South Korean chipmaker SK Hynix reported a 158% increase in operating profit for the first quarter of 2025.

This surge is attributed to strong demand for advanced chips used in generative AI and customer stockpiling due to concerns over potential US tariffs.

The company posted an operating profit of 7.4 trillion won (US$5.1 billion) for the January 2025 to March 2025 period.

This figure compares to 2.9 trillion won (US$2 billion) during the same period last year.

It also exceeds analysts’ average forecast of 6.6 trillion won (US$4.6 billion), according to LSEG SmartEstimate.

🧠 Food for thought

1️⃣ Memory chips are leading AI’s next growth wave

The huge 158% profit increase for SK Hynix highlights how memory chips have become central to AI infrastructure development.

High-bandwidth memory (HBM) chips, a specialty of SK Hynix, already account for over 40% of the company’s DRAM revenue as of Q4 2024 1.

Industry forecasts suggest memory chip sales specifically for AI applications will surge from $4 billion to $81 billion in the coming years, representing one of the fastest-growing semiconductor segments 2.

This reflects a fundamental shift in computing architecture needs, as AI models require vast amounts of high-speed memory to function effectively, creating sustained demand rather than a temporary spike.

SK Hynix is positioning itself to capitalize on this trend through development of next-generation products like HBM3E and HBM4, designed specifically for high-performance AI computing requirements 1.

2️⃣ Geopolitical tensions are reshaping semiconductor supply chains

SK Hynix’s quarterly results reveal how potential US tariffs are already influencing purchasing decisions, with customers stockpiling chips to mitigate future trade risks.
