🚨 My new book From Boom to Bust is now available on Amazon Kindle.
A deep dive into the biggest financial crises in history — from 1929 to 2022 — and the warning signs smart investors learned to recognize before the collapse.
Artificial intelligence has become the defining investment theme of this decade. Every earnings season, investors closely watch companies like NVIDIA, AMD, Broadcom, Microsoft, and Amazon, searching for clues about where AI demand is heading.
However, there is one company that quietly sits at the center of this entire ecosystem.
That company is Taiwan Semiconductor Manufacturing Company (TSMC).
Its second-quarter 2026 results were more than just another earnings beat—they were another confirmation that the AI infrastructure cycle is still in its early stages.
While many investors continue debating whether AI valuations have become excessive, TSMC’s latest results suggest that the underlying demand for advanced computing power remains exceptionally strong.
A Quarter That Exceeded High Expectations
TSMC reported second-quarter revenue of US$40.2 billion, representing 36% year-over-year growth and 12% sequential growth. Even more impressive was the profitability behind those sales.
Net income surged 77% year over year, while earnings per share reached a new quarterly record. For a company already generating well over $150 billion in annualized revenue, maintaining this level of growth is extraordinary.
Many companies can grow quickly.
Very few can grow this quickly while simultaneously expanding margins.
That is exactly what TSMC accomplished.
Gross margin reached 67.7%, operating margin climbed to 60.3%, and net profit margin exceeded 55%.
These numbers are almost unheard of for a manufacturing business.
They demonstrate that TSMC is no longer competing primarily on production costs. Instead, it enjoys exceptional pricing power because its most advanced manufacturing technologies have become indispensable to the world’s leading semiconductor designers.
The AI Demand Story Is Becoming Even Stronger
The most important takeaway from this quarter was not simply the revenue growth.
It was the composition of that growth.
Advanced process technologies—7-nanometer and below—represented 77% of total wafer revenue. Within that mix, 3-nanometer production continued to expand rapidly, accounting for nearly one-third of total wafer sales.
Even more interesting was the early contribution from TSMC’s new 2-nanometer technology.
Although it represented only 3% of wafer revenue during the quarter, management highlighted that production will ramp aggressively during the second half of the year.
That detail should not be overlooked.
Every major technology transition historically brings higher average selling prices, stronger customer commitment, and improved profitability.
The 2nm transition appears likely to follow the same pattern.
As AI models become larger and more computationally demanding, customers increasingly require chips that deliver greater performance while consuming less power.
Those improvements depend heavily on access to the world’s most advanced manufacturing nodes, an area where TSMC remains years ahead of most competitors.
The Hidden Advantage Investors Often Miss
When investors discuss AI, the conversation usually revolves around GPU manufacturers.
NVIDIA receives most of the attention.
AMD continues gaining momentum.
Broadcom benefits from custom AI accelerators.
Apple is investing heavily in on-device AI.
But regardless of which company ultimately wins the AI hardware race, one fact remains unchanged.
Nearly all of them depend on TSMC.
Unlike individual chip designers, whose market share can fluctuate over time, TSMC benefits from the overall expansion of the semiconductor industry itself.
It supplies virtually every major technology leader.
This creates one of the strongest competitive positions in the global equity market.
Instead of betting on a single AI champion, investors owning TSMC gain exposure to the success of almost the entire AI ecosystem.
That diversification is an enormous strategic advantage.
Guidance Suggests Momentum Is Accelerating
If the second quarter was impressive, management’s outlook for the third quarter was arguably even stronger.
TSMC expects revenue between US$44.6 billion and US$45.8 billion, implying another quarter of double-digit sequential growth.
Equally important, management expects gross margins to remain between 65% and 67%, despite continuing heavy investment in overseas manufacturing capacity.
This guidance suggests that demand remains significantly ahead of available supply for leading-edge semiconductor production.
For investors, this matters because it indicates that the AI investment cycle is far from reaching its peak.
Cloud providers continue investing aggressively.
Enterprise AI adoption continues expanding.
Demand for high-performance computing remains exceptionally healthy.
TSMC sits directly in the middle of these trends.
Financial Strength Supports Long-Term Growth
One aspect that deserves more attention is TSMC’s financial strength.
The company generated enormous operating cash flow while simultaneously investing heavily in future production capacity.
Capital expenditures remain among the highest in the world, yet TSMC continues to strengthen its balance sheet, increase shareholder equity, and maintain significant cash reserves.
This financial flexibility gives management the ability to continue expanding manufacturing capacity without compromising shareholder returns.
Few companies possess both the profitability and the balance sheet necessary to invest at this scale.
That advantage becomes increasingly important as semiconductor manufacturing grows more capital intensive.
The Competitive Moat Continues to Widen
Manufacturing leading-edge semiconductors has become one of the most difficult engineering challenges on Earth.
The barriers to entry are enormous.
Building advanced fabrication facilities requires tens of billions of dollars, years of process development, highly specialized talent, and an ecosystem that has taken decades to establish.
Every new technology generation makes catching TSMC even more difficult.
As customers migrate toward 2nm and eventually beyond, the company’s technological leadership becomes increasingly valuable.
This is not a business where competitors can simply invest more money and close the gap within a few years.
The moat is built through decades of accumulated expertise.
That competitive advantage is becoming stronger with every technology transition.
Risks Should Not Be Ignored
Despite the outstanding quarter, investors should remain aware of the company’s primary risks.
Geopolitical tensions surrounding Taiwan remain the largest uncertainty.
Although TSMC continues diversifying production into the United States, Japan, and Europe, a significant portion of its most advanced manufacturing capacity is still concentrated in Taiwan.
Another consideration is the cyclical nature of semiconductor demand.
Although AI spending remains exceptionally robust today, future demand ultimately depends on continued investment from hyperscale cloud providers and enterprise customers.
For now, however, there is little evidence suggesting that this investment cycle is slowing.
On the contrary, management’s guidance indicates continued acceleration.
My Investment Perspective
Following these results, my long-term investment thesis remains unchanged—and perhaps even stronger.
TSMC is no longer simply the world’s largest semiconductor foundry.
It has become one of the most important infrastructure companies powering the global AI economy.
Its combination of technological leadership, extraordinary profitability, disciplined capital allocation, and structural exposure to artificial intelligence makes it one of the highest-quality businesses available to long-term investors.
Short-term market sentiment will inevitably fluctuate, and valuation will continue to move with broader market expectations.
But from a fundamental perspective, the business continues to execute at an exceptional level.
As the 2nm production ramp accelerates and AI demand continues expanding across industries, I believe TSMC remains well positioned to deliver attractive long-term shareholder returns.
For investors seeking exposure to the AI revolution without having to predict which individual chip designer will dominate the next decade, TSMC remains, in my opinion, one of the strongest and most resilient investment opportunities in the entire semiconductor industry.
