IPO website gives the listing schedule

Anthropic pointed to a website for its initial public offering (IPO) through its official X account on Nov. 12 (the night of the same day Japan time). According to the website, the final offering price will be set on Nov. 19 (Japan time), subject to regulatory approval, and the shares are expected to begin trading on the Nasdaq market on Nov. 19 (U.S. time). The shares being offered are Class A shares, and the ticker symbol is "ANT."

Our initial public offering: https://t.co/wPZ1LteuQv Legal disclaimer: Anthropic has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration

The post was published at 8:30:46 p.m. Nov. 12 Japan time, and the text obtained through the official API ends partway through the legal disclaimer. The website carries a letter from the founders, a roadshow video divided into 11 chapters, financial highlights for the July-September quarter, customer case studies and the prospectus.

On Nov. 10, the company had announced it was starting a roadshow, in which it visits institutional investors to pitch its shares. The expected price and the number of shares to be offered were covered in a previous article, but the announcement and the amended registration statement at that time did not give a listing date. The website says the roadshow began on Nov. 11 (Japan time) and gives the subsequent schedule for the first time. The fact sheet says the offering price is "undetermined" and will be announced in U.S. dollars on Nov. 19 (Japan time).

6 firms to handle the offering in Japan

According to the fact sheet, Class A shares will also be offered in Japan. The application date is Nov. 19 (Japan time), and applications can be made in units of one share. The six firms handling the offering are Mizuho Securities, Goldman Sachs Japan, Mitsubishi UFJ Morgan Stanley Securities, Morgan Stanley MUFG Securities, Rakuten Securities and SBI Securities.

The company has filed a securities registration statement for the Japanese offering with the Kanto Local Finance Bureau, but like the U.S. registration statement, it has not yet become effective. According to the website, participating requires a brokerage account, and there is no guarantee that all shares applied for will be obtained. Exchange between yen and foreign currency will use rates set by each firm, and the method for setting terms differs from that of a typical pre-listing offering in Japan, it said.

July-September revenue about $17 billion; operating result swings back to a loss

According to the IPO website and fact sheet, revenue for the July-September quarter of 2026 was $16.956 billion, more than 12 times the $1.382 billion a year earlier. It also rose from $11.555 billion in April-June. The company put its annualized revenue (run-rate) as of October at about $81 billion. The number of customers that paid $100,000 or more over the past 12 months exceeded 11,900.

Meanwhile, the operating result was a loss of $567 million (an operating margin of minus 3%), swinging back from an operating profit of $974 million in April-June. The adjusted operating margin, which excludes items such as $1.07 billion in stock-based compensation and $1.96 billion in non-cash charitable contributions, was 15%, down from 19% in April-June. The net loss was $23.291 billion, of which $21.936 billion was a non-cash expense from revaluing convertible notes and other instruments as the company's valuation rose.

Compute and infrastructure costs were $9.863 billion, up from $5.558 billion in April-June. The ratio of revenue to these costs fell from 2.08 times to 1.72 times. The company said the addition of compute, including $5 billion under short-term commitments, partly offset improvements in efficiency, and that this compute is significantly more expensive than comparable compute procured under multi-year commitments. As of the end of September, compute commitments totaled about $900 billion, cash and cash equivalents about $96 billion and short-term investments about $36 billion.

Anthropic's quarterly revenue and compute and infrastructure costs ($ billion; from the income statement in the company's IPO fact sheet)

The adjusted operating margin is the company's own measure, not based on U.S. generally accepted accounting principles (GAAP). It is calculated by excluding stock-based compensation, non-cash charitable contributions and the settlement cost of a copyright lawsuit (the Bartz lawsuit) from the operating result.
