It came alongside record quarterly revenue of $40.2 billion and a sharply higher spending plan, as demand for AI chips shows no sign of cooling. Taiwan Semiconductor Manufacturing Co. used its second-quarter earnings to make clear that the artificial-intelligence building boom is still accelerating. The company, which makes the most advanced chips for customers including Nvidia, Apple and AMD, said it [plans to invest a further $100 billion in the United States, on top of an existing $165 billion commitment to Arizona, according to Nikkei Asia](https://asia.nikkei.com/business/tech/semiconductors/tsmc-plans-further-100bn-us-investment-to-feed-ai-demand). If carried through, that would lift TSMC's planned US spending toward roughly a quarter-trillion dollars, though the company did not put a combined figure on it or set a timeline for the new phase. ## A record quarter behind the plan The spending pledge came with numbers to back the confidence. TSMC reported [second-quarter revenue of $40.2 billion, a record, with a gross margin of 67.7%](https://investor.tsmc.com/english/quarterly-results/2026/q2), and guided current-quarter revenue higher still. The company also said it now expects full-year revenue to grow more than 40% in US-dollar terms, [per Nikkei Asia](https://asia.nikkei.com/business/tech/semiconductors/tsmc-plans-further-100bn-us-investment-to-feed-ai-demand), a pace that reflects how much of the AI supply chain runs through its factories. As a "foundry," TSMC does not design chips of its own; it manufactures them to order for others. That makes it a useful gauge of the whole industry: when data-center operators and chip designers are racing to add capacity, the orders land at TSMC first. The record quarter suggests that demand from the companies building AI infrastructure has not yet cooled, a question that has weighed on investors worried the spending cycle could turn. ## Capex raised again TSMC also lifted its capital-expenditure plan for the year to about $60 billion to $64 billion, up from a prior range of roughly $52 billion to $56 billion. Capital expenditure is the money a company spends on long-lived assets: here, the enormously expensive machines and buildings needed to make chips at the cutting edge. A single advanced fabrication plant, or "fab," can cost well over $20 billion, and the tools that etch circuits measured in billionths of a meter are among the most expensive equipment on earth. The company said the bulk of that spending targets its most advanced processes, the 3-nanometer and 2-nanometer technologies used for AI accelerators and high-end phones, with the rest going to advanced "packaging" and plants outside Taiwan. Packaging, the step that stitches multiple chips together into one high-performance part, has become a bottleneck in the AI supply chain, with demand running well ahead of capacity. ## Why build in Arizona TSMC's existing $165 billion Arizona plan was itself built up in stages: an [initial $65 billion commitment, expanded by a further $100 billion announced in early 2025](https://pr.tsmc.com/english/news/3210). Its first Arizona fab began producing 4-nanometer chips in early 2025, the first cutting-edge wafers TSMC has made on US soil. Manufacturing in Arizona costs more than in Taiwan, where labor and construction are cheaper and the company's expertise is concentrated. But building in the US helps TSMC's customers reduce their exposure to tariffs and to the geopolitical risk of relying on Taiwan, an island China claims, for the world's most advanced chips. Washington has pushed hard, with subsidies and political pressure, to bring more semiconductor production onshore. The latest $100 billion pledge is a sign that the incentives, and the demand, are strong enough for TSMC to keep committing. ## The caveats The scale is striking, but the details are thin. TSMC did not specify what the new $100 billion will build, over what period, or how it splits between fabs and packaging. Large multi-year investment pledges are also easier to announce than to complete on schedule, and depend on demand holding up. The core message, though, is hard to miss: the company at the center of the AI hardware boom is betting tens of billions more that the boom is not over. Boursel will track whether the spending translates into capacity on the ground. ## Sources - [TSMC plans further $100bn US investment to feed AI demand](https://asia.nikkei.com/business/tech/semiconductors/tsmc-plans-further-100bn-us-investment-to-feed-ai-demand) - [TSMC Intends to Expand Its Investment in the United States to US$165 Billion](https://pr.tsmc.com/english/news/3210) - [TSMC 2026 Second Quarter Results](https://investor.tsmc.com/english/quarterly-results/2026/q2)
