TSMC's 689% Surge Since 2022 Highlights Its Pivotal Role in AI Chip Manufacturing
Taiwan Semiconductor Manufacturing (TSMC) has gained 689% since the launch of ChatGPT in 2022, driven by its dominant role in fabricating AI chips for major tech clients. Despite being less discussed than peers like Nvidia, TSMC reported a 34% year-over-year revenue increase in Q2 2026, with gross margins reaching 67.7%. The company is expanding its U.S. operations in Arizona to mitigate tariff risks and support clients like Apple and Nvidia, while management maintains high confidence in the long-term AI trend despite short-term margin pressures from increased capital expenditures.
Key points
- TSMC stock has risen 689% since 2022, outperforming many AI-related stocks.
- Q2 2026 revenue grew 34% year-over-year, exceeding guidance.
- Gross margin improved by 1.5 percentage points to 67.7%, and operating margin rose to 60.3%.
- TSMC manufactures chips for diverse clients, including Nvidia, Broadcom, Apple, and Amazon.
- The company opened a new facility in Arizona to reduce tariff exposure and improve proximity to key clients.
- Management expects short-term gross margin pressure due to higher capital expenditures but links this to future growth opportunities.
Background
TSMC is a leading semiconductor foundry that fabricates chips based on client designs, rather than designing them itself. Its business model allows it to benefit from the growth of multiple major technology companies simultaneously. The company has been a critical supplier for AI hardware, including GPUs and CPUs, since the rise of generative AI in 2022. Recent expansions into the U.S. market aim to address geopolitical and tariff-related risks while strengthening relationships with major clients based in California.
Why it matters
TSMC's performance underscores the importance of the semiconductor supply chain in the AI boom. Its diversified client base and strong financial metrics suggest that AI growth is not limited to chip designers but extends to manufacturers. The expansion into the U.S. may help stabilize supply chains and reduce dependency on single-region manufacturing, potentially influencing global tech infrastructure and trade policies.
What to watch
Investors will monitor TSMC's ability to maintain high margins despite increased capital expenditures. Future earnings reports will indicate whether the Arizona facility and other expansions successfully offset short-term cost pressures. Continued growth in AI demand from hyperscalers will likely drive further revenue increases, while geopolitical factors may influence the pace of U.S. manufacturing expansion.
