AI Infrastructure 101

The Investor's Map to the AI Build-Out

No other source maps the AI infrastructure supply chain from the investor's perspective. Each entry explains what it is, why it matters for portfolios, who benefits, and how Closelook systematically tracks it.

This is not a generic technology glossary. Every entry here passes the Closelook Proprietary Test: it either describes a concept unique to Closelook, or offers an investment angle that no other source provides. If Investopedia covers it better, it belongs in the Glossary, not here.
