Anthropic Files IPO Registration for Planned Nasdaq Listing
The company plans to list Class A shares as ANT, with pricing slated for Nov. 18 and trading for Nov. 19.

Anthropic said Nov. 12 it filed a registration statement, including a prospectus, with the Securities and Exchange Commission for an initial public offering, advancing its planned U.S. stock market debut.
Anthropic, the developer of Claude, plans to offer Class A common shares on Nasdaq under the ticker ANT. Its published schedule lists Nov. 18 for final pricing and Nov. 19 for the start of trading, following a roadshow that began Nov. 10.
Anthropic's legal notice says investors cannot buy shares until the registration statement becomes effective, so the planned trading date remains subject to that step. The company's IPO page directs prospective investors to a prospectus, a founders' letter and updated financial information. Its legal communication also tells readers to review the registration materials before investing.
The filing and proposed listing are still pending steps. Anthropic had not begun trading under ANT as of Nov. 12.
