The world's most important chipmaker is doubling down on the United States. Taiwan Semiconductor Manufacturing Company, or TSMC, said it will add $100 billion to its U.S. spending plans, according to The New York Times and the BBC, with the money earmarked to expand production in Arizona.

The BBC and AZ Family report the fresh commitment could bring roughly four new chip factories to the state. MacDailyNews framed the move as a Trump administration win, describing a record total TSMC investment of $265 billion and a plan to reach 12 U.S. facilities — though the higher figures appear only in that single source and should be read with caution.

The expansion lands alongside blockbuster earnings. Multiple outlets, including Investor's Business Daily and reports carried by eciks.org, say TSMC beat second-quarter targets and posted a record profit, with net income surging 77% as demand for leading-edge AI chips stayed strong. According to finance.biggo.com, the company lifted its revenue growth outlook to over 40% and plans to boost 2026 capital spending by nearly 10%, calling AI demand "robust through 2030." The Next Platform notes AI chips now drive around a third of TSMC's revenue.

The upbeat forecast rippled across the sector. Invezz reported that memory-chip stocks including Micron and SK Hynix fell as TSMC's outlook sparked a selloff, even as the broader chip group has recovered from early-July volatility.

Why it matters: TSMC makes the advanced processors behind nearly every major AI system, so where it builds factories and how much it spends shapes both the pace of the AI boom and where the critical technology of the next decade gets manufactured.
