Shares of Taiwan Semiconductor slid roughly 3.5% today even as the world's most important chipmaker reported a quarter that crushed expectations. The disconnect tells you everything: Wall Street is less worried about whether TSMC can sell chips, and more worried about how much it costs to keep making them.
A Blowout Quarter That Still Spooked Investors
TSMC posted record net income of NT$706.56 billion (~$22.35 billion), up 77.4% year-over-year, on revenue of NT$1.27 trillion ($40.2 billion), a 36% increase.
The results topped Wall Street estimates — analysts had expected net income of NT$632.64 billion. Yet shares fell approximately 4% amid concerns over increased capital expenditures and margin pressures. The message: beating profit targets isn't enough when spending plans balloon simultaneously.
The $265 Billion Bet on Arizona
TSMC plans to invest another $100 billion to expand its Arizona manufacturing campus, bringing its planned U.S. investment to $265 billion.
The expansion will add at least four new fabrication plants and two advanced packaging facilities; when fully built out, TSMC could operate up to ten factories on U.S. soil. This spending is partly strategic, partly political — the commitment follows the U.S.-Taiwan trade agreement that cut tariffs on Taiwanese goods to 15% in exchange for $250 billion in planned Taiwanese investment. But the Arizona expansion has faced construction delays and cultural friction, and scaling to ten factories is an enormous operational undertaking with real execution risk.
Spending Is Surging Faster Than Revenue
TSMC raised its 2026 capital expenditure budget to $60–$64 billion, up from a prior $52–$56 billion — a roughly 14% jump in a single quarter. The company also raised its full-year revenue growth outlook from over 30% to slightly above 40% , but higher factory costs in Arizona eat into the fat margins that justify TSMC's premium valuation. Gross margin was 67.7% this quarter , yet Q3 guidance of 65%–67% hints at gradual compression as overseas plants ramp.
AI Demand Is Real, but Concentration Is a Risk
High-performance computing — the segment covering AI accelerators and data-center processors — generated 66% of Q2 revenue, up from 60% a year ago. That dependence is a double-edged sword: the top 10 customers represent 85% of accounts receivable, so any pullback by major cloud-computing buyers would hit hard. For now, demand is insatiable. The question shareholders must answer is whether $265 billion in concrete and equipment will deliver returns to match.
