TSMC posted record Q2 profit, up 77% year-over-year, driven by surging AI chip demand. Here's why the earnings beat matters — and why the stock still fell.
Our previous post covered how fears of slowing AI chip demand helped trigger the Kospi's sharp selloff. But when the world's largest foundry, TSMC, reported its Q2 2026 earnings, the numbers told a very different story from what markets had feared.
TSMC's Q2 by the numbers
TSMC reported its Q2 2026 results on July 16, 2026:
- Revenue: $40.2 billion, above the top end of company guidance and ahead of the $39.94 billion consensus estimate
- Net profit: up 77.4% year-over-year, marking a record high for the 5th consecutive quarter
- Gross margin: 67.7%, above the company's own guided range
- Advanced processes at 7nm and below accounted for 77% of total wafer revenue
On top of that, TSMC raised its full-year 2026 revenue growth guidance from the low-30% range to just above 40%. The company also significantly increased its 2026 capital expenditure target, from a previous ceiling of $56 billion to as much as $64 billion.
"The AI chip supply-demand gap could last until 2029 or 2030"
Comments from the post-earnings conference call stood out. TSMC CEO C.C. Wei noted that the gap between AI chip supply and demand remains "very large," and emphasized that AI is emerging as a new industry with sweeping influence across computing, automotive, and robotics. Analysts pressed on whether this supply shortfall could persist into 2029 or 2030 — underscoring just how focused the market has become on the question of how long the AI boom can run.
Bloomberg Intelligence noted that TSMC's results show "AI server and processor demand is more than offsetting weakness in the smartphone and PC markets." Because TSMC manufactures the vast majority of advanced chips — from Nvidia's AI accelerators to Tesla's automotive processors — its results are widely seen as the key barometer for global AI infrastructure investment trends.
So why did the stock fall anyway?
Despite the strong results, TSMC and other chip stocks broadly sold off. TSMC shares fell 1.55% in after-hours trading, and related names like AMD (-2.7%), Intel (-1.9%), and Micron (-2.4%) declined in sympathy.
This is a classic case of "sell the news." TSMC shares had already surged roughly 71% year-over-year heading into the report, pushing its market cap to roughly $1.96 trillion. At that valuation, even a picture-perfect earnings beat can trigger a rapid valuation reset (multiple compression) if forward margin guidance disappoints even slightly. TSMC's aggressive capex expansion plans, paired with guidance for margin pressure in the current quarter, gave investors reason for caution.
What this means for Korean chipmakers
TSMC's results offer a useful counterpoint to the narrative behind the Kospi selloff covered in our previous post — namely, the idea that "Meta's cloud business pivot = weakening AI compute demand." The fact that underlying AI chip demand remains robust suggests that excessive pessimism about the medium-term outlook for Samsung Electronics, SK Hynix, and other Korean memory chipmakers may be overdone, according to most brokerage analysts.
That said, investors should keep the following in mind:
- High valuation risk: Even strong earnings can trigger short-term pullbacks if much of the good news is already priced in
- The double edge of capex expansion: Aggressive capital spending supports long-term growth but can pressure near-term profitability
- Expanded Arizona investment: TSMC also announced an additional $100 billion investment in its Arizona chip plant, a move worth watching amid the broader US-China tech rivalry and geopolitical risk diversification
Bottom line
TSMC's Q2 results are a strong signal that the AI chip supercycle hasn't lost steam. But in a high-valuation environment, even great earnings can weigh on near-term share prices. In our next post, we'll examine how the expiration of Section 122 tariffs and a looming Section 301 measure could affect Korean exporters, including chipmakers.
