Taiwanese chipmaker TSMC will invest an additional $100bn in the US state of Arizona, the company said Thursday, as it reported a record quarterly net profit on the back of massive demand for AI hardware.
The firm is the biggest contract maker of microchips used in everything from Apple phones to Nvidia processors and has been a major beneficiary of the global AI race.
Governments and tech giants are pouring huge sums into building data centres that can train and run AI tools such as chatbots, image generators and agents that can execute tasks.
This has turbocharged business for chipmakers such as TSMC, creating shortages and sending prices soaring.
"The AI megatrend continues to drive the need for more and more computation," chairman CC Wei told an earnings call.
"We now expect our full-year 2026 revenue growth to be slightly above 40 % year-over-year in US dollar terms."
TSMC's net profit for April to June surged 77.4% year-on-year to NT$706.6bn ($22 bn), smashing analyst estimates of NT$624.4bn.
Wei said TSMC was moving "as fast as possible" to increase its chipmaking capacity in Taiwan, Japan and the US to try to catch up to customer demand.
"The demand and the supply, the gap is so big, so we are working very hard to narrow the gap," Wei said.
TSMC will spend an additional $100bn building fabs in Arizona, which would take the company's total investment plans in the US to $265bn.
"This is to build several or more semiconductor logic wafer fabs for 2-nanometer and below technologies as well as advanced packaging fabs," Wei said.
Chief financial officer Wendell Huang said TSMC will increase its 2026 capital expenditure budget to between $60bn and $64bn "as we continue to invest heavily to support our customers' growth".
"At TSMC, a higher level of capital expenditures is always correlated to higher growth opportunities in the following years," Huang said, adding the company did not expect "any bottlenecks to our capacity expansion plan".
Ahead of the results, Counterpoint Research senior analyst William Li said TSMC's surge in revenue showed "AI infrastructure investment remains exceptionally strong despite macro uncertainty."
"Demand for AI GPUs, AI ASICs and advanced packaging continues to exceed expectations," Li told AFP.
Li said: "EUV (extreme ultra-violet lithography tools) supply constraints and overseas fab investments may limit capacity expansion and weigh on margins in the near term."
Concerns about overstretched valuations in the tech sector have fuelled fears of a market bubble, along with questions over when the eye-watering sums being spent on AI will reap returns.But Omdia principal analyst Simon Chen said those fears were "overstated".
"The demand we see is structural, backed by massive, tangible capital expenditures from hyperscalers," Chen said.
