Anthropic fixed two Claude outages a few days before its IPO

American AI developer Anthropic (planned Nasdaq ticker: ANT) reported on November 13 two outages affecting Claude services. The first issue impacted account logins; the second led to errors in the chatbot and developer tools. The company marked both incidents as resolved on the services status page.

Which services were affected by the outages

As Oninvest reported, Anthropic began investigating after reports of login problems on Claude.ai and Claude Code, a tool for writing and checking code. Later, the company recorded a separate outage: errors occurred in the web version and mobile app of Claude, as well as when calling the models from third-party applications.

Anthropic also separately reported issues with the Claude integration with Microsoft 365, which it attributed to an outage on Microsoft’s side. According to Claude’s status page, the integration began to recover, but some SharePoint search queries still ended in error.

What is known about Anthropic’s listing

Trading in Anthropic shares on Nasdaq is scheduled to begin on November 19. The preliminary prospectus lists a range of $70–78 per share. The upper end of the range implies a valuation of about $1.4 trillion, including potential dilution. The final IPO price is expected on November 18.
