TSMC October sales jump 60% as AI chip demand accelerates

TSMC reported October revenue of $17.88 billion, up 59.7% from a year earlier and up 14.7% from September, CNBC reported.

The world’s largest contract chipmaker benefited from strong demand for advanced semiconductors as technology companies continue to pour capital into artificial intelligence infrastructure. The October figure is a monthly record and it confirms that the chip boom that drove TSMC’s third-quarter results is extending into the final quarter of the year.

Taiwan’s broader export data tells the same story. The island’s exports surged 58.9% in October to $96.76 billion, driven by a 61.4% increase in electronic components shipments, according to government data cited by CNBC. Taiwan is the canary in the coal mine for global tech demand, because its export basket is dominated by the chips and components that go into everything from smartphones to data center servers.

The third-quarter context

TSMC’s October revenue follows a record third quarter. The company reported net profit of NT$763.1 billion in Q3, beating analyst estimates, with revenue of NT$1.49 trillion. The operating margin reached 58.7%, exceeding the upper end of management’s guidance range of 58%. A 58.7% operating margin in a manufacturing business is extraordinary, and it reflects the pricing power that TSMC holds in the advanced chip market where it has limited competition.

The company expects capital expenditure from 2026 to 2028 to be significantly higher than the previous three years. That guidance is the clearest signal TSMC can send about its outlook, because capex is a commitment to build capacity that will come online years in the future. When TSMC says it will spend more on factories and equipment, it is saying that it expects demand to be strong enough to fill those factories. The capex guidance is a bet on the AI infrastructure cycle continuing through 2028 and beyond.

TSMC shares closed 2.24% higher on Tuesday amid broader market volatility in Taiwan. The stock has been volatile in recent weeks, partly because of the Nvidia scandal involving CEO Jensen Huang and partly because of broader concerns about the sustainability of AI spending. The October revenue number is a reminder that whatever is happening at Nvidia, the chips that TSMC makes for Nvidia and other customers are selling at a pace that has not slowed.

Taiwan’s short-selling crackdown

The Taiwanese financial regulator announced tighter short-selling restrictions that took effect Monday, cutting the daily limit on intraday short-selling orders from 30% to 3%. The restriction is a response to the volatility in Taiwanese stocks, and it is designed to prevent short sellers from amplifying market declines.

The crackdown is a signal that Taiwanese regulators are concerned about the stability of the market, even as the underlying economy is booming. The export surge and TSMC’s revenue growth are positive signs, but the stock market has been volatile, and the regulator’s action suggests that the volatility is severe enough to warrant intervention. Short-selling restrictions are a blunt instrument that can reduce liquidity and distort price discovery, but they can also prevent panic selling from feeding on itself.

For TSMC specifically, the short-selling restriction may provide some support for the stock price in the short term, because it limits the ability of bearish traders to bet against the company. The restriction is temporary and it does not change the underlying business, but it removes one source of selling pressure at a moment when the stock is already volatile.

The AI demand driver

The demand for TSMC’s chips is driven by the AI infrastructure build that is the dominant theme in the technology sector. Companies like Nvidia, AMD, and Broadcom design chips that TSMC manufactures, and those chips go into the data centers that are being built to train and run AI models. The pace of data center construction has accelerated in the past year, and TSMC’s revenue growth is a direct measure of that acceleration.

The 60% year-over-year revenue growth is not a one-month anomaly. It is the latest data point in a trend that has been building for several quarters. TSMC’s third-quarter revenue grew 36% year over year, and the October figure suggests that the fourth quarter is growing even faster. The acceleration is driven by the ramp of new chip platforms, including Nvidia’s latest GPUs and the custom silicon that hyperscale cloud companies are designing for their own data centers.

The question for investors is whether the growth is sustainable or whether it is a cyclical peak that will be followed by a bust. The history of the semiconductor industry is cyclical, with periods of overinvestment followed by periods of excess capacity and falling prices. But the AI infrastructure cycle is different from previous chip cycles in its scale and duration, because the demand is coming from the largest technology companies in the world, which have the balance sheets to sustain multi-year investment programs.

What I think

TSMC’s October revenue is the most important data point in the technology sector this week. The 60% year-over-year growth confirms that the AI infrastructure build is not slowing down, and it provides a counter-narrative to the concerns about AI spending that have weighed on chip stocks in recent weeks. The Nvidia scandal is a distraction, but TSMC’s numbers are the reality of what is happening in the chip market.

The capex guidance for 2026 to 2028 is the signal that matters most. TSMC is committing to build more capacity over the next three years, and the company has the best visibility into chip demand of any company in the world. When TSMC says it will spend more on factories, investors should listen, because the company does not make that commitment lightly. The capex is a bet on the AI cycle continuing, and TSMC is the most credible voice in the semiconductor industry.

The Taiwanese export data is the broader signal. A 59% increase in exports is not a normal number, and it reflects a level of demand for electronic components that is unprecedented in recent history. The export basket is dominated by chips and the components that go into electronic devices, and the surge is a measure of how much the world is spending on technology. The concentration of chip manufacturing in Taiwan is a geopolitical risk, but it is also a reason that Taiwanese economic data is such a good proxy for global tech demand.

The short-selling crackdown is a concern, because it suggests that the Taiwanese market is fragile enough to warrant regulatory intervention. Short-selling restrictions distort markets and they often fail to prevent the declines they are designed to stop. But the restriction is temporary, and the underlying business at TSMC is strong enough that the stock should be able to find a floor based on the revenue growth and the capex guidance, regardless of the short-selling rules.

The cyclical risk is real. Semiconductor demand has always been cyclical, and there is no guarantee that the AI cycle will be different. But the scale of the investment being made by the hyperscale cloud companies, and the multi-year commitments that TSMC is making to capacity expansion, suggest that this cycle has more room to run. The October revenue number is a data point, not a trend, but it is consistent with a trend that has been building for several quarters and shows no sign of reversing.
