Anthropic Files for IPO, Plans Nasdaq Listing Under 'ANT'

Anthropic filed to go public on Monday. The company behind the Claude AI models plans to list its Class A shares on the Nasdaq Global Select Market under the ticker ANT.

The filing does not set a share count or a price range. No shares can be sold until the Securities and Exchange Commission declares the registration effective. Both Anthropic and existing shareholders plan to sell shares, with Goldman Sachs and Morgan Stanley listed first among the underwriters.

The filing opens the company's books for the first time. Revenue reached $16.29 billion in the first six months of 2026, up from $1.16 billion in the same period a year earlier. Full-year revenue was $4.59 billion in 2025, up from $386 million in 2024 and $41 million in 2023.

The net loss for the first half of 2026 was $80.7 billion. Most of it was a $72.4 billion charge from changes in the fair value of convertible notes and similar instruments as the company's valuation rose. The operating loss for the period was $693 million.

Anthropic filed a confidential draft of the filing in June. In May, it raised $65 billion at a $965 billion valuation. Reuters reported that some current and prospective investors are now valuing the company at about $1.5 trillion, down from roughly $2 trillion a week ago. Bloomberg has reported the listing could come as soon as mid-November.

Founders keep control

Public investors will be able to buy shares, but they will not control the company. An entity owned by Anthropic's seven co-founders will hold a single Class F share carrying 50.1 percent of shareholder voting power.

A Long-Term Benefit Trust will elect a majority of the board through a separate class of stock. Anthropic is a public benefit corporation, a form that requires it to balance profit with its stated purpose of developing advanced AI responsibly.

The filing also lays out the cost of running the business. Anthropic has agreed to spend up to $120.5 billion on computing from SpaceX through 2029, once all promised capacity is delivered. It warns that sustained profitability and continued rapid growth are uncertain, and that it depends on major cloud and chip companies for computing capacity.

The filing comes as investors question the debt-fueled spending on AI data centers, chips and computing capacity. Anthropic said the IPO would give it access to a deeper pool of capital to fund its AI ambitions.
