Anthropic Confidentially Files Draft S-1 With the SEC

Anthropic, PBC has confidentially submitted a draft registration statement on Form S-1 to the US Securities and Exchange Commission, the company said on June 1, 2026. The filing concerns a proposed initial public offering of its common stock and gives Anthropic the option to go public after the SEC completes its review.

What the company said

In its announcement, Anthropic stressed that the proposed offering would depend on market conditions and other factors, and that the number of shares to be offered and their price have not yet been set. The statement was published under Rule 135 of the Securities Act of 1933, as amended, which allows a company to announce a planned offering without the announcement itself acting as a prospectus.

What a confidential filing means

A confidential draft submission lets a company start the review process with the SEC before its paperwork becomes public. The registration statement is filed privately, and the company can revise it in response to the regulator's comments; the document normally becomes public closer to the actual listing. The route is widely used by technology companies, and it does not commit the company to completing an offering.

No offer of securities

The announcement states explicitly that it is not an offer to sell securities and not a solicitation of an offer to buy them. Any offers, solicitations of offers to buy, or sales of securities will be made only in accordance with the registration requirements of the Securities Act. Anthropic gave no timeline for a possible listing and did not disclose financial details.
