Anthropic releases IPO filing ahead of highly-anticipated stock debut
The filing details rapid revenue growth, $80.7 million in first-half losses and more than 90 pages of AI safety and business risks.
- 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."
- Anthropic's valuation soared from $183 billion last year to $965 billion in May, driving the company to seek public capital for massive infrastructure investments required to sustain rapid growth.
- The filing discloses $16.3 billion in revenue for the first half of 2026, though roughly $72 billion of the $80.7 billion net loss stems from non-cash accounting adjustments related to convertible notes.
- Market analysts suggest the offering could raise as much as $100 billion and value Anthropic at up to $2 trillion, potentially eclipsing SpaceX's June IPO record of $85.7 billion raised.
- 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.
