Nvidia Edges Out Apple as TSMC's Top Customer Amid AI Chip Boom

The Power Shift

Semiconductor analyst Tim Culpan reported that Nvidia likely overtook Apple as TSMC's largest customer in at least one or two quarters of 2025. If that shift did not occur last year, supply chain sources say it is almost certain to happen throughout 2026. TSMC's Chief Financial Officer declined to comment on client rankings when asked, but the evidence points to a clear transition taking place.

The shift became official when TSMC CEO CC Wei visited Apple's Cupertino headquarters last August to deliver unwelcome news to executives including CEO Tim Cook. Apple would need to accept the largest price increase in years, Wei told them. More critically, Apple, which once held a dominant position on TSMC's customer list, would no longer have guaranteed access to production capacity across TSMC's nearly two dozen fabrication plants.

Why AI Chips Consume More Capacity

The transformation reflects the surging demand for AI chips, which take up significantly more wafer space than smartphone processors. Each Nvidia GPU requires a larger footprint per wafer than Apple's chips. Nvidia's Rubin GPU comprises two dies per package, each nearly eight times larger than Apple's A19 processor. This means that when Nvidia places an order, it consumes far more of TSMC's manufacturing capacity compared to an equivalent order from Apple.

Record Breaking Financial Results

TSMC's fourth quarter 2025 results, reported on January 15, 2026, illustrated the industry transformation. Revenue reached 33.7 billion dollars, exceeding guidance, while full year revenue climbed 36 percent to 122 billion dollars. High Performance Computing, which includes AI chips, accounted for 55 percent of fourth quarter revenue and 58 percent of full year 2025 revenue, while smartphones contributed just 29 percent. HPC revenue grew 48 percent last year, compared with only 11 percent for smartphones.

The company announced record capital expenditure plans of 52 billion to 56 billion dollars for 2026, up roughly 32 percent from 40.9 billion dollars in 2025. TSMC also expects revenue to grow approximately 30 percent this year and projects AI accelerator revenue to grow at a compound annual rate in the mid to high 50 percent range through 2029. These projections underscore TSMC's confidence in the sustained demand for AI infrastructure.

Apple's Long Term Advantages

Despite Nvidia's rise, Apple maintains key advantages in its relationship with TSMC. The iPhone maker's chip portfolio spans more than a dozen TSMC facilities, covering products from smartphones to Macs to accessories. Nvidia's manufacturing footprint, while larger in volume, remains concentrated on leading edge AI processors, making it more vulnerable to shifts in the AI market.

Apple has also secured a major position on TSMC's new 2 nanometer node, which entered mass production in the fourth quarter of 2025. The company is expected to use the technology for its A20 processor in the iPhone 18 series. Apple has reportedly secured over 50 percent of TSMC's planned 2nm output for 2026 in Taiwan, demonstrating that despite losing its top customer status, the company remains a crucial partner for the foundry.

The Stability Versus Growth Dilemma

Culpan noted that the AI boom will not last forever, and that Apple offers stability. Wei himself acknowledged the uncertainty, telling investors that he is very nervous about the situation. If TSMC does not manage the transition carefully, it could be a big disaster for the company, he warned.

The challenge for TSMC lies in balancing the explosive growth opportunities presented by AI chip demand against the steady, predictable revenue stream that Apple has provided for over a decade. While Nvidia's revenue for the fiscal year through January 2026 is set to climb 62 percent, Apple's product revenue is on track to grow just 3.6 percent for the 12 months to December 2025.

Pricing and Capacity Constraints

The shift in customer dynamics has given TSMC increased pricing power. The company has informed customers that 2nm wafers will be priced at least 50 percent above 3nm equivalents, with estimates placing flagship mobile chip costs near 280 dollars per unit. Apple has been hit with its largest price hike in recent history for its upcoming A20 chips.

The power dynamic has shifted from what industry analysts describe as a unipolar world centered on Apple to a bipolar world where Apple and AI customers vie for capacity. TSMC can now arbitrage demand between the two sectors to maintain pricing power, a significant change from the era when Apple held unquestioned priority.

Looking Ahead

As the semiconductor industry continues to evolve, the relationship between TSMC and its two largest customer segments will be critical to watch. Apple's share of TSMC revenue has reportedly dwindled to an estimated 16 to 20 percent by early 2026, while Nvidia has surged to account for 20 percent or more of the foundry's top line.

The outcome of this transition will shape not only the fortunes of these three companies but also the broader technology landscape. TSMC's ability to balance the needs of both its traditional smartphone customers and the rapidly growing AI sector will determine whether the company can sustain its position as the world's leading edge chip manufacturer. For Apple, the challenge is adapting to a world where it no longer commands guaranteed priority access to the manufacturing capacity that has been crucial to its product strategy for over a decade.
