SAN FRANCISCO — Class A shares in Anthropic are headed for a public sale. On Monday the company told investors the registration statement — Form S-1 — was now on file with the U.S. Securities and Exchange Commission.
It wants those shares listed on the Nasdaq Global Select Market, under the ticker “ANT,” its announcement said. The announcement gave no share count and no price range.
The filing itself puts hard numbers on a business that has grown very fast. Revenue in the filing totals $16.29 billion for the six months to June 30, 2026 — a business that, in the same months of 2025, took in $1.16 billion.
The loss was $80.7 billion for the first half of 2026. Most of it — $72.4 billion — was a charge tied to changes in the fair value of convertible notes and other instruments, driven mainly by the rise in the company’s valuation, the filing says. Strip out that charge and the operating loss was $693 million.
Three years ago revenue was $41 million. It reached $386 million in 2024 and $4.59 billion last year.
Markets moved up on the news. Tech shares traded higher on Monday, with the Nasdaq Composite gaining 0.9% in recent trading, the S&P 500 up 0.7% and the Dow up 0.2% — a move Investopedia linked in part to the Anthropic filing.
Anthropic is not a conventional corporation. It is a public benefit corporation, so its directors must weigh shareholder returns against its stated purpose — the responsible development and maintenance of advanced AI for the long-term benefit of humanity.
Control will not sit with ordinary shareholders. A Long-Term Benefit Trust will elect a majority of the board through a special class of stock, the filing says. An entity owned by the company’s seven co-founders will hold a single Class F share carrying 50.1% of the voting power on most matters put to stockholders. That makes Anthropic a “controlled company” under Nasdaq rules, and holders of Class A shares get one vote per share.
The Times reported that the prospectus also warns advanced AI could pose “catastrophic or existential risks to humanity” if it fell into the wrong hands.
Monday’s filing was not the first step. Anthropic submitted a confidential draft to the SEC in June. In May, it raised $65 billion at a $965 billion valuation.
Goldman Sachs and Morgan Stanley are named first among the underwriters. Both Anthropic and existing shareholders will sell shares in the offering.
None of the shares can be sold yet. Anthropic said the registration statement has been filed but has not become effective, and that Monday’s announcement is not an offer to sell the securities.
