TL;DR
Seoul authorities have declared memory, especially high-bandwidth memory, as the main bottleneck in AI development. This stems from a significant demand-supply gap and geopolitical concerns involving a few dominant companies. The development underscores potential risks for AI progress and global supply chains.
Seoul’s government has officially declared memory capacity as the primary bottleneck in the advancement of artificial intelligence (AI), citing a significant imbalance between soaring demand and limited supply. This statement, made during a recent industry briefing, highlights a critical challenge that could slow AI progress and impact global tech markets.

The declaration was made by a senior official from Seoul, who emphasized that demand for AI memory is expected to grow by 50-60% in 2027 compared to this year, with some customers requesting up to 100% more capacity. Despite this, no significant new capacity is expected to come online in 2026, creating a looming supply shortfall.
The official pointed out that the imbalance is most acute in high-bandwidth memory (HBM), which is critical for AI accelerators. Currently, a small number of companies—primarily SK hynix, Samsung, and Micron—dominate the global HBM market, with SK hynix holding approximately 58% of revenue in Q1 2026. This oligopoly raises concerns about supply security and geopolitical risks.
Furthermore, the official warned that geopolitical tensions are escalating, with governments increasingly treating memory access as an issue of economic security. This could lead to more restrictive policies and further complicate supply chains, potentially affecting AI development worldwide.
Implications of Memory Shortage for Global AI Progress
This declaration signals that the AI industry faces a significant supply constraint in memory technology, which could slow down the development and deployment of advanced AI models. The concentration of market share among few suppliers increases risks of supply disruptions and geopolitical conflicts, potentially impacting innovation and market stability.
Additionally, the warning about high memory prices and ‘chipflation’ suggests that costs for AI hardware could rise, affecting both enterprise and consumer markets. The strategic importance of memory capacity underscores its role as a critical factor in AI competitiveness and national security.

Memory Market Concentration and Industry Capacity Plans
As of Q1 2026, SK hynix controlled 58% of the global HBM revenue, with Samsung and Micron each holding roughly 21%. This tight oligopoly means that most of the critical capacity resides in a small number of fabs located mainly in Asia, raising concerns about supply resilience. Despite ongoing capacity expansions, such as SK hynix’s planned investments in Yongin and Cheongju, none of these new facilities will be operational before 2027, creating a ‘capacity gap’ for 2026.
In response, SK hynix announced a series of investments, including a major plant conversion and new fab site reviews, but these will not address the immediate shortfall. The industry’s projected compound annual growth rate (CAGR) of 33% for HBM through 2030 suggests persistent demand outpacing supply for years to come.
Meanwhile, the industry’s physics imply that current capacity expansions will not meet the 2027 demand surge, risking a bottleneck that could hinder AI model training and inference at scale.
“No company has meaningful new capacity coming online next year.”
— Chey Tae-won, SK Group Chairman
Uncertainties Surrounding Future Capacity and Geopolitical Impact
It remains unclear how quickly new capacity will come online beyond SK hynix’s announced projects, and whether geopolitical tensions will lead to actual restrictions affecting supply chains. The precise impact on AI development timelines and costs also remains to be seen, as industry responses and government policies evolve.
Next Steps in Industry Capacity Expansion and Policy Response
Industry players are likely to accelerate investments in new manufacturing facilities, with SK hynix’s Yongin plant now scheduled for February 2027. Governments may also increase strategic stockpiles or impose export controls, further influencing supply dynamics. Monitoring these developments will be crucial to understand how the memory bottleneck will be addressed and how AI progress will be affected in the coming years.
Key Questions
Why is memory capacity considered the main bottleneck in AI development?
Memory, especially high-bandwidth types like HBM, is essential for training and inference in AI models. The current demand exceeds supply, and limited capacity expansion means AI progress could slow down or become more expensive.
Which companies dominate the memory market, and why does it matter?
SK hynix, Samsung, and Micron control most of the critical memory supply, with SK hynix holding a majority. This concentration increases risks of supply disruptions and geopolitical conflicts impacting AI development.
When will new memory capacity be available to meet demand?
Most planned capacity expansions, including SK hynix’s Yongin plant, are scheduled for 2027 or later, leaving a short-term supply gap in 2026.
How might geopolitical tensions influence memory supply chains?
Governments are increasingly viewing memory access as a matter of economic security, which could lead to export restrictions or stockpiling, further constraining supply and raising costs.
What can AI developers do to mitigate the memory bottleneck?
Developers might focus on optimizing models for lower memory use, prioritize local inference hardware, or diversify supply sources, but fundamental capacity constraints will still pose challenges.
