The 30,000-ft map of AI infrastructure stocks across nine layers — compute, memory, HBM packaging, lithography, photonics, networking, cooling, power, and neocloud operators — with the publicly-listed leaders in each layer and why a focused stack beats the BOTZ / AIQ / ROBO / IRBO ETFs.

There's no single answer — there are nine layers, each with its own bottleneck depth. Default megacap exposures: $NVDA (compute), $MU (memory), $ASML and $TSM (fab tools), $AVGO (custom ASIC). Asymmetric mid-caps: $ALAB and $CRDO in retimers, $VRT in cooling, $GEV in power, $COHR in photonics, $BESIY in hybrid bonders, $CRWV in neoclouds. A diversified portfolio across the nine layers is the standard institutional approach.
"AI stocks" lumps software (Microsoft, Salesforce, Palantir), hyperscalers, and infrastructure together. AI infrastructure is specifically the physical buildout — silicon, memory, packaging, networking, cooling, power, and the data centers that house them. It's what monetises hyperscaler capex regardless of which AI application wins.
No — and that's the central insight here. $NVDA captures the compute layer; the other 8 layers have their own publicly-listed leaders. $MU, $ASML, $AVGO, $COHR, $VRT, $GEV, and $CRWV are all materially exposed to the same capex super-cycle without taking single-architecture risk on Blackwell vs Rubin vs MI400.
A genuine demand pause from one or more hyperscalers. A Microsoft, Google, or Meta capex cut would re-price the entire stack. Mitigants: (a) sovereign demand layering on top, (b) 12-24 month booking visibility, (c) bottleneck depth — when you cannot get hybrid bonders for 18 months, pricing power holds even if one buyer pauses.
Macroplane organises the universe into the nine baskets above plus the Data Center Buildout trend and the Silicon Photonics & Optical Interconnects trend. Each company page links to live financials, news, and the supplier/buyer relationship map — so when $NVDA announces a Rubin design win at $AVGO, you can trace the impact to packaging tool orders at $BESIY and laser shipments at $COHR.
