What happened
Anthropic filed an S‑1 with the SEC on Oct. 26, 2026, seeking to raise about $100 billion. Startup Fortune cites reporting from PYMNTS and Nasdaq that bankers are eyeing a valuation near $2 trillion – roughly half of South Korea’s KOSPI market cap of $3.5 trillion. The article notes that the KOSPI rose 3 % the day after the filing became public, driven by gains in Samsung Electronics and SK Hynix as investors anticipated continued AI‑related chip demand. Anthropic’s recent financing history includes a $30 billion Series G round in Feb. 2026 at a $380 billion valuation and a $65 billion Series H round in May at $965 billion, according to Bloomberg Law. Its S‑1 shows $19.7 billion in revenue, a $109.74 billion net loss, $2.5 billion in annualized recurring revenue from Claude Code, and $19 billion in spend for the year ended June 30, 2026. Goldman Sachs, JPMorgan and Morgan Stanley are leading the underwriting, with pricing expected within three weeks of the filing.
On Oct. 26, 2026 Anthropic submitted an S‑1 registration statement to the U.S. Securities and Exchange Commission, indicating an intention to list on the Nasdaq under the ticker "ANT." The filing disclosed plans to raise roughly $100 billion, a figure that would support a post‑money valuation near $2 trillion, according to sources cited by Startup Fortune (PYMNTS, Nasdaq).
The article places the rumored valuation alongside South Korea’s KOSPI index, which the Korea Herald reported at about 4,979 trillion won ($3.5 trillion). Half of that market cap would be covered by Anthropic’s potential valuation, a comparison that resonated with Korean investors and contributed to a 3.09 % gain in the KOSPI on Oct. 27.
Anthropic’s recent financing rounds are detailed: a $30 billion Series G round in February 2026 at a $380 billion valuation, followed by a $65 billion Series H round in May at $965 billion. The S‑1 filing shows $19.7 billion in revenue for the twelve months ended June 30, 2026, a net loss of $109.74 billion, $2.5 billion in annualized recurring revenue from its Claude Code product, and $19 billion in spend.
Goldman Sachs, JPMorgan, and Morgan Stanley are leading the underwriting team, with Wilson Sonsini as legal counsel. The underwriters expect to set a price within about three weeks of the filing, a relatively fast timeline for a deal of this magnitude.

Why it matters
If Anthropic’s valuation reaches $2 trillion, it would become the largest IPO ever, surpassing SpaceX’s $1.77 trillion listing. Such a valuation would signal that public markets are willing to price AI labs far beyond traditional cash‑flow metrics, reinforcing the narrative that AI infrastructure is a strategic asset for the broader tech ecosystem. The comparison to South Korea’s KOSPI underscores the scale of capital being funneled into AI, potentially influencing sovereign wealth funds, chip manufacturers, and policy makers who view AI as a national priority. At the same time, the massive loss figures and spend highlight the sustainability challenges of AI‑heavy business models, raising questions about how long investors will tolerate such deficits. The market reaction—KOSPI’s 3 % jump—illustrates that the filing is already shaping sentiment toward AI‑related equities, especially semiconductor stocks that stand to benefit from increased AI spend. However, the $2 trillion figure remains a rumor; the final pricing could be lower, and the IPO’s success will depend on post‑listing performance, regulatory scrutiny, and broader macro‑economic conditions.
A $2 trillion valuation would make Anthropic the most valuable public company ever, eclipsing SpaceX’s $1.77 trillion market cap. This would cement AI labs as a distinct asset class, potentially attracting more institutional capital to the sector and influencing how investors assess risk versus growth in AI‑centric businesses.
The valuation comparison to South Korea’s entire stock market highlights the sheer scale of capital being allocated to AI, which could affect national economic strategies. Korean policymakers and investors may view the filing as a catalyst for further AI investment, especially in semiconductor manufacturing, which underpins AI .
Anthropic’s financials reveal a business model that is heavily loss‑driven, with spend approaching its revenue. The market’s willingness to price such a loss‑making company at $2 trillion raises questions about the durability of this optimism, especially if macro‑economic conditions tighten or AI spending slows.
The immediate market reaction—KOSPI’s 3 % rise—shows that the filing is already influencing equity sentiment, particularly for chipmakers that stand to benefit from AI demand. This could lead to a feedback loop where AI‑related stocks rally on the expectation of continued AI spend, further inflating valuations.

What to watch next
Key variables to monitor include the final IPO price and market cap once Anthropic lists under the ticker ANT, the reaction of Korean and other Asian equity markets to the valuation, and any regulatory or antitrust reviews that could affect the offering. Investors should also watch Anthropic’s ability to narrow its loss margin as it scales Claude and other models, and whether chip makers such as Samsung and SK Hynix see a sustained uptick in AI‑related orders. Finally, the broader AI IPO landscape—particularly any filings from competitors—will indicate whether Anthropic’s valuation is an outlier or the new for AI‑centric public companies.
