Hyperscalers raise 2026 capex to $725 billion

Microsoft, Alphabet, Amazon and Meta confirmed a combined $725 billion of 2026 capital spending in late-April earnings, up 77 per cent on 2025, with no downward revision after Maine's veto, Seattle's freeze, or the Iran energy shock.

Key takeaway

Hyperscaler capital plans absorbed the moratorium wave intact; the binding constraint shifted to the supplier side.

Late-April Q1 2026 earnings calls from Microsoft, Alphabet, Amazon, and Meta confirmed a combined $725 billion of 2026 capital expenditure, up 77 per cent from 2025's $410 billion record . That works out to roughly $2 billion of new infrastructure spend every day this year, around three-quarters of it AI-related. Microsoft's AI business cleared a $37 billion annual run rate in fiscal Q3, up 123 per cent year-on-year. Google Cloud's customer backlog jumped past $460 billion. Amazon spent $44.2 billion in a single quarter and reaffirmed a full-year plan approaching $200 billion. Meta raised both ends of its 2026 guidance by $10 billion to $125-145 billion.

None of these numbers moved when Maine voted, when Seattle froze, when Compass walked away from Prince William. Capital allocation cycles quarterly inside hyperscaler boards; consent cycles through ballots, hearings, and litigation calendars on five-to-eight-year clocks. Microsoft's $37 billion AI run rate is the structural change inside the prints rather than the headline aggregate, because it is the threshold at which AI revenue can be argued to fund AI capex on a forward basis without diluting existing shareholders. Meta is in a different position: capex is rising faster than monetisation can plausibly catch up, which is why a 16,000-job restructuring lands alongside the $10 billion guidance increase.

The consequence shows up at the supplier end. GE Vernova's Q1 backlog rose from 83 GW to 100 GW in a single quarter , with $2.4 billion of data-centre electrification orders in the quarter alone, exceeding the whole of 2025. Customers pulled aggressively into 2030, and roughly 10 GW of available production capacity remains across 2029 and 2030 combined. The behind-the-meter gas escape, the standard route round a slow grid queue, has now become its own queue paced by factory throughput rather than utility planning. Capital can outrun consent, because consent cannot lobby a 2030 turbine slot. It cannot outrun a turbine that has not been built yet.

Deep Analysis

In plain English

The four largest US tech companies, Microsoft, Google's parent Alphabet, Amazon, and Meta, announced in their quarterly results that they plan to spend a combined $725 billion on data centres and related infrastructure in 2026. That is roughly 77 per cent more than they spent in 2025. None of them cut spending plans despite the growing number of cities and states trying to pause data centre construction. All $725 billion is formally allocated in corporate capital plans. The problem is that spending the money does not automatically produce operating data centres: the gas turbines used to power them independently of the grid have a manufacturing queue booked until 2030, and the planning hurdles described elsewhere in this briefing add years to timelines in the US market.

Deep Analysis
Root Causes

Three physical constraints are structurally independent of the capital allocation: turbine slots, transformer lead times, and consent.

GE Vernova's 100 GW backlog as of Q1 2026, with approximately 10 GW of available capacity remaining across 2029-2030 combined, means that any behind-the-meter generation strategy announced by a hyperscaler today competes for equipment slots that are essentially exhausted. This is not a price problem, it is a manufacturing-capacity problem that cannot be resolved by paying more.

Transformer lead times for large power transformers (the 100-MVA-plus units data centres require at grid-connection points) are 18-24 months from domestic US suppliers and 12-18 months from European and South Korean suppliers. The US transformer manufacturing base (ABB in Mount Pleasant, SC; Eaton in Pittsburgh; and a small number of others) operates at roughly 85-90 per cent of rated capacity, with no new greenfield transformer plants expected before 2028.

The consent layer, detailed in events 0-3 of this briefing, now adds 12-36 months to North American siting timelines in a way that was not priced into 2024-2025 site-acquisition models.

What could happen next?
  • Consequence

    Hyperscalers routing capital away from the US consent-constrained markets will accelerate build-out in Nordic, Gulf, and Iberian locations where consent and grid timelines are shorter, concentrating new capacity outside the US faster than current market-share projections assume.

  • Risk

    If GE Vernova or Siemens Energy cannot expand turbine production capacity by 2027, the behind-the-meter generation strategy that US hyperscalers adopted as a grid bypass (xAI's 41-turbine Colossus installation, Meta El Paso's 366 MW) will not be replicable for projects committed in 2026.

This Event
Hyperscalers raise 2026 capex to $725 billion
Capital allocation runs on quarterly board sign-off; consent runs on years of hearings and litigation. The asymmetry is the structural driver of where data centres land.

All four reported Q1 2026 earnings with no downward revision to combined 2026 capex of $725 billion, treating the moratorium wave as a routing problem rather than a demand signal. Microsoft's $37 billion AI annual run rate confirms that capital allocation runs on quarterly board cycles that five-to-eight-year consent timelines cannot disrupt.
