The public filing follows a confidential draft submitted to the SEC in June. Details of that draft reported by Reuters last month included backers' hopes for a valuation above $2 trillion. In May, Anthropic raised $65 billion at a $965 billion valuation.

Anthropic reported revenue of $16.29 billion for the six months ended June 30, 2026, compared with $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 company recorded a net loss of $80.7 billion for the first half of 2026. Most of that came from a $72.4 billion charge for changes in the fair value of convertible notes and other instruments, which the filing says was primarily driven by an increase in its valuation. Its operating loss for the period was $693 million.

As of June 30, 2026, Anthropic had raised $141.1 billion in total and held $112.4 billion in cash and cash equivalents, plus $19.3 billion in short-term investments, according to the filing. As of September 30, it had more than 1,900 customers generating at least $1 million in revenue over the previous 12 months, and about 250 generating at least $10 million.

Anthropic's governance structure

Anthropic is incorporated as a public benefit corporation, which requires its directors to balance shareholders' financial interests with those affected by its conduct and its stated purpose: "the responsible development and maintenance of advanced AI for the long-term benefit of humanity."

Under the proposed structure, the Long-Term Benefit Trust, a body of five financially disinterested trustees, will elect a majority of the board through a special class of stock. Immediately before the offering, Anthropic will issue a single Class F share to an entity owned by its seven co-founders, carrying 50.1% of the voting power on most shareholder matters. The filing says that makes Anthropic a "controlled company" under Nasdaq rules.

Holders of Class A shares will get one vote per share. The filing warns that the structure "may effectively eliminate the ability of holders of our Class A common stock to influence important decisions, including a change in control."

Anthropic has also contributed about 847 million non-voting shares, representing 5% of its fully diluted shares as of June 30, to a wholly owned subsidiary dedicated to its public benefit purpose. Its co-founders have each pledged to give 80% of their personal equity in the company to philanthropic causes, according to the filing.

The company announced the fund earlier this month, drawing criticism from investor and former White House AI czar David Sacks. "Whether it serves the public good remains to be seen," he tweeted.
