⚠ Competition, Cyclicality & Capital IntensityHigh threat

Beneath the singular geopolitical risk lie the more ordinary but ever-present hazards of TSMC's business: subsidized competitors trying to close the gap, the violent cyclicality of the semiconductor industry, the crushing and rising capital intensity, and a valuation now lifted by the AI boom. Each is manageable, and none has dented the moat, but together they frame the realistic risks an investor takes on alongside the geopolitical one.

On competition: while TSMC's lead is currently widening, it faces two rivals — Samsung and Intel — backed by their own vast resources and, increasingly, by government subsidies aimed explicitly at breaking TSMC's dominance for reasons of national security. The rivals are far behind today, but the world's most powerful states are funding the effort to build credible alternatives, and TSMC's own customers want a second source. On cyclicality and capital: the industry booms and busts, TSMC's revenue fell as recently as 2023¹, and the company is now committing sixty billion dollars and more a year — into an AI-driven build-out — with the ever-present risk of building expensive capacity into a peak that then recedes. The capital intensity is a real, rising claim on cash and a permanent exposure to getting the cycle's timing wrong.

And on valuation: TSMC's shares have risen substantially in the AI boom to around twenty-seven times earnings² — richly valued by the company's own history, though still well below ASML, a gap that reflects the premium the market withholds for the Taiwan risk (a de-rated Nvidia now trades slightly lower). The earnings the multiple is applied to are elevated by the AI cycle, so a downturn would compress both earnings and multiple together, as with any cyclical bought near its peak. The moat is not in question — TSMC will capture essentially all of whatever leading-edge demand exists, through every cycle, for as far ahead as anyone can see. What is in question is whether the AI boom that has lifted the recent numbers proves as durable as the price assumes, whether the subsidized rivals ever become credible, and whether the rising tide of capital spending earns its return. These are the ordinary risks of a wonderful but cyclical, capital-hungry business at the center of a boom — real, but second-order beside the shadow of the Taiwan Strait.
