Summary

Executive Director Park Se-ik presents a deep dive into SK Group's 15 GW AI data center megaproject, drawing parallels with Google's full-stack AI monetization to argue for a major re-rating of SK Telecom as the prime listed vehicle. Dr. So Hyeon-cheol adds a technical layer, highlighting ESS battery demand as a turnaround catalyst for SK Innovation and recommending the neglected construction sector as a data center build-out play. Naver is contrasted as financially constrained for hyperscale data centers, warranting avoidance.

  • Park Se-ik outlines SK Group's 15 GW AI data center plan across Ulsan, Yongin, Suncheon, aiming to become a global AI infrastructure hub.
  • He maps Google's cloud/AI profit cycle onto SK's vertical integration (HBM, cooling, fuel cells, telecom cloud) as a monetization strategy.
  • SK Telecom is identified as the central listed proxy, with valuation scenarios projecting 35% to 100% upside and a 200,000 won target.
  • Dr. So argues that AI data center ESS battery demand could revive struggling SK On, providing a turnaround catalyst for SK Innovation.
  • He suggests the Korean construction sector as a simpler, depressed beneficiary of the inevitable data center construction spending.
  • Naver is viewed as lacking the financial capacity and scale strategy for mega AI data centers, limiting its upside in this theme.
  • Technical caution on SOFC fuel cells and liquid cooling does not derail the core investment thesis.
Ideas
Park Se-ik CEO, ex-Chief Strategist 13:30
Avoid Naver on AI data center scale limits.
Naver lacks the financial muscle for mega‑scale AI data centers. With total equity of only about 31 trillion won and annual free cash flow of 1.8–8 trillion won, it cannot fund multi‑trillion‑won hyperscale projects on its own. Its 270 MW “Gak Sejong” data center is optimized for its own search and LLM services, not for hosting global hyperscalers. Therefore, Naver is poorly positioned relative to the SK‑led mega‑data‑center opportunity and is likely to underperform the theme.

AI data center re-rating potential 100%.
SK Group is building a vertically integrated 15 GW AI data center megaproject across Ulsan, Yongin, and Suncheon, mirroring Google's full-stack AI monetization model. SK Telecom is the listed vehicle leading this initiative via its subsidiary SK Hyper. The data center business can re-rate the stock from a traditional telecom P/E of 8–10x to an AI infrastructure P/E of 20–30x. In a conservative scenario (12x P/E) the stock could rise ~35%, in a base case (20x P/E) ~50%, and in an optimistic scenario (25x P/E) 100% to a target of 200,000 won. The project is phased: first 5 GW by 2029, 15 GW by 2035, with revenue starting from H2 2026. Institutional investors and pension funds are accumulating the stock.

ESS battery demand turns around SK Innovation.
The 15 GW AI data center buildout will create huge demand for ESS (energy storage) batteries to stabilize power. SK On, a subsidiary of SK Innovation, has been struggling with low utilization and losses because its pouch‑type batteries are less favored for EVs. However, ESS can use LFP chemistry in pouch form safely, giving SK On a new volume outlet. Data center‑driven ESS demand can boost utilization, cut losses, and turn around SK Innovation's beaten‑down stock price.

Data center build‑out benefits construction sector.
If one wants to invest in the AI data center theme, the Korean construction sector is the most direct play because the data centers must be physically built, requiring construction companies. The sector is currently deeply out of favor and offers a neglected way to participate in the upcoming data‑center capex wave.
