Shares of SK Telecom (SKM) spiked 9.6% in pre-market trading to $35.32 on August 7, extending a volatile stretch that has seen the stock swing from $29.64 to $35.32 in barely a week — a 19% range — with no new earnings data or strategic announcements to justify the moves. For shareholders, the question is whether this trader-driven momentum is building a floor or setting a trap. SK Telecom's Pre-Market Fever Meets Real Earnings — Is the AI Data Center Pivot Enough to Justify the Ride?
Shares of SK Telecom surged 9.6% to $35.32 in pre-market on August 7, extending a wild week that saw the stock swing across a 19% range from $29.64 to $35.32 with no fresh catalyst this morning. But what traders betting on momentum may not yet have priced in: the company just reported genuinely strong Q2 numbers two days ago, raising the question of whether speculative froth is now sitting on top of a legitimate business inflection.
• A 67% Profit Jump Looks Huge, but a Cybersecurity Hangover Flatters the Numbers
SK Telecom's Q2 operating profit soared 67.3% year-over-year to KRW 566 billion (~$397 million), driven by AI data center momentum. However, the headline profit jump was "flattered by a low base" — one-off expenses from a 2025 cybersecurity incident inflated last year's costs, making this year's comparison look better than the underlying trend.
Consolidated revenue growth was a modest 0.5% year-over-year, indicating limited top-line expansion in the core telecom business. Shareholders should note the profit surge overstates organic improvement.
• The AI Data Center Bet Is Growing Fast — From a Tiny Base
AI data center revenue reached KRW 136.2 billion, up 92.5% from a year earlier. That's roughly $95 million — impressive growth, but still small relative to $3 billion in quarterly consolidated revenue. SK Telecom's new subsidiary, SK Hyper, plans to bring AI data centers online in phases targeting a combined capacity of 5 GW by 2029.
The company's strategy is customer-first — aiming to secure clients before construction and finance projects through external investors to minimize its direct investment burden. Execution risk is high; the payoff is years away.
• Speculative Trading Is Running Ahead of Fundamentals The stock has added roughly $3 per share in a week on no news beyond an earnings report that, while solid, was already public by August 5. Pre-market spikes of this magnitude in a telecom name with 0.5% revenue growth suggest short-term traders — not long-term investors — are driving the price. SK Telecom maintains a stable dividend of KRW 831 per share, balancing growth investments with shareholder returns , which should anchor valuation over time but does nothing to justify day-to-day double-digit moves.
• The Real Test Is Whether AI Revenue Can Outgrow the Hype
SK Telecom is positioning itself as an AI infrastructure leader through SK Hyper, targeting rapid data center expansion while maintaining financial discipline.
It also plans to build an AI data center in collaboration with OpenAI. The strategic vision is credible, but today's price action is momentum, not conviction. Until AI revenue becomes a material share of the top line, these spikes are borrowed time.
