TSMC's Record Quarter Collides With a Chip-Sector Selloff as Wei Draws a Line on Terafab

TSMC shares slipped 2.5% on the day even as the foundry giant's third-quarter 2026 results landed well ahead of profit expectations — a divergence that says more about the mood across the chip sector than about the company's own performance. The decline was tied to broader selling pressure on semiconductor names, not to any earnings miss.

Inflation Fears Weigh on the Sector

Media reports on Thursday flagged unexpectedly hot US inflation data as the drag, feeding worries about interest-rate hikes and the cost of building out artificial intelligence infrastructure. A price-target upgrade from Barclays, also reported yesterday, was not enough to offset that backdrop.

The operating picture and the market reaction have thus pulled in opposite directions. TSMC reported third-quarter 2026 revenue of NT$1,494.24 billion and net profit of NT$763.06 billion, beating earnings estimates. Revenue climbed 50.9% from the year-earlier quarter, while net profit rose 68.7% — growth in the bottom line outpacing the top line.

Those figures offer a counterweight to concerns about financing the AI buildout, though they do not erase the rate risks weighing on technology investors, nor the question of what future investment will cost.

Barclays Lifts Its Target

Barclays raised its price target to $670 from $665, according to media reports, while keeping its "overweight" rating. No fuller rationale was disclosed, but the direction of the analyst move was positive — a counterpoint to the weak share-price performance. An upgrade is not proof that market-wide pressures have been fully digested; analyst views and short-term investor risk appetite can diverge.

A Condition for Terafab

On the expansion front, TSMC is tying any possible collaboration with Elon Musk's Terafab project to one clear demand: the company wants to run the chip production itself. CEO C.C. Wei said today that TSMC is negotiating with the project on that basis, according to media reports. "The fab has to be operated by TSMC," Wei was quoted as saying. Musk had previously stated that Terafab would be operated entirely by his company — a fundamental difference in how the two sides publicly describe the arrangement. No concrete partnership terms have been disclosed.

No agreed collaboration can be inferred from the talks, though TSMC's position is unambiguous: any partnership should leave operational control of manufacturing with the company. The negotiations come amid persistently strong demand. Management sees no cooling in the AI business, and demand for chips from advanced process nodes continues to outstrip available capacity. Additional plants would address an existing bottleneck; the terms under which they run remain under negotiation.

Arizona Offers a Concrete Timeline

TSMC's own buildout in Arizona is further along. Wei said Thursday that construction of the second fab is complete, with equipment installation under way. Volume production is slated for the third quarter of 2027 — slightly earlier than previously planned. The second plant will make chips on 3nm technology. TSMC has also begun construction of a fourth Arizona fab and a facility for advanced chip packaging. A further US expansion, including Texas, is under review; no decision has been announced.

Reuters reported that Wei said the company has sent teams to assess expansion options in Texas, and that TSMC is talking with a customer about possible use of capacity tied to that customer's Terafab project. No final investment or agreement has been announced — a distinction that matters, since the talks open a possible expansion avenue without representing committed capacity.

Needham Backs the Capacity Buildout

Needham reaffirmed its buy rating today and lifted its price target to $560 from $530, pointing to TSMC's expansion plans and management's described additional growth potential in AI accelerators. The plans include four new fabs for the N3 process: two in Taiwan and one each in the US and Japan, spreading the buildout across multiple locations.

For investors, the question extends beyond partnership headlines. What counts are credible production plans and the terms on which additional capacity comes online. Arizona provides a concrete date to anchor that; on Terafab, TSMC's demand for operational control is, for now, a negotiating stance rather than a signed contract.
