Amazon, Alphabet, Microsoft and Meta will spend $760 billion on AI infrastructure this year, 80% more than last year, and Nvidia's chief says the build reaches $3 to $4 trillion by 2030. Jon, spray-painting a friend's loft wall: calling AI a gadget is like calling electricity a lamp.

The tape this month: the four hyperscalers are expected to spend $760 billion on AI infrastructure capex in 2026, an 80% increase on 2025 (news on the tape, 12 Sept); Amazon alone has raised its 2026 capital spending to $220 billion (9 and 11 Sept); Jensen Huang reaffirmed on 17 September that AI infrastructure spending reaches $3 to $4 trillion by 2030, the same forecast he made a year earlier to the day; Nvidia is the world's largest company at $5.1 trillion (16 Sept). The physical layer is on the tape too: the Census Bureau's data-centre line ran at $6.55 billion of construction work in July 2026, up 58% on a year earlier and 10.2% of all private non-residential building in America. Jon's point, sprayed on brick: this is not a product cycle, it is a build-out, the way the internet went from somewhere you went to the layer under everything.

in plain EnglishThe biggest technology companies are spending sums on AI this year that look like national infrastructure budgets: three quarters of a trillion dollars on buildings, power and chips, most of it not visible to anyone using a chatbot. Jon, at a friend's loft painting a mural of the skyline, argues that is the point: AI is turning into infrastructure, like electricity or the internet, and calling it a gadget misses what the money is doing.
