Chipmakers report record earnings, but stocks decline amid skepticism over AI spending

TSMC just posted the best quarter in its history. The stock dropped 4%.

Taiwan Semiconductor Manufacturing Co. reported Q2 2026 revenue of $40.2 billion, a 36% jump year-over-year, driven by insatiable demand for AI chips. Net profit hit NT$706.56 billion, or roughly $21.99 billion, surging 77.4% compared to the same period last year. The company even raised its full-year revenue growth outlook to slightly above 40%.

The capex problem

TSMC simultaneously hiked its 2026 capital expenditure guidance to between $60 billion and $64 billion. That’s up from a previous estimate of $52 billion to $56 billion, an increase of roughly $8 billion at the midpoint.

In premarket trading following the earnings release on July 16, TSMC shares fell approximately 4%. NVIDIA dropped 1.3%, AMD slid 2.7%, Intel fell 1.9%, and Micron declined 2.4%.

Bitcoin mining stocks caught in the crossfire

The semiconductor selloff spilled directly into crypto-adjacent equities. IREN, Cipher Mining (CIFR), and TeraWulf (WULF) all dropped between 4% and 5% in the session following TSMC’s report.

The AI spending sustainability question

TSMC’s advanced nodes, including its 2nm, 3nm, and 5nm processes, are the backbone of virtually every major AI chip on the market. NVIDIA’s GPUs, AMD’s accelerators, and the custom silicon being designed by hyperscalers like Google, Amazon, and Microsoft all flow through TSMC’s fabs. The company is telling the market that maintaining that position requires spending $60 billion to $64 billion this year alone.

A 77% profit increase suggests the investment is paying off handsomely right now. However, the semiconductor industry overbuilt during the pandemic era, when chip shortages gave way to inventory gluts in 2022. If AI spending plateaus, TSMC could find itself with expensive excess capacity.

July 2026 appears to mark a meaningful inflection point in how investors are pricing AI-related risk.

What this means for crypto investors

The 4-5% decline in names like IREN, CIFR, and WULF followed semiconductor concerns directly tied to TSMC’s capex increase. Many Bitcoin miners have been repositioning themselves as AI infrastructure plays, pitching their data centers as dual-purpose facilities. That narrative becomes harder to sell if the market is questioning whether AI infrastructure spending is sustainable. Traders should watch TSMC’s capex trajectory and hyperscaler spending commitments in coming quarters as leading indicators of whether this skepticism deepens or fades.
