Robert Shiller on TSMC
TSMC’s earnings support its AI spending story, but October’s customer and Texas reports do not yet show what that spending will earn.
TSMC passes part of Shiller’s new-era test on reported business, not just language. CNBC’s quarterly account puts second-quarter 2026 revenue at about $39.45 billion, up 36% from the comparable 2025 quarter, and net income at about $21.9 billion, up 77.4% from that quarter. Bloomberg’s capex account says management raised full-year 2026 guidance to $60–64 billion from $52–56 billion, citing “the AI megatrend.” TSMC closed October 14 at $439.81, compared with its July 22 close of $418.59, per the supplied market data and prior take. The record shows Shiller’s pairing of a rising price and a structural-change story; it cannot show that the price recruited buyers or caused management’s spending decision.
Microsoft gives the story another customer application. The Verge reports that Microsoft’s Maia 300 uses TSMC’s N2P process and is intended to become Microsoft’s primary AI inference system. Reuters reports that AMD’s Lisa Su wants more advanced wafer capacity for 2027 as AMD plans to increase supply, but Reuters reports no TSMC wafer commitment in that item. The record supplies neither Maia wafer volumes nor incremental TSMC margin. CNBC’s July margin account also says management expects overseas fabs to dilute margins for several years. TSMC’s reported demand and planned spending therefore leave Shiller’s feedback-loop question open: the record cannot yet measure the payoff behind the story.
The TEXXR company corpus counts 30 TSMC-tagged articles in July–September 2026, its last complete quarter, against its supplied eight-quarter average of 29.2 articles per quarter. The record also lists October 12 and October 13 entries for the same Verge Maia report. Those entries meet Shiller’s media-amplification test as repeat coverage of one story, not evidence of separate chip orders.
Culpium’s Terafab report says Elon Musk acknowledged TSMC supply discussions. Bloomberg’s later report says Musk ruled out a TSMC operating role. Culpium’s Texas account separately describes meetings between TSMC executives and state officials in the first half of 2026, after intermittent talks for more than a decade. The record cannot turn supply talks, site talks and an excluded operating role into one completed fab. TSMC is scheduled to report earnings October 15; the cited quarterly accounts still lack comparable depreciation and free-cash-flow figures to test cash conversion against higher capex.
