📈 TSMC, a Head-to-Head Battle Between AI Packaging Expansion and Competitive Variables - 2026.09.12

Here we go~ Onion’s back. TSMC’s August revenue set another record, showing that the fire of AI demand has yet to die down. But this round isn’t simply about looking at revenue figures. How quickly packaging capacity can be expanded, whether next-generation technology partnerships can be connected to actual production, and whether competitors can develop alternatives are all intertwined. 🔥

Strong Revenue, Packaging as the Bottleneck

TSMC’s August revenue came to NT$514.8 billion, up 53.3% from the same month last year ^[1]. Looking only at the revenue trend, demand for AI semiconductors continues to drive TSMC’s manufacturing business. The New York Stock Exchange ADR closed on September 11 at $433.09, up +1.18% from the previous day, with trading volume of 7,301,727 shares. The strong earnings trend and the stock’s one-day movement show that even when they reflect the same factors, their timelines can differ.

The key point here isn’t only the front end, where chips are made. According to reports, TSMC plans to double its CoWoS capacity by 2028 as shortages of AI chips spill over to competitors ^[2]. Even if AI chip demand continues, finished-product supply will struggle to accelerate if packaging becomes a bottleneck. Even when water flows well from the faucet, a thin final hose can leave the stream frustratingly weak. Semiconductors can show a similar pattern when bottlenecks arise in packaging.

CoWoS Expansion, the Centerpiece of the Bull Case

The CoWoS expansion plan appears important because it shows that TSMC views AI demand not merely as an increase in orders, but as a production infrastructure issue. Still, there is a distinction to make here. The article reports a plan to double capacity by 2028; it does not mean that the actual expansion has already been completed ^[2]. So the bull case is clear, but the pace and execution process must be checked separately.

Onion believes TSMC’s bull case is clear under the condition that AI demand and advanced packaging expansion continue together. That’s not simply because Onion is an aggressive investor who reacts first to macro tailwinds; it’s because this material places demand and capacity expansion in the same direction. Of course, the phrase “packaging will double” alone cannot determine the direction of revenue or the stock price. The next checkpoint is whether the expansion schedule, actual utilization rates, and customer orders continue to align.

Next-Generation Technology Partnerships Put Manufacturing Competitiveness to the Test

Reports also emerged that TSMC and ASML are cooperating to advance next-generation semiconductor mask technology ^[3]. It was also reported that TSMC is collaborating to expand large-format photomasks for High NA EUV ^[4], showing that competition in advanced processes is expanding beyond simply bringing in a single piece of equipment to include masks and production technology.

Still, a partnership announcement and mass-production results are not the same thing. Technology cooperation is a factor that strengthens long-term manufacturing capabilities, but what matters for actual investment decisions is when it connects to production and how efficiency and yields are confirmed during manufacturing. Here we go, it may be called next-generation technology, but the bill arrives right away. This is a point where the appeal of advanced technology and the cost of execution must be considered together.

Competitive Landscape and Remaining Questions

After OpenAI joined forces with Samsung Electronics, questions have emerged over whether this could become an alternative that reduces dependence on TSMC ^[5]. This report is meaningful from the perspective that a competitive variable could emerge in TSMC’s supply-chain position. However, the materials do not confirm how much this cooperation will actually change demand for TSMC’s contract manufacturing. Possibilities and confirmed business changes must be kept separate.

Ultimately, the current picture is one in which record revenue and AI packaging expansion form a strong core, supported by next-generation mask technology cooperation. On the other side lie the rise of alternatives from competitors and the pace of expansion execution. There is one central question going forward: How smoothly can TSMC connect the CoWoS expansion and next-generation technology partnerships needed to capture AI demand with real gains in productivity and supply?
