Neoclouds

Purpose-built GPU clouds — born for AI, not retrofitted. What is a neocloud?

Hyperscalers

The general-purpose giants, where AI is one workload among hundreds. The contrast that makes neoclouds make sense.

AI Chips

The silicon the buildout runs on. NVDA, AMD, MU and SK Hynix are queued for full deep dives.

Prices and caps verified Sep 19, 2026. NVIDIA is the supplier and, in some cases, an investor in its own customers; that circularity is covered on the explainer page.

Memory & Storage

Every compute cycle hits the memory wall first. The supply side of the same buildout.

SK Hynix and Kioxia are not US-listed. Prices and caps verified Sep 19, 2026. Kioxia has no figure because it is not US-listed and we have not verified one. Holdings and weights are on the DRAM page.

Miners Pivoting to AI

Bitcoin miners converting power and sites into AI hosting. High risk, high optionality — and the leases are now real.

Every name in this section is currently loss-making on a GAAP basis — mostly digital-asset marks. CIFR, RIOT and CLSK have signed large AI leases; MARA and Keel hold sites and power without tenants.

ETFs

One-ticket exposure to the buildout. Stocks and ETFs are never mixed in the tables above.

NRAM launched on Sep 10, 2026 and is new enough that we are watching rather than covering it. NCLD figures are as reported at launch, not current. NCLD’s concentration and the alternatives are compared on the neocloud ETF page.
