Nvidia Capex Digest — Is the AI Capex Story Still Intact?
TL;DR
The story is intact where Nvidia sits and strained everywhere else: NVDA printed a fresh $5.78T close on the back of a brand-new, entirely debt-funded buyer class, while the WSJ reported three simultaneous mega-deals that make private credit the buildout's "central financial backstop." Last cycle's digest framed the fault line as collateral quality; this cycle it's clearer still — the seller is clean, the guarantor is discounted, and the marginal Nvidia customer is now a leveraged entity.
Private credit just became the buildout's balance sheet
The financing layer crossed from exception to organizing principle. The Wall Street Journal reports Broadcom, Oracle and SpaceX are each in talks for private debt deals worth "tens of billions of dollars each to purchase AI hardware," and that the rush signals "traditional public bond markets and internal corporate cash flows are approaching their limits under the immense financial strain of global data-center expansion" (WSJ via Investing.com). The three structures are distinct bets: Broadcom assembling >$50B (with Apollo and Blackstone) to finance custom chips for OpenAI under its internal "Nexus" program; Oracle using Apollo and Goldman to fund a 1-gigawatt SPV that buys chips and leases them back off-balance-sheet; and SpaceX seeking ~$40B — $10B in bank loans plus $30B in investment-grade debt — Apollo-led, Pimco in talks, closing expected 2027 (24/7 Wall St.).
The issuance wave underneath is the context that makes these deals legible: Goldman pegs low-rated AI-related debt at $88B in 2026, BNP Paribas counts $40B of AI high-yield supply versus $12B in all of 2025, and Morgan Stanley projects AI infrastructure will need $1.5 trillion of outside financing by 2028 (off-balance-sheet-ai-infrastructure-financing-models+1). This extends last cycle's read — where Volta's 11% print and the $60B Broadcom–Anthropic syndication were the marginal signals, now the marginal deal itself is off-balance-sheet or vendor-financed. The buildout's critics predicted exactly this architecture; the bulls' defense is that the seller's own balance sheet stays pristine.
What to watch: Volta's clearing yield at the Oct 14 commitment deadline — still the next hard datum for what unrated GPU-collateral paper actually costs.
The market is now pricing the seller/guarantor split directly
The equity market has started discounting the credit role in real time. Broadcom — simultaneously Anthropic's supplier, lessor, lender and guarantor, with the prospectus itself flagging the arrangement as a "potential conflict of interest" — carries $102B of exposure where it's guarantor, direct lender, or both, "roughly equal to Broadcom's entire fiscal 2026 revenue" (off-balance-sheet-ai-infrastructure-financing-models+1). Its CDS hit a record 122 basis points in August, and the equity has noticed: AVGO closed at $376.51, 21.5% below its 52-week high, while NVDA — the party that gets "paid when the chips ship" — sits at 97.6% of its high. Same boom, opposite ends of the range.
The SpaceX order shows why the asymmetry holds. Musk, on the Aug 4 call:
"So we're exclusive to NVIDIA." — 24/7 Wall St.
But look at the borrower: Q2 revenue of $7.81B against $18.37B of capex — $15.83B of it AI — and a $541M net loss, with management guiding the next two quarters "very similar." The order is roughly five times quarterly revenue, funded entirely in debt. 24/7 Wall St. names the coupling plainly: "NVIDIA's revenue stability depends in part on whether those buyers can carry their debt." That's the quiet change from last cycle — NVDA's own balance sheet (0.2x debt/EBITDA) is untouched, but the quality of its order book is now a credit question.
What to watch: whether Broadcom's Nexus package for OpenAI confirms — vendor-financing the leading custom-silicon alternative to Nvidia would put the guarantor discount and the competitive threat on the same balance sheet.
The equity layer keeps voting "intact"
The stock absorbed the SpaceX news and kept climbing: a record intraday $243.37, a $5.78T close, RSI 77, and a breakout past IBD's 234.76 cup-with-handle entry (nvidia-record-q1-results-and-trillion-dollar-order-book+1). The fundamentals under it haven't degraded — TTM revenue $302.97B (+105.9% YoY), 74.7% gross margin, four straight beats. Even a $40B order is under 1% of market cap; the demand story no longer needs any single customer to work.
What to watch: Q3 FY2027 earnings Nov 17, guided to $108B revenue at ~74% gross margin — the next checkpoint that the demand base is growing into everyone else's leverage.
What surprised us
- SpaceX is a fourth customer class, and it's the most leveraged one yet. Hyperscalers, sovereigns, neoclouds — and now a loss-making space company pledging exclusivity while borrowing five times its quarterly revenue. The order book keeps extending, but each new tier carries less of its own capital.
- Broadcom is financing the competition to the very chips it guarantees debt against. A >$50B package to fund OpenAI's custom silicon, layered on $102B of Anthropic exposure — the guarantor role and the Nvidia-alternative role are now the same balance sheet, which may be why the market discounts it.
- The Oracle SPV template went from one-off to playbook. Amazon's $8B Grace Blackwell SPV was a curiosity last cycle; a whole-gigawatt leaseback for Oracle suggests off-balance-sheet chip SPVs are becoming standard hyperscaler plumbing.
- SpaceX insiders got their sell window exactly as the debt was marketed — 328.4M shares unlock Oct 9, another Oct 24, up to 1.3B after Q3 earnings, with the stock at $171.92 off a $135 IPO and a $225.64 peak.
Open threads worth a vote
