🍠 TSMC’s U.S. footprint is growing—but where does packaging fit? - 2026.11.03

Hi, it’s Sweet Potato. Today, let’s start with how TSMC is moving on U.S. soil. 🍠 The stock closed at $398.67 on November 2, down -1.84% from the previous day, and was at $406.13(-5.95%) on October 30. News of U.S. investment is layered on top of that trend.

🍠 The U.S. footprint is growing

The Electronic Times covered TSMC’s continued investment in Texas, noting that a competitive dynamic is emerging in the same region as Samsung ^[1]. Bloomberg reported that TSMC’s campus development is fueling a real estate boom in the suburbs of Phoenix ^[2]. In other words, a single factory can change land prices and the feel of a neighborhood. However, figures for the scale of investment differ in the headlines, so I’ll leave out the exact amount here.

A Taipei Times column viewed TSMC’s overseas expansion as a necessity rather than a choice ^[3]. That’s the columnist’s assessment, not something the company has said. So I’ll treat it as interpretation, too.

⚖️ But there are still conflicting views

NewsPim presented an analysis suggesting that if investment in AI infrastructure declines, packaging companies could be hit before TSMC ^[4]. That, too, is an assumption made by the analyst. And that raises a question: if packaging is the first to come under pressure, where does the currently discussed CoWoS pricing trend fit in?

TradingView’s weekly recap covered both third-quarter revenue growth and CoWoS price increases ^[5]. Rising revenue and higher packaging prices are both faces of demand. But when prices rise, the question of who bears the cost comes along with them. On this point, bullish and more cautious interpretations could diverge sharply.

🤝 The 1-nanometer news, the stock, and the variables still in play

Wccftech reported that TSMC’s 1-nanometer manufacturing site appears to have been revealed by Taiwan’s minister during a discussion that included robots ^[6]. However, the report is based mainly on headline information, and the site and schedule have not yet been confirmed. It’s best to treat this cautiously, like a rumor. Benzinga also covered TSMC’s stock movement on Monday, but the specific reasons need to be checked against the original article ^[7]. So I’ll use the stock price only as a supporting indicator for interpretation.

Here’s how I’d sum up the four perspectives. Bullish and bearish scenarios are both on the table, and I won’t claim yet that either one is right. My personal view is closer to the idea that U.S. expansion and packaging bottlenecks are connected. Still, I want to leave room for other views on how strong that connection really is.

How will expanded U.S. investment intersect with packaging demand, and will the 1-nanometer news be confirmed as an actual timeline? Those are the two things I’m most curious about right now. Which one catches your eye first? 🍠
