The global semiconductor industry is experiencing an unprecedented boom, largely driven by the surge in artificial intelligence (AI) demand. This period of hyper-growth, however, is raising concerns about its sustainability and the potential for a subsequent downturn. While the current prosperity offers significant economic benefits, industry leaders and policymakers are urged to look beyond immediate gains and prepare for the inevitable cyclical nature of the semiconductor market.
AI Fuels Semiconductor Supercycle
The current semiconductor upswing is characterized by a massive demand for high-performance memory chips, particularly High Bandwidth Memory (HBM), essential for AI accelerators. Companies like Samsung Electronics and SK Hynix, major players in the memory market, have seen their revenues and stock valuations soar. This demand has propelled South Korea’s semiconductor exports to record highs, surpassing $10 billion monthly for the first time in June. Both Samsung and SK Hynix have achieved market capitalizations exceeding $100 billion, attracting significant global investor attention.
This AI-driven demand is a departure from previous semiconductor cycles. Historically, the industry has been subject to boom-and-bust patterns. However, some argue that the fundamental shift brought about by AI could lead to a more sustained period of growth. Others remain cautious, pointing to the industry’s inherent cyclicality and the potential for oversupply.
Signs of a Potential Shift
Despite the current euphoria, signs of a potential market correction are emerging. The stock prices of major semiconductor companies have seen declines of 20-25% from their peaks. Debates continue regarding the longevity of the memory chip “supercycle.” Even with Samsung Electronics reporting record operating profits in the second quarter, some analysts, like those at Morgan Stanley, have issued reports suggesting a near-term reduction in the proportion of memory chips and a preference for hyperscale data center operators.
Market intelligence firms are also forecasting a shift. Bloomberg Intelligence predicts that the memory shortage will peak by the end of this year and could transition into an oversupply situation by early 2028. Will C. Lee, a Harvard Business School professor who has studied semiconductor cycles since the 1980s, commented in a May interview that the current memory boom “cannot last forever, and this too shall pass.” While some believe the AI-driven demand makes this cycle different from past ones, the historical pattern suggests that memory companies will still be subject to cyclical fluctuations.
Navigating the Post-Boom Landscape
The exact timing of the peak and subsequent decline of the current semiconductor boom remains uncertain. Demand is volatile, and major players like Samsung and SK Hynix are already taking steps, such as Long-Term Agreements (LTAs), to mitigate the risks of future oversupply.
A significant concern is that the focus of companies, governments, and markets is primarily on maximizing current profits and determining how to distribute them. This short-term perspective may overshadow crucial long-term strategic planning. The critical question is not just how much money can be made now, but how these companies can leverage this period to achieve quantum leaps and become industry-leading innovators, setting themselves apart from competitors.
Intensifying Global Competition
In key memory markets like HBM, DRAM, and NAND flash, South Korean giants Samsung Electronics and SK Hynix face increasing competition. Beyond established players like Micron in the US and Kioxia in Japan, Chinese manufacturers such as CXMT and YMTC are rapidly emerging. While these Chinese companies may currently lag behind the top-tier memory manufacturers, they are poised to capture significant market share in future cycles.
Strategic Imperatives for the Future
Instead of becoming complacent with the current boom, companies and governments must prioritize developing strategies for the post-boom era. This includes creating robust support systems to ensure a continuous influx of top talent and establishing clear technology roadmaps to identify and lead future markets.
Furthermore, the current period presents an opportune moment to foster the growth of the domestic ecosystem for semiconductor materials, components, and equipment. Neglecting these efforts now could lead to significant regrets in the future, with the painful realization of missed opportunities during a period of unprecedented prosperity.
The semiconductor industry’s cyclical nature is a well-established phenomenon. While the current AI-driven surge offers immense opportunities, proactive planning and strategic foresight are essential to navigate the inevitable downturn and ensure long-term resilience and innovation.
