+$315B / +77%
Largest single-year increase ever. ~$25B is memory-cost inflation per Microsoft's CFO, not new capacity.
Forward read
Capacity-constrained
Power, transformers, and HBM lead times, not capital, are now the binding constraint on what gets built.
Cliff · Where the $725B goes
$725B 2026 hyperscaler capex, by category
Hyperscalers don’t disclose this split — analysts back into it from supplier revenue and capacity guidance, and estimates vary ±15–30% by methodology.
AI accelerators
NVIDIA GPUs · custom ASICs (TPU / Maia / Trainium / MTIA) · AMD <5%
NVIDIA FY26 DC revenue $193.7B with hyperscalers >50% of that → ~$130-160B Big 4 share once calendar/Blackwell ramp accounted for. Custom ASIC via Broadcom (Google TPU ~$22B alone) + Marvell Trainium add ~$35-45B. AMD MI400 ramp adds ~$5-8B Big 4.
Non-AI / traditional cloud
Storage · CPU compute · existing services · refresh
Goldman / Futurum consensus: 75% AI / 25% non-AI of $725B → ~$181B baseline. Roughly flat YoY in absolute dollars. Includes legacy CPU refresh, HDD/SSD, AWS retail/logistics, Office/Workspace serving.
Servers, networking, cooling
CPUs · switching ASICs · liquid cooling · optics · DPUs
Vertiv 2026 guide $13.25-13.75B (most → hyperscalers); Eaton-Boyd Thermal $1.7B liquid cooling 2026; Schneider DC ~$10B+. Switching/optical (Broadcom non-AI + Marvell + Arista + Cisco DC) ~$25-35B. Server CPUs (Intel + AMD) ~$20-30B.
Data center construction
Shells · on-site electrical · structural · land
ConstructConnect: US DC construction SAAR $50B (March 2026, +34% YoY). ~70% hyperscaler share → ~$35B US Big 4. International (Microsoft EU/Asia, Google global, Meta, AWS regions) adds $30-40B. On-site electrical (transformers, switchgear, UPS) is capitalized here.
Power infrastructure & PPAs
Off-site only · utility upgrades · PPA prepayments · generation equity
Discrete deals: Google–Intersect Power $4.75B (2026), Microsoft–Three Mile Island commitment, Meta nuclear PPAs >6 GW signed Q1 2026, Amazon $20B AWS Pennsylvania (partly construction). PPA prepayments often aren't on the GAAP capex line.
Memory premium (look-through)
Incremental DDR5 only — HBM lives inside accelerator BOM
HBM 2026 TAM $45-55B (Goldman / BofA), but Big 4 buys it embedded in NVIDIA/Broadcom silicon counted in AI accelerators above. The standalone line is the marginal premium DDR5 server DRAM Big 4 procures directly. SK Hynix 62% / Samsung 17% / Micron 11% of HBM.
The cleanest anchor across all sources
Goldman + Futurum converge on 75% AI / 25% non-AI of the $725B → $545B AI infrastructure, $180B traditional cloud baseline. Every category above is a slice inside that 75/25 split, with overlaps noted (memory look-through, on-site vs off-site power).
Where the dollars flow downstream
NVIDIA · TSMC · SK Hynix / Samsung / Micron · Broadcom · Marvell · AMD · Vertiv · Schneider Electric · Eaton · GE Vernova · Siemens Energy · Quanta Services · Jacobs · Turner · IPPs & investor-owned utilities (long-dated PPAs, transmission upgrades).
All four hyperscalers reported Q1 2026 earnings April 29 and collectively raised 2026 capex guidance to $725B vs $410B actually-spent in 2025 — a 77% YoY increase. Microsoft set 2026 capex at $190B (well above the $152B analyst consensus); CFO Amy Hood disclosed that approximately $25B of the $190B figure is attributable to memory-chip and component cost increases (DRAM, HBM, storage), not to additional data-center capacity. Alphabet/Google raised 2026 capex guidance to $180-190B (from prior $175-185B), with Google Cloud Q1 revenue at $20B growing faster than competitors by percentage. Meta raised 2026 capex guidance to $125-145B (from prior $115-135B), explicitly citing 'expectations for higher component pricing this year and, to a lesser extent, additional data-center costs to support future-year capacity.' Amazon's AWS Q1 revenue was $37.6B with $8.3B of YoY growth (largest absolute dollar add of the four). Across all four, the consistent disclosed driver is component cost inflation — memory chips in particular — being passed through to capex rather than absorbed by margin compression.

Why it matters
Three macro updates for the firm-equivalent-mw underwrite. (1) The $725B combined 2026 capex is a $315B YoY increase from 2025's $410B — that's a ~$26B/month incremental construction-and-equipment outlay across the four hyperscalers, and it lands on a US data-center supply chain that's already absorbing the Tom's Hardware-disclosed 'half of 2026 pipeline canceled or delayed' bottleneck (covered Tuesday). The math implication: capex *commitments* are growing 77% but actual *deliverable* capacity is constrained by power infrastructure, transformer / switchgear lead times, and now memory-chip pricing pass-through; the gap between committed-capex and built-capacity is widening, which means the marginal site that actually *can* be built and powered in 2026 has a higher willingness-to-pay than 2025's marginal site. Cliff's submission-readiness wedge is selling speed-to-approval into a market where speed-to-energization is the binding constraint, and the 77% capex-growth signal validates the wedge's pricing power upward. (2) Microsoft's $25B-of-$190B memory-chip disclosure is the first time a hyperscaler has cleanly separated 'capex for capacity' from 'capex for component-cost inflation' in earnings disclosure. This matters for green-loan-data-center-financing.md because lenders underwriting against capex-as-collateral need to discount the inflation-driven portion (it doesn't add operational capacity) versus the capacity-driven portion (it does). The 13% inflation share at Microsoft is a starting benchmark; Meta's similar 'higher component pricing' disclosure suggests the share is similar across the four. Bilateral-DC-debt deals (Meta's $13B El Paso, Oracle's $300B Stargate-restructured commitment) should price against capacity-only capex, not gross capex. (3) Google Cloud's $20B Q1 (growing fastest by percentage of the four) is the strongest signal yet that hyperscaler-DC demand is being driven by *cloud* AI inference, not just LLM training — Q1 2026 is the first quarter where Google Cloud's growth rate decisively outpaces AWS and Azure on a percentage basis, and the underlying demand mix is shifting toward GPU inference (Anthropic, OpenAI competition) plus vertical-specific AI applications rather than pure compute-and-storage. The site-selection implication: latency-to-end-user starts to matter for inference workloads in a way it never did for training, which favors metro-adjacent siting (Northern VA, North Texas, Phoenix metro, Atlanta) over remote stranded-asset siting (West Texas, Wyoming, rural Utah). Watch whether 2026 hyperscaler announcements skew metro-adjacent vs remote-asset compared to 2025; if so, the BTM-gas / retired-coal-site geographic-arbitrage thesis (covered Wed/Thurs) needs to weight metro proximity more heavily in the firm-equivalent-mw model.
