Anthropic Plans S-1 Filing at 9 a.m. ET for Potential IPO

Anthropic plans to submit an S-1 registration statement at 9 a.m. ET Monday, Oct. 26 (13:00 UTC), advancing preparations for a potential initial public offering.

The planned filing would take place Monday morning for U.S. readers and at 9 p.m. in Beijing. It is an IPO-related procedural step: Anthropic plans to submit the registration statement to move preparations for a potential offering forward. The filing plan makes a possible AI company listing a notable development for public-market investors.

Anthropic is preparing to file an S-1, while the IPO itself remains a potential future event. The concrete milestone for Monday is submission of that document, rather than completion of an offering. The planned filing gives investors following potential AI listings a specific next step to watch.

The submission is planned for 9 a.m. ET, or 13:00 UTC. The equivalent time in Beijing is 9 p.m. Monday. The filing is the next stated step in Anthropic's potential IPO process.
