Taiwan Semiconductor Manufacturing Co. closed at a record NT$2,575 on October 5, 2026, pushing its market value to about $2.5 trillion. AI-driven demand for its most advanced chips and a rebound in US tech stocks drove the rally, with earnings due later this month.
TSMC shares touched an intraday high of NT$2,580 before closing at NT$2,575, up 3% on the day — an all-time record for the chipmaker. The close lifted TSMC's market capitalization to roughly NT$66.9 trillion, or around $2.5 trillion.
TSMC did not rally alone. The Taiwan Weighted Index, known as TAIEX, also closed at a record 49,712.04 after a 2.55% gain. Trading volume on the index topped NT$1.15 trillion.
Two forces behind the rally
A rebound in US technology stocks lifted the wider chip sector, and continued demand tied to artificial intelligence added further momentum. AI developers keep turning to TSMC for its most advanced chips and its contract manufacturing services. As a result, TSMC shares have gained more than 55-60% year to date.
Revenue is doing the heavy lifting
TSMC's growth is not just a stock-price story. August sales jumped 53% compared with the same month a year earlier. For the full year, the company's 2026 revenue growth is projected at slightly above 40% in US dollar terms.
TSMC is spending heavily to keep pace with that demand. Its capital expenditure guidance sits between $60 billion and $64 billion, spending that only pays off if AI demand stays strong.
Potential new partners add to the optimism
Discussions with Elon Musk's Terafab about a manufacturing facility in Texas are adding to the optimism, though those talks remain discussions, not a signed deal. Any formal agreement on a Texas facility would expand TSMC's footprint.
TSMC is set to release its September sales figures on October 8, followed by third-quarter earnings on October 15.
