Global AI investment set to breach $1 trillion threshold during 2026

Capital Supercycle Accelerates| Hyperscaler forecasts miss broader technology infra spending boom

Global artificial intelligence investment is forecast to reach $1.019 trillion in 2026, around $200 billion above the widely cited hyperscaler capital expenditure estimate, according to Goldman Sachs Research, signalling that the AI investment cycle is considerably larger — and less US-centric — than headline numbers suggest.

The commonly used benchmark is capital expenditure by major US hyperscalers. Consensus analyst estimates suggest these technology companies will spend about $800 billion this year, with a widely referenced forecast putting the figure at $794 billion.  Goldman Sachs Research, however, says that measure presents an incomplete picture. 

Spending gap: Hyperscaler estimates exclude AI investment by private companies and businesses outside the US. At the same time, not every dollar of hyperscaler capital expenditure is necessarily AI-related.   There is another important distortion: large American technology companies operate globally, meaning part of their investment occurs outside the US even though their overall expenditure is frequently treated as American AI spending.

Goldman Sachs Research adjusted these measures to produce a broader assessment of the investment cycle. Joseph Briggs, who co-leads the firm’s Global Economics team, said the resulting estimate points to $1.019 trillion of AI-related investment globally in 2026, of which $581 billion is expected to take place in the US.

Global Shift: The recalculation changes both the size and geographical composition of the AI investment story.  Goldman Sachs Research estimates that the frequently cited $794 billion hyperscaler capex forecast understates worldwide AI investment by roughly $200 billion. Conversely, it probably overstates US investment by about $200 billion.

That suggests substantial spending is taking place beyond America's technology giants, broadening the investment cycle across private companies and overseas markets. Market Impact: The findings matter because hyperscaler budgets have become a key gauge for investors assessing the durability of AI-led capital spending. 

A broader $1 trillion-plus global investment pool suggests the economic effects could extend well beyond semiconductor manufacturers and leading technology companies. Data centres, electricity generation and transmission, networking infrastructure, cooling systems, construction and specialist equipment could increasingly capture spending generated by the build-out. 

The geographical shift is equally significant. With only $581 billion of the projected $1.019 trillion occurring in the US, roughly $438 billion would be deployed elsewhere. Goldman Sachs' analysis therefore reframes the AI investment narrative: the capital wave is not merely larger than conventional estimates imply, but substantially more global. Crossing the $1 trillion mark in 2026 would underline AI's evolution from a technology spending boom into a worldwide infrastructure investment cycle.
