🇺🇸Anthropic plans post-September 7 prospectus disclosure while considering shareholder sales and a longer initial-public-offering lockup.

The Information, as relayed by the source messages, reported that Anthropic plans to disclose its initial-public-offering prospectus after September 7. The reported timetable calls for an investor day for prospective investors and research analysts in mid-September.

Anthropic is considering allowing existing shareholders to sell some shares in the offering. Such a structure could provide liquidity to early investors, executives and employees, but the source describes the shareholder-sale provision as under consideration rather than finalized.

The company is also considering a longer-than-usual post-IPO lockup period to manage trading volatility after listing. The reported IPO window was late September or early October, although the source explicitly said the timing could be delayed.
