TSMC reported its latest record quarter on Thursday, driven by strong demand for its advanced chipmaking technologies. The company expects fourth-quarter revenue to be 58% higher than a year earlier.
But the AI boom has created unrelenting pressure on TSMC's manufacturing lines. Last year, the company said it had the capacity to make more than 17 million 12-inch equivalent wafers. Customers want more.
"The competition is extremely fierce," said Jordan Klein, an analyst at Mizuho Securities. "It's a game of who can get the most leverage and supply."
TSMC North American CEO Sajiv Dalal told CNBC he receives at least 10 calls a day about wafer capacity.
The company produces the vast majority of the world's most advanced semiconductors, including graphics processors and central processors from Nvidia, AMD and Broadcom, plus custom in-house AI accelerators for an expanding roster of tech giants.
Klein warned that if compute demand continues to grow at the current rate over the next 12 to 18 months, capacity constraints at TSMC could threaten some of the industry's massive infrastructure investments and the "aggressive revenue growth targets" from AI companies.
