Introduction:
In a revelation that shocked many in the semiconductor world, veteran journalist Lin Hong-wen disclosed at a recent Korean seminar that TSMC has begun referring customers to Samsung when its cutting-edge 3nm and upcoming 2nm production capacity is maxed out. That’s right—the world’s most dominant chip foundry is pointing overflow clients toward its biggest rival.
This move isn’t just pragmatic—it signals something deeper: TSMC may be facing limitations in its once-invincible stronghold.
Is this a rare act of goodwill? Or a red flag revealing capacity bottlenecks, geopolitical hedging, and growing operational pressure?
Overview in 5 Points
TSMC’s foundry capacity is stretched thin amid soaring AI chip demand.
Samsung emerges as the overflow buffer, taking clients TSMC cannot currently handle.
TSMC holds 67.5% of the foundry market share in Q1 2025, aiming for 75% by 2026.
This referral reveals strategic cooperation amid fierce rivalry and geopolitical complexity.
The shift could impact customer loyalty, yield quality perceptions, and competitive dynamics.
“Customer First”—or Under Pressure?
TSMC claims the reason behind this customer redirection is simple: “Customer success comes first.” In a world increasingly driven by AI demand, TSMC argues that trust outweighs control.
But this explanation raises eyebrows. In a fiercely competitive sector, referring clients to your primary competitor is not a sign of strength—it’s an admission that your production ceiling has been reached.
If this overflow continues, TSMC risks diluting its exclusivity and brand power by pushing demand toward Samsung.

Capacity Crunch in the AI Era
The AI boom has created massive strain on chip foundries
Giants like NVIDIA, Apple, and AMD highly seek TSMC’s 3nm and 2nm nodes.
In Q1 2025, AI and HPC clients generated 59% of TSMC’s revenue.
TSMC plans to triple its CoWoS advanced packaging capacity by 2026.
Despite these expansion efforts, the company already faces overwhelming demand.
This situation shows a serious gap between rising AI demand and the available ultra-advanced node capacity—a dangerous trend in a field where leading the race matters most.
A Strategic Hand-Off or a Supply Chain Crack?
TSMC wants to position itself as the “premium core” in a tiered ecosystem:
- Tier 1: TSMC – mission-critical AI chips
- Tier 2: Samsung – overflow and price-sensitive orders
- Tier 3: UMC, GlobalFoundries – legacy nodes
But this tiered model could backfire. What happens when Samsung catches up in yield and performance? TSMC may be giving Samsung not just temporary clients, but long-term relationships—and valuable IP insights.
A Sign of Strategic Weakness?
TSMC’s $100B+ investment in U.S. fabs—while historic—has been riddled with delays, political headaches, and workforce challenges. Meanwhile, the geopolitical chessboard forces Taiwan’s chip titan to hedge bets by showing willingness to “share the load” with Korea’s Samsung.
But this raises concerns: Is TSMC spreading itself too thin? If capacity issues persist, customers may turn to rivals not by referral—but by necessity.

The Bigger Risk: Samsung’s Opportunity
Samsung, often trailing TSMC in yield and trust, now finds itself in a golden position. Referred clients could stay. If Samsung delivers reliable 3nm/2nm performance, it could permanently chip away at TSMC’s lead.
For the first time in years, Samsung may have the edge not by undercutting—but by being endorsed—however unintentionally—by its chief rival.

Conclusion:
TSMC’s decision to refer clients to Samsung might appear generous or ecosystem-minded on the surface. But it exposes real limits in TSMC’s operational capacity and long-term scalability.
The AI gold rush waits for no one, and relying on your competitor to cover your shortfall is a dangerous precedent.
