Anthropic Files S-1 for Public Offering
Original: Anthropic S-1
Why This Matters
One of the most-funded private AI companies is now on a public market path.
Anthropic, PBC filed an S-1 registration statement with the SEC on October 26, 2026, signaling an IPO. The AI safety company, led by Dario and Daniela Amodei, is incorporated in Delaware and headquartered in San Francisco.
Anthropic, PBC — the AI safety company co-founded by Dario Amodei (CEO) and Daniela Amodei (President) — filed a Form S-1 registration statement with the U.S. Securities and Exchange Commission on October 26, 2026, the first formal step toward a public offering. The company is registered as a Delaware public benefit corporation, with principal offices at 548 Market Street, San Francisco. Its IRS employer ID is 86-1696045, and it is classified under SIC code 7372 (Prepackaged Software). Wilson Sonsini Goodrich & Rosati is serving as outside counsel, alongside Freshfields US LLP. The filing is a non-accelerated filer, meaning Anthropic does not yet qualify as a large or accelerated filer under SEC definitions. The registration statement will become effective after any required amendments are filed and approved. No offering price or share count is disclosed in this initial filing, which is standard for S-1 submissions at this stage.
