About AI Capex
AI Capex is a research and trading platform focused on the AI infrastructure supercycle — tracking where the capital is flowing, what it builds, and which companies across the supply chain are positioned to benefit.
We cover the full stack: hyperscaler capex commitments, AI chips and memory, advanced packaging, optical networking, power and cooling, cloud infrastructure, and the software platforms that run on top of it all.
What's on the site
Capex Signal
A weekly research note on AI infrastructure spending and what it means for semiconductors, cloud, and adjacent markets. Each issue breaks down earnings calls, capex guidance, and supply chain signals — with a clear “so what” for investors. Free articles are publicly available; the deeper analysis layer is for subscribers.

Why this is different
Most market commentary chases headlines. AI Capex starts from a different premise:
“Follow the capital. It shows up in supply chains before it shows up in stock prices.”
We track hyperscaler capex commitments, read earnings transcripts for constraint language, and trace the signal from infrastructure spend down to the components, packaging, and software that benefit most. The AI Trading Assistant puts that context directly into a conversational interface with live prices — so you can ask a question and get a grounded, specific answer instead of a generic one.
