Anthropic IPO: ANT Ticker, Revenue and Founder Control

TL;DR: Anthropic filed its S-1 on October 26 and plans to trade as ANT. The filing shows $16.3 billion in first-half 2026 revenue, an $80.7 billion net loss that is mostly an accounting charge, and a share structure that keeps 50.1% of the vote with its founders. No price or date is set.

Anthropic, the company behind the Claude AI models, filed its S-1 registration statement on Monday, October 26, according to The Wall Street Journal, and plans to trade under the ticker "ANT." It is the first official look at the company's books and ownership. If you hold public-market positions and are being asked about a listing this size, these are the numbers worth knowing before the roadshow starts.

What did Anthropic's S-1 show?

Growth, mostly. Anthropic reported $16.3 billion in revenue for the first half of 2026, up from $1.2 billion a year earlier, according to The Batch from DeepLearning.AI. The same report says the second quarter produced a $974 million operating profit on $11.6 billion in revenue, the first operating profit in any period the filing covers.

The loss line looks worse than it is. Anthropic recorded a net loss of $80.7 billion for the six months through June 2026, according to Yahoo Finance. Of that, $72.4 billion came from an accounting charge reflecting the higher value of convertible notes the company issued. Operating losses were $693 million, against $2.1 billion in the same period of 2025.

That gap matters. If you read the loss as cash burned, you will misjudge the company by a wide margin, because a charge tied to the rising value of notes is a bookkeeping result and not money spent on operations.

The company also reports an adjusted figure. Excluding stock-based compensation, non-cash charitable contributions and legal settlement expenses, Anthropic said it made $1.6 billion in operating income, about a 10% margin. That is the company's own framing. Weigh it against the unadjusted operating loss above.

Who controls Anthropic after the IPO?

The founders do. A single share held by a company owned by Anthropic's seven co-founders, including CEO Dario Amodei, carries 50.1 percent of the vote on most matters, and that voting power stays at 50.1 percent even if Anthropic issues more stock, according to The Batch. Yahoo Finance describes the same arrangement as power firmly concentrated in the hands of the seven cofounders through a multi-class share structure.

You would own the economics without a say. On most matters the founders decide the vote however many shares you hold, and some investors accept that trade for a company they believe in. You should know you are making it.

What is still unknown about the valuation and date?

Most of what investors want to know is not in the filing. The WSJ notes Anthropic did not reveal the valuation it is targeting or the number of shares it plans to sell. Its latest filing, dated November 2, still has no price range, according to Nacionale. A price range in a new S-1/A is the clearest public sign the debut is days away.

Timing rests on reports, not filings. The Batch says Anthropic could go public as soon as the week before Thanksgiving and hopes to sell roughly $100 billion in shares, per The Wall Street Journal. On valuation, Yahoo Finance says media reports have the company targeting somewhere between $1.5 trillion and $2 trillion. Treat those as reported targets. The company has published neither one.

Common mistakes

The first mistake is reading the $80.7 billion loss as cash out the door. Most of it is a non-cash charge, as the table shows. The second is treating a reported valuation range as a price you can buy at, when nothing is priced and the shares cannot be sold until the SEC declares the registration effective, as Nacionale explains.

The third is assuming you can get in at the IPO price. Whether a listing happens and whether an individual investor can get shares at the offer price are separate questions.

What to watch next

Watch EDGAR for the next S-1/A with a price range and share count. Then read the risk factors and the share-class terms before you read any valuation commentary.

FAQ

Is the Anthropic IPO worth buying?

No source here can answer that, and nothing in this article is a recommendation. The price is not set, and founders keep 50.1% of the vote. Those two facts, plus the unadjusted operating loss, are what you would weigh against whatever range is eventually published.

Is Anthropic still going to IPO in 2026?

Reports point to a November listing, most likely the week before Thanksgiving, per Nacionale. No date is official.

How much is Anthropic expected to raise in its IPO?

The Batch, citing The Wall Street Journal, says Anthropic hopes to sell roughly $100 billion in shares. The S-1 does not state the share count, so treat the figure as a reported target.
