Generative AI and AI chips take center stage in South Korea’s IT industry
The hottest topic in South Korea’s IT sector is, without question, generative AI, the AI semiconductors that power it, and the race over high-bandwidth memory (HBM). Since the launch of ChatGPT, the global industrial landscape has shifted rapidly, and AI has evolved from a simple software-service battleground into a decisive factor shaping competitiveness across data center infrastructure, semiconductor supply chains, cloud services, search, commerce, and enterprise software. South Korea stands at the heart of this transformation, backed by its strength as a global memory chip powerhouse. In particular, the explosive growth in AI computing demand has sharply increased the need for HBM used alongside GPUs, further elevating the strategic importance of the country’s semiconductor industry. The market’s focus is no longer just on who can build the best AI services, but on who can control both the hardware and the platforms of the AI era.
This shift is also clearly visible in the changing strategies of South Korea’s major IT and platform companies. Naver has been restructuring its business around integrating hyperscale AI into search, advertising, commerce, and productivity tools, while Kakao has focused on advancing AI services and expanding user touchpoints. At the same time, Samsung Electronics and SK hynix are aiming to secure global leadership in memory, semiconductor packaging, and advanced manufacturing processes—the key building blocks of the AI era. In other words, the current story in South Korea’s IT industry is not a single event, but a broader structural transformation in which semiconductors, cloud, platforms, and content ecosystems are all being reshaped at once by the spread of generative AI.
How HBM is reshaping the semiconductor landscape—opportunity and pressure for Korean companies
HBM has become one of the most symbolic buzzwords in South Korea’s IT and semiconductor industries. It is widely seen as an essential component in AI accelerators that must process massive amounts of data at high speed. While conventional DRAM has served as general-purpose memory, HBM has emerged as the strategic memory of the AI era. SK hynix has significantly strengthened its presence in the HBM market through supply partnerships with global AI ecosystem leaders such as Nvidia, while Samsung Electronics is also accelerating efforts to bolster its HBM competitiveness and secure advanced packaging capabilities. This goes beyond simply selling more memory. HBM competitiveness depends on a complex mix of factors including yields, stacking technology, heat management, packaging technology, and customer certification, making it a key indicator of a company’s overall technological strength and supply chain execution.
Still, the opportunities do not come without challenges. The AI semiconductor market offers strong growth potential, but it also comes with high barriers to entry and enormous investment burdens. Expanding production facilities, funding research and development, strengthening back-end processing capabilities, and building customer-specific validation systems all require significant capital. On top of that, uncertainty is growing as U.S. export restrictions on semiconductors to China, global supply chain restructuring, and competition for advanced process technologies all intensify. For Korean companies, that means rising AI demand is creating opportunity at the same time that geopolitical risk and tougher technological competition are increasing pressure. Even so, the market generally believes South Korea’s semiconductor industry is among the most likely to benefit directly from the expansion of AI infrastructure, thanks to the global standing it has already secured in memory semiconductors.
Platform companies enter all-out competition as search, advertising, and work tools shift toward AI
The impact of generative AI does not stop at semiconductors. South Korea’s platform companies are also reorganizing their services around AI. Search is one of the first areas where the change is most visible. Traditional search has centered on links and documents, but generative AI is changing user expectations toward understanding questions and delivering summarized answers. That shift is affecting advertising models, user time spent on platforms, content distribution, and even creator ecosystems. This is why domestic players including Naver and Kakao are strengthening AI search, personalized recommendations, and workplace-assistance functions. To survive, they need more than just the ability to keep pace with foreign Big Tech—they must differentiate themselves through Korean-language data, integration with local services, and the combination of commerce and content.
The enterprise software market is being reshaped along the same lines. As AI is increasingly used for drafting documents, summarizing meetings, assisting with code, handling customer service, and generating marketing copy, the very definition of productivity tools is changing. Korean companies now have to weigh cost and efficiency when deciding between developing their own large-scale AI models and using external ones. Large platform companies are seeking to dominate ecosystems by combining proprietary models with cloud services, while mid-sized firms and startups are trying to stand out with vertical AI services tailored to specific industries. Ultimately, the next phase of competition is likely to be defined less by who built the biggest model and more by who can embed AI most effectively into real work and consumer experiences.
Cloud and data center investment rises, with power and regulation emerging as new variables
As AI competition intensifies, the importance of data centers and cloud infrastructure is also growing. Generative AI requires enormous computing resources not only for training but also for inference, making stable server infrastructure and reliable power supply directly tied to industrial competitiveness. This links the interests of telecom operators, cloud providers, internet companies, and semiconductor makers along a single axis. In South Korea as well, expanding data centers, securing GPUs, and building out infrastructure for enterprise AI services have become major priorities. But data center expansion also brings higher electricity consumption, local community acceptance issues, cooling costs, and environmental regulation into the picture. In other words, the growth of the AI industry is not just a technical issue—it is also an energy and policy issue.
Regulation is another major variable. As the AI industry expands, questions surrounding personal data protection, copyright, the legality of training data, and algorithmic accountability are beginning to emerge in earnest. In content industries such as news, images, video, and music, social consensus will be especially important in determining how generative AI should relate to existing creative works. Korean IT companies must therefore manage regulatory risk while also securing technological competitiveness. If they lose user trust, the spread of AI services will inevitably slow. It is no exaggeration to say that future success will depend not only on model performance, but also on how well companies design transparency, safety, and data governance.
South Korea’s next battleground is the ability to integrate the AI ecosystem
In the end, the core issue facing South Korea’s IT industry can be summed up less as generative AI itself and more as a broader race to integrate the AI ecosystem. In semiconductors, HBM, advanced packaging, foundries, and cooperation around AI accelerators are becoming increasingly important. On the platform side, the key question is how seamlessly AI can be woven into search, advertising, content, and commerce. Cloud and data centers support that foundation, while regulation and data policy determine long-term sustainability. South Korea clearly has areas where it can be strong in the global AI race: world-leading memory technology, a fast pace of digital transformation, a robust mobile-centered service environment, and users who adapt quickly to new technologies.
That said, the challenges are equally clear. In the global competition over large language models themselves, U.S. Big Tech still holds a powerful lead, while China is also catching up quickly on the back of its enormous domestic market and strong policy support. Rather than trying to compete head-on in every area, South Korea needs to concentrate resources where it has practical advantages—semiconductors, local services, industry-specific AI, Korean-language optimization, and enterprise productivity solutions. Only when investment, technology, and policy are aligned in the same direction can South Korea’s IT industry turn the AI era’s opportunities into long-term competitiveness rather than just short-term performance. In that sense, generative AI, HBM, and the AI semiconductor race are not passing trends, but structural issues that will shape the growth path of South Korea’s IT industry for years to come.
