HSINCHU, Taiwan—The monthly revenue sheet Taiwan Semiconductor Manufacturing Co. released Wednesday morning carried the number the market had been waiting for: May revenue of NT$416.98 billion, or about $13.2 billion, up 30.1% from a year earlier. The figure, published June 10, landed in the middle of a stretch when AI-related stocks had wobbled for weeks. The foundry’s sales curve kept climbing anyway.
The gain extended a run that shows little sign of breaking. Revenue rose 1.5% from April, and the combined April-May total was up about 24% from the same period last year, according to Bloomberg calculations. For the first five months of 2026, revenue reached NT$1.96 trillion, up 30.0% from a year earlier. Every month this year except February has posted year-on-year growth of more than 17%.
TSMC, the world’s largest contract chipmaker and the exclusive manufacturer of the most advanced processors used in AI training systems, has become the closest thing the industry has to a barometer of the AI buildout. Its customers include Nvidia Corp., Advanced Micro Devices Inc. and Apple Inc. When those companies sell more accelerators and phones, TSMC’s factories hum. The May number suggests the hum is getting louder.
The company’s chairman, C.C. Wei, has told investors that the world’s chipmaking capacity will fall short of AI demand for years to come, a view that underpins one of the most aggressive spending programs in corporate history. TSMC has guided 2026 capital spending as high as $56 billion, a figure that would rival the annual budgets of small countries and exceed what the company spent in any prior year.
Analysts expect second-quarter sales to grow about 35% from a year earlier, according to Bloomberg, a pace that would mark an acceleration from the first quarter. The arithmetic behind that forecast rests on the same assumption that has driven TSMC’s shares for three years: that the biggest cloud companies will keep buying AI chips faster than the industry can make them.
The May report also offered a measure of how the AI trade has evolved. Earlier this year, investors punished chip stocks on worries that spending on AI data centers was peaking. Nvidia’s shares swung wildly in May and June. Yet the orders flowing into TSMC’s fabrication plants in southern Taiwan show no corresponding dip, a gap between the mood of the stock market and the state of the order book that analysts say can persist for months.
What is changing is where the growth comes from. Smartphone and consumer-chip orders, long the foundry’s bread and butter, have stabilized after a sluggish two years. The growth is coming from data-center processors and the advanced packaging that ties them together. TSMC’s CoWoS packaging line, which stacks memory alongside logic chips, remains booked out, and the company is adding capacity as fast as it can build cleanrooms.
The company’s dominant position carries a geopolitical price. Washington and Beijing both treat TSMC as strategic infrastructure. The U.S. has pressed the company to expand production in Arizona, where its first American fab is now ramping. Taiwan’s government, meanwhile, watches every announcement for signs the company might shift its center of gravity. So far, the most advanced manufacturing remains on the island, where TSMC employs tens of thousands of engineers.
For investors, the tension is between a great business and an expensive stock. TSMC’s shares trade at a premium to most global chipmakers, a rating that assumes the AI boom lasts for years. The May revenue figure does nothing to disturb that assumption. If anything, it strengthens it.
The risks are visible too. A slowdown in cloud spending would hit TSMC’s order book within two quarters, given how much of its output feeds data centers. The company’s own guidance for the year assumed slower growth in the second half. And the sheer scale of the industry’s capacity additions, from TSMC’s new fabs to the memory plants of its neighbors, raises the question of whether the supply that comes online in 2027 will meet demand that is still unproven.
None of that showed up in Wednesday’s number. May revenue of NT$416.98 billion was a record for the month and within a whisker of the all-time monthly high. The company reports full second-quarter results in July, and the market’s attention will then turn to margins, which have been squeezed by the cost of ramping new factories.
For now, the takeaway from the monthly sheet is simple: the AI chip cycle that lifted TSMC to a $1 trillion-plus valuation is not slowing, at least not at the factory gate. The stock market can debate the durability of the AI trade all it wants. The machines that make the chips are booked solid.
