Evidence

Nvidia earnings-call statements + Goldman Sachs research + investor-press synthesis

The dominant AI compute supplier has repeatedly floated a data-centre capex projection roughly four times current spend.

The details

On multiple occasions, Nvidia has asserted that global data-centre capital expenditures will reach $3 trillion to $4 trillion annually by 2030, The Motley Fool noted this week, against roughly $650 billion in planned 2026 spend from the big four hyperscalers.
Goldman Sachs' baseline model implies $765 billion in annual AI capex in 2026 growing to $1.6 trillion in 2031](https://www.goldmansachs.com/insights/articles/tracking-trillions-the-assumptions-shaping-scale-of-the-ai-build-out) — roughly half of Nvidia's high case.
Nvidia's own projection implies a 46% compound annual growth rate in data-centre capex from here to 2030.

What it means

Nvidia is the vendor most exposed to the figure being wrong, which is what makes its persistence interesting. The gap to Goldman's midpoint — 2x by 2031 — is the real argument, and it turns on whether inference stays on GPUs or moves to custom silicon (story 03). Treat the number as a supplier's upper bound, not consensus.

Counterview

Every prior technology-buildout projection from the dominant supplier — Cisco on fibre, Intel on PC units — has overshot the actual capex peak by a factor Wall Street eventually punished.
