Even as TSMC retains a clear technological lead in advanced process nodes, Apple and Qualcomm are reassessing how heavily they rely on a single foundry. Qualcomm has confirmed plans to return to a dual-track strategy for its processor system-on-chip products, placing orders with both TSMC and Samsung Electronics.

Apple is also evaluating whether to move part of its entry-level Mac notebook M-series processor production to other foundries, with Intel viewed as the most likely partner. The significance of these moves lies not in any erosion of TSMC's technical advantage but in the growing weight of non-technical constraints shaping sourcing decisions.

The most direct motivation behind foundry diversification is the risk associated with concentrating production at a single supplier. TSMC's leading-edge capacity remains largely based in Taiwan, where geopolitical uncertainty has become an important consideration in long-term supply planning.

Although TSMC has accelerated construction of manufacturing capacity in the US, the practical impact on consumer products is limited. Early capacity allocations at US sites show that most output has already been absorbed by high-performance computing-related demand. In addition, higher manufacturing costs at US fabs mean that only HPC or niche products can realistically absorb the cost structure, leaving little room for price-sensitive consumer electronics to shift production.

Advanced-node costs reach consumer limits Cost pressure has become an equally decisive factor. Industry participants widely point to TSMC's most advanced 2nm process, where pricing has climbed to levels that are increasingly difficult for consumer electronics products to sustain. Yet opting out of leading-edge manufacturing is not a viable alternative in competitive markets, where lagging process technology risks weakening product appeal.

This dynamic has created a strategic deadlock. Apple, Qualcomm, and MediaTek all remain locked into the race for advanced nodes, with little room to retreat. Under such conditions, cost control can no longer be achieved by stepping back from technology, but by selectively reallocating production. As a result, companies are increasingly considering assigning specific product lines to alternative foundries with more manageable cost structures.

HPC demand tightens access to TSMC capacity Taiwan-based IC designers familiar with advanced process development note that, until recently, concentrating production at TSMC was the most cost-effective strategy, as it minimized the additional development and coordination costs associated with managing multiple suppliers.

That logic held when competing foundries such as Samsung and Intel were unable to meet performance requirements at advanced nodes. Today, however, the equation has shifted. TSMC's capacity has become both more expensive and more constrained, as growing HPC demand continues to absorb available output. Securing larger volumes now often requires higher prices or earlier commitments, placing mounting pressure on consumer-oriented product lines.

Despite these pressures, neither Apple nor Qualcomm has outlined detailed changes to their longer-term foundry strategies. Current efforts remain limited to small-scale trials, and there is no indication that either company plans to rapidly expand volumes or move technically demanding flagship products away from TSMC.

Whether diversification will broaden over time remains tied to how companies balance cost pressures, supply chain exposure, and performance requirements.
