The government released a "three mega projects" plan totaling 1,500 trillion won with Samsung Electronics and SK Group, saying it would accelerate nurturing the semiconductor and artificial intelligence (AI) industries, but analysts in the securities market said the actual feasibility matters more than the size of the investment. Because both semiconductor plants and AI data centers require massive amounts of power, water, and secured sites in advance, they noted the speed of building out infrastructure will determine the success or failure of the projects.
According to the industry on the 30th, the mega projects the government released the previous day total 1,500 trillion won, including establishing a southwest semiconductor production base (800 trillion won), building AI data centers (550 trillion won), and next-generation semiconductor research and development (R&D). Samsung Electronics and SK Group separately unveiled long-term, nationwide investment plans, presenting an investment blueprint totaling 4,700 trillion won.
While the securities market viewed the announcement positively as a national-level AI industry strategy, it also saw no shortage of hurdles to clear in actual execution.
Lee Jae-won, an analyst at Yuanta Securities Korea, said, "The core of this project is to simultaneously expand computing infrastructure, memory supply capacity, and capabilities to apply AI to real-world industries, which are the key bottlenecks of the AI era," adding, "Rather than a simple, individual corporations investment announcement, it is an industrial policy move to reorganize a Korea-style AI ecosystem nationwide by tying together expansion of semiconductor production bases, building AI data centers, and the AI transition of robots and manufacturing."
However, Lee said, "Power, water, land, and workforce procurement could act as bottlenecks in actual execution, and while there may be long-term concerns about oversupply in semiconductors, this still cannot alleviate the short-term memory supply shortage," adding, "In the short term, stock reactions will likely diverge by sector depending on factors such as the speed of actual ground-breaking, securing power infrastructure, each corporations' board approvals, and demand visibility, rather than the total investment aggregates."
Samsung Securities also viewed the timing of plant completion as far more important than the investment announcement itself.
Lee Jong-wook, an analyst at Samsung Securities, said, "The impact of the southwest cluster announcement on share prices is limited," explaining, "The announcement of a cluster itself is unrelated to immediate supply changes, and given the nature of infrastructure investment, there is high volatility in completion timing."
He added, "Rather, the timing of fab completion, which allows for concrete forecasting of when equipment investment will occur, had a big impact on share prices," and assessed, "For the two memory companies, this was the moment when a new cluster site after Yongin was needed, and the significance lies in the expansion of semiconductor production sites."
The factor most commonly cited by the securities market was power. Because both semiconductor plants and AI data centers require large-scale electricity, building out the power grid could become a bigger challenge than building production facilities.
Lee said, "Under the currently expanded plans, a power shortage could arise as early as 2031, and there are only five years left."
Hwang Su-uk, an analyst at Meritz Securities, likewise said, "The success or failure of this project depends on the speed of execution for the power grid, water, land, regional electricity pricing, and a dedicated tariff for data centers (AIDC)."
He added, "A total IT load of 18.4 gigawatts (GW) could lead to nearly 40 GW of new power demand," and "Considering the power demand of AI data centers, even more supply plans are needed."
Kim Rok-ho, an analyst at Hana Securities, agreed with the investment direction but cited whether infrastructure will be built as the key variable.
Kim said, "This announcement is the largest-ever investment on the premise of a prolonged supercycle in AI-era memory, a strategic choice to strengthen the global supply chain and secure technological leadership," while adding, "As the magnitude and speed of memory supply increases could accelerate, concerns may persist in terms of the supply-demand balance."
Kim continued, "Despite the willingness to expand semiconductor capacity, it is also necessary to assess feasibility given power and water issues," diagnosing, "The speed of future government budget execution and the process of coordinating permits among local governments will be the key variables that determine the practical feasibility of this semiconductor investment."
On the other hand, some said it could be a catalyst to strengthen Korea's long-term semiconductor competitiveness.
Kim Un-ho, an analyst at IBK Securities, said, "This is the first comprehensive state support since the joint research and development on 4M DRAM in 1986," adding, "Preemptive investment in semiconductors will serve as a chance to widen the gap with latecomers."
He added, "Some have voiced concerns about supply-demand instability due to adjustments in investment schedules, but we judge there will be no abrupt changes in supply-demand conditions because corporations are expected to adjust the pace of investment to market conditions."
