- Anthropic filed for an IPO on October 26, 2026, planning to list under the ticker “ANT.”
- The company reported $16.3 billion in first-half 2026 revenue, up from $1.2 billion a year earlier.
- Anthropic‘s net loss reached $80.7 billion, driven largely by noncash accounting charges tied to convertible debt.
- A “Founder LLC” made up of Anthropic‘s seven co-founders will control 50.1% of shareholder voting power after the listing.
What Happened
Anthropic filed its S-1 registration with the SEC on Monday, October 26, 2026, confirming plans for an initial public offering under the ticker “ANT,” TechCrunch reported. The filing follows weeks of leaked draft S-1s that had previewed the company’s financials ahead of the official filing.
Why It Matters
The filing formalizes a process Anthropic had been preparing for months. In August 2026 the company was already reported to be preparing an IPO that could rival SpaceX’s record debut, and in June 2026 it had confidentially filed paperwork ahead of OpenAI’s own IPO process. The public filing now puts Anthropic’s full financials and governance structure on the record for the first time.
Technical Details
Anthropic recorded $16.3 billion in revenue for the first half of 2026, up from $1.2 billion in the same period last year, while its operating loss narrowed to $693 million from $2.1 billion a year earlier. The company’s net loss hit $80.7 billion, which it attributed largely to noncash accounting adjustments tied to convertible debt. As of the end of September, Anthropic counted more than 11,900 customers spending $100,000 or more annually, 1,900 spending $1 million or more, and about 250 spending $10 million or more.
Who’s Affected
The filing gives the most detail yet on Anthropic’s seven co-founders — Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish, and Christopher Olah — who will form a “Founder LLC” controlling 50.1% of shareholder voting power after the IPO. Public shareholders will have limited practical control over the company, since voting power won’t be proportional to economic ownership, and Anthropic’s Long-Term Benefit Trust will retain authority to appoint most of the board.
What’s Next
Anthropic has not yet disclosed how much it intends to raise or its proposed share price. The company said in its filing that it “may not achieve or sustain profitability in the future,” leaving the scale and timing of the actual offering still undetermined.
