The grid, not the GPU, is now the bottleneck

AI has turned the data center from a real-estate footnote into the single most capital-intensive build-out of the decade. Hyperscaler capex surged sharply in 2025 — with data center capex growing roughly 59% year-on-year in the third quarter alone — and worldwide data center capex is forecast to clear $1 trillion later this decade. Yet vacancy sits near 1.4% and the binding constraint has shifted from chips to megawatts.

01 · The thesis

Capital is abundant; power and time are not

The demand signal is unambiguous. A large volume of data center capacity was under construction globally through late 2025, the bulk of it in the US, and roughly 74% of capacity under construction is pre-committed — leases or owner-occupied — often for delivery in 2027 and beyond. Record-low vacancy means this is not a 2000-era overbuild: tenants are the most creditworthy companies on earth, and power-interconnection delays are themselves throttling supply faster than any discipline a developer could impose.

The risk has migrated from demand to the grid and the balance sheet. PJM came up roughly 6,625 MW short in its December 2025 capacity auction and expects its first capacity shortfall by summer 2027; data center load growth is outpacing new generation roughly 2-to-1. The winners are those who control power, land and interconnection queues — and who can finance multi-gigawatt projects with single-tenant offtake. The exposure is concentration: neoclouds with backlogs leaning on one or two hyperscale counterparties, and ratepayers who may absorb stranded-cost risk if the AI capex curve ever bends.

Megawatts are the new moat

Interconnection queues, PPAs and nuclear offtake now gate every project; whoever secures firm power wins the site.

03 · The two clocks

The spend, and the payoff

Three clocks the sector is racing against

Source: company filings and IR (Vertiv, CoreWeave, Digital Realty) and Crusoe/Blue Owl JV disclosures, 2025-2026.

The power clock. S&P Global projects data center grid demand rose sharply in 2025 and roughly triples by 2030; Epoch AI estimates US AI data centers will need 20-30 GW by late 2027. Demand is arriving in gigawatt blocks the grid cannot energize on schedule.

The build clock. Vacancy at a record 1.4% and ~74% pre-commitment mean capacity is spoken for years ahead, but power-interconnection and equipment lead times now stretch project timelines well past approval, pushing real delivery risk onto tenants who have already booked the space.

The capital clock. With worldwide capex forecast to approach $1 trillion later this decade and hyperscalers each raising spend at double-digit-to-triple-digit rates, the question is no longer whether demand exists but whether single-tenant offtake and debt-heavy neocloud balance sheets can survive any pause in the AI spending curve.

04 · Private flagships

The AI-native challengers

The companies attacking this industry AI-first, with disclosed funding where available:

CoreWeave

The neocloud bellwether

Converts contracted Nvidia GPUs and power into multi-year compute backlogs sold to OpenAI, Meta and Microsoft; the purest public proxy for AI infrastructure demand — and its concentration risk.

FY2025 revenue $5.13bn (+168%); $66.8bn backlog at YE2025 rising to $99.4bn by Q1 2026 (SEC/CNBC).

Crusoe

Vertically integrated AI-factory developer

Builds gigawatt campuses tying power generation to compute; anchor of the Stargate Abilene site and now pushing into modular, grab-and-go data centers.

$1.375bn Series E at ~$10bn valuation; ~$15bn Abilene JV with Blue Owl and Primary Digital (Crusoe).

Vertiv

The arms dealer of the build-out

Supplies the power and liquid-cooling backbone every AI hall now requires; a 2.9x Q4 book-to-bill makes it a leading indicator for the whole pipeline.

Q4 2025 net sales ~$2.88bn; $15.0bn backlog, +109% YoY (Vertiv IR).

Stargate (JV)

The trillion-dollar moonshot

OpenAI, SoftBank, Oracle and MGX building toward 10 GW of dedicated AI capacity; the project that recast data centers as national-scale infrastructure.

$500bn over four years; multiple sites and hundreds of billions committed by late 2025 (OpenAI).

Digital Realty

The institutional REIT pivot

Repositioning a global colo portfolio toward AI training and inference, with power-bank allocations now the scarce resource it leases.

$1.2bn 2025 bookings, ~$1.4bn record backlog, AI >50% of bookings (Investing.com).

What moved, and what to watch

Dec 2025

PJM capacity auction falls ~6,625 MW short

Stargate expands across new sites

OpenAI's JV adds capacity toward its 10 GW target, with hundreds of billions committed across sites.

06 · The exposure read

Who’s defensible, who’s at risk

AI rewards clean, structured advantage and punishes friction. The line runs through who owns the data, the brand and the customer — and who is merely a step the technology can route around.

Defensible

  • Power-controlling landlords and hyperscalers — operators who lock firm megawatts, interconnection slots and nuclear/PPA offtake convert scarcity into pricing power; Digital Realty's power-bank allocations are now its scarcest asset.
  • Picks-and-shovels suppliers — Vertiv and the liquid-cooling and electrical-gear vendors enjoy 2.9x book-to-bill and multi-year backlogs regardless of which tenant ultimately wins.
  • Creditworthy long-lease REITs — with ~74% pre-commitment and 1.4% vacancy, scaled colo REITs leasing to investment-grade tenants capture durable, contracted cash flows.
  • Vertically integrated developers — Crusoe-style players that own generation, shell and compute capture margin across the stack and de-risk the power bottleneck others face.

At risk

  • Single-tenant neoclouds — CoreWeave-style backlogs (around $67bn at YE2025, $99bn by Q1 2026) rest on a handful of hyperscale counterparties; any AI-capex pause exposes leverage built for a curve that only goes up.
  • Speculative merchant developers — anyone building without firm power or signed offtake faces years of interconnection delay and stranded capital, the opposite of the pre-leased majority.
  • Ratepayers and laggard utilities — CNBC and Forbes flag the risk that households absorb higher bills or stranded-cost exposure if gigawatt-scale load fails to materialize as contracted.
  • Sub-scale legacy colo — facilities that cannot support 30kW+ liquid-cooled racks are stranded against AI-grade demand concentrated in a few power-rich corridors.
The data center has become the physical balance sheet of the AI boom: abundant capital chasing scarce megawatts. The sector's near-zero vacancy is genuine strength, but it is also a measure of how little slack remains if the power clock, the build clock or the capital clock slips. Watch the grid auctions and the neocloud backlogs, not the GPU headlines.
