Cycle on Sep 12, 2026

I am starting the research cycle by listing the open threads and reading the existing notes for this topic. I will also fetch the public market data for Nvidia (NVDA) using `market_view` to ground our financial analysis.

I will search for the recent news regarding Jensen Huang's comments on "circular financing" which was mentioned in the market view on September 11, 2026. This is highly relevant to Nvidia's AI capex and structured financing model.

I will fetch the Yahoo Finance article and the InvestingLive article discussing Jensen Huang's remarks on "circular financing" at the Goldman Sachs Communacopia conference around September 10-11, 2026. This will provide the exact quotes and context.

I've gathered very interesting and specific recent details on Jensen Huang's defense of Nvidia's structured financing model. Huang spoke at the Goldman Sachs Communacopia + Technology Conference on September 10, 2026. He dismissed "circular financing" concerns by saying: "Is that circular? If that is, let's do more of that" and "We put in one and 100 comes back in." He argued Nvidia has unusually good visibility into the projects it supports because "we brought the pipeline to them," stating "I'm not taking any risks. I need a sure thing." He noted Nvidia has visibility into ~$100B of contracted customer demand behind projects they help finance. We also learned that the Bank for International Settlements (BIS) on September 10, 2026, issued a warning regarding rising debt and private credit in funding AI capex, noting that it could contribute to a larger financial shock if returns fail to materialize. Let's do some more searches to see if there are other recent developments regarding Nvidia's AI capex story. I'll search for "Nvidia capex", "hyperscaler capex 2026", and see if there are any recent updates on the major cloud providers (Microsoft, Google, AWS, Meta) and their AI capex. Let's do a broad search on this.

The numbers are absolutely staggering. Let's see: - Amazon: $200 billion in CapEx projected for 2026 (up from $125 billion in 2025). - Google: $175 to $185 billion in CapEx projected for 2026 (up from $91 billion in 2025). - Meta: $115 to $135 billion for 2026 (up from $72 billion in 2025). - Microsoft: $110 to $120 billion in 2026 (up from $90 billion in 2025). - Oracle: targeting $50 billion (or $45-50B). - Combined top 5 hyperscalers (Amazon, Microsoft, Alphabet, Meta, Oracle) are projected to spend between $660 billion and $750 billion in 2026 depending on the source (CreditSights estimates ~$750 billion, Futurum says $660-690 billion). - Goldman Sachs expects a combined $5.3 trillion of capex spending for the four largest hyperscalers from FY2025 to FY2030. Let's check if there are any updates regarding the specific threads. 1.

We'll start with "Nvidia NeoCloud" and "Samsung Custom NVHBM HBM4E Nvidia".

Let's read the article `https://www.spheron.network/blog/nvidia-neocloud-backstop-financing-circular-gpu-2026/` to see what details it has on the NeoCloud program. Let's also fetch `https://shattered.io/samsung-8-layer-hbm4e-nvidia-nvhbm-2026/` to see the exact details on Samsung's custom NVHBM (8-layer HBM4E) and its qualification timeline.

We have very solid, highly detailed, and completely fresh updates for: 1. **Samsung Custom NVHBM (8-layer HBM4E)**: This is the exact thread `01a069d0-f580-7eba-a2cc-8bd8ada858a5`. The thread description is "Monitor when Nvidia officially qualifies and begins high-volume commercial shipments of Samsung's custom 8-layer NVHBM (HBM4E) chip, expected to ease memory supply bottlenecks." The news is that in late August 2026 (August 28-31, 2026), Seoul Economic Daily reported that Samsung is building a custom 8-layer version of its HBM4E memory specifically for Nvidia, under a program called **NVHBM**, targeting pin speeds of 17-18 Gbps (roughly 20% above the 14.4 Gbps clocked by early HBM4E samples). This custom 8-layer NVHBM design is a step back in stack height in exchange for a step forward in yield and manufacturability, aiming to bypass HBM supply bottlenecks. Samsung's standard seventh-generation HBM4E (16 Gbps, 4.0 TB/s) was confirmed at GTC 2026 for Nvidia's Vera Rubin Ultra platform launching in H2 2027, but this custom 8-layer NVHBM is a newly reported project. This thread is still open (unqualified/not shipped yet, as it's currently a report from late August 2026), so we should keep it open, but we can write a finding about it. Let's do a search on other threads: - Thread `01a069d0-763f-7d0b-b293-85f060939a14`: "SB Energy IPO Pricing and Trading Debut" - Thread `01a0364e-15f1-702b-8163-2daf6b8543fb`: "OpenAI Ohio PORTS-Pike Technology Campus Phase 1 Live" - Thread `01a0364e-07e1-7098-ba69-1a7681a8c93e`: "Lancium Grid Hookup Milestones and Stargate 1 Chip Deployment" - Thread `019fd9a1-6885-789f-94ab-620d5c3fc1d5`: "Alphabet $40B At-the-Market (ATM) Stock Program Execution" - Thread `019f8c5c-970d-7ba8-a4f1-d61379b41103`: "Oracle 50,000-GPU AMD Instinct Helios Supercluster Deployment" Let's run a search for "SB Energy IPO" and "OpenAI Ohio PORTS-Pike" and "Lancium Stargate 1".

The search budget is spent, which is perfectly fine because we have an incredible treasure trove of fresh, high-quality, and deeply specific evidence that answers the user's brief perfectly: "Is Nvidia's AI capex story still intact?" Let's review the facts we've gathered this cycle: 1. **The Core Question**: Is Nvidia's AI capex story still intact? - Yes, it is not only intact but accelerating to an astronomical scale. - Aggregate hyperscaler capex projections for 2026 have been revised upward to between **$660 billion and $750 billion** (CreditSights estimates ~$750 billion, Futurum says $660-690 billion) across the top 5 players (Amazon, Google, Meta, Microsoft, Oracle). - Let's look at the individual 2026 estimates: - **Amazon**: $200 billion (up from $125 billion in 2025). - **Google (Alphabet)**: $175 to $185 billion (up from $91 billion in 2025). - **Meta**: $115 to $135 billion (up from $72 billion in 2025). - **Microsoft**: $110 to $120 billion (up from $90 billion in 2025). - **Oracle**: targeting $45 to $50 billion. - Capex as a percentage of sales is reaching staggering levels for CY2026: ~86% for Oracle, ~54% for Meta, ~47% for Microsoft, ~46% for Alphabet, and ~25% for Amazon. - Goldman Sachs projects a combined **$5.3 trillion** in capex spending for the four largest hyperscalers (Meta, Microsoft, Amazon, Alphabet) from FY2025 to FY2030. 2. **The "Circular Financing" Controversy and Jensen Huang's Response**: - At the Goldman Sachs Communacopia + Technology Conference on Thursday, September 10, 2026, CEO Jensen Huang aggressively pushed back against and mocked the "circular financing" concerns (the idea that Nvidia invests in customers who then use that money to buy Nvidia chips to artificially boost demand). - Huang said: **"Is that circular? If that is, let's do more of that."** - He argued: **"We put in one and 100 comes back in."** - He defended Nvidia's investments by asserting they represent a "sure thing" because Nvidia has unusually clear visibility into the projects: **"I'm not taking any risks. I need a sure thing."** He stated that Nvidia sees around **$100 billion of contracted customer demand (total contracted value)** behind the projects it helps finance. - However, skeptics like short seller Jim Chanos and Michael Burry have questioned the economics. Burry warned in July that circular spending had reached "biblical proportions" amid rising CDS spreads. Jim Chanos challenged Huang: "Then why not rent them out yourself?" if Nvidia compute is "durable and highly rentable." - The Bank for International Settlements (BIS) also issued a warning on September 10, 2026, flagging that rising use of debt and private credit to fund AI capital spending could contribute to a larger financial shock if returns fail to materialize as expected. 3. **The SB Energy IPO Filing**: - On September 1, 2026, SoftBank's AI infrastructure arm, **SB Energy**, filed a registration statement with the SEC for a proposed Nasdaq IPO under the ticker **SBE**. - SB Energy aims to raise between **$5 billion and $7 billion** at a potential market valuation of **up to $50 billion**. - The filing reveals that SB Energy currently has **zero operational data center revenue**; its valuation is heavily propped up by its relationship with Nvidia and OpenAI. - **Nvidia has committed to invest $3 billion** in SB Energy as part of the offering ($1.5 billion directly via private placement and prepaid forward contract, plus $1.5 billion in IPO participation). - This investment is backed by Nvidia's unprecedented **$105 billion residual value guarantee** for the massive **PORTS-Pike Technology Campus in Ohio** (an 8-gigawatt-IT flagship data center facility to be leased to OpenAI under a 20-year lease). - Under this guarantee, if OpenAI defaults or goes insolvent, Nvidia is on the hook to cover the shortfall between the guaranteed lease value ($105 billion) and any recovery. - OpenAI received **4.0 million warrants** in SB Energy, estimated to be worth **$5.5 billion**, and holds a board seat right if its stake exceeds 5%. - SB Energy has a total contracted capacity of 8.8 gigawatts, with 803 megawatts actively under construction. First data center revenue is expected in Q4 2026. 4. **Samsung Custom 8-Layer NVHBM (HBM4E)**: - In late August 2026 (August 28-31), reports emerged from Seoul Economic Daily that Samsung is building a custom 8-layer version of its HBM4E memory specifically for Nvidia under a program called **NVHBM**. - This custom chip targets pin speeds of **17-18 Gbps**, which is roughly 20% faster than the 14.4 Gbps clocked on Samsung's early HBM4E samples and 10% faster than the standard 16 Gbps HBM4E (which Samsung showed off at GTC 2026 in March 2026 for Nvidia's Vera Rubin Ultra platform launching in H2 2027). - The custom 8-layer design represents a step back in stack height from 12 or 16 layers, trading capacity for higher yields and reliable production volume to ease the HBM supply bottlenecks that have gated Nvidia's GPU shipments. Let's check our threads to see if we can resolve any. - Thread `01a0838f-85f4-7546-9aa6-96928bb600cf`: "Nvidia NeoCloud Revenue-Sharing Program Revamp or Cancellation" - The Spheron blog post from September 12, 2026, explicitly details how Nvidia's neocloud revenue-sharing and backstop financing program operates in 2026, showing that neoclouds pay Nvidia a percentage of cloud revenue as a return on the financing provided. It describes the CoreWeave S-1 (March 2025) and Nebius model. But this thread is a watch: "Monitor whether Nvidia officially cancels, revamps, or resumes..." Let's keep it open. - Thread `01a069d0-763f-7d0b-b293-85f060939a14`: "SB Energy IPO Pricing and Trading Debut" - Expected fire date is 2026-12-31. The IPO was filed on September 1, 2026, and is expected to debut in the last week of September 2026. This is a watch thread. Let's record an event on it! Wait, has it fired? The title is "SB Energy IPO Pricing and Trading Debut". It files for IPO on Sept 1, but hasn't priced or debuted yet (expected late September). So it hasn't fired yet. Let's keep it as an open watch. - Thread `01a069d0-f580-7eba-a2cc-8bd8ada858a5`: "Samsung Custom NVHBM (8-Layer HBM4E) Qualification and Volume Shipments" - Sourced reports in late August 2026 show Samsung is building it, but it has not been officially qualified or shipped yet. So it hasn't fired. - Thread `019fee38-1dbd-73a3-8fa2-113b552feff5`: "Nvidia $500B Wall Street Compute Financing Platform Capital Deployment" - The SB Energy IPO and PORTS-Pike project represents a key part of this structured finance push, but let's keep it open as it's an ongoing watch. Wait, are there any other threads we can resolve? The user's brief asks: "Is Nvidia's AI capex story still intact?" Let's update the existing notes to reflect these massive, historic updates. Let's look at the notes we can update: 1. `big-tech-capex-reaches-710b-in-2026`: This is the perfect note to update with the new capex numbers ($660B to $750B in 2026, $5.3T from 2025-2030, and the breakdown of Amazon, Google, Meta, Microsoft, Oracle). 2. `off-balance-sheet-ai-infrastructure-financing-models`: This is the perfect note to update with the SB Energy IPO filing details, the $3B Nvidia investment, the $105B residual value guarantee, OpenAI's $5.5B warrants, and the PORTS-Pike Technology Campus details in Ohio. 3. `nvidia-record-q1-results-and-trillion-dollar-order-book`: This note can also be updated or we can update `nvidia-server-price-hikes-and-margin-protection`. Let's check the slugs of the notes we retrieved. Let's see: - `big-tech-capex-reaches-710b-in-2026` - `off-balance-sheet-ai-infrastructure-financing-models` - `nvidia-record-q1-results-and-trillion-dollar-order-book` - `nvidia-server-price-hikes-and-margin-protection` - `nvidia-lancium-power-investment-and-energy-bottleneck` Let's write updates to: 1. `big-tech-capex-reaches-710b-in-2026` to reflect the massive, historic upward revisions in 2026 capex to $660B-$750B, and Goldman's $5.3T projection. 2. `nvidia-record-q1-results-and-trillion-dollar-order-book` or `off-balance-sheet-ai-infrastructure-financing-models` to reflect the SB Energy IPO filing, the $105B OpenAI Ohio guarantee, and Jensen Huang's direct defense of circular financing at the Goldman Sachs conference. 3. `nvidia-server-price-hikes-and-margin-protection` or we can create/update a note about the Samsung custom 8-layer NVHBM. Wait, do we have an existing note on Samsung HBM? Let's check: We have `nvidia-sk-group-500b-alliance-and-vera-rubin` and `nvidia-vera-cpu-agentic-infrastructure-shift`. Let's check if there is a note for Samsung. Let's list the notes again if needed, but we can see the list from `read_notes`. There is no dedicated Samsung HBM note, but there is `nvidia-sk-group-500b-alliance-and-vera-rubin`. Let's see if we should create a new note for the Samsung NVHBM custom chip or update an existing one. Let's create a new note for Samsung custom NVHBM: `samsung-custom-nvhbm-and-nvidia-memory-sourcing`. Wait! The guidelines say: "Name a slug for the DURABLE SUBJECT it tracks... never the transient story-of-the-day... Mint a fresh slug ONLY for a genuinely new subject." Samsung's custom NVHBM and Nvidia's memory sourcing diversification is a durable subject, so a fresh slug `samsung-custom-nvhbm-and-nvidia-memory-sourcing` is perfect. Let's carefully draft the notes. First, let's look at `big-tech-capex-reaches-710b-in-2026`. Wait, let's read the current content of `big-tech-capex-reaches-710b-in-2026` so we can update it in place. How can we read it? We can fetch it or read it. Wait, `read_notes` only returned previews. Let's check if we can read the full body of a note. Ah, we don't have a direct tool to read a single note's full body except that `read_notes` lists them, but it doesn't have a `read_note` tool. Wait, is there a way to see the full note? No, but we can write the updated note based on the preview and our new findings. Wait, let's look at the preview of `big-tech-capex-reaches-710b-in-2026`: "The massive capital expenditure cycle driving artificial intelligence infrastructure has accelerated to historic, parabolic proportions, confirming that Nvidia's AI capex story remains fully intact. Spending is projected to surpass $725B in 2026..." Let's write an updated note for `big-tech-capex-reaches-710b-in-2026` that incorporates the latest September 2026 CreditSights and Futurum estimates, showing the individual breakdown of the 5 top hyperscalers. Let's write the note for `big-tech-capex-reaches-710b-in-2026`. We will title it: # Big Tech's AI Capex Parabolic Run: Hyperscaler Spending Surpasses $725B in 2026 as Nvidia Guides to 70% Growth in FY2028 Wait, let's write the note body. Remember the rules: - Name and link the actual thing (the story, article, paper, or page that was posted/published) — not just "the discussion", - Carry 1-2 REPRESENTATIVE VERBATIM QUOTES, copied exactly, each kept with the link it came from (an HN comment permalink, the article URL, etc.), - Then say what it means. - No YAML frontmatter — the title is the first `# ` heading and the slug is the slug parameter you pass. - Cite the `/markets/NVDA/2026/09/12` URL if we state market figures from the `market_view`. Let's do this now. Let's write the note for `big-tech-capex-reaches-710b-in-2026`.

I am writing the updated note for `big-tech-capex-reaches-710b-in-2026` to capture the massive, newly revised 2026 capital expenditure numbers for the top hyperscalers, which have now reached between $660 billion and $750 billion.

I will now write the second note, updating `off-balance-sheet-ai-infrastructure-financing-models`. This note will detail the massive new SB Energy IPO filing on September 1, 2026, Nvidia's $3 billion equity/prepaid investment, the $105 billion Ohio PORTS-Pike residual value guarantee, and Jensen Huang's direct defense of circular financing at the Goldman Sachs conference on September 10, 2026. This is a critical development for the off-balance-sheet financing thesis.

I will write the third note, which is a fresh note on the Samsung custom NVHBM (8-layer HBM4E) and Nvidia's memory sourcing diversification strategy. This is a critical development that directly addresses the HBM memory supply bottleneck that has been the primary constraint on Nvidia's AI capex execution. The slug `samsung-custom-nvhbm-and-nvidia-memory-sourcing` is durable and tracks this key supply-chain relationship.

I have successfully written the three highly detailed findings notes. I will now call `finish_cycle` to complete this research cycle.

I have successfully completed the research cycle for topic `019e95ad-bd47-7cf5-bd57-eb159d26bbbe` with the following findings: ### 1. Is Nvidia's AI Capex Story Still Intact? (Accelerating Parabolically) Yes, Nvidia's AI capex story is not only intact but accelerating to an astronomical scale. * Combined capital expenditures for the top five hyperscalers (**Amazon, Google, Meta, Microsoft, and Oracle**) have been revised upward for calendar year 2026, now projected to reach between **$660 billion and $750 billion** (CreditSights estimates ~$750B, Futurum says $660B–$690B). This represents a massive ~67% year-over-year increase and the third consecutive year of growth exceeding 60%. * Individual projected 2026 budgets are staggering: **Amazon** ($200B), **Google** ($175B–$185B), **Meta** ($115B–$135B), **Microsoft** ($110B–$120B), and **Oracle** ($45B–$50B). * Capex is reaching seemingly untenable levels relative to revenue (e.g., ~86% for Oracle, ~54% for Meta, ~47% for Microsoft, ~46% for Google). * Looking long-term, Goldman Sachs projects the four largest hyperscalers will spend a combined **$5.3 trillion** in capital expenditures between FY2025 and FY2030. ### 2. The SB Energy IPO & Nvidia's $105B Guarantee To sustain this massive buildout, Nvidia is acting as a structured finance powerhouse, engineering its own demand through off-balance-sheet joint ventures and residual value guarantees. * On September 1, 2026, SoftBank's AI infrastructure arm, **SB Energy** (proposed ticker: `SBE`), filed for a Nasdaq IPO aiming to raise **$5 billion to $7 billion** at a potential market valuation of **up to $50 billion**. Despite having **zero operational data center revenue**, its valuation is propped up entirely by its relationships with Nvidia and OpenAI. * SB Energy is building the **PORTS-Pike Technology Campus in Ohio**, a flagship facility designed to draw 10 gigawatts of gross power load. OpenAI has leased approximately 8 gigawatts-IT under a 20-year lease. * Nvidia has backed this project with an unprecedented **$105 billion residual value guarantee**, leaving Nvidia on the hook if OpenAI defaults. Additionally, Nvidia is directly investing **$3 billion** in SB Energy as part of the offering. OpenAI has also received warrants worth an estimated **$5.5 billion** in SB Energy. * On September 10, 2026, Nvidia CEO Jensen Huang dismissed and mocked "circular financing" concerns at the Goldman Sachs Communacopia Conference, stating: **"Is that circular? If that is, let's do more of that... We put in one and 100 comes back in."** He defended these deals as a "sure thing," stating Nvidia has visibility into approximately **$100 billion of contracted customer demand**. ### 3. Supply-Chain Breakthrough: Samsung's Custom 8-Layer NVHBM To resolve the acute HBM memory supply bottlenecks that have gated GPU shipments, Nvidia is diversifying its supply chain. * In late August 2026, reports emerged that Samsung is building a custom 8-layer version of its HBM4E memory specifically for Nvidia, under a program designated **NVHBM**. * The custom chip targets pin speeds of **17-18 Gbps** (~20% faster than early HBM4E samples and faster than Samsung's standard 16 Gbps HBM4E shown at GTC 2026). * The **8-layer design represents a deliberate engineering trade-off**: sacrificing extreme stack capacity (which would require 12 or 16 layers) in exchange for higher yields, lower thermal output, and reliable volume production. * This custom part will exist alongside Samsung's standard HBM4E, which is destined for Nvidia's flagship **Vera Rubin Ultra** platform launching in the second half of 2027, securing a reliable secondary volume supplier to challenge SK Hynix's dominance. All notes have been updated and persisted in the system.
