Power is Everything in AI. $100 Billion Per Gigawatt of Data Center

The AI race is shifting from who has the best model to who can actually deploy and access the most reliable gigawatts of compute at scale.

In a recent All-In podcast episode, Chamath stated that a full 1 GW AI data center now costs around $100 billion to build. The Milk Road AI post you linked highlights that when Chamath started the Arizona project, the figure was roughly $4–5 billion (or ~20x lower than today’s estimates).

This $100B figure covers the entire facility:Land, buildings, and site work.

Massive power infrastructure (substations, transformers, high-voltage cabling — copper shortages are a real issue)
Advanced cooling systems
Networking
And especially the compute hardware itself (GPUs/servers — often ~60% of total cost)

Only a handful of players can realistically build at meaningful scale with multi-GW clusters needed for frontier training/inference. This favors hyperscalers (Microsoft/OpenAI, Google, Amazon, Meta), heavily funded specialists, and deep-pocketed entities (SpacexAI/Elon’s Colossus expansions).

Neoclouds (specialized GPU cloud providers like CoreWeave, Nebius, Lambda) gain relative advantage. They focus narrowly on AI compute, avoid hyperscaler overhead, and can price 60–85% cheaper on equivalent Nvidia silicon.

Power is the primary bottleneck for AI, Data centers follow power availability, not the other way around. Utilities, independent power producers, nuclear operators, gas plant owners, and even former crypto miners (with existing high-power sites) are extremely well-positioned.
