Anthropic releases IPO filing ahead of highly-anticipated stock debut
- On Monday, October 26, 2026, Anthropic PBC filed its S-1 prospectus with the U.S. Securities and Exchange Commission to list common stock on the Nasdaq Global Select Market under the ticker "ANT."

- CEO Dario Amodei warns that advanced AI models pose "catastrophic or existential risks to humanity," yet Anthropic's governance structure ensures founders retain 50.1% of voting power over key corporate matters.
