AI Infrastructure Economics

AI infrastructure economics covers how compute, chips, cloud capacity, energy, networking, and inference efficiency shape the cost and availability of AI systems.

Key points

TechCrunch reports that AWS is in talks to sell custom AI chips directly to other data centers, which would move Amazon closer to the hardware supply side of AI infrastructure ^[src-140].
This connects to inference economics because hardware supply, chip pricing, and cloud-provider strategy influence what AI products are affordable to build and operate ^[src-140].
Track this alongside local AI hardware, model-fleet routing, and provider cost shifts.
DX Today reports that TSMC added $100 billion to its US investment commitment and lifted 2026 capital-spending guidance to as much as $64 billion, framing foundry capacity as a multiyear AI-demand signal ^[src-220].
The investment direction is corroborated by reporting on TSMC's earnings announcement, but facility counts and timing should remain attributed until the company's detailed plan is captured directly ^[src-220].

Robin Cartier perspective

This page is part of Robin Cartier's working AI knowledge graph: a practical research layer for production AI, recommendation systems, experimentation, GEO, and agentic web readiness.

The useful next step is to connect this concept back to applied product leadership and operating models.
