Following weeks of leaks regarding its S-1 filing, Anthropic officially submitted its application for an initial public offering (IPO) on Monday, setting the stage for one of the most highly anticipated IPOs in modern U.S. history.
According to the company’s latest filing with the U.S. Securities and Exchange Commission (SEC), Anthropic—which plans to list under the ticker symbol “ANT”—reported revenue of $16.3 billion for the first half of 2026, up from $1.2 billion in the same period the previous year.
This revenue growth was accompanied by an operating loss of $693 million—an improvement over the $2.1 billion operating loss recorded in the first half of 2025. However, the company’s net loss reached $80.7 billion, largely due to non-cash accounting adjustments related to convertible notes. Anthropic noted that it “may not be able to achieve or maintain profitability in the future.”
The filing also sheds light on the scale of Anthropic’s enterprise business. As of the end of September, the company had over 11,900 customers spending $100,000 or more annually; 1,900 customers spending $1 million or more; and approximately 250 customers spending $10 million or more per year.
As previously reported, Anthropic’s governance structure ensures that its seven co-founders will retain control of the company following its public listing. Dario Amodei, Daniela Amodei, Tom Brown, Jack Clark, Jared Kaplan, Sam McCandlish, and Christopher Olah will form a “Founder LLC,” which will collectively hold 50.1% of the shareholder voting power—a move Anthropic states is intended to safeguard the company’s mission regarding AI safety.
Additionally, the “Long-Term Benefit Trust”—established in 2023 to ensure the company upholds its public benefit mission—will have the authority to appoint a majority of the members of the company’s board of directors.
This governance structure has proven controversial, as it creates a disproportionate gap between voting power and the founders’ economic ownership. Consequently, public shareholders will have virtually no meaningful control over a company that itself acknowledges it is developing technology capable of posing “catastrophic or existential risks to humanity.” Anthropic has not yet disclosed how much capital it hopes to raise, nor has it revealed its proposed share price.
