Global Market: TSMC to invest additional $100 billion in Arizona, raises capex on booming AI demand

Taiwan Semiconductor Manufacturing Co. (TSMC), the world's largest contract chipmaker, announced an additional $100 billion investment in Arizona and raised its capital expenditure guidance, underscoring its confidence that artificial intelligence-driven demand will remain robust through the end of the decade.

The company said the fresh investment will be added to its previously announced $165 billion commitment in Arizona, expanding its U.S. manufacturing footprint as global demand for advanced AI chips continues to surge.

TSMC also increased its capital spending outlook for 2026 to $60 billion-$64 billion, up from its earlier forecast of the higher end of $52 billion-$56 billion, signalling stronger confidence in long-term AI infrastructure spending.


According to Reuters, the chipmaker's optimism follows a blockbuster second quarter, with net profit surging 77% year-on-year to a record T$706.6 billion ($22 billion), comfortably beating analysts' expectations of T$632.6 billion. The earnings marked the company's ninth consecutive quarter of double-digit profit growth.

The company also lifted its full-year revenue growth forecast in U.S. dollar terms to slightly above 40% for 2026, compared with its earlier expectation of more than 30%. For the current quarter, TSMC expects revenue between $44.6 billion and $45.8 billion, up sharply from $33.1 billion in the same period last year.

Demand for TSMC's advanced 3-nanometre and 2-nanometre process technologies, along with its advanced chip packaging technology, CoWoS, continues to remain strong as cloud service providers accelerate investments in AI infrastructure.

The company said the additional Arizona investment could include four more facilities, including advanced packaging plants, adding to the eight fabs that are already operational, under construction or planned. The timeline for the new projects will depend on market conditions.

TSMC's aggressive investment plans have reinforced its position as a key barometer for global semiconductor demand. The company manufactures advanced chips for leading technology firms, including Nvidia and Apple, and has emerged as one of the biggest beneficiaries of the AI boom.

The latest investment announcement follows the company's disclosure earlier this week of a 36% increase in second-quarter revenue, which also exceeded market expectations.

The upbeat outlook from TSMC came a day after Dutch semiconductor equipment maker ASML raised its own 2026 sales forecast and announced plans to expand manufacturing capacity, suggesting that supply chain constraints in AI chip production may gradually ease.

Impact on stocks
TSMC's stronger earnings, higher capital spending plans and raised revenue outlook are expected to provide a positive read-through for the global semiconductor sector. Shares of AI-related chipmakers, including Nvidia, as well as semiconductor equipment manufacturers such as ASML, could benefit from renewed confidence in sustained AI infrastructure spending. The outlook is also supportive for companies involved in advanced chip packaging and semiconductor supply chains.

TSMC shares listed in Taipei have climbed 59% so far this year, reflecting strong investor confidence in the company's central role in the global AI semiconductor ecosystem.
