Anthropic Files for Landmark IPO, Aiming for Record $100 Billion Raise

Anthropic has officially initiated the process for what could become the largest initial public offering in history. The AI safety and research company publicly filed its S-1 registration statement with the U.S. Securities and Exchange Commission on Monday, October 26, 2026.

The company intends to list on the Nasdaq Global Select Market under the ticker symbol "ANT." While the filing did not disclose the number of shares or a price range, reports suggest the offering could raise as much as $100 billion, potentially surpassing SpaceX's $86 billion debut earlier this year.

The filing reveals a company experiencing explosive growth alongside significant financial complexity. Anthropic reported first-half 2026 revenue of $16.3 billion, a massive leap from $1.2 billion in the same period last year. The company also achieved a milestone in Q2, posting its first quarterly operating profit of $974 million. However, this was overshadowed by a net loss of $80.7 billion for the first half, driven primarily by non-cash accounting charges related to convertible bonds.

Investors are also weighing the company's massive future commitments. The S-1 disclosed roughly $417 to $542 billion in minimum payment obligations, largely for data centers and cloud services. The prospectus notably includes a warning about the "catastrophic or existential risks" advanced AI could pose to humanity.

The IPO is targeted for the week of November 16, 2026, following the U.S. midterm elections. Goldman Sachs and Morgan Stanley are leading the offering.

5. First-half 2026 revenue hit $16.3 billion, up dramatically from about $1.2 billion in the same period of 2025 (roughly 1,300%+ growth). Q2 alone generated $11.6 billion.

6. Net loss for the first half of 2026 was $80.7 billion, driven largely by non-cash accounting charges related to the fair value of convertible bonds and similar instruments. Operating loss narrowed to $693 million, and the company posted its first quarterly operating profit ($974 million) in Q2.
