TSMC May sales up 39.6% on strong AI chip demand

Taiwan Semiconductor Manufacturing Co. (TSMC) posted a 39.6% year-on-year revenue increase in May 2025, totaling NT$320.5 billion (US$10.7 billion), despite an 8.3% drop from April 2025.

The growth was driven by chip stockpiling as clients brace for ongoing trade uncertainties.

April 2025 saw a 48% revenue surge, with analysts expecting TSMC’s second-quarter sales to climb 39%.

CEO C.C. Wei projected mid-20% sales growth in US dollar terms for 2025, driven by strong AI chip demand.

Nvidia also forecast strong sales, while Taiwan’s overall exports, including to the US, hit a record in May 2025.

🧠 Food for thought

1️⃣ Pre-tariff stockpiling follows historical pattern of trade uncertainty

TSMC’s 39.6% May revenue jump reflects a broader industry response to trade tensions, similar to patterns seen earlier in 2025.

In March, global semiconductor sales surged to $55.9 billion, representing a 19% year-over-year increase that analysts attributed directly to pre-tariff stockpiling behaviors by manufacturers 1.

This acceleration in purchasing has been particularly pronounced for memory chips and analog ICs, as OEMs and contract manufacturers attempt to secure inventory before potential trade restrictions take effect 1.

The semiconductor supply chain’s vulnerability to geopolitical shifts has created a climate where stockpiling becomes a strategic necessity. However, analysts caution that such growth may not reflect genuine end-market demand but rather defensive procurement strategies 2.

Companies throughout the electronics supply chain have faced extended semiconductor lead times of 4+ months alongside approximately 18% year-over-year price increases, further incentivizing stockpiling behaviors 2.

2️⃣ AI computing creates unprecedented demand concentration in high-performance chips

The AI boom driving TSMC’s growth represents a fundamental shift in semiconductor industry dynamics, with demand concentrated in specific high-performance segments.

Industry projections indicate generative AI chips alone will generate over $150 billion in sales by 2025, explaining why TSMC’s CEO maintains that AI chip demand still outstrips supply despite overall industry expansion 3.
