> **RECONCILED 2026-07-22 — the $610–725B "conflict" fully dissolves; three axes explain all of it.**
> April-vintage highs: 190 (GOOGL) + 200 (AMZN) + 145 (META) + 190 (MSFT calendar) = **$725B**.
> February-vintage lows with Microsoft on a **fiscal** basis: 175 + 200 + 115 + 120 = **$610B**.
> The whole spread is (i) guidance vintage — three of four raised in April, (ii) Microsoft
> fiscal-vs-calendar (~$70B on one company), (iii) basket membership (four names vs five with Oracle).
> **This page's "the headline exceeds the sum of its own parts" flag was right against the parts it was
> holding and wrong against current ones** — the parts were stale, not the arithmetic.
> **Alphabet is also stale here:** $175–185B is the February guide, superseded 2026-04-29 by
> **$180–190B** with 2027 to "significantly increase" `[primary: GOOGL 8-K Ex-99.1, 2026-06-04]`.
> Current management-guided, calendar-year, lease-inclusive lines: **GOOGL $180–190B · AMZN ~$200B ·
> META $125–145B · MSFT $190B.**



> **RESOLVED 2026-07-22 — the Microsoft $190B vs $120B conflict was a DEFINITION ERROR, not a disagreement.**
> Primary, Amy Hood on the FY26 Q3 call 2026-04-29: *"For calendar year 2026, we expect to invest roughly
> $190 billion in capital expenditures"* `[primary: MSFT earnings call, 2026-04-29]` — **calendar** year,
> **including** finance leases, accrual basis (NOT the cash-flow-statement line, which cannot reproduce it).
> The "$120B+" figure has three candidate origins, all landing at $113–118B and none of them calendar-2026:
> (1) most likely a **six-month residual quoted as a year** — an analyst on that same call said "maybe to the
> tune of $120 billion" for the back half; $190B − $31.9B actual − $40B guided = $118.1B; (2) **CY2025 actual**
> ~$118.0B, which reconciles exactly with the "+61% vs 2025" framing in circulation; (3) fiscal-year AND
> cash-only (~$113B). Note fiscal-vs-calendar alone does **not** explain it.
> **Desk rule:** every capex figure must carry `(period basis, lease treatment)` or it is not comparable.
> For a big-four aggregate of management-guided, calendar-year, lease-inclusive capex, Microsoft's line is **$190B**.
> **Trap:** a real Microsoft number sits near $190B that is NOT capex — **$196.6B of leases signed but not yet
> commenced** (10-Q 2026-03-31), a five-year commitment stock, not an annual flow.



> **CORRECTION 2026-07-22 — Meta's figure below is STALE, verified against primary.**
> Every source in this topic quotes Meta at **$115–135B**. That is the FY2025 10-K number.
> Meta raised guidance to **$125–145B** on 2026-04-29, restated verbatim in the Q1-2026 10-Q
> MD&A: "capital expenditures of approximately $125 billion to $145 billion in 2026"
> `[primary: META 10-Q, 2026-04-30]`. Calendar year, **includes** finance-lease principal.
> **Consequence:** the reconciliation below says "the entire big-four gap is Microsoft, because
> Amazon, Alphabet and Meta are stated identically by both sources." Both sources agree on Meta
> because **both are stale on Meta** — agreement between two secondary sources of the same vintage
> is not corroboration. Every aggregate here understates Meta by $10B at both ends.
> Meta's run-rate is the live question: Q1-2026 spent $19.84B = 14.7% of the $135B midpoint
> (a flat year is 25%), so the bottom of its own range needs ~1.77x the Q1 quarterly rate held
> for three quarters. Prints 2026-07-29.



The hyperscaler capex cycle is the synchronized, debt-and-cash-funded capital spending of the four largest US cloud operators (Amazon, Microsoft, Google/Alphabet, Meta) on AI infrastructure. In 2026 that combined spend is guided to **~$725B, up from ~$410B in 2025 — a +77% YoY jump** — with a 2027 projection of **$1 trillion+**. This is the demand engine that sets the tape for every supplier above it in the stack: GPU vendors, datacenter shells, networking, cooling, and power. The defining behavioral driver, per Value Add VC, is asymmetric fear: "each company fears being structurally short on compute more than it fears overspending."

The spend is not monolithic — it splits roughly in half between **compute & silicon (~50%)** and everything that houses and powers it. About **~$260B+ goes to Nvidia GPUs** and **~$80B+ to custom silicon** (the hyperscalers' own accelerators), with the remaining ~50% flowing into datacenter plant (~35%) and power & grid (~15%). That allocation is the key to reading the cycle as an investment: the GPU line is the headline, but the plant and power lines are where the binding constraints — and the supply-chain re-rate — actually live (see [Power: The Binding Constraint](./power-the-binding-constraint.md)).

A second source (Data Center Knowledge) independently pegs 2026 hyperscale capex at **>$600B**. The two figures differ in scope — the ~$725B number is the big-four guidance total, the >$600B is a broader hyperscale framing — but they agree directionally that 2026 is a step-change spending year. The open tradable question the cycle raises is whether and when it inflects down, and what the leading indicator would be.

**Every aggregate on this page is a forecast.** These are guidance totals and analyst estimates for a year that is barely half over — not measured spending. No source in this KB reports a summed *actual* 2026 capex figure, and none can until the year closes.

## The 2026 Aggregate — Estimate Dispersion (added 2026-07-22)

A third source (Futurum, Feb 2026) puts 2026 capex at **$660–690B across five companies** (the big four plus Oracle), against a **~$380B** 2025 base. Reconciling it against the Value Add VC figures already on this page produces three distinct discrepancies, none of which the sources resolve:

| Discrepancy | Value Add VC (Jun 2026) | Futurum (Feb 2026) | Gap |
|---|---|---|---|
| 2026 aggregate | ~$725B (big four) | $660–690B (big four + Oracle) | The *lower* figure covers *more* companies |
| 2026 aggregate, big four only | ~$725B | $610–640B (derived: $660–690B less Oracle's $50B) | **$85–115B** |
| 2025 base year | ~$410B | ~$380B | $30B |
| Microsoft 2026 | ~$190B | $120B+ | **~$70B** |

Three things follow. First, **the entire big-four gap is Microsoft** — Amazon ($200B), Alphabet ($175–185B — **STALE, actual $180–190B**) and Meta ($115–135B — **STALE, actual $125–145B**, see correction above) are stated identically by both sources; only Microsoft differs, and it differs by roughly the size of the whole discrepancy. Second, **the ~$725B headline exceeds the sum of its own per-company parts**: Value Add VC's four figures sum to **$680–710B**, $15–45B short of its own $725B headline — an internal reconciliation gap in the source this KB has been quoting. Third, the vintage difference (Feb vs Jun 2026) plausibly explains part of the Microsoft gap, since Futurum's "$120B+" is open-ended and predates two quarters of upward revisions — but no source states that reconciliation, so the KB records the conflict rather than picking a number.

**Working position:** treat **$610–725B** as the honest band for 2026 big-four capex and stop quoting ~$725B as a settled figure. The band closes only when summed actual quarterly capex is available.

## The prints arrive — the demand side has stopped self-funding (added 2026-07-23)

The first Q2 2026 primary prints turn this page's central open question — *is the buildout financed from operating cash flow or from the balance sheet?* — from hypothesis into an on-print fact for two named buyers. **The demand side of the buildout has stopped self-funding.** Every capex figure here is stated with its `(period basis, lease treatment)` per the desk rule.

- **Alphabet — Q2 capex $44.9B `(calendar-Q2 2026 actual; cash purchases of PP&E from the cash-flow statement — excludes finance-lease additions)` outran operating cash flow $39.1B, so quarterly free cash flow went NEGATIVE $(5.9)B.** The gap was plugged from capital markets, not operations: a **$49.6B June equity raise** explicitly earmarked "to scale AI infrastructure," plus **$20.3B of senior notes**; long-term debt more than doubled to $98.2B in six months. `[primary: GOOGL 8-K Ex-99.1, 2026-07-22]`
- **Tesla — Q2 capex $5.79B (+142% YoY) `(calendar-Q2 2026 actual; cash PP&E purchases)` outran OCF $4.7B, so FCF went NEGATIVE $(1.1)B** — its first negative-FCF quarter since Q1 2024. Tesla did *not* tap capital markets; it drew its cash pile down **$1.2B** to $43.5B. Same signal, different funding valve. `[primary: TSLA 8-K Ex-99.1, 2026-07-22]`

Two things this settles and one it does not. It **settles the financing-fragility question** (previously open on this page): for the two names that have printed, capex now exceeds internal cash generation, and the buildout is carried by the balance sheet — Alphabet by external capital, Tesla by cash drawdown. It **partially breaks this page's "every aggregate is a forecast" caveat**: there are now *actual* quarterly capex figures on the tape for two buyers, even though the summed-year big-four aggregate is still unmeasured. It does **not** resolve the FY guide — Alphabet's Ex-99.1 carries **no FY2026 capex dollar guide and no RPO/backlog line** (both are call/10-Q items). The Q2 run-rate ($44.9B) annualizes to ~$180B and H1 ($80.6B) to ~$161B, but the printed release neither confirms nor breaks the pre-print's watched $180–190B — mark it **unresolved by the print** and do not invent it.

**The supply-side mirror (TXN).** Texas Instruments — a *seller* into the buildout, now naming "data center" a growth leader — printed the opposite profile: revenue **$5.46B** (above the $5.00–5.40B guide top), its own **capex falling** ($4.94B → $3.31B TTM as its 300mm fab wave crests), and **free cash flow +271% YoY to 33.6% of revenue** (definition includes CHIPS Act incentive proceeds). The seam this topic tracks, now visible on one tape: the buyers' funding gaps widen while the equipped, subsidised supplier harvests the cash. `[primary: TXN 8-K Ex-99, 2026-07-22]`

- **Alphabet's guidance was revised upward repeatedly** — from an initial $71–73B projection to $175–185B across three revisions, per Futurum; the July preview reports a further raise to **$180–190B**. *Evidence: weak (analysis + summary-derived figures in a paywalled preview)* ([Futurum](../../raw/futurum-hyperscaler-capex-2026-690b.md)); ([Alphabet preview](../../raw/alphabet-q2-2026-earnings-preview.md))

### Added 2026-07-23 (first primary Q2 prints)

- **[ACTUAL] Alphabet Q2 2026 capex $44.9B `(calendar-Q2 actual, cash PP&E purchases)` exceeded operating cash flow $39.1B → free cash flow NEGATIVE $(5.9)B**, funded by a $49.6B equity raise + $20.3B senior notes (LT debt doubled to $98.2B). *Evidence: strong (first-party 8-K)* ([GOOGL Q2 2026](../../raw/googl-q2-2026-earnings.md))
- **[ACTUAL] Tesla Q2 2026 capex $5.79B (+142% YoY, calendar-Q2 actual) exceeded OCF $4.7B → FCF NEGATIVE $(1.1)B**, self-funded by a $1.2B cash drawdown, no capital raise. *Evidence: strong (first-party 8-K)* ([TSLA Q2 2026](../../raw/tsla-q2-2026-earnings.md))
- **The demand side has stopped self-funding** — for both buyers that have printed, Q2 capex exceeded operating cash flow; the buildout is now carried by the balance sheet rather than operations. *Evidence: strong (two first-party 8-Ks)* ([GOOGL](../../raw/googl-q2-2026-earnings.md)); ([TSLA](../../raw/tsla-q2-2026-earnings.md))
- **Supply-side mirror: TXN Q2 2026 revenue $5.46B (beat the $5.00–5.40B guide top), capex falling $4.94B→$3.31B TTM, FCF +271% YoY to 33.6% of revenue** — the equipped seller harvests as the buyers' funding gaps widen; "data center" named a growth leader. *Evidence: strong (first-party 8-K)* ([TXN Q2 2026](../../raw/txn-q2-2026-earnings.md))
- **Google Cloud accelerated to $24.8B (+82% YoY) at a 35.6% operating margin** — the segment funding the capex is itself inflecting up; Cloud now books TPU-system sales as product revenue (own-silicon value capture). *Evidence: strong (first-party 8-K)* ([GOOGL Q2 2026](../../raw/googl-q2-2026-earnings.md))
- **[UNRESOLVED BY THE PRINT] Alphabet's FY2026 capex dollar guide and RPO/cloud backlog are absent from the Ex-99.1** (call/10-Q items) — the watched $180–190B guide and ~$462B backlog can be neither confirmed nor broken from the release; not invented here. *Evidence: n/a (absent from primary source)* ([GOOGL Q2 2026](../../raw/googl-q2-2026-earnings.md))

## Open Questions

- **Will hyperscaler capex inflect down at any point, and what is the leading indicator?** (Frontier debate #4.)
- **Which Microsoft number is right — ~$190B or $120B+?** A ~$70B single-name gap is the largest unresolved figure in this topic and drives the entire aggregate dispersion. Resolving it requires Microsoft's own disclosure, which this KB does not have.
- **Why does the ~$725B headline exceed the sum of its own per-company parts?** Either the headline includes something the four figures do not, or one of them is wrong.
- Reconciling the ~$725B (big-four) vs >$600B (broader hyperscale) vs $660–690B (five-company) figures — what exactly does each scope include?
- Does the growing weight of first-party builders (see [Vertically Integrated Compute](./vertically-integrated-compute.md)) mean the big-four aggregate systematically understates total AI-datacenter capex?
- How much of the 2026 spend is debt-financed vs funded from operating cash flow, and does that change the cycle's fragility? **(Partially answered 2026-07-23: for the two names that printed, Q2 capex now exceeds OCF — Alphabet funded the gap from capital markets, Tesla from a cash drawdown. The remaining question is how long negative FCF can run before it constrains the buildout, and whether Amazon/Microsoft/Meta show the same when they print.)**
- Does the custom-silicon line (~$80B+) erode Nvidia's ~$260B+ share over the cycle?
- What return-on-invested-capital does $725B/year actually earn — is the spend justified by realized AI revenue, or front-running it?

- [Rack Power Density](./rack-power-density.md) — the NVL72 density step-change is what makes each capex dollar buy more compute (and more cooling load)

## Changelog
- 2026-06-24 — Created from 2 sources (ai-hyperscaler-capex-2026, hyperscaler-power-bottleneck-2026)
- **2026-07-22** — Added a third 2026 estimate ($660–690B, Futurum) and recorded three unresolved conflicts (big-four aggregate $725B vs $610–640B derived; Microsoft ~$190B vs $120B+; 2025 base $410B vs $380B), plus an internal inconsistency in the $725B headline vs its own per-company sum. Widened the working band to $610–725B, labelled all aggregates as forecasts, and added Oracle's $50B figure (closing a previously-flagged gap).
- **2026-07-23** — Folded in the first primary Q2 2026 prints (GOOGL, TSLA, TXN 8-Ks). New spine finding: **the demand side has stopped self-funding** — Alphabet ($44.9B capex > $39.1B OCF → FCF $(5.9)B, funded by $49.6B equity + $20.3B notes) and Tesla ($5.79B capex > $4.7B OCF → FCF $(1.1)B, self-funded by cash drawdown). Added TXN as the supply-side mirror (capex rolling off, FCF +271%). Every capex figure now carries its (period basis, lease treatment). Alphabet's FY capex guide and RPO marked unresolved-by-the-print (absent from the Ex-99.1). Partially answered the debt-vs-cash-flow financing question.
