SK Hynix has sold out its entire 2026 memory lineup in advance and argues that AI demand has broken the memory industry’s boom-bust cycle. CEO Kwak Noh-jung has warned the sector faces its most severe shortage ever, with demand projected to significantly outpace supply through 2027. The chipmaker plans to double its production capacity over the next five years.
SK Hynix says generative AI has broken the memory industry’s boom-bust rhythm, and it points to its own order book: the company has already sold out its entire 2026 memory lineup in advance. Its thesis is that AI needs so much memory, and the infrastructure buildout is so sustained, that the traditional dynamics cannot assert themselves in the usual way.
That argument rests on scale. The South Korean chipmaker controls somewhere between 50% and 70% of the high-bandwidth memory market.
A shortage that could run past 2030
CEO Kwak Noh-jung has warned that the global memory chip sector faces what he describes as its most severe shortage ever, with demand projected to significantly outpace supply through 2027. The company’s own projections suggest the imbalance could persist beyond 2030.
SK Hynix therefore plans to double its memory production capacity over the next five years. But executives have noted that customer feedback suggests even those expansions could fall short of actual needs.
Driving the squeeze is high-bandwidth memory, the specialized chips that sit atop Nvidia’s GPUs and power the data centers training and running large language models. SK Hynix is currently the dominant supplier of HBM3E and is ramping up production of the next generation, HBM4.
Record profit and a Nasdaq debut
The figures behind the thesis are large. SK Hynix’s operating profit hit a record 47 trillion won in 2025, nearly doubling the previous year’s result.
SK Hynix’s Nasdaq debut in July 2026 offered another data point on market confidence. Shares rose nearly 13% on their first day of trading. The company is also pursuing US expansion plans, including potential wafer fabrication facilities on American soil.
Samsung and Micron chase the HBM gap
HBM was historically a niche product, but the rise of generative AI since 2023 fundamentally altered that calculus, and SK Hynix executives have characterized the shift as structural rather than cyclical.
Samsung and Micron, the company’s primary competitors, have invested heavily in advanced memory nodes for similar reasons. Yet SK Hynix’s first-mover advantage in HBM and its deep integration with Nvidia’s GPU ecosystem give it a positioning edge that competitors will struggle to replicate quickly.
Two questions will test that. Crypto Briefing points to whether the capacity expansion timeline holds and whether Samsung can close the HBM gap, because the current market structure leaves SK Hynix with almost monopolistic pricing leverage in the segment that matters most.
