SpaceX Is the Neocloud With a Balance Sheet, and Anthropic's $120.5 Billion Bill Pays for Nvidia's Next Racks
Elon Musk says most neoclouds won't survive their lenders. SpaceX can rent to a tenant who's free to leave on 90 days' notice, because its lenders are counting on Starlink.
Elon Musk posted on X on Sunday that the 200-plus neoclouds (the companies that buy Nvidia GPUs and rent them out to AI labs) face "guppy-level death and consolidation." His reason was the lenders. He wrote that debt markets have mostly stopped financing companies without much revenue outside AI data centers, and he pointed to SpaceX's own GPU debt as the exception. "Some will make it through, but not many," he added. $CRWV fell 2.7% before Monday's open and $NBIS fell 3.5%.
Then on Monday Anthropic made its IPO filing public, and it shows the company agreeing to spend up to $120.5 billion on SpaceX compute through 2029. The same day SpaceX disclosed a binding $40 billion GPU financing with an Apollo-managed entity to buy Nvidia's next chips. So Elon was describing his own business when he wrote about neoclouds. $SPCX is the neocloud with the best balance sheet, and Anthropic's bill shows what that balance sheet lets it get away with.
Anthropic's $120.5 billion neocloud contract
You get the size from the monthly number. Once SpaceX delivers all the contracted capacity, which Anthropic expects in December, Anthropic pays about $3.1 billion a month. That's about $37 billion a year. In May the same relationship was $1.25 billion a month for Colossus 1 (see our earlier coverage), so the deals Anthropic signed and amended between May and October more than doubled it.
Anthropic's ceiling on its own is bigger than CoreWeave's whole order book. CoreWeave reported $103.7 billion of remaining performance obligations at the end of June (signed contract revenue it hasn't booked yet), and that's spread across every customer it has over six and a half years.
But the $120.5 billion is a ceiling. Anthropic's initial non-cancelable periods end in January and March 2027, and after that either side can walk away with 90 days' written notice. Elon said back in May that the short term was SpaceX's request. Google's contract works the same way: $920 million a month through June 2029, cancelable on 90 days' notice once 2026 ends. (Google owns its own chips and its own data centers, and it's still renting Nvidia racks from Elon.)
The neocloud balance sheet test
Elon's point holds up when you put the balance sheets next to each other. SpaceX ended September with $51.3 billion of cash and $38.6 billion of short-term securities. Its debt and finance leases came to $38.8 billion. So it holds about $51 billion more than it owes (our math from the 10-Q).
CoreWeave ended June with $5.5 billion of cash against $35.1 billion of debt. Nebius had $8.0 billion of cash and about $8.5 billion of debt, most of it convertible notes (bonds that can turn into shares), so it's roughly even.
The gap matters because of what each lender is underwriting. CoreWeave mostly borrows against its customer contracts, so a lender is looking at how long the tenant has to keep paying (our explainer on how that works). A 90-day exit clause would wreck that kind of loan. SpaceX's lenders are looking at Starlink and the launch business instead, and all three agencies rated SpaceX investment grade in June.
SpaceX is concentrated too. Its 10-Q shows one AI customer brought in 34.5% of third-quarter revenue (the filing calls it Customer B and doesn't name it). But SpaceX's debt doesn't depend on that customer staying, and a CoreWeave loan usually does.
What Anthropic's rent buys from Nvidia
Apollo's entity buys Nvidia's Vera Rubin chips and the servers around them, then leases them to SpaceX. The leases start in the first half of 2027, and SpaceX expects the deal to close by year end.
Jensen Huang told the BG2 podcast that $NVDA now sells "40 plus" billion dollars of gear for each GW of data center, because it ships the networking and CPUs along with the GPUs. At his price, $40 billion of Vera Rubin is about 1 GW of Nvidia equipment (our math). A year of Anthropic's rent at the full rate is close to that same $40 billion.
So if you follow the money, one year of the Anthropic contract pays for roughly 1 GW of Nvidia's next racks. The full $120.5 billion would cover about 3 GW at Jensen's price, though the rent also has to pay for power, buildings and SpaceX's margin, so Nvidia's share is smaller than that. (Anthropic's capacity runs on GPUs SpaceX already owns. The Vera Rubin racks are what the rent pays for next.)
You can see who carries the risk when you line up the payments. Nvidia books its part on the data center line when the racks ship, and Apollo's entity pays for them up front. Apollo then collects from SpaceX over the life of the lease, while SpaceX collects from Anthropic and Google month to month. But those tenants can leave on 90 days' notice after early 2027, and SpaceX owes Apollo for the chips either way.
Why SpaceX can carry the neocloud risk
A tenant who can leave on 90 days' notice, paying for chips the landlord still owes on, is the kind of risk Elon says lenders won't fund anymore. A neocloud with nothing but GPUs can't take that risk, because its lender won't let it. SpaceX can, because Starlink's cash sits behind the lease payments.
So SpaceX can take a contract CoreWeave couldn't borrow against. It sells short-term capacity at whatever the market pays this month, and it doesn't have to lock Anthropic into a long term to get the loan. (Elon said on the third-quarter call that he wants about half the fleet rented out at "effectively the spot market rate", so the short terms are a choice.) I'm watching March 2027, when Anthropic's last non-cancelable period ends.
After that, Anthropic's $120.5 billion is a 90-day promise. SpaceX's lenders are fine with that, and CoreWeave's wouldn't be.
