One company makes 73% of the world’s foundry chips
Counterpoint: TSMC held 73% of pure-play foundry revenue for two straight quarters in 2026. Samsung has 7%. SMIC has 5%. Advanced intelligence has a single address, and it is in Hsinchu.

A monopoly that is also a geography
Counterpoint’s 2026 foundry tracker is the print: TSMC took 73% of pure-play foundry revenue for two consecutive quarters, with 2 nm in production and 3 nm still ramping. Samsung Foundry is about 7%. SMIC about 5%. The Magnificent Seven’s intelligence infrastructure, the $1.5 trillion chip year, and the 5× compute slope all pass through a handful of EUV lines in Taiwan. This is more concentrated than oil ever was. It is more concentrated than the Mag7 are in the S&P.
Arizona is a press release. Hsinchu is the node
TSMC’s overseas fabs are real and late. Leading-edge yield still lives where the process engineers live. Pair this with The $1.5 trillion bottleneck and Rare earth choke. Every magazine in this issue keeps finding a single address: refined magnets in China, advanced wafers in Taiwan, interconnection queues in Virginia. Diversification is a project, not a fact. The investing tell is that 73% revenue share on a booming market is pricing power until a customer (Apple, Nvidia) or a state (Washington, Beijing) decides it is a problem.
The long view is a dual-use chokepoint with a queue
You cannot litigate a 2 nm yield. You can wait. Own the scarce layer — TSMC itself, ASML, the HBM that sits next to the wafer — and size the geopolitical tail. Do not own a 2026 ‘foundry renaissance’ in a place that is still on 14 nm and a subsidy.
Investing lens
Horizon 3–8 years · Educational, not advice
73% of the foundry is one firm in one island. Own the scarce node and its toolmakers. Treat everyone else’s foundry slide as an option, not as a 2026 earnings story.
Where the map points
- TSMC, sized as a known concentration
- EUV and process-tool monopoly adjacent (ASML class)
- HBM and advanced packaging that must sit next to the wafer
- Non-TSMC foundry only where a trailing node has a captive customer
What can break it
- A blockade, an earthquake, a water year
- Customer concentration (a handful of AI buyers)
- Intel or Samsung actually catching a node — historically expensive to bet on

Seven names, a third of the S&P
Apple, Microsoft, Nvidia, Amazon, Alphabet, Meta and Tesla were 34% of the S&P 500 in August 2026 — about $24 trillion in one corridor of the market.

China still refines the transition
The IEA’s last minerals outlook was unambiguous: concentration at the refinery rose, not fell. China is the dominant processor of 19 of 20 strategic minerals.
