Nvidia Overtakes Apple as TSMC's Top Client Amid 31st-Ranked Trading Volume Slide

Market Snapshot

On February 27, 2026, TSMC’s stock closed with a 0.59% decline, reflecting modest weakness in investor sentiment. Trading volume for the day stood at $3.37 billion, a sharp 38.22% drop from the previous day’s activity, ranking the chipmaker’s stock 31st in terms of liquidity across the market. While the price movement was relatively contained, the significant contraction in trading volume suggests reduced short-term interest or uncertainty among traders.

Key Drivers

Nvidia’s emergence as TSMC’s largest customer in 2025 marked a pivotal shift in the foundry’s revenue structure, with the AI chipmaker contributing NT$726.9 billion (US$23.2 billion) to TSMC’s top line. This represents a doubling of revenue from the prior year and elevates Nvidia’s share of TSMC’s total income to 19%, up from 12% in 2024. The transition reflects the explosive growth of the AI sector, which is increasingly driving demand for advanced semiconductor manufacturing. In contrast, Apple—long TSMC’s top client—saw its contribution decline to 17% of revenue in 2025, down from 22% the previous year, despite a 3.33% nominal increase in dollar terms.

The shift underscores TSMC’s strategic alignment with high-growth industries. Analysts attribute this trend to Nvidia’s dominance in AI infrastructure, particularly its demand for cutting-edge chip nodes tailored for machine learning and data center applications. This dynamic is further reinforced by Nvidia CEO Jensen Huang’s public confirmation of the company’s status as “client A,” a designation linked to the largest revenue segment in TSMC’s financial disclosures. The partnership not only secures a critical revenue stream for TSMC but also positions the foundry at the forefront of next-generation computing technologies.

Looking ahead, industry observers anticipate Nvidia’s lead will persist in 2026, driven by sustained momentum in AI adoption across cloud computing, autonomous systems, and enterprise solutions. This projection is bolstered by Nvidia’s recent commitment to establish a new headquarters in Taipei’s Beitou-Shilin Technology Park, a move signaling long-term investment in the region. For TSMC, the decision strengthens its ecosystem of high-value clients and reinforces its role as a key enabler of AI innovation.

TSMC’s broader market position remains robust, with the foundry maintaining approximately 70% of the global chip manufacturing market in 2025. Its dominance stems from a combination of technological leadership, economies of scale, and a fabless business model that attracts major tech players. The company’s ability to generate strong operating margins, despite intense industry competition, highlights its competitive advantages. These include a diversified customer base, which now includes both AI pioneers like Nvidia and traditional clients like Apple, and a relentless focus on R&D to maintain its edge in advanced process nodes.

While the immediate price decline on February 27 may reflect short-term market adjustments or unrelated sector-wide factors, the underlying fundamentals for TSMC remain strong. The transition to Nvidia as its largest client aligns with the foundry’s long-term strategy to capitalize on high-growth verticals, ensuring a steady pipeline of demand for its advanced manufacturing capabilities. As AI-driven technologies continue to evolve, TSMC’s ability to adapt and innovate will likely remain central to its sustained success in the global semiconductor landscape.
