Anthropic Said to Hold November 2026 IPO Date as Peers Delay

Anthropic is reportedly maintaining its November 2026 IPO timetable, with investor marketing said to begin in the second week of November, according to Platum. The AI company has not commented publicly on the reported schedule.

Anthropic filed a confidential draft registration statement with the SEC on June 1, 2026. Under SEC rules, a company that files confidentially must make its filing public 15 days before the formal roadshow, so a public filing could come as early as this week.

Valuations cited for Anthropic since September range up to USD 2 trillion, with USD 1.5 trillion also recently reported. In May, the company's stated Series H valuation was USD 965 billion.

Anthropic's offering is the main large deal left in a US IPO market where several tech and AI infrastructure companies have postponed listings. Smart ring maker Oura postponed its IPO in late September, and Australian data center operator Firmus abandoned its listing plan in early October.

Other AI-related listings have struggled. As of the October 16 close, CoreWeave shares had fallen about 25% in a week, while Korean AI cloud company Elise Group, listed on KOSDAQ on October 20 at an offering price of 90,500 won, closed its first day down 32.04% at 61,500 won.
