Anthropic made its S-1 filing public Monday morning, setting up a stock market debut. The AI company behind Claude plans to sell Class A shares on the Nasdaq Global Select Market under the ticker ANT. Goldman Sachs and Morgan Stanley are leading the deal. The company has not yet set how many shares it will sell or a price range.

The filing shows revenue of $16.29 billion in the first six months of 2026. That is up from $1.16 billion a year earlier, CNBC reported. The operating loss was $693 million, down from $2.1 billion a year earlier, TechCrunch reported.

The net loss was much larger, at $80.7 billion. The company says most of it reflects non-cash charges on convertible notes. Those charges grew as the company's value rose. So the net loss is mostly an accounting cost, not cash spent to run the business.

Anthropic also lists long-term compute deals that run for years with Amazon, Google, Microsoft, SpaceX and others. It had about $6.2 billion in debt, tied to convertible notes held by Amazon. The company warns in the filing that it "may not achieve or sustain profitability in the future."

The filing also lays out how the company will be run. A Long-Term Benefit Trust will elect most of the board through Class T stock. The trust was set up in 2023 to guard the company's public benefit mission. A Founder LLC made up of the seven co-founders will hold a Class F share with 50.1 percent of the vote. Anthropic says the setup is meant to protect its AI safety mission. Critics note that public shareholders would have little say over the company.

Anthropic first filed in secret with the SEC in June. The debut is widely expected around mid-November. Reported talk of the company's value is not in the filing.

What we know: Anthropic plans to list on the Nasdaq as ANT, with the figures above from its filing.
What we don't: How many shares it will sell, at what price, and when trading will begin.
