TL;DR
Seoul has declared memory, especially high-bandwidth memory (HBM), as the key bottleneck in AI progress. This recognition underscores supply constraints and geopolitical tensions affecting chip supply chains.
Seoul’s government has officially identified memory shortages, particularly in high-bandwidth memory (HBM), as the primary bottleneck hindering AI development. This marks a significant shift in policy focus, emphasizing supply chain vulnerabilities and geopolitical risks affecting semiconductor manufacturing.
The decision follows recent statements from Chey Tae-won, chairman of SK Group, who warned that AI memory demand is expected to grow by 60 to 100 percent in 2027, with current supply unable to meet this surge. Chey highlighted that no significant new capacity is coming online next year, exacerbating an already strained market.
Industry data shows SK hynix holds approximately 58 percent of global HBM revenue in Q1 2026, with Samsung and Micron each holding about 21 percent. The concentration of capacity in a few companies, mostly in South Korea, has raised concerns about supply security and geopolitical influence.
In response, SK hynix announced plans to accelerate capacity expansion, including moving the Yongin mega-cluster’s first clean room to February 2027 and investing over $14.5 billion in new fab facilities. However, these projects will not produce additional capacity until 2027, leaving a ‘gap year’ of shortages in 2026.
Implications of Recognizing Memory as a Strategic Bottleneck
This acknowledgment by Seoul underscores the critical importance of memory supply in AI development. It highlights how capacity constraints and geopolitical concentration could slow AI progress, influence global supply chains, and increase costs. Governments and industry players may now treat memory access as a matter of economic security, potentially leading to new policies and strategic stockpiling.

Memory Industry Concentration and Growing Demand
Recent industry reports indicate that SK hynix controls over half of the global HBM revenue in Q1 2026, with a tight oligopoly involving Samsung and Micron. Demand for high-bandwidth memory has outpaced supply guidance for two consecutive years, driven by AI’s rapid adoption and growth, which now accounts for more than 50% of semiconductor consumption.
Chey Tae-won’s warning reflects broader concerns about the industry’s capacity to meet future demand and the geopolitical risks associated with a highly concentrated supply chain, mainly located in South Korea and the United States.
“No company has meaningful new capacity coming online next year.”

Uncertainties Surrounding Capacity Expansion and Policy Responses
It remains unclear whether SK hynix’s planned capacity expansions will fully address the looming shortage or if geopolitical tensions will further disrupt supply chains. The timeline for new capacity coming online extends into 2027, leaving a significant gap in 2026, and government responses are still evolving.

Key Questions
Why is memory considered the main bottleneck in AI development?
Memory, especially high-bandwidth memory (HBM), is crucial for AI processing. Demand is surging faster than supply, creating shortages that slow down AI training and inference capabilities.
How concentrated is the global HBM market?
In Q1 2026, SK hynix held about 58% of global HBM revenue, with Samsung and Micron each holding roughly 21%, making the market highly concentrated and geopolitically sensitive.
What risks does this concentration pose?
It increases vulnerability to supply disruptions, geopolitical conflicts, and export restrictions, potentially delaying AI advancements and raising costs.
When will new capacity come online to address shortages?
SK hynix’s planned expansions are expected to be operational by 2027, leaving a supply gap in 2026 that could impact AI development and related industries.
How might governments respond to memory shortages?
Governments may pursue policies such as strategic stockpiling, export controls, or incentivizing domestic manufacturing to secure supply chains and reduce geopolitical risks.
