South Korea's Trillion-Dollar AI Boom Raises Valuation Concerns in 2026

South Korea's Kospi stock market has reached record highs, with two chipmakers reaching trillion-dollar valuations, driven by explosive demand for AI chips, but experts warn of a potential boom-bust cycle.

The Rise of South Korea's Chipmakers

SK Hynix and Samsung Electronics have joined the trillion-dollar club, alongside Taiwan's TSMC, with $1.03 trillion and $1.05 trillion valuations, respectively. This growth is largely attributed to the increasing demand for chips used in AI applications, with the global AI chip market expected to reach $34.6 billion by 2027, growing at a 37.5% CAGR.

Industry Insights

• The average 4nm chip production cost is around $150 million per wafer, with companies like BYD investing heavily in 4nm smart driving chips.
• The Korea Institute of Startup & Entrepreneurship Development (KISED) is promoting South Korea's startup ecosystem, with 85% of startups in the country focusing on AI and related technologies.

According to a KISED representative, the South Korean government has allocated $1.2 billion to support startups in the AI sector, with a focus on multi-disciplinary research and industry-academia collaboration.

What the Sceptics Say

Some experts argue that the Kospi index is too heavily reliant on the performance of these two chipmakers, with 30% of the index's weight attributed to SK Hynix and Samsung Electronics. This raises concerns about the potential for a sharp decline in the event of a downturn in the chip market.

What This Means for the Industry

Companies like Microsoft, Uber, and Cyera are likely to be impacted by the growth of the AI chip market, with 65% of companies in the sector expected to adopt AI-powered solutions within the next 12-18 months. As the demand for AI chips continues to rise, we can expect to see increased investment in chip design and manufacturing, with a focus on 4nm and 5nm processes.
