Samsung data breach
Although TSMC continues to sit unchallenged at the pinnacle of process technology—commanding an effective 100% share of advanced AI chip manufacturing—two powerful forces, capacity constraints and geopolitics, are increasingly compelling technology giants to seek contingency plans.
According to industry sources, the initial capacity of TSMC’s 2-nanometer process has been almost entirely absorbed by Apple and NVIDIA. As a result, major players including AMD, Google, and Tesla have reportedly begun discussions with Samsung regarding its own 2-nanometer foundry offerings. At the same time, NVIDIA is said to have tested Intel’s 18A process, though these efforts appear to remain confined to the evaluation stage, with no indication of imminent mass-production collaboration.
Korean outlet EBN reports that while TSMC retains a clear technological lead, it is constrained by Taiwan’s “N-2 rule,” which mandates that overseas fabs trail domestic production by two process generations. Consequently, TSMC’s Arizona facility (Fab 21) is not expected to enter 3-nanometer mass production until 2027.
Samsung, by contrast, may gain a critical timing advantage. Its new fab in Taylor, Texas, is expected to begin volume production of its 2-nanometer GAA process as early as 2026. For U.S. technology companies facing pressure to comply with “Made in America” requirements—and unable to secure sufficient capacity from TSMC in Taiwan—this one-year head start is highly attractive. Reports suggest that Samsung Chairman Lee Jae-yong has personally engaged senior executives from AMD, Google, and Tesla to explore potential partnerships.
At present, roughly half of TSMC’s 2-nanometer capacity is rumored to be reserved for Apple, with NVIDIA positioned as the other top-priority customer. In a market defined by scarcity, and with Apple showing no inclination to diversify its foundry partners, it is entirely rational for other firms to consider Samsung as a second source. Reuters has likewise reported that under CEO Lip-Bu Tan’s strategic direction, Intel has conducted chip tests for NVIDIA on its 18A process.
However, insiders emphasize that these efforts have thus far remained strictly at the testing stage, without advancing to mass production. This should not be interpreted as a loss of confidence in Intel’s process technology, but rather as a reflection of NVIDIA’s long-standing preference for stability and risk mitigation.
Examining NVIDIA’s roadmap, its Rubin-architecture GPUs—scheduled for release in 2026—are currently expected to rely on the well-established 3-nanometer node, or potentially TSMC’s A16 process, rather than gambling on less-proven options such as TSMC’s 2-nanometer or Intel’s 18A technologies.
Intel, for its part, appears to be pursuing a more pragmatic course. The company is using its own Panther Lake processors to validate the performance and yields of the 18A node, aiming to demonstrate technical credibility before placing its largest foundry ambitions on the subsequent 14A generation. In my view, 2026 will mark a pivotal year in the reshaping of the global foundry landscape.
While TSMC currently enjoys an overwhelming advantage—holding an estimated 71% market share in the third quarter of 2025—capacity limitations remain its most significant vulnerability. When demand for the most advanced nodes exceeds supply, overflow orders inevitably spill toward Samsung and Intel.
- Samsung’s opportunity lies in timing and geography. If it can deliver 2-nanometer manufacturing on U.S. soil a full year ahead of TSMC, it stands to attract customers like Google and Tesla—companies eager to design their own chips without becoming overly dependent on a single supplier.
- Intel’s opportunity rests in system-level packaging. Even if 18A does not immediately secure marquee NVIDIA contracts, Intel’s recent demonstrations combining 14A and 18A processes with massive Foveros 3D packaging suggest a value proposition that may, for future AI workloads, rival the appeal of process scaling alone.
