TSM (Taiwan Semiconductor Manufactur): Themes, ETFs, and Basket Ideas
Last updated June 2026
Short answer
What does Taiwan Semiconductor Manufactur do?
Taiwan Semiconductor Manufacturing Company (TSMC) is the largest dedicated semiconductor foundry in the world. TSMC is the company that physically manufactures the chips designed by NVIDIA, AMD, Apple, Broadcom, Marvell, Qualcomm, MediaTek, and most other fabless semiconductor companies. The company operates the most advanced semiconductor manufacturing technology in the world, including leading-edge process nodes at 3nm and 2nm.
TSMC's customer concentration is unusual: Apple alone is approximately 25% of revenue, and NVIDIA is another large share. Without TSMC, there would be no Apple A-series chips, no NVIDIA H100 or Blackwell GPUs, no AMD MI300X. Founded in 1987 by Morris Chang, headquartered in Hsinchu, Taiwan. C.C. Wei is CEO. The company also has expanded fab capacity in Arizona, Japan, and Germany.
Where is Taiwan Semiconductor Manufactur heading?
1. AI accelerator capacity is the binding constraint.
Every major AI chip in the world is manufactured by TSMC. Demand for leading-edge capacity (3nm, soon 2nm) materially exceeds supply. TSMC is the bottleneck on the entire AI infrastructure buildout. Customers compete for wafer allocation.
2. Geographic diversification.
TSMC is expanding fab capacity outside Taiwan, in Arizona (USA), Kumamoto (Japan), and Dresden (Germany). The goal is to reduce geopolitical concentration risk and to qualify for CHIPS Act subsidies. Costs at non-Taiwan fabs are higher; margins on overseas capacity are lower.
3. Process node leadership.
TSMC is currently shipping 3nm in volume; 2nm enters volume production in 2026. The technical lead over Intel and Samsung at the leading edge has widened over the past five years. Maintaining this lead is the core competitive moat.
4. The eventual capex cycle correction.
Semiconductor capex is cyclical. After the current AI-driven peak, there will be a downcycle. TSMC's fab utilization can dip materially during corrections, though leading-edge demand is more durable than trailing-edge.
Risks worth tracking: Geopolitical risk is the single largest factor: any escalation between China and Taiwan would severely impact global chip supply. The concentration of advanced manufacturing in Taiwan is the central concern.
Earnings and valuation (approximate, early 2026)
A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Taiwan Semiconductor Manufactur's investor relations page or your broker.
- Revenue (TTM): ~$95 billion
- Operating margin: ~45%
- Net income (TTM): ~$38 billion
- EPS (TTM): ~$7.50
- P/E (TTM): ~25x
- Price to sales: ~10x
- Dividend yield: ~1.3%
- Free cash flow: ~$25 billion annually (heavy capex absorbs much of operating cash)
- Capex: ~$35 billion annually
TSMC's P/E of approximately 25x reflects a balance: its AI-driven leading-edge demand justifies a premium, but geopolitical risk caps the multiple compared to fabless designers like NVIDIA (~50x) or Broadcom (~45x). The risk discount is the unusually wide gap with NVIDIA's multiple.

TSM's competitors
Leading-edge foundry
At the leading edge (3nm and below), TSMC has a meaningful technical and yield advantage over Samsung Foundry (the only other commercial leading-edge fab) and Intel Foundry Services (Intel's external fab business, still ramping). TSMC's share of leading-edge wafer revenue is roughly 90%.
Mature node foundry
At mature nodes (28nm and above), competition is broader: SMIC and Hua Hong in China, UMC and Vanguard in Taiwan, Samsung, and Tower Semiconductor. TSMC is still the largest but margins are lower at mature nodes.

FAQ
What is TSMC's ticker symbol?
+
TSM, listed on the NYSE as an American Depositary Receipt (ADR). Each TSM ADR represents 5 ordinary shares of the underlying Taiwanese company. The Taiwan-listed shares trade under 2330 on the Taiwan Stock Exchange. Officially Taiwan Semiconductor Manufacturing Company. Headquartered in Hsinchu, Taiwan.
Who are TSMC's competitors?
+
At the leading edge (3nm and below), only Samsung Foundry and Intel Foundry Services. TSMC has a meaningful technical and yield advantage; its share of leading-edge wafer revenue is roughly 90%. At mature nodes (28nm and above), competition is broader (SMIC, UMC, Samsung, Tower Semiconductor) and margins are lower.
Why is TSMC so important to AI?
+
Every leading AI chip in the world is manufactured by TSMC: NVIDIA H100, H200, Blackwell, AMD MI300X, Google TPU, AWS Trainium, Microsoft Maia, Apple's M-series and A-series. Without TSMC's leading-edge capacity, there is no AI infrastructure buildout. TSMC is the structural bottleneck.
What is TSMC's P/E ratio?
+
Approximately 25x trailing twelve months as of early 2026. The valuation balances strong AI-driven demand against geopolitical risk (Taiwan-China tensions). The discount versus pure-play AI beneficiaries like NVIDIA reflects the geopolitical concentration concern.
What does TSMC do?
+
TSMC is a contract semiconductor manufacturer (foundry). It physically produces the chips designed by other companies (NVIDIA, Apple, AMD, Broadcom, Qualcomm, MediaTek). It does not sell chips under its own brand. It operates the most advanced semiconductor manufacturing capability in the world, including leading-edge 3nm and 2nm process nodes.
Who owns the most TSMC stock?
+
TSMC's largest shareholder is the National Development Fund of Taiwan (~7%), plus broad institutional holders including BlackRock, Vanguard, and Capital Group. Berkshire Hathaway briefly held a position in 2022-2023 but exited. Insider ownership is low.
Is TSMC an AI stock?
+
Yes, structurally. TSMC is the manufacturing bottleneck for every leading-edge AI accelerator. AI revenue contribution within TSMC's customer mix has grown to be the largest single growth driver, accounting for the majority of incremental capacity expansion and capex commitments. The Arizona fab buildout is partly funded by CHIPS Act money tied to AI supply chain reshoring.
Which ETFs have the most TSMC exposure?
+
SMH (VanEck Semiconductor) holds TSM at ~10.5%, the second-largest holding. SOXX (iShares Semiconductor) added TSM at meaningful weight after its 2021 methodology update. EWT (iShares MSCI Taiwan ETF) holds TSMC at ~40%, by far the dominant Taiwan-focused vehicle. International ETFs like VWO (Vanguard Emerging Markets) and VXUS hold meaningful TSMC weight.
Which thematic baskets typically include TSMC?
+
Two themes on Walnut. AI infrastructure (TSMC is foundational to every leading-edge AI chip) and Semiconductors (the world's largest foundry by revenue). AI infrastructure baskets typically include TSM alongside NVDA and AVGO as the design + manufacturing combination.
How much of SMH is TSMC?
+
Approximately 10.5% as of early 2026. TSM is the second-largest SMH holding behind NVDA (~20.5%). The high concentration reflects TSMC's size as the world's largest foundry plus methodology that lets large international holdings (via ADRs) take meaningful weight in US-listed semiconductor ETFs.
Is TSMC in the S&P 500?
+
No. TSMC is a Taiwanese company and is not eligible for S&P 500 inclusion (which is US-domiciled companies only). It is included in international and semiconductor sector ETFs via its NYSE ADR (TSM). For US S&P 500 indexing, TSMC exposure comes only through ADR-holding ETFs like SMH and various international funds.
What is TSMC's market cap?
+
Approximately $700 billion as of early 2026. TSMC is the largest publicly traded semiconductor company by market cap globally (NVIDIA's market cap is larger because NVIDIA's growth has been more aggressive, but TSMC has been historically the bigger company). It is one of the largest Asia-domiciled public companies.
Does TSMC pay a dividend?
+
Yes. TSMC pays a growing dividend with approximately 1.5% yield as of early 2026. Distributions are paid quarterly in NT dollars and converted for ADR holders. TSMC has been consistent dividend payer for decades, though the growth rate has been moderate as the company has prioritized fab capex reinvestment.
Should I own TSMC directly or through SMH?
+
Both common. Direct TSM ADR ownership gives concentrated foundry monopoly exposure. SMH includes TSM at ~10.5% along with other semiconductor exposure. Many Walnut users hold both: direct TSM for the foundry-monopoly thesis plus SMH for broader semi cycle. Risk to consider: TSM ADR exposes you to Taiwan geopolitical risk; SMH diversifies that across the broader semiconductor universe.
