SK Telecom's 9% Day Is a Bet on 0.3% of Anthropic

SK Telecom traded at 99,000 won by 10:45 a.m. on the 14th, up 8.67%, after touching 100,300 won intraday ^[1][2]. The trigger was not Korean: the Financial Times reported on the 12th, citing Anthropic investors, that the AI company could be valued at more than $2 trillion in an IPO process as early as this October ^[3].

That implies a prior close near 91,100 won, which makes the intraday high roughly a 10% move ^[4][5]. For a carrier whose telecom earnings are described by its own analysts as stable, that is a repricing of something other than telecom ^[6].

The something is a minority stake. SK Telecom put $100 million into Anthropic in 2023 for about 2%, which implies a valuation around $5 billion at the time ^[7][8]. A $2 trillion listing would be roughly 400 times that mark ^[9]. The catch is that the stake has been diluted to about 0.3% through new share issuances ^[7], including a Series H round last month that SK Telecom joined alongside Samsung Electronics and SK hynix ^[10]. At $2 trillion, 0.3% is about $6 billion, or roughly 60 times the original cheque ^[11][12]. That is a real number, and it is a number attached to a reported expectation among Anthropic's own investors rather than a priced deal. The FT report also puts the figure above the $1.77 trillion valuation of SpaceX, which listed in June ^[13].

Two domestic catalysts arrived in the same tape. The government's second-round evaluation of its sovereign AI foundation model project is due as early as next week, with SK Telecom pushing agent capability through its A.X K2 model ^[14]. Quantum technology's inclusion in the government's "7 Growth SEEDs" initiative added to sentiment ^[15].

The operating business is growing, though not quite in the shape the narrative suggests. Second-quarter operating profit rose 67.3% year on year to 566 billion won, ahead of expectations ^[16]. IDC revenue at SK Broadband rose 92.5% to 136.2 billion won ^[17]. Run the arithmetic: that revenue line grew by about 65 billion won, against an operating profit increase of about 228 billion won ^[18][19]. The data centre business is compounding fast off a small base; it is not yet what produced the profit beat.

NH Investment & Securities keeps a buy rating and a 115,000 won target, about 16% above the 99,000 won print, and frames the company as an AI infrastructure operator resting on stable telecom cash flow ^[6][20]. It points to a plan to invest 750 billion won, about $540 million, in data centre subsidiary SK Hyper, and to expand AI data centres to as much as 5 gigawatts ^[21]. Analyst Ahn Jae-min said the AI infrastructure expansion could be a trigger for a valuation re-rating ^[22].

What to watch: whether Anthropic or any bank confirms an October timetable, since the story currently rests on investors talking to one newspaper ^[3]; the second-round sovereign model result ^[14]; and the distance between 750 billion won of disclosed commitment and a 5 gigawatt ambition ^[21]. A listing would also convert an opaque private mark into a daily price, which cuts both ways for the holder of 0.3% ^[7].
