TSMC's latest report is solid, and numbers like these impress on their own. The harder question is what comes next, because chips have run so far that attention has shifted to the ecosystem around them: power, cooling, and permitting.
Leading-edge chips drive the demand
The plants cannot run any faster. TSMC's N2, its two-nanometer production line, is online and making money. Intel's 18A node has done very well. These sit at the absolute front edge of the technology. About two-thirds of TSMC's revenue comes from the two, three, and five nanometer nodes, which is exactly where AI chips are made. The demand signal is clearly there, and producers are responding, though the market around it stays complicated.
What it says about broader AI demand
Every chip a company like TSMC makes runs on hardware from Applied Materials or ASML. Those machines are very complex, very expensive, and sold in multi-year deals. When ASML traded up in Europe on TSMC's numbers, that made sense: TSMC is its biggest customer, and ASML wants to raise prices too. TSMC also lifted the forward capital it plans to spend on future development. All of that points to demand staying strong. The worry now is execution. After a huge run, the win goes to companies that keep delivering. Pat Gelsinger at Intel keeps talking about execution, and TSMC, which has executed well for years, is the model to copy.
Geography, power, and water
TSMC is lining up with US policy and moving to reduce its dependence on Taiwan, a shift both parties support. It is building in Arizona and has talked about a $100 billion expansion there. That raises real problems: geopolitical tension, environmental strain, Arizona's water shortage, and a data-center moratorium in New York State tied to energy and water use.
Taiwan works because it spent decades building a tight ecosystem around its fabrication plants. Making the chip is only one step. Chips must be packaged, and that needs many advanced materials from many suppliers. The same web of people, skills, and suppliers now has to form around places like Arizona, Sherman in Texas, and the Capital District of New York State. Making a chip here and shipping it halfway around the world for packaging helps no one.
Power decides location. TSMC does not run data centers; companies like AWS do. But everyone is watching which states import most of their power and which have strong base-load power already on the grid. That is the main factor global companies weigh when choosing where to put their money in the US. A few years back there were also culture clashes and worker troubles for TSMC in places like Phoenix.
Capital spending signals confidence
Capital spending is the strongest measure of how confident management really is, and this report reads as very confident. Many deep-ecosystem companies, Micron among them, are pouring incoming cash back into future capacity. TSMC raised its capital spending outlook by $60 billion. Companies watch demand for their products very closely, and TSMC sees no drop, not even a small one. Demand should keep going, especially at the advanced nodes. The two-nanometer node is executing beautifully, but it is hard work. This week brought rumors that Intel is doing very well on its 18A node. Keeping the technology moving forward will take a lot of money.
Sharing the load and the packaging bottleneck
Some customers are now looking for alternatives, such as Samsung's foundry, because of capacity limits at TSMC. There has to be room to spread the work. The lesson of 2020 to 2022 was that a single supplier is dangerous, so even firms happy with TSMC, Samsung, or SK Hynix want more than one channel. The catch: the closer you get to the leading edge, the fewer credible suppliers remain. So a chip buyer has to sort out which products truly need the absolute leading edge and which can use more mature nodes at 5 to 7 nanometers and above 7 nanometers, where plenty of capacity exists.
The deeper limit came straight from management on the morning call: packaging is completely maxed out. You can build all the chips you want, but they mean nothing until you can fold them into products that ship and sell. Intel has done great with advanced packaging, and TSMC is seeing strength too, yet everyone is now fully booked on what to do with the chip after it is made. On any report from here, the number to watch is how packaging is doing.
