Bridging the gap between business and the world’s most important industry.

SemiAnalysis is an independent research and analysis firm covering the semiconductor and AI supply chain end to end: capital equipment, fabrication, foundries, chip design, networking, datacenters, and the models that run on top. Our work is read by the executives, engineers, and investors who build and fund the industry.

Our story

The gap between what companies say and what the supply chain shows is where our work lives.

SemiAnalysis exists to close the information gap around the world’s most important industry. Semiconductor and AI decisions now move hundreds of billions of dollars a year, and the public record behind them is thin. We fill that gap with primary research: supply chain tracking, fab and datacenter monitoring, and time on conference floors, not vendor guidance retold.

The work spans a newsletter read by more than 180,000 subscribers, institutional data models that track the supply chain SKU by SKU, and consulting for organizations working a specific question. Each feeds the others: what we learn in the field sharpens the models, and what the models surface directs the next round of field work.

Product first
Technology and trends are analyzed from the product outward, then mapped to the companies around them. No firm is viewed in isolation.
In the field
The team attends more than 40 industry conferences a year and engages the stack at every level of abstraction, from lithography physics to model training runs.
The flywheel
Semiconductors and AI form one intricate supply chain. Context from upstream makes the downstream call sharper, so findings loop back into every adjacent segment we cover.

One supply chain, covered at every layer.

Capital equipment & materials

Lithography, deposition, etch, metrology, and the materials that feed them

Fabrication & packaging

Process flows, yields, and 2.5D and 3D advanced packaging

Foundries & process economics

Process nodes, wafer yields, and costs across the foundry landscape

Chip design & VLSI

Architectures, IP, and the design choices that set performance and cost

Networking & optics

Switches, transceivers, co-packaged optics, and cluster fabrics

Datacenters & systems

Server architecture, power, cooling, and the datacenter buildout

Software & EDA

The toolchains and software layers the hardware depends on

AI training & inference

Model frameworks, infrastructure, performance, and cost

Plus the adjacent segments the supply chain pulls in as it moves.

What the industry says.

Analysts and engineers covering the semiconductor and AI supply chain end to end, from fab equipment to the models that run on the silicon. A lot of the job happens out in the industry: fabs, data centers, conferences, and earnings season. The photos come from the time in between.
