Nvidia Capex Digest
TL;DR
The capex story's substance is still intact — Nvidia printed a fourth straight beat, TSMC raised capex, and a neocloud is raising GPU rental prices ~20% fleet-wide — but the financing layer got its first hard aggregate number: up to $300bn of Big Tech guarantees, mostly off balance sheet (nvidia-ai-capex-cycle-sustainability). Meanwhile the China leg, long written off, re-entered the picture as pure optionality: Nvidia's guidance assumes zero China data-center revenue going into a summit where Huang sat at the state dinner (nvidia-china-revenue
). Last cycle's question — who finances the next trillion — now has a documented answer, and it's a guarantee web.
The guarantee web got its aggregate number — and an IPO to test it
The financing layer's opacity problem just got a documented size and a public test case.
"Big Tech companies are rapidly expanding their use of guarantees to back debt for AI data centres and chips, issuing up to $300bn in commitments in less than a year while recording little of that exposure on their balance sheets." — FT, Sept 20, 2026
Nvidia's piece of that web is now specific: up to 25% residual value support on the Goldman-assembled $500bn platform, and a $105bn guarantee to SB Energy for the Ohio campus OpenAI will lease — booked with no balance-sheet liability until OpenAI's leases begin in 2028, in exchange for 20 years of exclusive Nvidia hardware (nvidia-infrastructure-leasing-circular-financing). The cleanest public test of what this money buys is Nscale's IPO filing: a $1.02B half-year loss on $140.6M of revenue — roughly $7 lost per $1 of revenue — with Nvidia committing $1B to its $3.1B convertible against a $103.4bn take-or-pay contract book (nvidia-infrastructure-leasing-circular-financing
). The on-balance-sheet $279B of supply commitments from the July 10-Q therefore understates total exposure; the plumbing is getting more complex faster than it's getting more transparent, which is exactly what the bond market's funding tax and the >100bps hyperscaler CDS basket are pricing.
What to watch: Nscale's IPO pricing — the thread is live, and a weak print would be the first public-market verdict on neocloud economics.
The rental market keeps voting against the depreciation bears
The strongest empirical rebuttal yet to the Burry thesis landed this stretch: a fleet-wide price increase.
"Nebius: October 1 Price Hikes Confirm Short-Term Pricing Power." — Seeking Alpha
The rate card: H100s go from $3.85 to $4.50/hr, B300s from $7.85 to $9.50 — 17–21% across the entire Nvidia fleet, effective October 1, including four-year-old H100s, while Nebius keeps adding capacity (gpu-depreciation-debate-hyperscaler-earnings). A market heading for glut does not raise rates ~20% while expanding supply; Nebius's $8.50/hr B200 sits far above the $3.00/hr bulk-Blackwell tripwire, which hasn't broken. Upstream confirms: TSMC's January–August revenue rose 39.3% YoY with 2026 capex raised to $60–64bn on "strong, sustained demand related to AI" (nvidia-ai-capex-cycle-sustainability
). Nvidia's own numbers match — TTM revenue of $302.97B (+105.9%), a fourth straight EPS beat, and $21.4B of quarterly free cash flow.
What to watch: Any hyperscaler shortening GPU useful lives or taking an impairment at upcoming earnings — that, not rental rates, is the decisive test of the $176B depreciation attack.
China went from write-off to free option on summit day
Nvidia's China leg is a story about guidance asymmetry, not current revenue.
"Not one chip. Not one dollar." — Startup Fortune, on the guidance footnote
The $108B fiscal Q3 guide assumes zero China data-center compute revenue, yet KeyBanc's John Vinh models Chinese H200 demand at ~1.5 million units a year — close to $30 billion — if licensing fully opened, and Commerce has already cleared roughly ten Chinese firms (Alibaba, Tencent, ByteDance, JD.com among them) to buy up to 75,000 H200s each (nvidia-china-revenue). The Sept 24 Trump-Xi summit put the entire US AI supply chain in one room — Huang, Altman, Nadella, Cook, Musk, Lisa Su — but Xi reportedly left Chinese CEOs home, reading as "risk management over big deals" (nvidia-china-revenue
). Since the capex story doesn't need China — direct China revenue is under 1% of data-center revenue — any thaw is upside; nothing is priced in.
What to watch: Whether a chip-policy deliverable emerges from the summit follow-through — the $30bn re-enters the conversation fast if it does, and the guidance already told you not to expect it if it doesn't.
The market's split vote is holding, through a rate hike
Equity skepticism and operating momentum coexist — and both survived the Warsh Fed's hike.
"AMD closed up about 6.4%, Micron rose 5.5%, and Nvidia gained about 2.5%." — TradingKey
AI stocks rallied through the hike with fed funds at 3.63% and a follow-up signaled, while hyperscalers haven't publicly scaled back capex plans and Nvidia hasn't lowered its demand outlook (nvidia-ai-capex-cycle-sustainability). NVDA closed at $225.51 — 4.1% off its 52-week high — at a 28.9x trailing multiple but under 17x forward, half its 2025 multiple: the de-rate documented last cycle persists, now with rate pressure absorbed on top. The split vote — sub-17x forward equity, 8-year-high CDS — is unchanged, and the concentration critique (Eisman's OpenAI/Anthropic warning) stands unresolved.
What to watch: The late-November 10-Q — the disclosure that can break out the counterparty mix of the $279B commitment stack.
What surprised us
- Nvidia is risk-managing its own web. Reuters reported Nvidia paused parts of its financing initiative for smaller AI clouds in August even as it enlarged the biggest guarantees — the company is acting like the credit analyst its bears say it should be (nvidia-infrastructure-leasing-circular-financing
).
- The $250bn OpenAI guarantee headline is a ghost. It traces to a July WSJ report; the deal that actually landed was the smaller $105bn SB Energy guarantee — treat fresh $250bn headlines as recycled until a new primary source surfaces (nvidia-infrastructure-leasing-circular-financing
- Nscale's concentration is the circular-financing debate in miniature: one customer was 52% of H1 revenue, and the bull case rests on $103.4bn of take-or-pay contracts against a business losing $7 per $1 of revenue (nvidia-infrastructure-leasing-circular-financing
- Memory rates jumped ~41% alongside GPU hikes — the input-cost squeeze on cloud margins is now moving in two directions at once.
