TSMC Just Had Its Best Quarter Yet. The AI Boom Is Raising The Bar Even Higher.

Taiwan Semiconductor Manufacturing Co. (TSMC) reported its strongest quarter on record on Thursday, posting a 77.4% increase in second-quarter profit as demand for advanced semiconductors used in artificial intelligence applications continued to lift the world's largest contract chipmaker.

Net income for the April-to-June period rose to NT$706.56 billion ($22 billion), while revenue climbed to NT$1.27 trillion ($39.45 billion), both exceeding analyst estimates and marking the fifth consecutive quarter of record earnings. The company also forecast third-quarter revenue between $44.6 billion and $45.8 billion.

The company said it will invest an additional $100 billion in Arizona, bringing its total planned investment in the state to $265 billion. Chairman and Chief Executive C.C. Wei said the funding will support the construction of additional semiconductor fabrication plants and advanced packaging facilities for 2-nanometer chip production to meet demand from U.S. customers. CNBC reported that the expansion is aimed at supporting "strong multi-year demand" from leading American clients.

TSMC also increased its projected capital spending for the year to between $60 billion and $64 billion, up from prior guidance, while Chief Financial Officer Wendell Huang said the company continues to invest heavily to support customer growth, according to CNBC.

The Taiwanese chipmaker's performance has been closely tied to the continued buildout of AI systems by major technology companies. TSMC manufactures chips for several of the industry's largest players, including Nvidia, Apple and Broadcom. High-performance computing, a category that includes AI and data center chips, accounted for 66% of the company's revenue during the first half of 2026, while smartphones contributed 22%, the company disclosed during its earnings call.

Advanced manufacturing technologies continued to drive results. Chips produced using 7-nanometer processes and below represented 77% of total wafer revenue during the quarter. The 5-nanometer process accounted for 33% of revenue, followed by 3-nanometer technology at 30%, according to figures released by the company and carried by Reuters.

The company said AI-related demand"extremely robust," while noting that customers continue to present aggressive forecasts for future chip requirements. Reuters reported that TSMC expects its full-year revenue in U.S. dollar terms to increase by more than 40% in 2026, up from its earlier projection of more than 30%.

TSMC's latest results arrive days after Dutch semiconductor equipment maker ASML raised its own sales outlook for 2026, citing continued demand for chipmaking tools used in advanced semiconductor production. The developments underscore the continued investment cycle surrounding AI infrastructure across the semiconductor industry, according to Reuters.

Shares of TSMC rose 1.23% in Taipei trading on Thursday and are up more than 58% so far this year. The company, now valued at nearly $2 trillion, remains Asia's most valuable listed company, according to MarketWatch.
