SpaceX's $40 billion Nvidia GPU financing deal

The most consequential detail in this financing isn't the size of the check - it's who is on both sides of it. Nvidia sells SpaceX the GPUs, holds roughly 122.8 million Class A shares of SpaceX worth an estimated $17 billion to $21 billion, and is reportedly part of the lending consortium expected to help backstop the very financing SpaceX needs to buy more Nvidia chips ^[1]. Money raised from investors flows to SpaceX, which pays it to Nvidia, whose balance sheet (inflated partly by its SpaceX stake) helps make the next round of financing possible. Critics call this circularity, and it's not just an analyst talking point - across r/wallstreetbets, r/technology, and r/stocks, posts covering the deal each pulled hundreds of upvotes, and the top-voted framing on r/stocks spelled it out directly: Nvidia owns roughly $21 billion of SpaceX stock while SpaceX borrows from Wall Street to buy Nvidia's chips, with that money flowing right back toward Nvidia's own balance sheet. Prof G Markets' YouTube breakdown of the deal raised a related question: whether SpaceX's valuation holds up when the company needs tens of billions more in capital just months after closing its IPO.

A less-discussed but arguably bigger risk than circularity is the mismatch between what's backing the debt and how long the debt lasts. AI chips reportedly lose about 30% of their replacement value every year as Nvidia ships new generations, with one analysis estimating that a chip worth $1.00 in 2026 could be worth only about $0.34 by 2029 ^[1]. Yet the bond tranches reportedly being discussed for this deal can carry maturities stretching from five years out to thirty years. That means the collateral securing a meaningful slice of this debt could be worth a small fraction of its original value well before the notes backed by it even approach maturity - a structural risk that doesn't show up in headline deal size but matters enormously to anyone holding the paper.

The financing is structured as roughly $10 billion in bank loans plus $30 billion in investment-grade debt, with Apollo Global Management expected to lead the deal and place that debt with investors, and Pimco reportedly in talks to buy into the investment-grade tranche ^[2]. Apollo isn't new to this kind of trade - it has already financed two roughly $3.5 billion Nvidia-cluster deals for Musk's xAI, giving it both a template and an existing relationship to build on for a deal roughly six times the size ^[2]. The structure also goes beyond plain debt: it reportedly layers in revenue-sharing agreements tied to future AI-driven services on top of traditional loans and bonds, meaning lenders aren't just betting on SpaceX's credit - they're taking a cut of whatever AI compute business the GPUs eventually generate ^[3].

The bull case for this deal isn't purely speculative - SpaceX already has signed compute contracts that make the Nvidia GPU buildout look like a monetizable asset rather than a pure cost center. SpaceX has disclosed leasing roughly 110,000 Nvidia GPUs to Google at $920 million per month through June 2029, and about 325,000 GPUs to Anthropic at $1.25 billion per month through May 2029 ^[3]. Layer on Musk's stated targets of 2 gigawatts of AI compute online by the end of 2026, scaling to roughly 10 gigawatts by the end of 2027 ^[4], and the financing starts to look less like a bet on hypothetical future demand and more like an attempt to keep pace with contracts SpaceX has already signed.

While the deal is still preliminary, credit markets have already reacted. SpaceX's five-year credit default swap spreads - essentially the cost of insuring against a SpaceX default - jumped to a record 197.3 basis points, up from about 110 basis points when its bonds were first issued in June, and its 2056 bonds have fallen from 98.83 to 84.70 cents on the dollar ^[5]. If this $40 billion deal closes, SpaceX's total borrowing since its June IPO could reach roughly $65 billion ^[5]. The equity market's reaction has been far more muted: SpaceX stock dipped only about 1% in extended trading after the report broke, while Nvidia shares ticked up fractionally ^[2]- a sign that stock investors see this as a modest incremental risk for SpaceX and a clear demand signal for Nvidia, even as fixed-income investors are pricing in real concern.
