The Korea Herald reports that TSMC's tight leading-edge capacity is creating an opening for Samsung Electronics' foundry business, as fabless customers weigh alternatives to the world's largest contract chipmaker.

TSMC has struggled to meet demand for its most advanced process nodes, according to the report, leaving customers — particularly those designing AI accelerators and high-end smartphone silicon — searching for second sources. Samsung, the world's second-largest foundry, stands as the most credible alternative at the leading edge, and the Korean company is positioning itself to capture orders that TSMC cannot fulfill.

The dynamic marks a shift in the foundry market's recent balance. TSMC has spent years consolidating its dominance at advanced nodes, winning virtually all major AI chip orders and the bulk of premium mobile and HPC business. Samsung Foundry, by contrast, has faced yield difficulties and a thinner customer roster, and the gap between the two rivals widened through the AI boom.

Capacity scarcity changes that equation. When TSMC cannot allocate enough wafers, customers face a choice: queue for supply or qualify a second manufacturer. Second-sourcing is costly and slow — advanced-node designs must be ported, re-verified and re-taped-out — but for large-volume customers the risk of supply shortfall at TSMC now outweighs the porting cost, the report suggests.

For Samsung, the opportunity comes with conditions. Winning displaced TSMC orders requires demonstrating competitive yields at advanced nodes, committing capacity on 300mm lines, and convincing designers that its process ecosystem — IP libraries, design kits and packaging options — can support products originally targeted at TSMC's technology. The Korea Herald piece frames the moment as a test of whether Samsung can convert a rival's supply constraint into durable share gains rather than one-off overflow business.

The stakes extend beyond the two foundries. Fabless customers and governments have pushed for geographic and supplier diversification in advanced chipmaking, and a stronger Samsung Foundry would give the industry a second scaled leading-edge option outside Taiwan. That geopolitical backdrop adds urgency to customer decisions, though the report's core argument remains commercial: TSMC's capacity is the bottleneck, and Samsung is the nearest alternative with leading-edge capability.

How much share Samsung actually captures will depend on how quickly TSMC expands its own advanced-node capacity and whether Samsung can prove its yields match customer requirements. If TSMC's crunch persists into coming quarters, the foundry market's long-standing concentration at the top could begin to ease — with Samsung as the primary beneficiary.
