SpaceX's $40 billion GPU deal is four times the old record. Musk called it closed; the filing says not yet

SpaceX has lined up about $40 billion to pay for Nvidia's next-generation Vera Rubin chips, through a lease with an Apollo-managed fund. That's four times the biggest closed GPU-backed financing I can find before it. Musk said on Sunday the money was "closed." Monday's SEC filing, accepted at 8:00am ET on 26 Oct 2026 (5:00am PT; 12:00 Irish time), is more careful: it's a binding commitment, the interest rate isn't set yet, and closing is expected before year-end.

What happened

On Sunday, 25 Oct, at 3:11pm ET (12:11pm PT; 19:11 Irish time), Musk replied to investor Chamath Palihapitiya that "SpaceX closed $40B of debt for GPUs, but we're investment grade and have Starlink & launch revenue." About 40 minutes later, replying to another account, he added that it's "primarily callable debt for GPU purchases that will arrive in Q1 and Q2," and "not a major factor this quarter."

The paperwork came on Monday. SpaceX's Form 8-K was accepted by the SEC at 8:00am ET (5:00am PT), alongside a press release headlined "the largest GPU financing ever." The release itself is a little narrower: it calls the lease "the largest committed GPU financing."

What the filing actually says

According to the 8-K, SpaceX signed a binding commitment letter on Saturday, 24 Oct. Under it, an Apollo-managed entity will buy "graphics processing unit pods and related equipment" and lease them to SpaceX for data centers SpaceX picks. Here's how it works:

• It comes in tranches. Each batch of hardware gets its own lease of about five to five and a quarter years, starting when the equipment arrives.
• Rent is paid quarterly, up front. Each payment is one-twentieth of that batch's cost, plus interest at a fixed rate on the outstanding balance and some ongoing costs. Twenty quarterly payments works out to the five-year term.
• The rate isn't known yet. The filing says the fixed rate "will be determined at pricing," before SpaceX signs the actual master lease.
• The leases start in 2027. SpaceX expects them to begin in the first half of 2027 as GPUs are delivered, with total principal payments of about $40 billion.
• Who's backing it: the financing is led by Apollo and Goldman Sachs (sole structuring agent), with anchor commitments from funds and accounts managed by BlackRock and Goldman Sachs Asset Management and accounts advised by KKR, according to the SpaceX release. The 8-K itself names only Apollo.

Done deal, or not yet?

• Done: a binding commitment letter, signed 24 Oct, with named backers.
• Not done yet: the master lease itself. The 8-K says SpaceX's entry into it is "subject to certain specified closing conditions" and "expected to close prior to year end." It also lists the risk that the deal "may not close on the anticipated terms or timeline, or at all," which is standard filing language but still worth noting.
• Not in the filing: the word "callable." Musk described it that way on X. The 8-K describes a finance lease with fixed quarterly rent and doesn't mention early buyout terms either way.

To be fair to Musk, a finance lease shows up on the balance sheet much like a loan, so calling it "debt" is reasonable. And a binding commitment from Apollo, BlackRock and KKR is a lot more than a handshake. But "closed" isn't the word the lawyers used. Reuters put "closed" in quote marks too, and on Sunday it said it wasn't clear whether investors had agreed on pricing.

How big is $40 billion?

Here are the biggest GPU-backed financings I could check, using the companies' own announcements:

Sizes are headline amounts as announced. CoreWeave's 2026 facility starts at about $7.5 billion and can grow to $8.5 billion. The Apollo deal backed a $5.4 billion Valor purchase and lease of GPUs to xAI. Ratios are my own math.

The "old record" is Firmus. The independent tracker American Compute ranks it first among closed GPU-backed financings, and as of its 10 Oct 2026 update, the 25 largest add up to $65.3 billion. SpaceX's one deal is about 61% of that whole list. The tracker covers public deals only, so treat it as a floor. It also lists bigger data-center deals secured on buildings rather than chips, such as Meta's $27.3 billion Hyperion bonds, which aren't GPU financings.

One more comparison. Apollo said in January that its funds had "deployed over $40 billion" into next-generation infrastructure since 2022. This one lease is about the same size. And that January deal was already a lease of GPUs to xAI, which is now part of SpaceX. So Apollo has been here before, at less than a tenth of the scale.

What it means for SpaceX's spending

SpaceX spent $19.59 billion on capex in Q3, and $16.44 billion of it went to the AI (SI) segment. CFO Bret Johnsen still expects $35 billion to $40 billion in Q4, per Reuters. So the lease is roughly a quarter's worth of spending at the new pace, or two quarters at the Q3 rate. But Musk's own reply is the key detail: this money pays for chips arriving in 2027. It doesn't fund this quarter's bill.

It's also about three times SpaceX's existing leased-GPU borrowing. The Q3 10-Q showed $12.9 billion of debt for leased AI hardware owed to Valor, the firm run by SpaceX director Antonio Gracias. The new lease is about 3.1 times that. It's also with an outside lessor, which matches the CFO's line that it "diversifies our funding sources."

What could it cost? (My math, not SpaceX's.) If all $40 billion were outstanding at once, principal alone would come to about $2 billion a quarter, or $8 billion a year, because each quarterly payment is a twentieth of the cost. Interest comes on top. Every percentage point on the still-unset rate would add about $400 million a year at the full balance, falling as the leases pay down. In practice the tranches will start at different times as chips arrive, so the real payments will be spread out more than that.

Why Vera Rubin, and why now

Vera Rubin is Nvidia's successor to Grace Blackwell. Nvidia said on 31 May that it was ramping into full production, with production shipments starting this fall, and claimed "10x agent throughput" over Grace Blackwell. That's Nvidia's number, not an independent test. SpaceXAI was on Nvidia's list of cloud providers adopting its Confidential Computing on the platform.

The timing is Musk's point. He says debt markets have "almost entirely shut off" for companies without substantial revenue outside AI data centers, and that "200+ neoclouds" face "guppy-level death and consolidation." That's his opinion, not a market statistic. But SpaceX can point to Starlink, which made $2.37 billion in operating income in Q3. Most of the neoclouds he's talking about can't. The CFO's claim of "less than one year payback periods" on its AI infrastructure is also SpaceX's own figure. The filing doesn't break it down.

What to watch

• Pricing. The fixed rate gets set before the master lease is signed, and it's the number that decides what this costs.
• Closing. SpaceX expects it before 31 Dec. A follow-up filing should confirm it.
• Deliveries. Leases only start when Vera Rubin pods arrive in the first half of 2027. Slips at Nvidia or the server makers would push everything back.

Bottom line: SpaceX has a binding, Wall Street-backed commitment for about $40 billion of Vera Rubin hardware, four times the largest closed GPU-backed financing before it. It isn't closed yet, and the rate isn't set. If it closes on time, SpaceX will be paying for its 2027 compute over roughly the next five years, with Starlink as the backstop.
