TSMC, the world's largest chip manufacturer, reported strong quarterly earnings and announced a $100 billion（約16兆円） expansion of its Arizona manufacturing footprint to include advanced packaging capabilities. CEO C.C.
Wei highlighted very strong demand signals from cloud customers, suggesting sustained momentum in AI chip spending rather than a temporary surge.
The expansion and demand outlook are positive signals for Nvidia, TSMC's major customer, which currently trades at a relatively low valuation despite prior investor concerns about slowing growth.
What happened
TSMC reported second-quarter revenue of more than $40 billion（約6.4兆円） (up 33%) and earnings per share of $4.31 (up 77%), and announced a $100 billion（約16兆円） increase in its Arizona manufacturing investment, bringing total U.S. investment to $265 billion（約42兆円）. The company also highlighted strong demand signals from cloud customers.
Why it matters
TSMC manufactures chips for Nvidia and other market leaders, giving it a direct view of chip demand trends. CEO C.C. Wei reported that signals from customers and their customers—mainly cloud providers—are "very strong," suggesting sustained demand for AI chips rather than a temporary spending spike. The expanded U.S. advanced packaging capabilities could save customers like Nvidia time and money by eliminating the need to ship chips to Taiwan for finishing steps.
What to watch
TSMC forecasts third-quarter revenue in the range of $44.6 billion（約7.1兆円） to $45.8 billion（約7.3兆円）. Nvidia trades at 23× forward earnings, which the article characterizes as a bargain valuation amid concerns about whether the company's growth days are behind it.

TSMC's earnings beat and forward guidance arrive at a moment when investors have grown anxious about whether the artificial intelligence boom can sustain Nvidia's exceptional growth trajectory. The semiconductor manufacturing giant's comments on demand are particularly credible because TSMC maintains direct relationships with the chip designers—including Nvidia—who are its customers, and those designers have visibility into cloud providers' future needs. The fact that strong signals are coming not just from chip manufacturers but from the cloud companies that are their end customers suggests the spending cycle has structural foundations rather than being purely speculative.
The $100 billion（約16兆円） expansion of U.S. advanced packaging capacity addresses a specific operational pain point: historically, chips have been designed and partially manufactured in the U.S. but sent to Taiwan for the final, expertise-intensive packaging steps. Eliminating that trans-Pacific journey for Nvidia and other customers could materially reduce lead times and logistics costs at a moment when chip availability is a critical business constraint. For investors worried that Nvidia's valuation no longer reflects future growth, TSMC's demand commentary and investment plan offer reassurance that the infrastructure spending cycle remains robust.
