this is something that we had been talking about when they first went public, which is that in order to keep up with their extraordinary costs, they're going to have to raise huge amounts of money. We're already starting to see signs of it. They raised the IPO money.

[4:13](https://realalpha.app/v/9SAgLMahZm4/?t=253) then they go and issue the debt now they want to issue more debt and i guess the question is like how are they going to keep doing this i mean if they're not generating the profits do they just raise half a trillion dollars worth of debt so that's the that is the very important question is how are they going to pay for all this how are they going to how are they going to service this debt um of course they do want to make profit spacex is already making a profit from its connectivity business from Starlink. And the idea is supposed to be that because data centers are in such hot demand that you can get your investment back very quickly. So the CFO of SpaceX said quite recently that they can get payback on a data center investment in less than a year. So if that remains true, then as you're building data centers, you're also renting

[5:01](https://realalpha.app/v/9SAgLMahZm4/?t=301) them out at high enough rates that you can make your money back. Of course, the question is, can you actually build them in time? What happens to the price of data centers in the kind of rental market in the meantime? But Musk's bet is that he can do this faster than anyone else. So while everyone is scrambling to find space in data centers, he'll be able to bring his online and he'll have no problem. This is what investors are being asked to believe in renting those data centers out at very high rates to people like Anthropic, to Google, to anyone else who needs them the idea is building data centers quickly but also the idea is putting data centers in space and to me those two things seem to be completely at odds with each other you can tell i i mean you can see my prize i think that this is a little bit ridiculous but i'm just going to read you a quote

[5:46](https://realalpha.app/v/9SAgLMahZm4/?t=346) from the financial times report i don't think i'm being unfair when i say that this seems unserious uh here is exactly what was reported quote investors whom spacex has previously approached about financing its multi-billion dollar chip purchase said they only received a short two-page deal memo with pictures of outer space and an arrow pointing out that the company was going to build data centers, quote, somewhere in the universe. How are we supposed to take that to the IC, one of the people said, referring to the in-house investment committee that approves transactions. This is just an extraordinary anecdote that that is actually the pitch on a $40 billion transaction.
