Anthropic reportedly filed for an initial public offering with the U.S. Securities and Exchange Commission on Monday, and Seoul felt it first. The Korea Herald reported on October 27, 2026 that the filing puts Korean tech firms’ early bets on the Claude maker in the spotlight, from SK Telecom‘s 2023 check to fresh trillion-won commitments from Samsung Electronics and SK hynix.
The Anthropic IPO is slated for Nasdaq under the ticker ANT, according to Investinglive. Reports on the filing name Goldman Sachs and Morgan Stanley as the banks leading the offering. No trading date has been announced, and the biggest numbers floating around (a $2 trillion valuation, a raise above $100 billion) remain unconfirmed.
This piece stays on the Korean side of the story. It covers who owns what, how the paper gains look, what the local market did, and where the risks sit. For the filing’s own financials, read our earlier breakdown of the Anthropic S-1.

What Anthropic Reportedly Filed on Monday
The core facts are short. Anthropic filed with the SEC on Monday, per reports dated October 27, 2026. The company plans a Nasdaq listing under ANT. Goldman Sachs and Morgan Stanley lead the deal. That is the full list of confirmed items, and everything else in the coverage so far falls into a looser category.
The looser category includes a reported target date of November 16, 2026, a planned raise above $100 billion, and a valuation range of $1.5 trillion to $2.0 trillion. One report presented a $2 trillion valuation as a scenario, not a number the company has stated. We treat all of these as unconfirmed until Anthropic’s public filing or an official announcement says otherwise.
Why does the distinction matter for Korea? Because the headline gains that Korean investors might book depend on the final price, and that price does not exist yet. Our look at how the offering stacks up against the biggest listings covers the size debate. Here, the focus is the shareholders who bought in years before any ticker existed.
Which Korean Companies Hold Anthropic Stakes
Four Korean groups show up in the Korea Herald’s reporting: SK Telecom, Naver, LG CNS, and the pair of Samsung Electronics and SK hynix. They arrived at different times, through different vehicles, and with very different check sizes. The table below pulls the disclosed details into one place.
| Korean investor | Vehicle | When | Reported amount | Stated plan |
|---|---|---|---|---|
| SK Telecom Co. | Direct | August 2023 | $100 million at a $5 billion valuation | Intends to keep the stake |
| SK Telecom Co. (top-up) | Direct | First half of 2026 | 157,189 shares for about $100 million | Intends to keep the stake |
| Naver | Naver Ventures | Second half of 2025 | About 10 billion won | Not stated in the report |
| LG CNS | LG Technology Ventures | 2023 | Amount not disclosed in the reports reviewed | Not stated in the report |
| Samsung Electronics | Not specified | May 2026 | At least 1 trillion won | Not stated in the report |
| SK hynix | Not specified | May 2026 | At least 1 trillion won | Not stated in the report |
Read the table by timing. The 2023 buyers (SK Telecom and LG CNS) entered when the startup carried a $5 billion price tag in SK Telecom’s case. The 2025 buyer (Naver) came in with a small, venture-arm check. The 2026 buyers (Samsung Electronics and SK hynix) put in at least 1 trillion won apiece only about five months before the filing. Those last two are the ones most exposed to whatever price the market sets, because they bought closest to it.
SK Telecom: From a $100 Million Check to a $2.65 Billion Book Value
SK Telecom is the cleanest case study because the Korea Herald gave actual numbers on both ends. The carrier put $100 million into Anthropic in August 2023. At the end of June 2026, the book value of its Anthropic holdings stood at 3.51 trillion won ($2.65 billion), up from 1.38 trillion won at the end of 2025.
The 2023 entry point
When SK Telecom wrote that first check, Anthropic was valued at $5 billion. Simple division puts the stake at roughly 2 percent at entry, before any dilution from later funding rounds. We cannot compute today’s ownership percentage because no source in our reporting gives it. Dilution across several rounds almost certainly shrank that 2 percent, but by how much remains unknown.
The 2026 top-up
In the first half of 2026, SK Telecom bought another 157,189 shares for approximately $100 million. Dividing one number by the other gives about $636 per share, which is our arithmetic and not a figure any outlet reported. The comparison to the 2023 entry is still useful. SK Telecom doubled its cash outlay, and it did so at a price far above the one it first paid.
| Metric | Figure | Basis |
|---|---|---|
| Book value, end of 2025 | 1.38 trillion won | Reported by the Korea Herald |
| Book value, end of June 2026 | 3.51 trillion won ($2.65 billion) | Reported by the Korea Herald |
| Change in six months | Up 2.13 trillion won, about 2.5x | Our arithmetic |
| Implied exchange rate | About 1,324 won per dollar | Our arithmetic from the two reported figures |
| Per-share price of 2026 top-up | About $636 | Our arithmetic (about $100 million divided by 157,189 shares) |
| Total outlay if only two tranches | About $200 million | Assumption, the reports do not confirm there were no others |
| Book value vs. that outlay | Roughly 13x | Our arithmetic, conditional on the assumption above |
Book value is an accounting mark. It reflects how SK Telecom values the shares on its balance sheet, not cash in hand. The jump from 1.38 trillion won to 3.51 trillion won in six months tells us the carrier marked the position up sharply, and part of that rise came from the extra shares it bought. It does not tell us what the market will pay on a listing day.
Samsung Electronics and SK hynix: The Trillion-Won Chip Bets
The Korea Herald reported that Samsung Electronics and SK hynix each invested at least 1 trillion won in Anthropic in May 2026. At the exchange rate implied by SK Telecom’s own figures, 1 trillion won comes to about $755 million, so each chipmaker’s reported floor is several times SK Telecom’s original 2023 check.
The logic for chipmakers differs from a carrier’s. SK Telecom positions itself as an AI infrastructure partner. Memory and logic makers, by contrast, sell the silicon that frontier labs consume in volume. A stake in a lab that may keep buying more compute works as a hedge on their own order books. If Anthropic raises fresh capital in a listing, a share of that money can eventually flow back into hardware demand.
That link is why Korean equity desks moved fast. KED Global reported that the Kospi jumped as Samsung and SK Hynix rallied on the Anthropic IPO plan and hopes for payouts. The market read the filing as good news for AI spending and for the chipmakers’ own balance sheets at once.
Neither company’s exact stake size, ownership percentage, or accounting treatment appears in the reports we reviewed. Until the two firms disclose more, the 1 trillion won floor is the only hard number.
Naver and LG CNS: The Smaller, Earlier Positions
Naver invested approximately 10 billion won in Anthropic through Naver Ventures in the second half of 2025, according to the Korea Herald. At the implied exchange rate that is about $7.6 million, small next to the chipmakers’ May 2026 commitments. Naver ran its bet through a venture arm and not the parent balance sheet, which can signal a financial and strategic-option play over a core partnership.
LG CNS invested through LG Technology Ventures in 2023, the same year as SK Telecom. The report does not give an amount in the material we reviewed, so we will not guess one. What we can say is that a 2023 entry sits at the early end of the timeline, well before the 2026 valuation surge. If any Korean investor holds a low cost basis relative to the eventual listing price, LG CNS belongs on that shortlist.
Both firms show a pattern worth watching. Korean corporate venture arms bought into a foreign AI lab early, and only now is the wider market noticing. Expect analysts to ask both companies how large their holdings are and whether they plan to sell.
Confirmed vs. Unconfirmed: Sorting the IPO Numbers
News cycles around giant listings tend to blur reported figures and confirmed ones. The table below separates what the sources support from what they present as scenarios or leaks.
| Claim | Status | What the reporting says |
|---|---|---|
| Anthropic filed with the SEC on Monday | Reported | Reports dated October 27, 2026 |
| Nasdaq listing under ticker ANT | Reported | Investinglive and other outlets |
| Goldman Sachs and Morgan Stanley lead | Reported | Reports on the filing |
| $2 trillion valuation | Unconfirmed | Presented as a scenario, not a stated valuation |
| $1.5 trillion to $2.0 trillion range | Unconfirmed | Appears in one report |
| Raise above $100 billion | Unconfirmed | Appears in one report |
| Target date of November 16, 2026 | Unconfirmed | Appears in one report |
| Trading starts in November 2026 | Unconfirmed | The report says no trading date was announced |
The $2 trillion figure deserves the most caution. It circulated as a what-if, and a what-if can still move a stock. Korean shares reacted to the possibility long before any underwriter set a price range. Readers who track Korean holdings should keep those two things apart in their own notes.
How Korean Markets Reacted on October 27
The reaction came within hours. Aju Press ran a headline saying the KOSPI surged more than 4 percent on Anthropic’s IPO filing. MoneyToday described a volatile KOSPI battling around the 5,700 mark as Anthropic IPO hopes fueled chip stocks. Those two descriptions fit together: a sharp morning jump followed by choppy trading.
Volatility was already the story before the filing. Our earlier note on how the Kospi opened lower as chip stocks split shows how quickly sentiment on these stocks flips. One filing did not remove that fragility. It added a new catalyst to a market that already trades hard on AI headlines.
Look at who gained. Samsung and SK hynix carry direct exposure through their May 2026 stakes and indirect exposure through hardware demand. SK Telecom carries the largest disclosed stake. A rally across all three on the same day suggests investors priced in both channels. Whether that holds after the first wave of profit-taking is a separate question.
What Verified Voices Say
Several statements from SK Telecom’s side help explain how the carrier thinks about the position. Chosun’s English edition, in an article dated June 10, 2026, quoted CEO Jung Jai-hun on why the company followed up on its first investment.
As an early investor, we were given the opportunity to participate in the follow-up investment.
Jung Jai-hun, CEO, SK Telecom, via Chosun’s English edition (June 10, 2026)
That line confirms the top-up came as an invitation tied to SK Telecom’s early-investor status, not an open-market purchase. Jung also addressed the question every shareholder asks about a big listing, which is whether the carrier plans to cash out.
We judged that continuing the investment would be beneficial, as our plan is to maintain a cooperative relationship rather than focus on profits from Anthropic’s potential initial public offering (IPO) success.
Jung Jai-hun, CEO, SK Telecom, via Chosun’s English edition (June 10, 2026)
Currently, SK Telecom has no financial difficulties, and since there are areas where we can continue to collaborate with Anthropic, we have no immediate plans to sell our stake.
Jung Jai-hun, CEO, SK Telecom, via Chosun’s English edition (June 10, 2026)
Taken together, the two Jung statements frame the stake as a partnership asset and not a trade. The Korea Herald’s coverage of the IPO reports the same intent to hold. A company spokesperson added a line about the carrier’s wider ambition.
We will continue to strengthen our role in the global AI ecosystem as an AI infrastructure company through our partnership with Anthropic.
SK Telecom company spokesperson, via the Korea Herald
The pattern across all four statements is consistent. SK Telecom talks about collaboration and infrastructure and avoids talking about exit timing. That stance can change if the share price moves far enough, but for now the company’s public position is to hold.
Competitive Comparison: Four Korean Playbooks
Korean investors did not approach Anthropic the same way. Comparing the four approaches shows what each firm was likely trying to achieve, based on the disclosed facts and our own reading of them.
SK Telecom, the strategic partner. It went in early, doubled down in 2026, and says it will hold. Its stake is large enough to move its own accounts. Its upside is clearest, and so is its concentration risk, since a single holding now carries a book value of 3.51 trillion won.
Samsung Electronics and SK hynix, the supply-chain hedgers. Their May 2026 stakes of at least 1 trillion won each came late and large. They are buying exposure to a major customer segment. If Anthropic’s compute appetite keeps growing, their core business benefits regardless of the listing price.
Naver, the venture-arm explorer. Its roughly 10 billion won came through Naver Ventures in late 2025. That is a modest stake relative to the others and fits a portfolio approach more than a partnership.
LG CNS, the early quiet holder. It entered in 2023 through LG Technology Ventures. With no disclosed amount, it is the hardest to assess, but the timing alone places it among the earliest Korean backers.
Anthropic’s cloud relationships add context here. Our report on how Anthropic draws a large share of sales through three cloud marketplaces shows that the company already depends on a few big infrastructure partners. Korean carriers and chipmakers sit one step further back in that chain, as capital providers and component suppliers.
Historical Context: From 2023 Checks to a Nasdaq Ticker
The Korean timeline tells its own story. In 2023, SK Telecom and LG CNS bought in while Anthropic carried a $5 billion valuation. In the second half of 2025, Naver followed with a venture-arm check. By the end of 2025, SK Telecom’s holdings were marked at 1.38 trillion won. In the first half of 2026, SK Telecom added more shares. In May 2026, Samsung Electronics and SK hynix each committed at least 1 trillion won. In late October 2026, the filing arrived.
Read as a sequence, the stakes grew in size as the company’s perceived value grew. Early checks were modest, and later ones were far larger. That is the standard shape of a hot private round, where each new investor pays more than the last. The danger sits at the end of the sequence. The latest and largest buyers hold the thinnest cushion if a listing prices below private marks.
The Korean group list is also unusually broad. A carrier, two chipmakers, a search-and-platform company, and an IT services arm now appear on the same foreign AI lab’s reported shareholder list, which is a wider mix than a single-sector bet.
Market Impact for Investors and AI Infrastructure
For retail investors in Korea, the filing creates a new kind of proxy trade. Buying SK Telecom, Samsung Electronics, or SK hynix now means buying a slice of Anthropic exposure along with the core business. That makes each stock sensitive to Anthropic’s pricing, its first-day trading, and any delay. A postponement could hit these shares as hard as a successful debut could lift them.
For the AI sector, a Nasdaq listing by a leading lab would give the market its first public price for a standalone frontier-model company of this kind. Analysts would gain a benchmark to compare with other AI names. Korean chipmakers gain a signal about how much capital the sector can raise for compute.
Risks sit on the other side. The unconfirmed valuation and raise figures could change a lot before pricing. The timeline is unannounced. And the Korean rally on October 27 priced in hope, not a finished prospectus. Investors should read the public filing text themselves and not rely on a secondhand summary, including this one.
Five Predictions for the Weeks Ahead
These are our own forecasts based on the facts above, and none comes from a named source. Treat them as informed judgment, not reported fact.
- SK Telecom holds through any lockup period. Its CEO has framed the stake as a partnership, and the company says it has no immediate plans to sell. We expect that stance to survive at least the first months after listing.
- Korean chip stocks stay jumpy. The October 27 swings suggest every pricing leak or delay report will move Samsung Electronics and SK hynix. Expect further sharp days around each new headline.
- Disclosure pressure rises on Samsung Electronics, SK hynix, and LG CNS. Analysts will want exact stake sizes and accounting treatment, and the companies will face questions in their next earnings communications.
- The valuation debate narrows before pricing. The $1.5 trillion to $2.0 trillion range and the $2 trillion scenario will likely give way to a formal price range once underwriters publish one.
- More Korean firms come forward. Other Korean funds and corporate venture arms may disclose Anthropic exposure now that attention has arrived, which would widen the list beyond the four groups reported today.
Why the Claude Models Race Matters Here
A listing is only as strong as the product behind it. Anthropic’s current lineup sits in the Claude 5.5 generation, and our model comparison of GPT-6.1 Sol, Sonnet 5.5, and Gemini 4 Argon shows how crowded the field has become. Korean investors are betting that Claude keeps its place near the top.
That bet connects the carrier, the chipmakers, and the venture arms. Each wants usage to grow, since usage drives compute demand, partnership revenue, and eventually the share price. If a rival model takes the lead, the Korean marks could come under pressure whatever the IPO calendar says. Readers following the wider sector can find more in our AI and machine learning coverage.
