TSMC's $40bn quarter triggers fresh AI stock selloff
TSMC's record $40 billion quarter triggered a 4% share price drop as surging capital expenditure forecasts signalled an end to blind faith in AI spending for global investors.
Taiwan Semiconductor Manufacturing Company reported second-quarter revenue exceeding $40 billion, a 36% year-on-year increase, alongside a 77% surge in net income. By historical standards, the results should have been a triumph. Instead, its shares fell 4%, dragging the Nasdaq 100 down 1.4% on Thursday and compounding losses from the previous session.
The selloff was driven not by the earnings, but by the staggering cost of generating them. TSMC raised its 2026 capital expenditure forecast to between $60 billion and $64 billion, a sharp increase from its previous guidance of $52 billion to $56 billion. For investors tracking the bottom line, this steep spending trajectory has become a liability rather than a sign of future dominance.
The reaction reflects a broader exhaustion across global tech markets. The semiconductor index has now fallen nearly 19% from its all-time highs. Market concentration in AI stocks currently exceeds levels seen during the dot-com bubble, with valuations relying on revenue growth that has not yet materialised at the scale share prices imply.
TSMC is the definitive bellwether because it manufactures the advanced chips for Nvidia, Apple, and nearly every other major firm driving the AI boom. When a record quarter from this central supplier triggers a market selloff, it indicates that investors are demanding proof of returns rather than accepting promises of future disruption.
For European portfolio managers heavily exposed to US tech equities, the implications are immediate. Good financial results are no longer sufficient to sustain confidence. The AI industry has spent an estimated $1.6 trillion on development over the past decade without delivering proportionate returns. Recent warnings from the BIS, Man Group, and Goldman Sachs about an unsustainable spending cycle are now actively being priced into equities.
TSMC will likely continue posting record revenue as long as its clients keep ordering. The structural question now facing global markets is whether those purchasing the chips can generate enough actual return to justify a collective trillion-dollar bet. If they cannot, the current capital expenditure cycle is merely building expensive infrastructure for demand that arrives late, scales down, or fails to appear entirely.
