Global AI Compute Grows 8.5× by Q4 2025
Between Q1 2024 and Q4 2025, tracked global AI compute capacity—measured in H100-equivalent units—increased from roughly 2.5 million to 21.3 million, an 8.5× expansion over eight quarters. The rapid scale-up is described as a structural transformation of who controls the physical compute substrate for future AI-driven economies. Observed deployment patterns (who is building, pace, chip choice, and architecture) suggest that a small set of major technology organizations are strategically competing to own the AI infrastructure layer, with implications beyond simple hardware procurement.
Rapid, large-scale expansion of AI compute capacity—and its concentration among a few major organizations—reshapes control over foundational AI infrastructure, affecting model access, costs, vendor power, and the future development of AI-enabled products and services across industries including AdTech.

Key Takeaways & Evidence Grounding
- Tracked AI compute capacity rose from ~2.5 million H100-equivalent units in Q1 2024 to 21.3 million in Q4 2025.
- The increase represents an 8.5× expansion in total tracked AI compute over eight quarters.
- The author characterizes this change as a structural transformation in control of AI physical infrastructure.
- Patterns in build pace, chip suppliers, and architecture indicate a competition among five or six major organizations to own the AI infrastructure layer.

Seven Mental Models for the AI Compute Era
This analysis argues that public attention on model releases, parameter counts and benchmarks misses the more important story: a physical infrastructure race beneath the model layer. It reports that tracked AI compute capacity grew roughly 8.5× between Q1 2024 and Q4 2025 — from 2.5 million to 21.3 million H100-equivalent units — and frames that expansion as a contest over power: who controls the compute substrate, builds strategic independence, or becomes dependent on single suppliers. The author proposes seven transferable mental models to map these structural dynamics, suggesting conventional frames (market share, revenue, roadmaps) fail to capture long-term winners determined by 2024–2025 infrastructure bets.
AI Accelerators Break 50-Year Compute Trend
Exponential View published a research report, The State of the AI Economy, highlighting a break in a 50-year trend of global compute growth. The author says the global stock of compute grew at roughly 66% compounded annually until about 2023, and that the arrival of AI accelerators since 2020 has created a new surge in floating-point compute (FLOPs) — described as bringing more "FLOP-factories" online. The newsletter contextualises prior inflection points (mid-1990s consumer PC/Internet wave and the mid-2000s end of Dennard scaling), and argues the current AI-driven pace may persist for years before reverting toward the long-term trend. The piece also notes mainstream coverage (Bloomberg, WSJ) and opens with a remembrance of journalist Om Malik.
Google's TPU Fleet Dominates AI Compute Growth
An analysis by Gennaro Cuofano highlights a major structural shift in AI infrastructure: Google’s TPU fleet expanded 11.5× over seven quarters, with quarterly additions accelerating. The report states Google's TPU power draw now exceeds Microsoft’s entire AI compute stack, and that by Q4 2025 Google added more compute in a single quarter than xAI had built in total. These data points indicate a widening infrastructure lead for Google that could cascade into lower per‑token costs, faster model iteration, and a larger operational moat for products and services that depend on large-scale inference and training capacity. The piece frames the compute growth as a pivotal industry trend with broad implications for competition, capability, and deployment timelines across AI-dependent sectors.
