TSMC Is Pouring $100 Billion More Into Its Arizona Plant to Keep Up With Strong US Customer Demand

Taiwan Semiconductor Manufacturing Co. Ltd. (NYSE:TSM) will pour an extra $100 billion into its Arizona facilities to cater to the burgeoning customer demand.

On Thursday, the chipmaker’s Chief Executive Officer C.C. Wei told an earnings conference that the additional funding is targeted at building several semiconductor logic wafer fabs for two-nanometer mass production technologies.

TSMC’s total investment in Arizona will now sum up to a whopping $265 billion.

Wei underscored the company’s dedication to fulfilling the escalating demand, stating, “This is to build several or more semiconductor logical wafer fabs for two-nanometer MP [mass production] technologies, as well as advanced packaging fabs to support the strong multi-year demand from our leading U.S. customers.”

The news comes as TSMC posted record second-quarter results, with net income surging 77.4% year over year to NT$706.56 billion ($22 billion), beating analyst estimates and marking its fifth consecutive record quarterly profit. Revenue climbed 36% to NT$1.27 trillion ($39.45 billion), also exceeding expectations.

TSMC Accelerates 2nm Expansion

The move comes in the wake of a broad trade agreement between Taiwan and the Trump administration, which paved the way for TSMC’s expansion. The company had previously acquired more land in Arizona and fast-tracked fabs in response to the new U.S.-Taiwan trade agreement that reduced tariffs on Taiwanese goods to 15% and included $250 billion in planned Taiwanese investment in the U.S.

Furthermore, TSMC’s decision to boost its investment aligns with its strategy to ramp up next-generation chip production and global capacity. The company had earlier announced a 70% increase in 2nm production to power the AI future. This move was also backed by billionaire investor Lewis Sanders, founder of Sanders Capital, who owns approximately 28.1 million TSMC shares valued at about $9.5 billion, making the chipmaker the firm’s largest holding.

On Monday, TSMC reported a 67.9% year-over-year increase in June revenue, lifting its first-half 2026 revenue to NT$2.4 trillion ($75 billion), up 35.6% from a year earlier.
