Google's Compute Domination

Premium Analysis

Here is the most important structural fact in AI infrastructure right now: Google’s TPU fleet grew 11.5x in seven quarters, it now draws more power than Microsoft’s entire AI compute stack, and the quarterly rate of additions is itself accelerating.

By Q4 2025, Google had added more compute in a single quarter than xAI has built in total.

That is the data point. The analytical question — the one that matters for understanding where the AI industry goes from here — is what it cascades into.
