Big Tech AI capex to hit $1.2 trillion by 2027, Goldman Sachs projects
Goldman Sachs forecasts that the five largest cloud and tech firms will collectively invest $1.2 trillion in AI infrastructure during 2027, representing a 50 percent acceleration from current spending levels. This capital intensity rivals historical infrastructure booms like 19th-century railroad expansion when measured as a share of GDP. The projection signals that AI buildout remains the dominant capital allocation priority for Big Tech, though the analysis flags emerging constraints in power supply, semiconductor availability, and skilled labor that could moderate the trajectory. The scale underscores how AI infrastructure has become the primary driver of tech capex cycles.
Modelwire context
Analyst takeThe $1.2 trillion figure is a forward projection for a single year (2027), not a cumulative multi-year estimate, which makes the implied year-over-year acceleration even steeper than headline coverage suggests. Goldman is essentially arguing that the spending curve has not yet bent, despite persistent analyst expectations that it would.
This is largely disconnected from recent activity in our archive, as we have no prior coverage to anchor it to. It belongs to the capital expenditure and AI infrastructure beat, sitting alongside coverage of hyperscaler earnings calls, data center power procurement, and semiconductor supply chain dynamics. The Goldman projection is most usefully read as a counterpoint to the recurring 'capex peak' narrative that surfaces each earnings season when one of the five named firms posts a quarterly miss.
Watch whether Amazon and Alphabet's Q4 2026 earnings guidance (due late October and late January respectively) revises infrastructure capex targets upward toward the per-company run rates implied by Goldman's $1.2 trillion aggregate. If both firms hold or cut guidance, the projection loses its near-term credibility.
