TSMC Faces Supply Crunch as AI Demand Overwhelms Chip Production

The world’s leading semiconductor foundry, Taiwan Semiconductor Manufacturing Company (TSMC), is grappling with a high-class problem: demand for its most advanced chips is vastly outstripping its ability to supply them. A severe shortage of its cutting-edge 3-nanometer manufacturing capacity is forcing the company to prioritize access, leaving some clients unable to secure orders.

Financial Performance Signals Robust Health

TSMC’s formidable market position is underscored by its latest financial results. For the fourth quarter of 2025, revenue climbed 25.5% year-over-year to $33.73 billion, surpassing the company’s own forecast. The firm reported a gross margin of 62.3% and an operating margin of 54.0%. Notably, advanced technologies defined as 7-nanometer and beyond accounted for 77% of total wafer revenue.

Looking ahead, management has provided an optimistic outlook for the full year 2026, projecting revenue growth of nearly 30%. This confidence is rooted in a multi-year demand cycle for AI accelerators, which TSMC anticipates will grow at a compound annual rate in the mid-to-high 50 percent range through 2029.

Allocation Becomes a Strategic Imperative

In the face of constrained 3-nanometer production, TSMC is reportedly granting preferential access only to its “long-term, loyal” customers. Industry giants Apple and Nvidia are understood to be among the primary beneficiaries of this scarce technology. This bottleneck is not viewed as temporary but rather as a structural shift driven by the explosive need for AI accelerators and high-performance computing components—a demand wave so large that even TSMC’s aggressive expansion plans may struggle to fully satisfy it.

Should investors sell immediately? Or is it worth buying TSMC?

To address the capacity shortfall, the chipmaker has outlined capital expenditures between $52 billion and $56 billion for 2026, a significant increase from approximately $40.9 billion the prior year. Between 70% and 80% of this budget is earmarked for advanced process technologies, including 3-nanometer and the upcoming 2-nanometer nodes.

Massive Expansion Underway

The scale of TSMC’s build-out is monumental. In Arizona alone, the company is constructing five new fabrication plants alongside two advanced packaging facilities. This project represents a total investment commitment of $165 billion spread over several years.

Commanding roughly 72% of the global semiconductor foundry market, TSMC remains the indispensable linchpin of the global AI infrastructure. The company’s shares currently trade about 14% above their 200-day moving average, a price level that reflects the sustained tailwind from the ongoing artificial intelligence boom.
