TL;DR
TSMC 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.
The shift in sentiment is consistent with what the BIS, Man Group, and Goldman Sachs have been warning about for weeks. The AI bubble did not pop, but it sent the bill, and investors are now reading it. TSMC will keep posting record revenue as long as AI spending continues. The question is whether the companies buying its chips can generate enough return to justify the trillion-dollar collective bet, or whether the capex cycle is building infrastructure for demand that arrives later, smaller, or not at all.
