Shares of Taiwan Semiconductor Manufacturing rebounded 3.5% to $429.67 in pre-market trading Monday, clawing back a chunk of last week's -6.69% sell-off, after CEO C.C. Wei told shareholders that AI chip demand will outstrip supply for years — and that price increases are coming. The message to Wall Street is blunt: the world's most important chipmaker believes it can charge more and its customers have nowhere else to go.

• A 15% Price Hike With No Real Competitor to Stop It

TSMC is reportedly considering price increases of up to 15% for 3nm chips in the second half of 2026, followed by another 5% to 10% increase in 2027. That pricing power stems from dominance: TSMC held a 70.4% share of the global foundry market in Q4 2025.

None of its major customers have a viable alternative manufacturer for their most advanced products — Samsung Foundry remains a distant second, and Intel's foundry ambitions are still a work in progress. When demand outpaces supply this severely, the seller sets the terms.

• The AI Boom Is Rewriting TSMC's Revenue Mix

The high-performance computing and AI segment now accounts for 61% of quarterly revenue , while smartphones have fallen to just 26%. That shift matters because AI chips use the most expensive, highest-margin manufacturing processes. Gross margin already rose 3.9 percentage points to 66.2% in Q1 2026 , and Q2 guidance projects margins sustaining in the 65.5%–67.5% range on revenue of $39–$40.2 billion. Higher prices on top of that mix could push margins even further.

• Factories Are Full, and $56 Billion in Spending May Not Be Enough

Utilization at TSMC's main 3nm site, Fab 18, remains elevated, with monthly capacity rising from ~130,000 wafers in early 2026 to 160,000–175,000 in Q2.

TSMC has urgently raised its year-end 3nm target from 150,000 to 180,000 wafers per month — roughly 20% above original plans.

Deutsche Bank warned earlier this year that 3nm capacity was fully booked through 2027. Even with capex trending toward $56 billion this year, supply remains structurally tight.

• The Risk: Customers Are Watching the Exit

Wei acknowledged price hikes are on the table, but the shortage is already pushing companies like Apple to diversify away from TSMC for some production.

TSMC's strategy is gradual pricing discipline — protecting margins without forcing clients to accelerate efforts to find alternatives. At a P/E of ~30.5x, the stock's premium assumes this balancing act succeeds. If customers balk, the calculus changes fast.
