TL;DRTSMC posted record $40B Q2 revenue but stock fell 4% after it raised capex to $60-64B. Nasdaq 100 dropped 1.4%. Good news is no longer enough for AI stocks.
TSMC posted record second-quarter revenue of over $40 billion, up 36% year on year, with net income rising 77%. The result should have been a triumph. Instead, shares fell 4%, dragging the Nasdaq 100 down 1.4% on Thursday and compounding losses from the day before.
The problem was not the earnings but the spending. TSMC raised its 2026 capital expenditure forecast to $60-64 billion, up from $52-56 billion. Investors are no longer willing to take rising AI infrastructure spending on faith. Good news is not enough to sustain confidence when the industry has spent nearly $1.6 trillion on AI development over the past decade without yet justifying it through proportionate returns.
The semiconductor index has fallen nearly 19% from its all-time highs. Market concentration already exceeds dot-com levels, with AI stock valuations predicated on revenue growth that has not fully materialised at the scale prices imply. TSMC is the bellwether: it manufactures chips for Nvidia, Apple, and nearly every other company driving the AI boom. When its record quarter triggers a selloff, the signal is that investors want proof, not promises.
