01What it rests on, and what rests on it
Depends on
- Leading-edge foundry capacity
“We utilize foundries, such as Taiwan Semiconductor Manufacturing Company Limited, or TSMC, and Samsung Electronics Co., Ltd., or Samsung, to produce our semiconductor wafers.”
sec.gov · primary source · The filing names the foundries, not the node.
- High-bandwidth memory stacking yield
“We purchase memory from SK Hynix Inc., Micron Technology, Inc., and Samsung.”
sec.gov · primary source · Memory in general; these three are the recorded HBM makers.
- Advanced packaging capacity
“We utilize CoWoS technology for semiconductor packaging.”

04Ways to take part
Not investment advice. This says how the public can reach a company — a job, its shares, its products — not whether anyone should. It takes no account of anyone’s circumstances, and a company holding a chokepoint is not a reason to own it. What this is not
- Work there
- It publishes its roles on its own careers page.Official careers page ↗
- Own part of it
- Its shares trade publicly as NVDA US, bought and sold through a broker that reaches that exchange.NVDA US listing record ↗Its SEC filings
- Buy from it

A loop is one design, build and measure turn. Severity is a dated judgement on a 0–12 scale, not a measurement, and the judgements are not added together — the figure shown is the worst single one.
